Missouri IOLTA & Trust Accounting Compliance Guide for Small and Mid-Sized Law Firms

Key Takeaways:

  • Missouri lawyers must keep client funds in special trust accounts (IOLTA or separate interest-bearing accounts) and never commingle them with firm money. The Missouri Bar’s Rule 4-1.15 requires all unearned client funds (like retainers, advance fees, settlement monies) be deposited into a trust account, not the firm’s operating account. Even “flat fees” paid in advance generally belong in trust until earned, with only a narrow exception for small flat fees under $2,000.
  • Strict compliance and recordkeeping are mandatory under Missouri rules. Attorneys must maintain detailed records for each client, perform regular (at least monthly) reconciliations, and retain all trust account records for five years after the representation ends. Missouri requires every lawyer to annually certify compliance with trust accounting rules (or claim an exemption), and banks must report any trust account overdrafts to regulators.
  • Mismanaging a trust account can lead to serious discipline – even disbarment. Missouri’s Office of Chief Disciplinary Counsel (OCDC) investigates trust account violations rigorously. In 2023 alone, the OCDC received 52 overdraft notifications from banks, many stemming from careless trust account management. Mishandling client funds – even unintentionally – is a top cause of ethics complaints and can result in harsh penalties. The good news is that by understanding the rules and following best practices, small and mid-sized firms can stay compliant and protect both their clients and themselves.

What is IOLTA, and Why Does It Matter?

“IOLTA” stands for Interest on Lawyers’ Trust Accounts. An IOLTA account is a type of pooled client trust account where multiple clients’ funds are held together, and any interest earned on the account is remitted to a statewide foundation to fund legal aid and other public service programs. In Missouri, that organization is the Missouri Lawyer Trust Account Foundation (MLTAF), established by the Missouri Supreme Court in 1984 to manage IOLTA interest revenue for charitable purposes.

Every Missouri attorney in private practice who handles client or third-party funds is required to maintain at least one trust account for those funds. The purpose is to safeguard client money and prevent any misuse. By law, client funds cannot be mixed with the lawyer’s own money – this is a fundamental fiduciary duty. If your firm takes a client retainer or advance fee, you must deposit it into a trust account and keep it there until the fee is earned or the expense is incurred, at which point you can transfer it to your operating account. This ensures the money is available for the client’s needs and not used for the firm’s expenses in the meantime.

An IOLTA account is used when the client funds you’re holding are “nominal in amount or to be held for a short period”, such that they wouldn’t earn net interest for the client. For example, a few thousand dollars held for a couple of weeks might generate only pennies of interest – after bank fees, there’s no practical benefit to creating a separate account for that client. Instead, Missouri requires those funds to be pooled in an IOLTA. The interest from all Missouri IOLTA accounts is collected by MLTAF and granted out to support legal services for the poor and improve justice.

On the other hand, if you’re holding a large amount of money for a client or holding funds for a long time, you should use a separate interest-bearing trust account (sometimes called a “non-IOLTA” trust account) for that client’s benefit. Missouri Supreme Court Rule 4-1.155(a)(3) directs attorneys to exercise sound judgment in deciding whether funds should go into IOLTA or a non-IOLTA account. Key factors include the amount of interest the funds could earn and the cost of setting up a separate account. 

In practice, this means if a client deposits, say, $100,000 for a multi-year trust, the interest earned over that period could be significant – so that money should be in its own account with interest payable to the client (or held in escrow for the client’s benefit). Missouri does not allow lawyers to ever keep the interest on client funds themselves – it’s either going to the client or to the IOLTA fund for charity.

Bottom line: IOLTA accounts matter because they are legally required and ethically crucial. They protect clients by keeping their money separate from the law firm’s funds, and they benefit the public by funding legal aid with the interest. Failing to use a proper trust account puts client funds at risk and exposes the lawyer to severe discipline. As one Missouri ethics opinion noted, a lawyer’s fiduciary duty to safeguard client funds is strict – violations can result in suspension or disbarment, regardless of intent.

Missouri’s Trust Accounting Rules: The Basics

Missouri’s rules governing trust accounts are primarily found in Missouri Supreme Court Rule 4-1.15 (“Safekeeping Property”) and Rule 4-1.155 (specific to IOLTA accounts). These rules, along with related comments and formal opinions, lay out exactly what law firms must do to stay compliant. Below is an overview of the key requirements and regulations for Missouri lawyers:

All Client Funds Go Into a Trust Account (No Commingling)

Missouri attorneys must deposit any funds held on behalf of a client or third party into a proper trust account, separate from the lawyer’s own property. This includes advance fee payments (retainers), advance deposits for costs or expenses, settlement proceeds, escrow funds, and any other client money that has not yet been earned or disbursed. Commingling – mixing client money with the firm’s money – is strictly prohibited. The firm’s operating account should only contain earned fees and the firm’s funds, while the trust account holds client funds.

The only exception to commingling is that Missouri (like most states) allows a lawyer to keep a small amount of the lawyer’s own funds in the trust account solely to cover bank service charges or fees. For example, it’s acceptable to deposit a token amount (say $100 of firm money) into the IOLTA to avoid inadvertent overdrafts due to bank charges. Aside from that narrow allowance, every dollar in the trust account must be client or third-party money.

Notably, Missouri updated its rules effective 2019 regarding flat fees paid in advance. In the past, some lawyers treated a flat fee as earned upon receipt (and put it in their operating account), but Missouri now makes clear that “all legal fees paid in advance, whether flat or fixed, and all expenses paid in advance, are required to be deposited into a client trust account and may only be withdrawn as fees or expenses are incurred.” 

The only optional exception is for a truly minimal flat fee: if you charge a flat fee not exceeding $2,000 and will earn it in the near future, you are allowed to deposit that small flat fee into your operating account instead of trust. This is meant to ease burdens for small matters, but use it carefully – if such a fee ends up unearned (e.g. the client terminates the engagement early), you must promptly refund any unearned portion. And regardless, any unearned fee is always subject to refund; Missouri does not permit “nonrefundable” fees that would bypass the trust account.

In short, if you receive money from a client that hasn’t been earned or properly spent on the client’s behalf yet, put it in the trust account. Do not deposit client payments into your business account until you’re entitled to them. Mixing client funds with firm funds – even briefly or by mistake – can lead to discipline. Missouri disciplinary authorities view commingling as a serious breach of fiduciary duty. For instance, depositing a client’s retainer check directly into your operating account, or using your trust account to pay firm bills, are clear violations. Always segregate those funds. (If you ever do accidentally deposit a client check into the wrong account, correct it immediately and document what happened – demonstrating prompt remediation can be important if the mistake is later scrutinized.)

IOLTA Accounts and Approved Financial Institutions

Missouri makes it mandatory that all client trust accounts be interest-bearing (either an IOLTA or a separate interest-bearing account for the client) and that they be held at an approved financial institution. An “approved” institution is one that has been vetted by the Supreme Court’s Advisory Committee and has agreed to meet certain requirements, including: paying interest rates on IOLTA accounts comparable to rates for similar non-IOLTA accounts, and reporting any overdrafts on trust accounts to the OCDC. The Missouri Lawyer Trust Account Foundation maintains a list of over 250 approved banks and credit unions across the state. Before opening a trust account, you should verify that your chosen bank is on the approved list (most major banks in Missouri are).

In practical terms, when you set up your IOLTA account, the bank will require paperwork indicating it’s an IOLTA (often a form provided by MLTAF, including the foundation’s tax ID so interest can be forwarded correctly). The account should be titled in the lawyer or firm’s name with a designation like “Client Trust Account” or “IOLTA Trust Account.” Missouri’s rules explicitly prohibit any setup where the lawyer personally benefits from interest – you cannot, for example, negotiate a special deal to sweep interest to a firm account. It all must go to either the client or the IOLTA charity fund.

For non-IOLTA trust accounts (those set up for a specific client or matter to earn interest for that client), Missouri requires similarly that they be interest-bearing and at an approved institution. Typically, the client’s tax ID or social security number is associated with the account for IRS reporting, and the interest (net of any bank fees) will ultimately go to the client. 

Lawyers should consider factors like the expected duration and amount when deciding on IOLTA vs. a separate account. If there’s any doubt, err on the side of IOLTA for short-term or small sums, and consult Rule 4-1.155 or an ethics advisor for borderline cases. Remember that you have an ongoing duty to monitor the situation – if you initially put funds in IOLTA but they grow or remain longer than expected, you should reassess and possibly transfer to a separate account if it would now earn meaningful interest for the client.

Missouri also has a rule that effectively deems lawyers to consent to oversight measures on trust accounts as a condition of practicing law. Specifically, Rule 4-1.15(a)(2) states that by maintaining a trust account in Missouri, you consent to the bank’s overdraft notification requirement. Missouri implemented a strict overdraft reporting rule in 2010: if any trust account check bounces or the account is overdrawn for any reason, the bank must send a notice to the OCDC. 

This is true even if the bank covers the overdraft or if you have overdraft protection – the idea is that any shortfall in a trust account is a red flag that client funds could be at risk. Once notified, the OCDC will investigate the cause of the overdraft. Many times these investigations reveal innocent mistakes or accounting errors that can be corrected (and may result in education rather than discipline), but they can also uncover serious misappropriation or mismanagement. 

Tip: To avoid ever triggering an overdraft report, be extremely careful with disbursements – never write a trust check unless the funds have “cleared” and been collected by your bank (more on “good funds” below), and regularly monitor the account balance. Some firms arrange for overdraft protection from the firm’s operating account (not from a credit line tied to the trust) as an extra safety net; while that can prevent bounced checks, note that the rule requires a report even if the overdraft was covered, so it’s not a license to be lax. The best approach is zero tolerance for trust shortages.

Required Recordkeeping and Reconciliation Practices

Missouri imposes rigorous recordkeeping requirements for trust accounts. The rules spell out in detail what records you must maintain. In summary, you need to keep “complete records” of all client trust funds, including at minimum:

  • Receipts and disbursements journal – a running register of all deposits into and payments out of the trust account, with the date, amount, source, and description of each transaction. This is like the checkbook register for the trust account, showing every credit and debit. For each entry, it should be clear which client or matter it relates to (e.g., “Deposit – $5,000 from John Doe, settlement” or “Check #101 – $300 filing fee for Jane Smith”).
  • Individual client ledgers – a separate record for each client or matter that lists all funds held on behalf of that client and all payments or withdrawals made for that client. At any given time, your books should be able to tell you exactly how much of the total trust balance belongs to each specific client. It’s critical that the sum of all client ledger balances equals the overall bank balance of the trust account (except perhaps a few dollars of firm funds for bank fees).
  • Source documents and communications – you must keep copies of important supporting documents like retainer agreements, engagement letters for any client whose funds you hold, deposit slips, cancelled or imaged checks, wire transfer confirmations, and any client instructions or authorizations for disbursements. If you pay a client’s bill or a third party from trust, keep a copy of the invoice or written direction. If you transfer earned fees to your operating account, you should have a billing statement or invoice to the client corresponding to that transfer. Essentially, every trust account transaction should be traceable and backed up by documentation.
  • Reconciliation reports – Missouri requires that trust accounts be reconciled “reasonably promptly” after each bank statement is received or available. In practice, this means you should reconcile monthly (since banks issue statements monthly). A reconciliation means you compare the bank’s balance with your internal records and resolve any differences. Missouri expects a three-way (or four-way) reconciliation, meaning: (1) your journal (check register) running balance, (2) the total of all client ledger balances, and (3) the bank statement balance (after accounting for any outstanding checks or deposits in transit) should all match. Some also add a 4th component: your trust account checkbook balance if you maintain one, though that is usually duplicative of the journal. If any discrepancies are found, they must be investigated and corrected immediately. You should keep a record of each reconciliation (date performed and by whom, with any reconciling items noted). Missouri’s rule 4-1.15 requires the lawyer to personally maintain or at least review the reconciliations – even if you delegate the bookkeeping, you are responsible for ensuring it’s done right.
  • Retention period – All of these records must be retained for five years after the end of the representation or the last disbursement of the funds, whichever is later. This is a slightly longer period than some other business records, reflecting the seriousness of trust obligations. If you close your practice or a partner retires, arrangements must be made to preserve those records for the full term. Missouri amended its rules in 2016 to also accommodate electronic recordkeeping: you can keep these records digitally (scans, software, etc.) as long as they are printable on demand and meet the same information requirements. Many firms today use legal-specific accounting software to automatically maintain ledgers and journals (more on that in the Tools section below).

In addition to the above, Missouri’s rules include other specific accounting safeguards. For example, all deposits must be made intact and identified – meaning you shouldn’t split a single check between trust and non-trust accounts or fail to record part of it. If a check from a client includes both a fee and a cost advance, the rule is to deposit the whole amount in trust, then withdraw the earned portion to your operating account (with proper documentation) rather than depositing part directly to operating. 

Also, all withdrawals must be made by check or electronic transfer payable to a named payee (no cash withdrawals, and never a check made out simply to “Cash”). This creates an audit trail of who received the money. The attorney should be the one signing trust account checks or authorizing transfers; according to Rule 4-1.15, only a lawyer admitted in Missouri or a person directly supervised by the lawyer may be a signatory on the trust account. You cannot abdicate responsibility by letting an unsupervised staff member control the trust checkbook – if you do, you’re still accountable for any mistakes or misuse.

Good funds rule: Missouri requires lawyers to wait until deposited funds are “collected” (available as cleared funds) before disbursing against them. In other words, you shouldn’t write checks on a client’s deposit until you’re confident the deposit won’t bounce. Rule 4-1.15(a)(6) forbids disbursing if you have reason to believe a deposit hasn’t actually cleared the banking system. 

A recent comment to the rule suggests that 10 days after the deposit is recorded by the bank is presumed a reasonable waiting period in absence of other information, though a shorter time might be okay for known “good funds” (like a wire transfer or a cashier’s check). The key is to protect against a scenario where, say, you deposit a client’s personal check and immediately cut a trust check to pay a settlement – only to have the client’s check bounce a few days later, leaving a shortfall. That would be an ethics violation. So, ensure a “reasonable period” has passed and/or verification from the bank that funds are collected, especially for large checks.

Lastly, Missouri requires that if there is any dispute over funds in trust, those funds must remain in the trust account until the dispute is resolved. For instance, if a client disputes your fee and part of their money in trust is supposed to go to you as a fee, the disputed amount should not be withdrawn to your operating account until the dispute is settled. This prevents premature use of contested funds.

Annual Certification and Oversight

Missouri takes trust account compliance so seriously that it mandates annual certification by every licensed attorney. Each year when you renew your bar enrollment, you must report whether you have a trust account and are in compliance with Rule 4-1.15, or certify that you are exempt (for example, if you did not hold any client funds during the year). This is known as the Mandatory Trust Account Certification. 

Falsely certifying would itself be a violation – so attorneys need to be honest and ensure they actually are in compliance before checking that box. If you don’t handle any client money, you can claim an exemption (the exemptions are listed in Rule 4-1.15(l) and include categories like judges, government lawyers, or other lawyers who by the nature of their practice don’t hold funds). But if your situation changes (say you start taking retainers), you’d be expected to set up a trust account promptly.

Beyond self-certification, the Office of Chief Disciplinary Counsel (OCDC) and the Missouri Bar have systems to monitor and enforce compliance. We already mentioned the bank overdraft notification program: if your trust account is ever overdrawn, OCDC will know and will inquire. According to OCDC’s 2023 annual report, they received 52 overdraft notices that year and had to follow up on each. Many times the issue was a bookkeeping error or oversight that the lawyer could fix with some guidance, but some cases led to discipline (and in a few instances nationally, repeated overdrafts or intentional misuse of trust funds have led to disbarment).

Missouri may not have routine random audits for all lawyers like some jurisdictions, but the OCDC can audit your trust records if there’s a reason – such as a client complaint, a suspicious overdraft, or as part of an investigation. The Missouri Bar’s Ethics Counsel has published resources emphasizing that “knowing the rules, and consistently applying them, are key to protecting clients’ funds.” 

By following the recordkeeping and accounting practices outlined above, you should be able to pass any audit with flying colors. The goal is not to catch lawyers out on technicalities, but to ensure that client money is safe and handled properly. Conversely, ignorance of the rules is not an excuse – even unintentional mistakes can lead to problems. Missouri case law (e.g., In re Williams, 711 S.W.2d 518 (Mo. banc 1986)) has made clear that mismanagement of trust funds, regardless of intent, can warrant discipline.

To summarize Missouri’s compliance essentials: use a clearly designated trust account at an approved bank, deposit client funds immediately, don’t commingle or borrow from those funds, keep immaculate records, reconcile monthly, and promptly address any issues. Now, let’s look at some common pitfalls and how to avoid them in day-to-day practice.

Common Pitfalls and How to Avoid Them

Even well-meaning attorneys can run into trouble with trust accounting. Small and mid-sized firms, especially those without dedicated accounting staff, should be mindful of these common pitfalls. Below we outline frequent mistakes law firms make with IOLTA and trust accounts, and provide tips on how to avoid each:

Commingling of Client Funds and Firm Funds

One of the gravest errors – and sadly one of the most frequent – is mixing client money with the law firm’s own money. This “commingling” violation can take many forms. Sometimes it’s unintentional, like depositing a check into the wrong account by accident. Other times it happens out of convenience or ignorance: an attorney might deposit a client’s retainer directly into the firm’s operating account, or pay a firm bill out of the trust account. 

Missouri (like all states) strictly prohibits commingling. Rule 4-1.15 requires client funds to be held separate from the lawyer’s funds at all times. The only sliver of allowance is the small amount of firm funds permitted to cover bank fees, as discussed – otherwise, none of your money should be in trust, and none of the client’s money should be in your business account.

Why is commingling so bad? Because if your firm’s money and client money are together, there’s a risk you might spend the client’s portion (even inadvertently) or that it could be seized for your debts. It also makes it hard to account for whose funds are whose. Commingling is viewed as a breeding ground for misappropriation – it’s a short step from commingling to outright conversion of client funds, even if done “just to pay this bill and I’ll replace it next week.” Thus, regulators come down hard on it.

How to avoid it: Establish clear, distinct accounts and never deviate. Have at least two bank accounts for your firm: an operating account for firm money and a trust account for client money. Label them clearly (e.g., “Client Trust Account (IOLTA)” on checks and statements). Train everyone in your office that client funds = trust account, always. 

If you receive a check that includes both client funds and earned fees, deposit it in trust and then transfer the earned portion to operating – do not split-deposit or put it all in operating. Similarly, never pay personal or firm expenses directly from the trust account. If you’ve earned fees and want to pay yourself, first transfer the amount to the operating account (after invoicing the client) and then pay the expense from operating. Essentially, treat the trust account as sacrosanct: it’s only for client-related transactions.

Develop habits like using different colored checks for trust vs operating to avoid confusion. Many firms adopt a two-person rule: one person prepares or initiates trust transactions and another person (often the attorney/partner) must review and sign off. This double-check can catch commingling mistakes before they happen. If you ever mistakenly deposit or withdraw from the wrong account, correct it immediately

Document what occurred and how you fixed it – this can be vital if the incident is later examined. By staying vigilant and creating separation in all procedures, you’ll eliminate most commingling issues. Remember, in Missouri even a temporary commingling (like holding a client’s check in your office safe for too long or “just until it clears”) is not allowed – client funds belong in the trust account right away and nowhere else.

Inadequate Record-Keeping

Poor record-keeping is a leading cause of trust accounting troubles. Given the detailed requirements Missouri has, it’s easy to fall short if you don’t have a good system. Common mistakes include: not keeping individual client ledgers (so you lose track of how much each client has on deposit), failing to record transactions as they happen, neglecting to keep copies of deposit slips or cancelled checks, or simply relying on a checkbook register that doesn’t capture all necessary info. Without proper records, a lawyer might think the trust account has more money than it truly does (if, say, they didn’t note a withdrawal) or might mistakenly use one client’s funds to pay another client’s bills because the balances weren’t clear.

How to avoid it: Implement a reliable bookkeeping system specifically for the trust account. You can do this manually with a ledger book and journal, or use software – but either way, commit to recording every single transaction in detail. Maintain the required receipts and disbursements journal and a separate ledger for each client. 

For each deposit, write down the date, amount, and source/client; for each disbursement, note the date, amount, recipient, and which client’s funds are being used (with a short description like “filing fee” or “paid to Dr. Jones for expert report”). Keep a photocopy or scan of every check you write and every important document (if you send a settlement check to a client, save a copy of the check and the settlement statement; if you receive a cashiers’ check for a closing, copy it before depositing).

Many lawyers find that using legal accounting software or the trust module in practice management software greatly simplifies this task. Such software will automatically update client ledgers when you enter a transaction and can even generate reports to show you if anything is off. For example, with LeanLaw’s trust accounting integration with QuickBooks, you record a client payment once and the system posts it to the right client ledger and bank account simultaneously. Whether manual or electronic, choose a system that you will actually use consistently. Set a routine – e.g., every Friday, or upon receiving any trust funds – to update the ledgers and file away documents.

Additionally, periodically review your records for accuracy. Don’t just trust that because you (or your staff) wrote it down it must be right. For instance, each month when reconciling, pick a random client ledger and trace the transactions, ensuring each corresponds to a bank deposit/withdrawal. This internal audit can catch if something was accidentally not recorded or mis-recorded. Good record-keeping habits are your friend – not only to stay compliant, but to protect yourself if anyone ever questions your handling of funds. If you can immediately produce a detailed ledger and receipts showing exactly where a client’s money went, you build trust with clients and regulators alike.

Failing to Reconcile the Account Regularly

Not performing regular reconciliations is a recipe for disaster in trust accounting. Reconciliation means comparing your internal records with the bank’s records to make sure they match. If you neglect this, small errors can snowball over time. For example, say a $100 bank fee hit your IOLTA and you didn’t realize – your client ledgers might sum to $100 more than what’s actually in the account. 

Or maybe a check you wrote last month never got cashed; if you’re unaware, you might think you have more funds for a client than you really do once the check eventually is cashed. Without reconciliation, these discrepancies can linger. In the worst cases, a lawyer might not notice a trust shortfall until a client complains or a check bounces, by which time multiple clients’ funds could be entangled.

Missouri rules effectively mandate reconciliations with each bank statement (at least monthly), yet busy lawyers sometimes procrastinate on this task. That’s risky – the longer you go unreconciled, the harder it is to identify and fix issues.

How to avoid it: Reconcile the trust account every single month, without exception. Treat it as sacred as paying your rent – a non-negotiable monthly event. As soon as the bank statement is available, compare the bank balance to your internal books. First, adjust the bank balance for any checks you’ve written that haven’t cleared and any deposits that haven’t posted yet (outstanding items). 

Then the adjusted bank balance should exactly equal the balance per your records (your running checkbook/journal balance). Also, verify that this matches the total of all client ledger balances. This is the classic “three-way reconciliation”. Many modern software tools can generate a three-way reconciliation report at the click of a button, which is helpful – but even if you use software, you need to review the report.

If anything doesn’t match up, investigate immediately. Common culprits are: arithmetic errors in manual records, a transaction recorded under the wrong client, bank charges or interest that you didn’t record, or less commonly, a bank error. By catching it promptly, you can correct the ledger and make any necessary transfers (for example, if a bank fee came out of client funds, you must replenish that from the firm’s money as soon as you spot it). Never carry unexplained discrepancies forward; that’s essentially letting a problem fester.

It’s also wise to have a second set of eyes on reconciliations. In a larger firm, someone other than the person who writes the trust checks should review the monthly reconciliation (an internal audit role). In a small firm or solo practice, if you prepare the reconciliation yourself, consider asking an outside bookkeeper or a colleague to review it periodically, or at least step back and review your own work critically. Missouri’s emphasis on reconciliation is there because this process will catch most issues – it’s your early warning system. Regular, disciplined reconciliation keeps your trust account accurate and gives you confidence that you aren’t inadvertently using the wrong funds. It’s far easier to correct a $50 error one month later than to find a $5,000 hole two years later.

Improper or Early Disbursement of Funds

Another common pitfall is disbursing client funds inappropriately – either too soon, or to the wrong party, or in the wrong amount. Trust accounts often see a lot of movement: money in, money out to pay client expenses, settlements distributed, fees taken by the firm, etc. Mistakes here can be costly. Some examples of improper disbursement include:

  • Paying one client’s obligations with another client’s money. This might happen if Client A needs a disbursement but their funds haven’t cleared, so someone uses Client B’s funds (currently sitting in the IOLTA) “just temporarily” to cover it. This is essentially borrowing from Peter to pay Paul – and it is a serious violation (it’s considered conversion of Client B’s funds, even if you intend to replace it).
  • Withdrawing your fees before they are earned or without client authorization. For instance, taking funds out of trust for your attorney fee before you have sent the client an invoice or before you’ve actually completed the work. Missouri requires that fees be earned and usually that the client has been billed (or otherwise consented) before you move that money to your own account. Taking fees out early is viewed as taking client property – it’s not yours until it’s earned and accounted for.
  • Over-drafting a client’s sub-account. If you write a check on behalf of a client that exceeds what that client had on deposit, you’ve effectively used other clients’ money to cover the difference. Even if the overall account had funds, that client’s ledger went negative, which is a red flag of mismanagement.

How to avoid it: Institute strict internal controls for any trust withdrawals or transfers. Never withdraw or disburse more for a client than that client has in the trust account. This sounds obvious, but it can happen if you lose track – again, good records and checking the ledger balance before cutting a check are key. If a client doesn’t have enough to cover a cost, ask them to replenish the trust; do not “borrow” from another client’s funds.

When it comes to paying yourself legal fees from the trust, do it the right way: wait until you have earned the fee, send the client an invoice or billing statement showing the fee, and (assuming no dispute) then transfer the fee from trust to your operating account. Missouri’s comments suggest that disbursing fees to the lawyer within about 30 days of invoicing is considered reasonably prompt (so you’re not holding earned funds in trust too long, which can also be problematic). 

But the key is don’t take it early. If the client is billed on January 31 and you earned the fee, you might transfer it in early February – but not on January 15 before the work was done. Always get past the “earned and invoiced” milestone. If a client challenges a fee, hold off on moving those funds until resolved.

A good practice is requiring approval for trust disbursements by a responsible attorney. For example, you might have a firm policy that any trust check over a certain amount (say $1,000) needs two signatures or partner approval. In a solo practice, that could mean you at least double-check the ledger before signing any large check. Many banking systems allow dual-control for electronic transfers as well. These checks and balances reduce the chance of a unilateral mistake or wrongdoing.

Also, document every disbursement clearly. On each check’s memo line, write the client name and what it’s for (“John Doe – settlement proceeds” or “Jane Smith – expert witness fee”). If you ever need to justify a disbursement, you have it right there. Keeping a paper trail (e.g. copy of the invoice you paid, letter transmitting a settlement check to the client) will cover you if questions arise.

Lastly, never treat the trust account as a slush fund or “backup” for your expenses. “Borrowing” even $100 from trust for a short time is forbidden. Lawyers have been disbarred for dipping into trust accounts to cover cash flow, even if they intended to pay it back. It’s simply not worth it. If you find yourself tempted to use client funds because your firm is short on money, recognize that doing so is likely the quickest way to lose your law license. Keep a strict bright line: client money is off-limits until it becomes legitimately yours.

Lack of Oversight and Segregation of Duties

In many small firms, one person (maybe a paralegal or the office manager, or sometimes the attorney themselves) handles almost all aspects of the trust account. They receive client checks, deposit funds, record the transactions, write trust checks, and reconcile the statements. While it’s common due to limited staffing, this lack of segregation of duties can increase the risk of errors or even fraud going unnoticed. If no one else is looking at the trust records, a simple mistake might not be caught, or worse, an unscrupulous employee could divert funds without detection. Even attorneys have been caught embezzling client funds when they had sole control and were under financial pressure.

How to avoid it: Wherever possible, divide responsibilities related to the trust account. In an ideal world (like big firms), different people would 1) approve disbursements, 2) handle the physical banking (deposits, writing checks), 3) maintain the books, and 4) perform reconciliations. Small firms may not have four people for four roles, but aim for at least a second pair of eyes in the process. 

For example, if a non-lawyer bookkeeper enters all the transactions and does a preliminary reconciliation, the lawyer or partner should review the ledger reports and bank statements monthly. The reviewing lawyer should actually look at a sample of cancelled checks or deposit images – ensuring, for instance, that a check supposedly paid to “Court Clerk for filing fee” wasn’t actually written to someone else. Many banks now include check images with the statements, making this easier.

Another strategy: have each attorney who is responsible for certain clients periodically review those clients’ trust ledgers. For example, if Partner A manages the Doe matter, they should see how much money Doe has in trust and what transactions have occurred, rather than leaving it entirely to accounting staff. This not only keeps attorneys aware, but also serves as a cross-check that transactions were appropriate.

Some firms invite an outside auditor or CPA to do an annual audit of the trust account. This can be a prudent investment, especially if your trust account is very active. The auditor can verify that the books are in order and perhaps catch any weaknesses in your procedures.

The key principle is no one person should be the only one with knowledge and control of the trust account. If you’re a true solo with no staff, this can be challenging – but even then, consider having a mentor or contract bookkeeper glance at your records once or twice a year. And always separate duties as much as you can: for instance, you as the lawyer make all disbursement decisions, and your assistant only prepares the checks for your signature. Or vice versa, if you as the lawyer do the bookkeeping, have the bank send duplicate statements to a trusted colleague to look over. These measures protect not just the clients but also you – they make it far less likely that a mistake or defalcation will slip through for long.

Managing Too Many Trust Accounts

This pitfall is more relevant to growing firms or those handling many large client funds. Managing too many separate trust accounts can become unwieldy. Some firms open a new trust account for every big case or client (especially if each is interest-bearing for the client’s benefit). For example, a personal injury firm might have separate escrow accounts for each major settlement they’re holding before distribution. 

While this isn’t inherently wrong – it might even be required if those funds are substantial – it can create a logistical nightmare. Each account must be tracked and reconciled. Funds might accidentally end up in the wrong account. It’s also harder to keep an eye on the overall picture when money is fragmented across 10 different bank accounts.

How to avoid it: Streamline your trust account structure where possible. Missouri allows pooled IOLTA accounts for a reason – it’s often simpler to maintain one primary IOLTA for all the routine client funds, rather than opening dozens of separate accounts. Only open a dedicated account when it’s truly necessary (i.e., the client’s funds are so large or will be held so long that separate interest is justified). 

Even then, consider using as few accounts as practical. It’s possible to pool multiple clients in one interest-bearing account if you have sophisticated sub-accounting to allocate interest, but that is complex and usually not worth the hassle unless you have a software system doing it. Most small firms will have one IOLTA and maybe a handful of separate accounts for unique situations.

If you do manage multiple trust accounts, consider keeping a master ledger or spreadsheet summarizing all of them, so you don’t lose track of the forest for the trees. And apply the same recordkeeping and reconciliation rigor to each account individually. Sometimes lawyers focus on the main IOLTA and forget to reconcile a smaller separate account, which can lead to a surprise problem. Treat every client trust account with equal care.

In summary, complexity can breed error. Keep your trust account system as simple as you can while still meeting clients’ needs. Many mid-sized firms find they only need one or two trust accounts in total (one IOLTA for general use and perhaps one separate interest-bearing account for a large ongoing case). That is far easier to manage than juggling 20 accounts. If you find yourself opening a new trust account every week, pause and evaluate if that’s truly necessary or if an existing account could serve. Balancing client interests with administrative practicalities is key here – you must do what’s right for the client, but also ensure you can properly oversee it.

With awareness of these pitfalls and proactive measures to avoid them, your firm can maintain a spotless trust accounting record. Next, we’ll highlight some tools and resources that can further simplify compliance and help you implement these best practices.

Tools and Resources to Simplify Trust Accounting

Trust accounting may sound old-fashioned or cumbersome, but modern tools and resources can make it much easier to manage – especially for small and mid-sized firms without in-house accountants. Taking advantage of these can streamline your workflow and provide additional safety nets for compliance:

Legal-Specific Accounting Software

One of the best investments for a law firm is software designed for legal billing and trust accounting. General bookkeeping software can work, but it may not enforce the special rules that attorneys must follow. In contrast, legal-specific accounting software (or law practice management software with trust features) is built with those rules in mind.

For example, LeanLaw – a legal billing and trust accounting solution – integrates with QuickBooks Online to automate many trust accounting tasks. Using such software, you can record client trust transactions with just a few clicks, and the system will update all the ledgers and journals in the background. In LeanLaw’s case, it customizes QuickBooks for law firms, providing a user-friendly interface that still maintains proper double-entry accounting behind the scenes. 

The big advantage of specialized software is that it acts as a safeguard: it can be configured not to allow certain violations, like drafting a check that exceeds the client’s balance, or it can force you to input required details for each transaction (so you don’t accidentally omit the client name or purpose). Many programs also generate three-way reconciliation reports automatically and flag any discrepancies for you.

Other features to look for include: real-time client balance dashboards (so at a glance you see how much each client has in trust), alerts for low balances or potential overdrafts, the ability to print checks with all the necessary info, and integration with your general ledger so that when you earn a fee it moves from trust to income on the books seamlessly. The goal is to reduce manual effort and human error. Even a simple mistake like typing the wrong amount could be caught by software that double-checks balances.

While there is a learning curve to any new software, most cloud-based legal accounting apps today aim to be intuitive. They also keep your data backed up and secure, which can be a relief compared to managing piles of paper ledgers. The key is to choose a solution that fits your firm’s size and budget. LeanLaw’s trust accounting feature, for instance, is geared towards small and mid-sized firms that want robust trust compliance without needing a full-time accountant. 

But whatever you use, make sure it actually helps you meet Missouri’s requirements – the software should support three-way reconciliation, detailed client ledgers, and easy report generation for audits. If you’re not ready for specialized software, at least use QuickBooks with a proper chart of accounts for trust funds (LeanLaw and similar tools can enhance QuickBooks in this way). Using more than just a manual spreadsheet will pay off in time saved and fewer mistakes. Essentially, the right software can put much of your trust accounting on autopilot while ensuring you adhere to Missouri’s rules.

Missouri Bar and OCDC Resources

Don’t overlook the free resources provided by the Missouri Bar and the Office of Chief Disciplinary Counsel. Missouri has a Practice Management division and Ethics Counsel that have published guides and checklists to help lawyers with trust accounting. Here are a few particularly helpful resources:

  • Missouri Lawyer Trust Account Handbook – This comprehensive handbook (available from the Missouri Lawyer Trust Account Foundation) is a practical guide to Missouri’s trust account rules. It covers everything from what counts as “trust funds,” how to open an IOLTA, what records to keep, and includes sample forms and even a manual ledger template. It’s an excellent reference if you need to dig into a specific question. For example, it has a handy checklist for IOLTA account setup and a sample three-way reconciliation form. Because it is tailored to Missouri rules, it can clarify state-specific nuances (like the $2,000 flat fee exception, or handling credit card fees in trust).
  • Trust Account “Self-Audit” Checklist – The Office of Chief Disciplinary Counsel has produced a self-audit checklist for lawyer trust accounts. This is essentially a series of yes/no questions to verify you are following all required procedures. It asks about things like: Do you reconcile every month? Do all withdrawals have proper documentation? Are records kept 5 years? By going through the checklist, you can identify any areas where your practice might be deficient before it becomes an issue. It’s a great annual exercise, even if you think you’re doing fine.
  • Informal Ethics Opinions / Ethics Hotline – Missouri’s Legal Ethics Counsel offers an informal advisory opinion service. If you’re ever unsure about a trust account situation (e.g., how to handle an unclaimed client refund, or whether a certain credit card processing setup is permissible), you can request an informal opinion from the Ethics Counsel (through the Missouri Bar) confidentially. They also have an ethics hotline you can call for quick guidance. While they won’t give binding rulings over the phone, they can guide you on best practices and how the rules likely apply. This is similar to what Florida’s LegalFuel offers, and it can be a lifesaver when facing a tricky scenario. Getting advice before acting can save you from a potential violation.
  • Missouri Bar CLEs and Articles – The Missouri Bar often hosts CLE courses on trust accounting and publishes articles in the Journal of The Missouri Bar on ethics updates. For instance, when rule changes occurred in 2019, the Bar published an article explaining the new flat fee rule in plain language. Attending a CLE or reading these materials can keep you up to date on any changes (such as new recordkeeping rules effective 2016, etc.). The Bar’s website (mobar.org) has a Practice Management section with resources for financial management as well.
  • MLTAF (Missouri IOLTA) Support – The Missouri Lawyer Trust Account Foundation (MLTAF) itself can be a resource. Their website has a Q&A section for attorneys, forms for things like notifying your bank about IOLTA status, and contacts if you have questions about setting up an account. While they focus on the IOLTA program (interest remittance, eligible banks, etc.), they can often assist with general inquiries or point you in the right direction.

By leveraging these tools and resources, a small or mid-sized firm can manage trust accounting with confidence. Technology can handle the heavy lifting of tracking and math, while bar resources can provide education and guidance. In combination, they help ensure that compliance isn’t a constant source of stress. Instead of fearing an audit or oversight, you can be audit-ready at all times.

To wrap up, remember that trust accounting is ultimately about protecting your clients. When done correctly, it also protects you and your firm’s reputation. In fact, some lawyers find that having a well-managed trust account system becomes a selling point – it demonstrates your professionalism and reliability to clients (who often worry about how their retainers are handled). With the foundation laid out in this guide, Missouri law firms of any size can maintain compliant IOLTA accounts and avoid the common pitfalls. Keep the rules handy, instill good habits in your daily practice, and don’t hesitate to use available tools or seek advice when in doubt.

Below is a quick FAQ addressing some common questions that many attorneys have about trust accounting in Missouri:

FAQ: Common Missouri Trust Accounting Questions

Q: Do I need to open an IOLTA account if I’m a new attorney who isn’t handling client money yet?

A: If you don’t handle any client or third-party funds (for example, you practice in-house or do work that doesn’t involve client payments), you can certify as exempt from the trust account requirement. However, the moment you anticipate receiving client funds – even a small retainer – you should set up an IOLTA account at an approved bank. It’s often wise for a new solo practitioner to open a trust account preemptively, so it’s ready when needed. 

Remember that all Missouri lawyers must annually either report a trust account or claim an exemption. If you unexpectedly receive client funds without an account in place, you could scramble and risk non-compliance. So, if there’s any chance you’ll receive advance fees, go ahead and establish the IOLTA. There’s no harm in having one open even if it sits empty for a while.

Q: Can I use one trust account for all my clients, or do I need separate accounts for each?

A: You can (and typically should) use one pooled IOLTA account for all clients’ small or short-term funds. That is the purpose of IOLTA – to aggregate multiple clients’ funds in one account. You do not need (or want) a separate IOLTA for each client. The important thing is that your records internally distinguish each client’s portion. 

For larger or long-term matters, you might open a separate “non-IOLTA” trust account to hold that single client’s funds (so they earn interest for the client). But even then, you might have, say, one IOLTA and a couple of separate accounts for specific clients – not dozens of accounts. Having too many trust accounts is burdensome (each must be tracked) and not required unless circumstances demand it. Most small firms maintain one IOLTA account for the majority of client funds. 

Only if a particular client’s deposit is significant enough that the interest would meaningfully benefit the client should you consider a separate account. And if you do that, it’s often one account per such client, not multiple. Always weigh the administrative complexity against the benefit to the client. Missouri’s rule gives you discretion to decide using factors like amount and duration of funds.

Q: What exactly qualifies as “trust funds” that have to go in the trust account?

A: Generally, any money that belongs to a client or third party and is in your possession in connection with legal services is a “trust fund.” Common examples include: advance fee payments (retainers) until you earn them, advance deposits for costs/expenses until used, settlement or judgment proceeds before distribution, escrow funds for transactions (real estate closings, etc.), and funds held awaiting a dispute resolution (like disputed divorce property funds). 

Missouri Rule 4-1.15 covers all those categories. Funds that are already earned (like a fee for work you’ve completed and billed) are not trust funds and should go straight to your operating account. Also, flat fees or retainers that are termed “nonrefundable” by contract are still considered client funds until earned under Missouri’s view – so those go in trust as well. 

On the flip side, a true general retainer (paid solely to secure your availability, not for specific future services) might be considered earned on receipt, but those are rare and you’d want an ethics opinion before treating it as non-trust. When in doubt, err on the side of putting funds in trust. It’s safer to put money in trust and later transfer it out than to mistakenly deposit client money in your own account. Remember: advance fees = trust account; earned fees = operating account.

Q: How much of my own money can I keep in the trust account to pay bank fees?

A: Only a minimal amount necessary for bank charges – typically no more than what you’d reasonably need for a month or two of fees. Missouri doesn’t specify an exact dollar limit, but commonly it’s in the range of $100-$200 or so, just to cover things like monthly maintenance charges, wire fees, check printing costs, etc. 

Some attorneys keep $0 of their own money in trust by arranging with the bank to have fees charged to a separate operating account – that’s even cleaner. But if you do deposit a small cushion, keep it small and periodically review it. You should not be routinely paying large fees from an IOLTA anyway, since IOLTA accounts in approved banks often have no service fees or have them offset against interest. 

Never use the trust account as a savings account for the firm. The rule allows only enough firm funds to avoid inadvertent overdraft from bank fees. If, say, you ended up with $500 of earned interest in a non-IOLTA account that should go to the client or charity, that $500 is not “your” money to leave there – it must be remitted appropriately. In short, keep the firm’s portion to the bare necessity for fees, and no more.

Q: What happens if a client’s trust check bounces or there’s an overdraft in the trust account?

A: If a trust account check bounces (is returned for insufficient funds) or the account is overdrawn, the bank will send a notice to the Office of Chief Disciplinary Counsel under Missouri’s overdraft reporting rule. This will likely trigger an inquiry or audit by OCDC. You (or your firm) will have to explain what happened and provide records. If it was a bank error or an innocent mistake that you quickly corrected, it may be resolved with education or a warning. 

However, if the overdraft reveals misuse of funds or chronic poor management, it can lead to disciplinary action. From the firm’s perspective, when you discover an overdraft or bounced check, immediately identify the cause. Perhaps a check was written on uncleared funds, or a math error led to a client ledger deficit. Fix any shortfall right away (even if that means the firm depositing its own money to cover a mistake – noting that the firm money in that case is to remedy an error, not to stay mingled with client funds). 

You should also notify the affected client if appropriate (e.g., if a check to a client bounced). An overdraft is a serious red flag. OCDC’s reports show dozens of such notifications each year. Avoid it by being extremely cautious with disbursements (wait for “good funds,” double-check balances before writing checks). If one does occur, be prepared to demonstrate that no client lost money and that you’ve implemented safeguards to prevent a repeat.

Q: How long must I keep old trust account records, and what should I do with them when the time comes?

A: You must keep trust accounting records for at least five years after the termination of the representation or the last disbursement of funds, whichever happens later. That includes ledger books, journals, bank statements, cancelled checks, deposit slips, reconciliations, and any client records related to trust transactions. After five years, if you’re confident there’s no litigation or audit pending involving those records, you may destroy them (shred paper records or delete securely if electronic). 

Some lawyers choose to keep them longer (seven or ten years) out of caution, and that’s fine – the five years is a minimum. Make sure even if you retire or your firm closes that someone retains the records for that period. It’s good practice to inform clients in your engagement letters that you will destroy trust records after the retention period, just so it’s on record. One caveat: if the client’s funds were property of a minor or under a long-term trust, you might consider keeping records longer due to the possibility of issues arising later. But generally, five years is the rule. Be mindful also to keep records organized by closing date so you know when each file’s clock runs out.

Q: If a client disappears or doesn’t cash a refund check, what do I do with their trust money?

A: Missouri, like most states, has provisions for unclaimed or abandoned client funds. If you have money in trust that you can’t return because you can’t reach the client (or they won’t cash the check), you can’t just keep it indefinitely. First, you must make diligent efforts to find the client or rightful owner. Document your attempts (letters, emails, calling last known number, etc.). If truly unable to locate them after a reasonable time, Missouri’s Rule 4-1.15 and state law will require you to eventually remit the funds to the Missouri State Treasurer’s Unclaimed Property Fund under the unclaimed property statutes, or potentially to the Missouri Bar Foundation (some states allow small amounts to go to the bar foundation/IOLTA fund as “abandoned funds”). 

Before doing that, you’d typically have to give notice (to the extent possible) and perhaps get permission from OCDC or a court, depending on the amount. The Missouri Bar’s trust account resources or ethics opinions likely outline the specific steps. Importantly, those funds should stay in your trust account until you turn them over to the appropriate entity. Do not transfer them to your own account. Also, keep a ledger for “Unclaimed Funds for [Client]” so you remember what that money is and when you sent it to the state. Missouri requires keeping records if you escheat funds. 

As a practical tip, many firms run a ledger review at year-end to catch any balances for closed cases. If a client hasn’t cashed a check, you might stop payment on it and hold the funds while you try contacting them again. The goal is to reunite clients with their money, but the law provides a mechanism to clear truly unclaimed funds after a certain period (usually five years in Missouri for unclaimed property). Check Missouri’s specific rules or an ethics opinion for the process, but whatever you do, don’t use the money yourself – it’s not a “bonus” for the firm; it either belongs to the client or, eventually, the state’s unclaimed property fund for safekeeping.

Q: Can I accept credit card payments or online payments into a trust account?

A: Yes, you can accept credit card or electronic payments from clients for funds that need to go into trust (like retainers), but you must handle them carefully. The primary concern is credit card processing fees – these fees should not be deducted from client money in the trust account because that would mean the client’s balance is shorted to pay the processor. There are a couple of solutions: one is to use a payment processor or service designed for legal trust payments (many exist) that can direct the fee portion to your operating account and the net to trust. 

Another is simply to have the client pay into a separate merchant account that deposits into trust, and then promptly replace any fees charged with firm funds. The easier route is a legal-specific payment solution (for example, LawPay, Gravity Legal, etc.) which knows how to split fees. Missouri’s rules allow electronic transfers and even credit card transactions, but you must keep records of each such transfer and ensure confidentiality and security (credit card data should be handled per PCI standards). The key ethical point: if a client pays $1,000 by card for a retainer, the full $1,000 needs to end up in the trust account on the client’s behalf. If the processor takes $30 in fees, that $30 must come from the lawyer’s funds, not from the client’s trust balance. 

Many state bar opinions approve of credit card trust payments as long as this is respected. Also, never allow chargebacks to pull from the trust account if possible – ideally, the arrangement should be that chargebacks are taken from your operating account to avoid any depletion of other clients’ money. In short, yes you can do it (and it’s often good customer service to allow it), just set it up correctly. Most modern practice management or payment platforms have a trust-compliant option. When in doubt, consult an ethics opinion or call the Missouri Bar’s hotline to confirm your specific setup is okay.

Q: What are the consequences if I make a mistake with the trust account?

A: It depends on the nature of the mistake, but consequences can range from minor to very serious. If it’s a small recordkeeping error that you catch and fix, there may be no external consequence. If an audit or investigation finds a violation that didn’t cause harm – say you were a bit slow on a reconciliation or you kept poor records but no funds were actually misspent – you might get a caution or reprimand, and you’ll be required to correct practices. The Missouri OCDC often uses diversion programs or educational resolutions for minor, unintentional violations. 

However, if client funds were misused, even inadvertently, the discipline can escalate. Suspension of your license is common for trust accounting misconduct, and outright disbarment can occur for knowing misappropriation or repeated gross negligence. Missouri treats the safeguarding of client funds as a core ethical duty; violations strike at the heart of trust in the profession. One often-cited maxim is that misappropriating client money is one of the fastest ways to get disbarred. Even commingling alone, if prolonged, can result in serious discipline because it indicates a disregard for the rules. Each case is fact-specific, but precedent shows little tolerance for significant trust breaches. 

Apart from formal discipline, there’s also the potential for civil liability – a client could sue you for negligence or conversion if they suffer loss, and your malpractice insurance might not cover intentional acts. In extreme cases, criminal charges have been brought for attorneys who stole client funds. The bottom line is: take any trust account mistake as a very big deal, correct it, and learn from it. If OCDC ever contacts you about an issue, cooperate fully and demonstrate what you’ve done to fix it. The best “consequence” is never having one – which is achievable if you rigorously follow the rules and best practices outlined in this guide.


By staying informed about Missouri’s IOLTA and trust accounting requirements and using prudent practices, your small or mid-sized law firm can confidently manage client funds in compliance with the Missouri Bar rules. Trust accounting may require diligence, but it ultimately protects your clients and your law license. When in doubt, always put the client’s interest first and seek guidance. Compliance is not just a bureaucratic chore – it’s part and parcel of ethical lawyering in Missouri. With the information and tips provided here, you’re well on your way to mastering IOLTA and trust accounting in the Show-Me State. Good luck, and happy (compliant) accounting!
