What Is Trust Accounting? A Guide for Law Firms

What is trust accounting?

Trust accounting is how a law firm safeguards money it holds for clients or third parties, such as advance fees and settlement proceeds. The firm keeps that money separate from operating funds, records each client’s share in an individual ledger, and regularly reconciles its records with the bank. The exact duties depend on the jurisdiction and the funds involved.

For firms comparing trust accounting software for law firms, the useful test is whether the software supports client-level ledgers, fund separation, three-way reconciliation, and a clear connection to the general ledger. LeanLaw handles that financial workflow in QuickBooks Online and explains the full product scope on the trust accounting page.

How does trust accounting work for law firms?

A firm receives client funds, deposits them into the appropriate trust account, records the deposit on that client’s ledger, and makes only authorized disbursements. When fees are earned and billed, the firm may transfer the permitted amount to operating. It then checks the bank, books, and client ledgers for differences. The example below shows that flow; local rules control the details.

Why do law firms hold funds in trust?

Trust accounting has a long history rooted in the legal profession’s commitment to safeguard client funds and their trust and confidence in the legal system.

Building and keeping a client’s trust is one of the most important things that attorneys need to learn to do and through good trust accounting, this can be possible.

The concept of trust accounting emerged as a response to the need for a systematic and transparent approach to managing client funds.

Attorneys are often entrusted with significant amounts of money, whether it’s for future settlements, up-front retainers, or to hold funds for other legal matters.

Here are the most common reasons that an attorney or law firm may have to handle a client’s funds:

• At the beginning of representation when initial funds are received: In this situation, attorneys will place “unearned income” into the trust, including upfront fees, retainers, or cash advances. Again, by law attorneys can’t use this money for operations and it must be held in trust until the completion of their case or matter.
• When and if there is payment from a settlement: Transactions revolving around real estate for example must pass through a trust account and must not be commingled with operating accounts.
• When an attorney acts as a fiduciary on behalf of a client or the client’s estate: Similar to settlement, these “third party funds” that are handled by an attorney when acting as a fiduciary must remain separated.

The responsibility to protect and account for these funds has led to the present-day development of trust accounting compliance and regulations.

Over the years, trust accounting has evolved to address the changing needs and complexities of the legal profession. Legal bodies and regulatory authorities have established rules and guidelines to ensure the proper handling of client funds.

Though some of these rules vary by jurisdiction, it’s common for some basic ones to apply to most law firms.

Most jurisdictions make it clear that any practicing attorney or law firm that they oversee must manage their client’s funds by holding them in bank accounts that are separate from the firm’s operating account, maintain accurate records, conduct regular reconciliations, and provide clients with periodic accounting statements.

Which trust accounting rules apply?

State bar rules on trust accounting don’t change often, but enforcement and reporting expectations keep tightening. Heading into 2026, most state bars are leaning harder on three things: mandatory three-way reconciliation on a monthly (not just annual) cadence, electronic recordkeeping that can produce an audit trail on demand, and clear rules for how — and how quickly — IOLTA interest gets remitted to the state’s lawyer trust account program. A growing number of states now require attorneys to register their trust accounts directly with the bar, and several have added or tightened continuing-education requirements specifically on trust accounting. None of this changes the core obligation (segregate client funds, reconcile regularly, keep clean records), but it does mean manual, spreadsheet-based trust accounting is a riskier bet than it used to be. Since requirements vary by state, check your jurisdiction’s specific rules — LeanLaw maintains state-by-state IOLTA and trust accounting compliance guides covering the current rules for most states.

Traditional manual methods of record-keeping and tracking transactions have now given way to sophisticated trust accounting software solutions. These software tools automate many trust accounting tasks, making the process more efficient, accurate, and reliable.

What is IOLTA?

IOLTA stands for Interest on Lawyers’ Trust Accounts. It generally allows qualifying short-term or small client funds to be pooled in a trust account whose interest supports legal aid. Funds that can earn meaningful interest for one client may need a separate account, depending on local rules. An IOLTA account still requires individual client records and regular reconciliation. See IOLTA compliance for the workflow.

How does money move through a trust account?

Let’s look at an example of how a client’s funds should be properly handled.

1. A client or third-party (such as an insurance company or another attorney) hands your office a check for money that is not your money. This could be things such as unearned legal fees, settlement funds, etc.

2. You deposit this money into your firm’s trust account. Depending on the trust accounting rules and regulations in your jurisdiction, if the sum is large enough and belongs to a single client, you may be obligated to open a new interest-bearing separate account solely for that client. Otherwise, these funds will go into your normal, pooled client’s trust account.

3. As some of these funds are earned by you, or are required to pay off fees or expenses, you will typically write a check from your trust account to pay the amount into your operating account (or you may be able to electronically transfer yourself your earned fees - again, depending on the rules governing trust accounts in your area.)

4. When a case is settled, and all claims are paid, any of the remaining funds will then be refunded to the client and you will no longer be allowed or responsible to manage assets for that particular client or case.

Though this is a fairly simplified explanation of the ways in which a client’s trust assets should be managed, it gives you a basic idea of what is entailed.

Obviously, the whole process becomes much more complex with the more clients a firm has, and the more trust transactions that need to take place.

But either way, it’s imperative that your firm knows how to manage trust accounts and properly handle any and all money that should be deposited and withdrawn from them.

When can funds leave a trust account?

Money leaves trust when the firm has a documented, permitted reason: returning funds to a client, paying an authorized third party, or transferring earned fees to operating after billing. Before a payment, check the client or matter ledger, the available balance, and the instructions governing the funds. A pooled account may contain enough cash overall while the specific client’s ledger does not.

Record the payment against the correct ledger and keep the invoice, authorization, settlement statement, or other supporting record. If the bank transaction and ledger entry are made at different times, track the outstanding item for the next reconciliation. The firm’s agreement and local professional rules determine when a fee is earned, what notice is required, and how quickly funds should move. These checks protect the distinction between client money and firm revenue.

What is three-way reconciliation?

Three-way reconciliation compares the adjusted trust bank balance, the trust account balance in the firm’s books, and the sum of individual client ledger balances. All three should agree after outstanding items are accounted for. A mismatch calls for investigation and correction; a report alone does not complete the review. LeanLaw makes three-way reconciliation easier by automating it with QuickBooks Online.

What should a firm review when the balances differ?

Start with the bank statement and note deposits or checks that have not cleared. Then compare each bank transaction with the trust register in QuickBooks Online and the related client or matter ledger. Look for a transaction posted to the wrong matter, a duplicate entry, an omitted deposit, or a fee transfer recorded before it was permitted. Document the difference and its correction so the next review has a clear starting point.

The client-ledger total matters because a bank balance can appear correct while money is attributed to the wrong client. A firm should be able to explain both the total it holds and each client’s portion. The trust account reconciliation guide walks through the comparison in more detail.

What are common trust accounting mistakes?

While client trusts may seem pretty straightforward, keeping track of the deposits, withdrawals, any interest earned (if applicable) and all reporting can become pretty complicated, particularly for firms who handle larger amounts of money or have lots of clients.

And whether you work for a large legal practice or run your own law firm, it’s important that you have a good grasp on what’s expected of you when handling these client trust assets if you want to stay compliant with the rules and regulations as well as maintain a strong relationship with your clients.

Here’s a snapshot of some of the biggest dos and don’ts when it comes to trust account management:

Dos for Trust Account Management

• Do segregate funds: Keep client funds separate from the law firm’s operating funds by maintaining a dedicated trust account.
• Do maintain accurate records: Keep detailed records of all trust account transactions, including deposits, disbursements, transfers, and accrued interest.
• Do perform regular reconciliations: Reconcile trust account statements with accounting records on a regular basis to ensure accuracy and identify any discrepancies.
• Do follow proper billing procedures: Bill clients accurately and promptly, clearly specifying the services provided and the amounts due from the trust account.
• Do provide periodic statements: Furnish clients with regular accounting statements, detailing the status of their trust funds and any relevant transaction information.
• Do comply with jurisdictional regulations: Stay informed about the specific rules and regulations governing trust account management in your jurisdiction and ensure compliance.
• Do seek professional advice: Consult legal and accounting professionals to understand and address any complexities or uncertainties in trust accounting.

Don’ts for Trust Account Management

• Don’t commingle funds: Avoid mixing client funds with personal or business funds. Often multiple client’s funds can be held in a pooled trust account, but never have those funds mix with the firms. Keeping client funds separate is a fundamental principle of trust account management.
• Don’t use trust funds for unauthorized purposes: Use client funds only for authorized purposes, such as paying expenses directly related to the client’s matter or distributing funds to the client as instructed.
• Don’t overdraw trust accounts: Ensure that trust account balances are sufficient to cover outstanding client obligations and avoid overdrawing the account.
• Don’t neglect record-keeping: Accurate and up-to-date record-keeping is essential. Failure to maintain bank statements and other important trust documents can lead to accounting errors, compliance issues, and potential disciplinary action.
• Don’t delay reconciliations: Promptly reconcile trust account statements to identify any errors, discrepancies, or fraudulent activities. Delayed reconciliations can lead to unresolved issues and potential financial mismanagement.
• Don’t disregard ethical obligations: Uphold your ethical obligations as an attorney, including the duty to act in the best interests of your clients and safeguard their funds.
• Don’t neglect ongoing education: Stay informed about changes in trust accounting regulations, ethical guidelines, and best practices. Continuing education and professional development can help you maintain a high standard of trust account management.
• Following these dos and don’ts can help attorneys and law firms maintain proper trust accounting practices, ensure compliance with regulations, and uphold their professional responsibilities.

What records should a law firm keep?

A trust account needs more than a bank balance. Keep a register of deposits and payments for the account, an individual ledger for each client or matter, bank statements, and records that explain each transaction. The ledger should show the date, amount, purpose, and remaining balance so a reviewer can trace a deposit through to a disbursement or earned-fee transfer.

Keep copies of invoices and authorizations that explain why money left trust. When a transaction is corrected, preserve enough detail to show the original entry and the correction. These records make it possible to compare the trust register and client-ledger total with the bank statement during reconciliation. Follow your jurisdiction’s requirements for record format, retention, and review frequency.

If more than one client shares a pooled account, the firm still needs to know each client’s share at any point. A positive pooled balance does not mean every individual ledger is positive. Review matter balances before a withdrawal so one client’s money is not used for another client’s obligation.

What software helps with trust accounting?

Staying accurate and in compliance with your firm’s trust accounting needs doesn’t have to be difficult if you take the time to evaluate software against the right criteria. Here’s what to look for:

• Software specifically designed for trust accounting — not a general ledger tool retrofitted for law firms.
• Support for trust account management, including deposits, three-way reconciliation, disbursements, and transfers.
• Features for trust reconciliation and accurate tracking of trust fund balances.
• Compliance (or the ability to be customized to comply) with trust accounting regulations specific to your jurisdiction.
• Safeguards that help prevent common trust accounting errors and fund commingling.
• Reporting built for trust accounting compliance, not generic financial reports.
• Seamless integration with your existing accounting systems, such as QuickBooks Online.
• Compatibility with your operating systems, and clarity on whether it’s cloud-based or on-premises.
• Robust security measures — user access controls and data encryption — to protect sensitive client information.
• Responsive customer support and training resources to help your staff stay current with trust accounting requirements.

Thoroughly researching and evaluating software against these criteria will help you find the trust accounting software that best aligns with your firm’s specific requirements.
