How Long Does a Law Firm Have to Keep Trust Account Records?

Trust account records have their own retention period, set by your state bar’s trust accounting rule, and it runs separately from the retention period for client files. Five years after the termination of the representation is the most common requirement, but several states set it longer, and a few tie the clock to the last transaction on the account rather than the end of the matter. Read your rule. This is one of the few compliance questions where the general answer is genuinely unsafe.

What trips firms up is less the duration than the scope: the rule covers more than the bank statements.

Which records does the rule actually cover?

Trust accounting rules generally name a set of records, not a folder. Expect all of these to be in scope:

• Bank statements and cancelled check images for every trust account, including any separate interest-bearing account held for a single client.
• Deposit slips and deposit detail, showing which client each deposit belonged to.
• Individual client ledgers, showing every receipt, disbursement, and running balance for each client whose funds you held.
• The trust account general ledger, meaning the firm’s own book record of the account.
• Completed reconciliations, usually monthly, usually three-way. In several jurisdictions the reconciliation itself is a required record, so producing the underlying data isn’t sufficient if you never documented the reconciliation.
• Records of every disbursement, including who authorized it and what it was for.
• Signed engagement terms and any fee agreement governing the funds.

The reconciliation requirement is the one firms most often fail on. Doing the reconciliation and keeping the reconciliation are two separate obligations, and only the second one is provable later. Our walkthrough of the three-way reconciliation process covers what a documented reconciliation contains.

Why trust records and client files are different clocks

Client file retention is about the representation. Trust record retention is about the money, and the money has its own timeline.

A matter can close in March with the file eligible for destruction on one schedule, while the trust records for that matter stay live on a different one. Firms that run a single retention policy across everything tend to destroy trust records early, because the client file schedule is the one that gets written down. Our guide to document retention policies covers the client file side; treat trust records as a separate schedule with its own trigger date.

There’s a second wrinkle. If a client’s funds sat in trust for years before disbursement, or if a residual balance is still sitting there, the clock on those records may not have started at all. Dormant balances keep their records alive. Our guide to dormant client funds at year end covers how those balances get resolved.

What has to survive a software change

This is where retention quietly fails, and it’s worth naming before it happens to you.

When a firm changes billing or practice management software, the matters usually migrate. The trust history often doesn’t. Individual client ledgers built inside a vendor’s system are that vendor’s records, and export formats vary from complete to decorative. A firm that switched systems three years ago and can no longer produce a client ledger from four years ago has a retention problem that no policy document will fix.

Two things make this survivable:

Keep the general ledger somewhere durable and portable. If the trust bank account, the trust liability, and the per-client detail live in your accounting system rather than inside a billing tool, the record survives a change of billing tool. This is a practical argument for keeping the ledger in QuickBooks Online rather than inside a practice management platform: your accountant already has access, the file is yours, and switching the layer above it doesn’t touch the history.

Archive the reconciliations as documents, not as software state. A saved PDF of a completed monthly reconciliation is readable in ten years by anyone. A reconciliation that exists only as a screen inside a subscription you cancelled is not. Our guide to securely backing up trust accounting records covers the mechanics.

What to do this month

Three things, none of which require a project:

1. Find your state’s trust accounting rule and write down the retention period and its trigger date. Termination of representation and last transaction on the account are different triggers and produce different destruction dates.
2. Check that you can produce a completed reconciliation for a month two years ago. If you can’t, the gap is already there and it’s easier to document now than during an examination.
3. Confirm your trust history would survive a software change. If the individual client ledgers only exist inside one vendor’s product, that’s a retention exposure regardless of what your policy says.

Frequently asked questions

How long must a law firm keep trust account records? It’s set by your state bar’s trust accounting rule. Five years after the end of the representation is the most common period, and several states require longer. Confirm the period and the trigger date in your own rule rather than relying on a general answer.

Is the retention period for trust records the same as for client files? No. They’re separate obligations with separate clocks, and firms that run one policy for both tend to destroy trust records too early.

Do I have to keep the monthly reconciliations themselves? In many jurisdictions, yes. Performing the reconciliation and retaining documentation of it are two separate requirements.

Does QuickBooks Online keep my trust records for me? It holds the ledger and the transaction history as long as you maintain the subscription and the file. Cancelled check images, deposit detail, and archived reconciliations should be stored deliberately rather than assumed.

What happens to trust records when a firm dissolves? The retention obligation survives the firm. Most jurisdictions require a designated custodian for the records, and the obligation runs for the full retention period regardless of whether the firm still exists.
