Law Firm Trust Account Audit Preparation: A Checklist of What State Bar Auditors Look For

A law firm trust account audit is stressful even when your records are clean, and it can be frightening when your records are not complete. Understandably, most firms scramble to clean up practices when an audit notice arrives.

Trust compliance, however, isn’t a one-time project. It’s a continuous practice built on accurate records, timely reconciliations, and predictable workflows. This checklist distills what state bar auditors typically examine and how to stay audit-ready all year long.

What Triggers a Law Firm Trust Account Audit

State bars conduct audits for many reasons, most of which have nothing to do with wrongdoing.

• Random selection. Many states audit a certain percentage of law firms annually (see New Jersey’s program). Your state bar association should offer guidance on how selection works and what the random audit process looks like.
• Overdraft notifications. Banks are required to report any overdraft on an IOLTA account. Even small overdrafts must be reported.
• Client complaints. If a client complains about fees, holding settlement funds, or anything related to finances, it can trigger an audit. A pattern of complaints is even more likely to result in an audit.
• Late or missing reporting. Most states require some kind of certification related to trust accounting, and noncompliance can trigger an audit. Some states, like California, require detailed reporting (see this article for an overview).

The Records Auditors Ask For

Regardless of the trigger, auditors look for the same core records and practices. The foundational trust accounting requirements are similar in every state, although there can be important differences in the details. In general, auditors are looking at the following.

• Individual client trust ledgers. All trust activity for each client/matter. There are state-specific requirements for what must be tracked (typically date, check number, payor/payee, purpose, credit/debit, and running balance).
• Firm trust account ledger. Trust activity at the firm level. Usually has similar requirements to the trust ledger.
• Bank statements. These show how money moves in and out of the trust and operating account(s).
• Payment records. Documentation of all money deposited and paid, including canceled checks, electronic payment records, deposit records, etc.
• Three-way reconciliations. Conduct three-way reconciliation (bank balance, check register, and client ledgers) monthly and keep documentation of each reconciliation.
• Required communications. This includes fee agreements and required trust accounting notifications in engagement letters, invoices, accountings, etc.

Make sure to retain records for the required period. Most states require you to retain trust accounting records for 5-7 years (Georgia, for example, requires retention for 6 years.)

Four Practices Auditors Test

Beyond documentation, auditors evaluate whether your trust accounting behaviors follow required standards. The following are four universal trust accounting practices; your state may have additional required practices.

1. Monthly three-way reconciliation

It is critical to conduct a three-way reconciliation every month. Every penny must be accounted for. You must compare:

• The bank statement against the trust ledger.
• The bank statement against each client’s trust ledger.

Because trust errors tend to snowball, early detection is key. Many firms choose to reconcile right before creating the monthly billing statements.

2. No negative balances

Trust accounts should never be overdrawn, and banks are required to report any negative balance to the state bar association. Your state may also require attorneys to notify the bar directly. Some firms try to compensate for the risk of overdraft by adding firm funds to the trust account, but this is prohibited, because it constitutes commingling. Depending on your state, you may be allowed to deposit a nominal sum to cover anticipated banking fees, but check the rules to make sure you do not exceed any state limits.

3. No commingling

The firm’s money and your client’s money must never be commingled. This rule is typically incredibly strict: in Oregon, a lawyer cannot even replace funds stolen from the trust account without getting the client’s permission. Common commingling mistakes include:

• Moving money to the operations account before it is earned. Be especially cautious with flat fees, retainers, and advanced fees. Your state may have rules about when they are considered earned.
• Not moving money to the operations account after it is earned. Once fees are earned, they belong to the firm, and leaving them in the trust account (beyond a reasonable time) is commingling. Sending client statements monthly and moving money promptly can help you avoid this problem.
• Problems with electronic payments. Using a general-purpose payment processor can cause commingling problems, like a charge-back applied to the trust account instead of the operations account. Make sure to use a compliant processor.

4. Timely disbursements

When you receive money on behalf of a client (like a settlement check) or a third party, you must disburse it in a timely fashion: in a week, not a month. Check your state’s rules to understand detailed timing obligations.

The Continuous-Readiness Checklist

Staying audit-ready requires a predictable cadence of trust accounting tasks. A monthly or quarterly rhythm can keep your records clean whenever an auditor asks for them.

Monthly

• Complete a three-way reconciliation.
• Review all client ledgers for negative or unusual balances.
• Verify deposits match source documentation.
• Confirm disbursements have proper authorization.

Quarterly

• Audit your own trust records internally.
• Review inactive matters with trust balances.
• Validate retention compliance.

Annually

• Confirm compliance with your jurisdiction’s trust accounting certification.
• Audit template-based communications, like engagement letters, for compliance.
• Review your written policies to make sure they are compliant and offer refresher training for attorneys and professional staff.
