5 Trust Accounting Rules That Keep Law Firms Out of Trouble With the Bar
Sam's List Editorial | 2026-06-27
For a law firm, trust accounting is the one area where a bookkeeping error can become an ethics problem. Client funds held in trust belong to the client, and state bars treat mistakes seriously even when they are honest. Getting law firm trust accounting right is less about sophistication and more about discipline around a handful of rules. Here are five that keep firms out of trouble, and what each one prevents.
These are general principles. Specific requirements vary by state bar, so always check your jurisdiction's rules. The point is to understand the shape of the obligations so you can build a process that meets them.
1. Never Commingle Trust and Operating Funds
Client funds belong in a separate trust account, never mixed with the firm's operating money. Commingling is one of the fastest ways to draw a bar complaint, because it blurs the line between the client's money and yours. What it prevents: the appearance, or reality, of using client funds to run your firm.
2. Reconcile Three Ways, Every Month
Trust accounting requires that three numbers always agree: the trust bank balance, your book balance, and the total of every individual client's ledger. A three-way reconciliation done monthly catches errors before they compound. What it prevents: a small discrepancy quietly growing into a shortfall you cannot explain to the bar.
3. Keep a Ledger for Every Client
You must be able to show exactly how much of the trust account belongs to each client at any moment. Individual client ledgers make that possible. What it prevents: the nightmare scenario of knowing the total but not being able to prove whose money is whose.
4. Only Withdraw What Is Earned
Money in trust becomes yours only when it is earned or costs are incurred, and the rules around moving it require care. Withdrawing unearned funds, even temporarily, is a violation. What it prevents: dipping into client money before you have the right to it, which bars treat as a serious breach.
5. Never Let the Trust Account Go Negative
An individual client's balance within the trust account should never go negative, because that means you have spent another client's money. Even a brief overdraft on one client's ledger is a red flag. What it prevents: using one client's funds to cover another's, a classic and serious trust violation.
Why Specialized Bookkeeping Matters Here
Trust accounting is exactly the kind of work where a generalist bookkeeper, however skilled, can create real exposure if they have never handled an IOLTA account. Legal Ease is a Fort Worth Sam's List bookkeeping firm whose focus fits solo and small law practices, the kind of specialist that treats trust compliance as the first priority rather than an afterthought. For an attorney who would rather practice law than reconcile a trust ledger, that specialization reduces real risk. Confirm credentials and fit, and always defer to your state bar's rules.

Frequently Asked Questions
What is the most common trust accounting violation? Commingling, mixing client trust funds with the firm's operating money, is among the most common and most serious. Close behind are failing to reconcile regularly and letting an individual client's ledger balance go negative, which means one client's funds covered another's.
How often should a law firm reconcile its trust account? Monthly is the standard expectation in most jurisdictions, using a three-way reconciliation that matches the bank balance, the book balance, and the sum of all client ledgers. Reconciling monthly catches discrepancies while they are small and easy to fix.
Can a regular bookkeeper handle law firm trust accounting? Only if they genuinely understand IOLTA rules and three-way reconciliation. Many generalists do not, and the risk of a commingling or reconciliation error is high enough that many firms choose a bookkeeper who specializes in legal accounting.
What happens if my trust account is out of compliance? Consequences vary by state bar but can include audits, disciplinary action, and in serious cases suspension. Because the stakes are an attorney's license, trust accounting deserves more rigor than ordinary bookkeeping, which is why specialized help is common.
