8 Trust Accounting Mistakes That Put a Law Firm's License at Risk

8 Trust Accounting Mistakes That Put a Law Firm's License at Risk

You can lose your license over a missed filing deadline. You can also lose it over a $400 bookkeeping error in your trust account.

One of those feels fair. The other one ends careers anyway — and it is the more common path. The most dangerous law firm trust accounting mistakes are almost never theft. They are sloppiness, a misunderstood rule, or a reconciliation nobody ran for six months.

Here is the part that should get your attention: the standard your state bar judges you against is not "did you mean well." Under ABA Model Rule 1.15, on which most states base their own version, client funds must be held separate from the lawyer's own property, and you must keep complete records and account for the money on request. Intent is not a defense. The records are.

These are the eight attorney trust account errors that draw bar complaints and audits most often — and the IOLTA compliance bookkeeping habits that keep you out of the disciplinary docket.

The law firm trust accounting mistakes that draw bar complaints, ranked by how often they bite

1. Commingling earned and unearned money in one account

This is the single fastest way to draw a bar complaint, and the line has to be bright.

Unearned funds — retainers, settlement proceeds, advance fees you have not yet billed against — belong in trust. Money you have actually earned belongs in your operating account. The moment those two live in the same account, you have a problem, even if every dollar is technically present.

Why? Because Rule 1.15 requires client property to be kept separate from your own. A blended account fails that test on its face. The bar does not have to prove you spent a client's money. They only have to prove you didn't keep it separate.

2. Paying operating expenses out of the IOLTA account

Your rent is due, the operating account is light, and there is plenty sitting in trust. So you cover the rent from the IOLTA account and move it back on Friday.

That is a violation in every state — full stop. It does not matter that the money was nominally yours to earn eventually. It does not matter that you paid it back. The day you used client trust money for a firm expense, you used client funds for something other than the client's matter. Repayment doesn't undo it; it just means the audit finds a round trip instead of a hole.

There is one narrow, legitimate exception: under Rule 1.15(b), you may keep a small amount of your own money in the trust account solely to cover bank service charges. That is the only firm money allowed in there.

3. Skipping the three-way reconciliation

Most firms reconcile their trust account the way they reconcile a personal checkbook — bank statement against the register. That catches about a third of the problems.

A proper trust reconciliation is three-way. You match the bank balance, your internal trust ledger, and the sum of every individual client's ledger balance. All three have to agree to the penny. Most states require this monthly, and it is the single procedure that surfaces nearly every error on this list before the bar does.

If you have never run a three-way reconciliation, that is not a small gap. That is the control that proves you are compliant — and its absence is what an examiner looks for first.

4. Letting a client's trust balance go negative

A negative client trust balance is not a rounding quirk. It means you disbursed more for that client than you were holding for them — which means you spent another client's money to do it.

This is the violation firms almost never catch on their own, because the master account still shows a positive balance. Everything looks fine at the bank. It is only when you total the individual client ledgers that the gap appears. Most firms find out during an audit, which is the worst possible time.

The three-way reconciliation in mistake #3 is exactly what catches this. Run monthly, a negative client ledger gets flagged in week one instead of year three.

5. Leaving earned fees sitting in trust too long

Overcorrecting is also a violation. Once a fee is genuinely earned, that money is no longer the client's — it is yours, and parking it in trust means your operating funds are commingled in the client account. Same rule, opposite direction.

The fix is a schedule. When you bill against a retainer and the work is done, sweep the earned portion into your operating account on a defined cadence. "I'll get to it" is not a cadence. A monthly fee sweep, documented, is.

6. Disbursing against deposits that haven't cleared

A settlement check hits the trust account on Monday. The client wants their share Tuesday. You cut the check.

Then the deposit bounces, or a hold extends. Now you have disbursed money you never actually had — and you have covered it, again, with other clients' funds. The rule of thumb experienced firms follow: do not disburse against a trust deposit until it has truly cleared, not merely posted as available. The two are not the same, and the difference is your license.

7. Keeping records that wouldn't survive a bar audit

Rule 1.15 requires you to keep complete records of trust property and to render a full accounting on request. "On request" includes a request from a disciplinary investigator.

That means individual ledgers per client, dated deposits and disbursements tied to a specific matter, retained bank statements and canceled checks, and monthly reconciliation reports you can actually produce. Most states require you to keep these for five to seven years. A shoebox of statements and a mental model of who is owed what is not a record. It is the absence of one.

8. Treating trust accounting as a part-time afterthought

The through-line of the first seven mistakes is the same: trust accounting got handled in the cracks between billable work, by whoever had a free hour. That is how bright lines blur.

Trust accounting is a specialized discipline with its own rules, its own reconciliation method, and consequences that land on your bar card rather than your bottom line. It is not a task for a generalist bookkeeper who also does your invoicing — it is the thing that should be done by someone who does only this, every month, the same way.
