The Trust Account Mistakes That Get Small Law Firms in Trouble

If you ask attorneys to name the highest-stakes administrative task at their firm, surprisingly few will say "managing the trust account." But trust account violations are consistently among the leading causes of bar discipline across the country, and small firms are disproportionately represented. Not because small firm attorneys are less ethical — but because they're more likely to be doing the bookkeeping themselves, often without dedicated systems or staff.

Here are the most common ways small firms get into trust account trouble, and how to avoid them.

Mistake 1: Commingling firm funds and client funds. The basic rule of trust accounting is that client money and firm money don't mix. Retainers, settlement proceeds, advance fees that haven't been earned yet — all go into the trust account. Once funds are earned (after the work is done and properly documented), they're moved to the operating account. Where firms get in trouble is when those lines blur: paying firm expenses out of trust, depositing earned fees into trust, leaving earned funds sitting in trust too long, or using one client's funds to cover another's matter while waiting for a deposit to clear.

Commingling violations are taken seriously by bar associations even when no one was actually harmed. The mere act of mixing is the violation.

Mistake 2: Not reconciling the trust account every month. Every state requires regular trust account reconciliation. Most require monthly. This means three numbers have to match: the bank statement, the firm's internal trust ledger (showing all transactions), and the sum of all individual client ledgers (showing what each client's balance should be). When those three numbers don't match — even by a few dollars — something is wrong and it needs to be tracked down immediately.

Firms that skip reconciliation, do it sporadically, or check only the bank balance without comparing it to individual client ledgers often discover problems months or years later, when small errors have compounded.

Mistake 3: Not maintaining individual client ledgers. A trust account that just shows total deposits and withdrawals isn't enough. Every client whose money sits in the account needs their own ledger showing what they put in, what's been earned out, and what their current balance is. Without individual ledgers, you can't actually answer the question "how much of this account belongs to this specific client?" — and bar auditors will ask.

Mistake 4: Moving earned fees out of trust too slowly — or too quickly. This is a balancing act. Earned fees should not stay in the trust account indefinitely once they've been earned; that's a form of commingling because earned money belongs to the firm, not to clients. But fees also shouldn't be moved out of trust before they're actually earned. The cleanest practice is to send the client a bill or notice when fees are earned, then transfer those funds to the operating account in a documented step.

Mistake 5: Using the trust account as a parking spot. Some firms deposit checks into trust because they're "not sure" yet whether the money has been earned or whether it might need to be refunded. This is a problem. The trust account is for funds that belong to clients or third parties — not a holding place for ambiguous money. Decide what category funds belong in before depositing them.

Mistake 6: Bank fees and interest handling. Most states use IOLTA (Interest on Lawyers' Trust Accounts) programs, where interest earned on pooled client funds goes to fund legal aid. Bank fees on IOLTA accounts have specific handling rules — they generally can't be paid out of client funds. Setting up the account correctly with the bank, and ensuring fees and interest are processed properly, prevents accidental violations.

Mistake 7: Three-way reconciliation gaps. Even firms that reconcile monthly sometimes do it incorrectly. The correct process is a three-way reconciliation: bank statement balance, trust ledger balance, and total of all client subledger balances. All three numbers must be identical. Many firms check only two of the three, miss small discrepancies, and have problems multiply over time.

Mistake 8: Inadequate documentation. For every deposit into trust, you should be able to show what it was for, which client it belongs to, and when. For every withdrawal, you should be able to show what was earned, what work was performed, and when the client was notified. "I remember what that was for" is not documentation. Audit trails matter, and good documentation is your best protection if questions ever arise.

Mistake 9: Treating the bookkeeper as a substitute for understanding the rules. Hiring a bookkeeper or using practice management software with trust accounting features is smart. Assuming they'll catch every issue without you understanding the rules yourself is not. The attorney is responsible for the trust account, full stop. Even when someone else manages the day-to-day, the lawyer needs to understand what's supposed to happen and review the work regularly.

Mistake 10: Not having clear written procedures. Most small firms operate trust accounting based on whatever the attorney remembers to do. That works until someone is on vacation, sick, or leaves the firm — and then small inconsistencies become bigger problems. A short written procedures document covering how funds are deposited, how earned fees are transferred, who reconciles and when, and what to do if a discrepancy is found is one of the most underrated risk-management tools a small firm can have.

A practical place to start. If you've been running your trust account by feel rather than by process, the most useful thing you can do right now is take an honest look at where things stand. Pull the last three months of trust statements. Reconcile them properly (three-way). Look at every client whose funds are in trust and confirm the balance you'd report matches the balance the ledger shows. If anything looks off, get help addressing it before it gets bigger.

Trust accounting isn't glamorous. It also isn't optional. Firms that take it seriously sleep better, audit better, and don't end up explaining themselves to disciplinary counsel.
