Trust accounting rules are one of the few areas of practice management where a paperwork mistake can turn into a bar complaint, not just an awkward client conversation. Most of the rules aren’t complicated in principle — the difficulty is usually in the discipline of following them consistently, month after month, across every client matter. Here’s a plain-language look at the basics every small firm should have in place.
What Makes Trust Funds Different
Money a client pays you for future work — a retainer, a settlement awaiting disbursement, an advance on costs — isn’t yours yet. It belongs to the client (or a third party) until it’s actually earned or spent on their behalf. That’s why it can’t sit in the same account as your firm’s operating funds: a trust account holds client money separately, precisely so it’s never at risk of being used for the firm’s own expenses, even temporarily.
The Rule That Matters Most: Never Commingle
Commingling — mixing client funds with firm funds, even briefly or unintentionally — is the single most common way attorneys run into trouble with trust accounting. It doesn’t have to be intentional to be a violation; a deposit that lands in the wrong account, or a fee withdrawn before it’s actually earned, can create a problem even when no one meant any harm. The safest practice is treating the separation as absolute, with no exceptions for convenience.
Three-Way Reconciliation, Every Month
Most jurisdictions expect regular reconciliation between three things: the trust account’s bank statement, the firm’s own trust ledger, and the individual ledger for each client whose funds are in the account. If all three don’t match, something is wrong — a fee taken too early, a deposit recorded to the wrong client, a bank fee that quietly ate into someone’s balance. Doing this monthly, rather than only when a bar audit prompts it, is what catches small errors before they become bigger problems.
Common Ways Firms Get Into Trouble
A few patterns show up again and again in bar disciplinary cases: withdrawing a fee before the work is actually completed, letting a client’s balance go negative because a cost was paid out of the wrong ledger, and simply losing track of whose money is whose when multiple matters are open at once. None of these usually start as intentional wrongdoing — they start as small tracking gaps that compound over time.
Where Payment Processing Fits In
Accepting card payments for retainers adds another layer to get right, since card processing fees and chargebacks can themselves create commingling issues if the processor isn’t built for trust accounts. IOLTA-compliant payment processors are designed specifically to keep those fees from touching client funds, which is one of the reasons many firms route retainer and trust payments through a dedicated legal payments provider rather than a general-purpose payment processor.
The Bottom Line
Trust accounting problems rarely start with bad intentions — they start with a process that depends on memory instead of a consistent system. Keeping funds separated by default, reconciling on a fixed schedule, and using tools built for trust compliance rather than general bookkeeping goes a long way toward keeping a firm out of trouble.
