Law firms hold other people’s money constantly: retainers not yet earned, settlements not yet disbursed, filing fees not yet paid. The accounting discipline that keeps that money safe, and keeps lawyers licensed, is trust accounting, and the account most of it lives in is an IOLTA. This guide explains both, shows the reconciliation routine bar auditors expect, and lays out how to choose a trust accounting system.
What Is Trust Accounting?
Trust accounting is the tracking and safeguarding of money a law firm holds for clients and third parties. It rests on one principle with teeth: the money isn’t the firm’s. From that principle follow the operating rules every state bar enforces: client funds stay in a separate trust account, never mixed with firm funds; every dollar is tracked to a specific client and matter on its own ledger; fees move out of trust only when earned and billed; and the books must prove, at any moment, exactly whose money the account holds. A trust accounting error isn’t a bookkeeping problem, it’s a license problem: discipline for trust violations ranges up to disbarment, and intent is not a defense.
What Is an IOLTA Account?
An IOLTA account (Interest on Lawyers’ Trust Accounts) is the standard client trust account American law firms use: a pooled, interest-bearing account holding funds that are too small or too short-term to earn net interest for any individual client. The interest goes to the state’s IOLTA program to fund legal aid; the lawyer never keeps it, and neither does the client. Every state and DC runs an IOLTA program, and most require participation.
An IOLTA trust account is the same thing said twice: IOLTA is a type of trust account. When client funds are large enough or held long enough to earn meaningful net interest, they go instead into a separate interest-bearing trust account where the interest belongs to that client. That decision (pooled IOLTA versus separate account) is the lawyer’s to make in the client’s interest under state rules.
How Do IOLTA Accounts Work?
- Client money arrives (a retainer, a settlement) and is deposited into the pooled IOLTA promptly. It is recorded on that client and matter’s individual ledger the same day.
- The bank sees one balance; the firm’s books see many. The sum of every client ledger must always equal the account, and no client’s ledger may ever go negative, because a negative ledger means another client’s money is being spent.
- Fees earned and billed transfer from IOLTA to the firm’s operating account, and only then become revenue. Unearned funds go back to the client when the matter ends.
- The bank remits the account’s interest to the state IOLTA program automatically. The firm’s only involvement is opening the account correctly at an approved institution.
- Each month, the firm reconciles three ways and archives the report.
Three-Way Reconciliation: The Routine That Keeps You Compliant
Three-way reconciliation is the heart of trust compliance, and the first thing a bar auditor asks for. Three numbers must agree:
- The bank statement balance, adjusted for deposits and checks that haven’t cleared.
- The firm’s trust ledger (checkbook) balance from its books.
- The sum of all individual client ledger balances.
If any pair disagrees, something is wrong: a transaction posted to the wrong matter, an uncleared item gone stale, a disbursement that overdrew a client ledger. Most states expect the reconciliation monthly; every firm should archive each report, because being unable to produce records is itself a violation. And never force a balance with an adjusting entry: find the error, fix the error, document the fix.
“The auditor’s question is never “does the bank account balance?” It’s “can you show me whose money this is?””

What Is the Best Trust Accounting System for Law Firms?
The best trust accounting system is one where compliance is enforced by the software, not by hoping everyone remembers the rules. Generic accounting tools can’t do this: they have no client ledgers inside a bank account, no concept of a matter, and no three-way reconciliation report. Evaluate on:
- Client and matter ledgers native to every trust transaction, with automatic prevention of negative client balances
- One-step three-way reconciliation with printable, archivable reports
- Integration with billing, so earned fees move from trust to operating in one recorded step, and with the firm’s general ledger
- Check printing, electronic disbursements, and bank feeds with a full audit trail (who, when, which matter)
- Safeguards for the details that trip firms up: service-charge handling, stale uncleared items, credit card retainers routed so fees never touch trust
- Reports a bar auditor can use on arrival: client balance listings, transaction histories, reconciliation archives
