IOLTA three-way reconciliation

Updated October 16, 2026

A three-way reconciliation compares three balances for a client trust account as of the same date: the adjusted bank statement balance, the trust balance in the firm's books, and the total of all individual client ledgers. When the three agree, the firm can show both that the money is there and that it knows whose money it is. Required frequency, format, and retention are set by each jurisdiction.

Who this is for

Firms that reconcile the bank statement but never compare client ledgers, attorneys asked for trust records, bookkeepers taking over an account with no reconciliation history, and practices formalizing procedures before adding staff.

What the reconciliation needs to handle

The adjusted bank balance, the book trust balance after posting, the sum of client ledgers with no negative individual balance, a dated report showing all three and any reconciling items, investigation of differences back to source documents, and a fixed cadence with a named preparer and reviewer.

Questions before hiring

Will you perform a full three-way reconciliation rather than only a bank reconciliation? What report will I receive? How are reconciling items documented? Who reviews it? Can you rebuild client ledgers if history is incomplete?

Frequently asked questions

Why is it called three-way?

Because three separate balances are compared: adjusted bank, book balance, and the total of client ledgers. A two-way bank reconciliation alone does not show whether client-level records agree.

How often is a three-way reconciliation required?

Many jurisdictions expect it at least monthly, but frequency and documentation requirements vary. Check your state bar's trust accounting rules or ethics guidance.

What if the three balances do not match?

The difference is traced to source records to find the cause. Because unresolved differences in client funds can carry professional-responsibility implications, many firms involve bar ethics resources or counsel while records are corrected.

Can software do this automatically?

Practice-management and accounting tools can generate the report, but the data still has to be entered correctly and the result still has to be reviewed and retained.
