Three-Way Reconciliation Explained: What Every Attorney Needs to Know

What Is Three-Way Reconciliation?

Three-way reconciliation is the process of verifying that three separate numbers always agree:

1. Your bank statement balance — what the bank shows, adjusted for outstanding items
2. Your book balance (check register) — your running total of all deposits and disbursements
3. The sum of all client sub-ledger balances — what you owe each client individually

All three must match every month. If they don't, you have a discrepancy that must be found and corrected before you can certify the reconciliation.

Why Three Numbers, Not Two?

Most bank reconciliations only check two things: your records against the bank. Trust accounting adds a third check — the individual client ledgers — because trust funds belong to specific clients. It's not enough for the total to balance. Every client's portion must be traceable and accurate.

This matters especially in audits. Bar examiners will pick a client matter at random and trace every transaction from opening to close. If your sub-ledgers don't reconcile to the bank, that's an immediate finding.

Step-by-Step: How It Works

Step 1 — Reconcile the bank statement

Start with your bank statement ending balance. Add deposits in transit (deposits you've recorded but the bank hasn't posted yet). Subtract outstanding checks (checks you've issued that haven't cleared). The result is your adjusted bank balance.

Step 2 — Reconcile your book balance

Start with your check register (ledger) balance. Add any bank credits not yet in your records (such as interest, though interest should be swept out of IOLTA accounts immediately). Subtract any bank charges not yet recorded. The result is your adjusted book balance.

Step 3 — Sum all client ledger balances

Add up the current balance for every open client matter. This is the client ledger total.

Step 4 — Verify all three match

Adjusted bank balance = Adjusted book balance = Client ledger total.

If any two of these don't match, there's an error somewhere. Common causes include voided checks not reflected in the ledger, transposed numbers, or a disbursement posted to the wrong matter.

How Often Is Reconciliation Required?

Most state bar rules require monthly reconciliation. Many require it to be completed within 30 days of the statement close date. Some states require the reconciliation to be signed and retained for at least five years. Check your specific state's rules — IOLTATrusts includes a built-in guide for all 50 states.
