What is three-way reconciliation for a law firm trust account?

Three-way reconciliation is the process of verifying that three separate records all produce the same ending balance at month-end. Those three records are the bank statement for the trust account, the trust account check register (your book balance), and the combined total of every individual client ledger you maintain within that account. If all three match, you know client funds are accounted for. If they don’t, something is wrong and needs to be resolved before you move on.

The trust account check register is your internal record of every deposit and disbursement flowing through the account. It works like any checkbook register. You record what came in, what went out, and what the running balance should be. The bank statement shows what the bank actually processed. Reconciling these two catches timing differences like outstanding checks, bank fees, or transactions you missed recording. This is a normal bank reconciliation that every business should do.

The third piece is what makes it specific to law firms. Because your trust account holds money belonging to multiple clients in a single bank account, you also maintain a separate ledger for each client showing their individual balance. The sum of every client ledger should equal the total trust account balance. If Client A has $5,000, Client B has $12,000, and Client C has $3,000, your trust account balance should be exactly $20,000. No more, no less.

When the three numbers don’t match, you have a problem that must be investigated immediately. Common causes include recording a deposit to the wrong client ledger, missing a disbursement entry, bank errors, or timing issues with transfers. Less common but far more serious causes involve commingling of funds or unauthorized disbursements. Whatever the reason, the discrepancy has to be identified and corrected right away.

This is not optional bookkeeping hygiene. The Virginia State Bar requires attorneys to safeguard client funds held in trust, and three-way reconciliation is the standard method for demonstrating that those funds are properly managed. Failure to maintain accurate trust account records can result in disciplinary action, including suspension or disbarment. The reconciliation should be performed monthly and the documentation retained. If the Bar ever audits your trust account, they will want to see a clear paper trail showing the reconciliation was done consistently and that any discrepancies were resolved promptly.

From a practical standpoint, the reconciliation is straightforward if your records are maintained properly throughout the month. Every deposit gets recorded to the correct client ledger on the day it happens. Every disbursement gets posted accurately. If you let entries pile up or skip weeks of record-keeping, the month-end reconciliation becomes a painful exercise in detective work instead of a simple confirmation that everything ties out.

Many law firms in the DMV area work with bookkeepers in Fairfax who understand trust accounting requirements specifically because getting this wrong carries real consequences. A general bookkeeper who doesn’t know the difference between an operating account and an IOLTA account can create compliance problems without realizing it.

If you run a firm and your trust accounting feels disorganized or you’re not confident the three-way reconciliation is being done correctly each month, that’s a risk worth addressing sooner rather than later. Professional services bookkeeping for law firms requires someone who understands both the accounting mechanics and the ethical obligations that come with handling other people’s money. The reconciliation itself isn’t complicated. What matters is that it gets done every month, done right, and documented so you can prove it.
