Three-way trust reconciliation: a plain-English guide for law firm owners
By Douglas Small · October 2026 · About a nine-minute read
Somewhere this month a managing partner is opening a letter from the bar about the firm’s trust account. Almost none of the lawyers who get that letter stole anything. Most of them just never reconciled the account the way their rules required, and by the time anyone looked, the numbers had drifted far enough that nobody could explain them. “It was like that when I got here” isn’t a defense the bar has ever found persuasive.
A three-way reconciliation is the routine that keeps that letter from showing up. When the books are kept properly it takes about an hour a month. I don’t know of cheaper insurance.
Three numbers that have to agree
A normal bank reconciliation compares two numbers: what the bank says you have and what your books say you have. A trust account has a third number, and it’s the one that matters most: what you owe each client.
So a three-way reconciliation checks that three figures agree on the same date:
- The bank balance, adjusted for deposits in transit and checks that haven’t cleared.
- The trust ledger balance, meaning the running total in your accounting system for the trust account as a whole.
- The sum of the individual client ledgers, meaning every client’s balance added together.
If all three match, every dollar in the account belongs to a client you can name, and the account holds exactly what it should. If any two disagree, something’s wrong, and which two disagree tells you where to start looking.
Why the third number is the one that matters
The bank and your books can agree perfectly while the account is still out of compliance. Say one client’s ledger shows a negative $4,000 because a settlement check went out before the funds cleared. Another client’s $4,000 is quietly covering it. The account total is right, the bank agrees, and you’ve still used one client’s money to pay another client’s expenses, which is the exact thing trust rules exist to prevent. “But it balanced” doesn’t help you here.
Only the client ledger total exposes that. That’s why a two-way reconciliation isn’t enough, and why most state bars want the third leg.
What your bar expects
Most of the firms we work with are in New York, Washington, D.C., New Jersey and Connecticut, so here’s what those four rules actually say. New Jersey and Connecticut put a schedule in the rule. New York and D.C. don’t, and I’d be careful about reading much comfort into that.
| New York | Washington, D.C. | New Jersey | Connecticut | |
|---|---|---|---|---|
| Where it lives | Rule 1.15(d), 22 NYCRR Part 1200 | Rule 1.15(a) | Court Rule 1:21-6(c) | Rule 1.15(j), Practice Book |
| How often | No interval written into the rule. Courts discipline lawyers who don’t reconcile anyway, and the Lawyers’ Fund calls monthly “good business practice.” | No interval written into the rule. The comment says to review trust practices “at reasonable intervals.” | At least monthly. | Reconciliation at least quarterly, plus a trial balance of the client ledgers every month. The official commentary calls monthly “the preferred practice.” |
| Three legs required? | Not spelled out. The New York City Bar proposed in May 2026 a three-way report at least every 60 days; it hasn’t been adopted as of this writing. | Not spelled out. | Yes, and then some: the journal cash balance, the checkbook balance, the bank statement and the client ledger balances all have to be reconciled, and a trial balance of the client ledgers has to agree to a control figure. | Yes in practice: the commentary’s method compares the client-ledger trial balance, a control balance from the journals and the bank statement. |
| Keep records for | Seven years after the event recorded. | Five years after the representation ends. | Seven years after the event recorded. | Seven years after the representation ends. |
| Worth knowing | Lawyers in the First and Second Departments certify their Rule 1.15 compliance at every biennial registration. Banks report bounced escrow checks to the grievance committees. | Approved banks report trust overdrafts to Disciplinary Counsel. | The Office of Attorney Ethics runs random audits. Only a New Jersey-admitted lawyer may sign a trust check or authorize a transfer. No ATM or cash withdrawals, and no overdraft protection on the account. | The Statewide Grievance Committee runs random trust account audits. |
Here’s what I take from the table. Where a state writes a schedule into the rule, it’s monthly or quarterly. Where it doesn’t, New York and D.C., the courts discipline lawyers for failing to reconcile under the general recordkeeping and fitness rules instead. The duty is still there; there’s just no date attached. I went through the reported New York cases from the last two years where a lawyer “failed to reconcile.” Every one ended in censure, suspension or disbarment, and not one of them stopped to ask how often the lawyer was supposed to have done it.
So for all four jurisdictions I give the same advice: reconcile monthly, keep the paper, and you’ll never have to argue about what the rule technically requires.
A few states have gone further. If you practice elsewhere, or hold funds for clients who do, these are the ones that stand out:
- Massachusetts requires a three-way reconciliation report at least every 60 days, treats bank fees as their own client ledger, and says flatly that no individual client balance may be negative at any time.
- Illinois wrote the phrase “three-way reconciliation” into the rule itself in 2023, at least quarterly, with the records kept seven years.
- North Carolina wants a bank reconciliation every month and a three-way reconciliation every quarter, which the lawyer has to review, sign and date, then keep for six years.
- Florida requires monthly reconciliations plus an annual list of every client’s unspent balance, and every lawyer files a trust accounting certificate with the Bar each summer. Miss the certificate and you can’t practice until you file it.
- California built a whole program around it: annual trust account registration and a self-assessment under the Client Trust Account Protection Program, monthly reconciliations of ledger, journal and bank, records kept five years from disbursement, and compliance reviews that started in 2025.
- Virginia and Pennsylvania both require monthly reconciliations. Virginia adds that a lawyer in the firm has to approve each one and explain any discrepancy in writing.
Rules change. This is accurate as of October 2026 and we’ll keep it current, but if your state isn’t listed here, read your own rule before you assume it follows the pattern.
How to do it
This is the routine we run for the firms we serve. It assumes trust transactions get recorded as they happen. That’s the real prerequisite; the rest is arithmetic.
1. Close the month in the trust ledger. Every deposit, disbursement and transfer dated in the month should be posted before you start. Chasing an unposted item in the middle of a reconciliation is how errors creep in.
2. Reconcile the bank statement to the ledger. Tick every cleared item. List deposits in transit and outstanding checks. The adjusted bank balance should equal the ledger balance to the penny. If it doesn’t, stop and find the difference before you go any further. And don’t accept a “reconciled balance” just because the software says so. A transfer can go in and out of the account without ever being recorded against a client in the trust ledger, and the bank reconciliation will look perfect while the client side is wrong.
3. Run the client ledger listing. Every client with a balance, with the total at the bottom. Look for three things: any negative balance, any balance belonging to a closed matter, and any client you don’t recognize. That last one comes up more often than you’d think.
4. Compare the client total to the ledger balance. If they match, the three legs agree. Print or save the three reports together with a one-page summary showing the three numbers and the date, and sign it.
5. Resolve anything that doesn’t agree before you file it. If there’s an unexplained difference, you haven’t reconciled yet. You’ve found out that you need to.
The five problems it catches
Across fifteen-plus law firms and a decade of monthly reconciliations, the same handful of problems account for nearly everything we find. Nobody has to be a crook for any of them to happen. All of them still have to be fixed.
Negative client balances. Money disbursed before it cleared, or a cost paid from trust that should have come from operating. Fix it the same day by transferring from operating, then find out why the disbursement went out early.
Earned fees left in trust. A fee is earned when the invoice goes out and the client’s funds are applied, and it should move to operating promptly. Leaving earned fees in trust commingles your money with your clients’. This matters most at year end: don’t wait until January to transfer fees you earned in December. The IRS will be disappointed in you, and they don’t express disappointment the way your mother does.
Unidentified deposits. A wire arrives with no matter reference. It sits in the account unallocated, the client total falls short of the bank, and the reconciliation fails until someone figures out whose it is. Make it a rule that nothing gets deposited without a matter number, and hold to it even when the sender is a partner’s biggest client.
Bank charges hitting the trust account. Wire fees and monthly service charges are the most common way a client balance goes negative without anyone doing anything wrong. Get your bank to charge every fee to operating. If one slips through anyway, reimburse trust the day you see it.
Stale balances. A few hundred dollars left for a client whose matter closed years ago. Harmless until an auditor asks whose money it is and nobody in the room can answer. Review balances older than twelve months and either refund them or follow your state’s unclaimed property procedure.
What to keep, and for how long
Keep the monthly package together: the bank statement, the reconciliation summary, the outstanding items list and the client ledger listing. Store it somewhere it can’t be edited after the fact. If your state asks for records, they want to see the reconciliation as it was done at the time, not a tidier version put together the week the letter arrived.
Retention runs five to seven years. Some states count from the event recorded, others from the end of the representation. The table above says which, and when in doubt, keep it longer.
When it has already gone wrong
If the three legs have never agreed, or nobody has reconciled the account since the firm opened, the fix is a reconstruction: rebuilding the client ledgers from bank records and matter files back to the last point they balanced. It’s tedious, not complicated, and far better done before the bar asks than after. Think of it as flossing. Nobody enjoys it, and the alternative involves a professional and a bill.
If the reconstruction turns up money that can’t be explained, that’s a different engagement, and one our forensic practice handles. When I was an FBI Agent, I worked a federal case involving a law firm employee who moved two million dollars out of client trust accounts over several years. It was found through exactly this kind of reconciliation, done late. Done monthly, it would have been found in month one.
Frequently asked questions
Does New York actually require a three-way reconciliation?
The rule doesn’t use the word. It requires accurate, contemporaneous records of every deposit and withdrawal and whose money it is, kept for seven years, and the courts have treated a failure to reconcile as a violation of those records rules and of a lawyer’s fitness to practice. A proposal to add an explicit three-way reconciliation every 60 days is pending. Do it monthly and none of that will ever matter to you.
How long does a monthly three-way reconciliation take?
About an hour for a firm with a few dozen active matters, provided trust transactions are posted as they happen. Firms that post everything at month end spend most of that hour finding items, not reconciling them.
Do we need separate trust accounts for each client?
Generally no. One pooled trust account with individual client ledgers satisfies most state rules. Large or long-held sums are sometimes put in a separate interest-bearing account for the client’s benefit; your state rules will say when.
What happens if the three numbers never match?
Treat it as urgent. Stop disbursing from trust except where you can confirm that specific client’s funds are there, and reconstruct the ledgers until they balance. Most differences turn out to be bookkeeping errors, but the account has to be proven clean before you use it normally again.
