Quick answer: A three-way reconciliation confirms that three numbers match at month-end: your adjusted trust bank balance, your trust checkbook (control) balance, and the total of every client’s individual ledger balance. When all three agree, your IOLTA is in balance. When they don’t, client money is misstated — and in New York that is a bar-discipline problem, not just a bookkeeping one.
What a three-way trust reconciliation actually is
Every attorney who holds client or third-party money in a trust or IOLTA account has to be able to prove, at any moment, exactly how much of that pooled balance belongs to each client. A three-way reconciliation is how you prove it. It ties together three independent records that should always equal one another:
- The adjusted bank balance — the trust account’s bank statement balance, adjusted for outstanding checks and deposits in transit.
- The book (control) balance — your trust checkbook or general trust ledger running balance.
- The sum of client ledgers — the total of every individual client’s trust ledger balance added together.
Two-way reconciliation (bank to checkbook) is what most bookkeepers do, and it is not enough. It can be perfectly balanced while an individual client’s ledger is negative — meaning you spent one client’s money on another’s matter. The third leg, the client-ledger total, is the whole point.
Why your state bar will not accept a two-way reconciliation
Nearly every U.S. jurisdiction bases its trust-account duties on ABA Model Rule 1.15, which requires a lawyer to hold client funds separately, keep complete records of each receipt and disbursement, maintain an individual ledger for every client, and retain those records for a set period. The wording and the retention period differ by state, so check your own bar’s rule — but the three records a three-way reconciliation ties together are the same everywhere, because they are the records the rule itself demands. New York’s version is used as the worked example below.
New York’s Rule 1.15 of the Rules of Professional Conduct (22 NYCRR Part 1200) requires lawyers to keep client funds in a separate account, maintain complete records of every deposit and withdrawal, keep individual records for each client, and preserve those trust records for seven years. The three-way reconciliation is the accepted method for demonstrating that those records are accurate and that no client’s funds have been touched by another’s matter. If a grievance or a random audit lands on your desk, a clean monthly three-way reconciliation is your first and best line of defense.
Most practitioners reconcile monthly. Even where a specific cadence isn’t spelled out, monthly is the practical standard, because errors are far easier to find within 30 days than after a year of activity.
Step-by-step: how to perform a three-way reconciliation
- Pick a cutoff date. Use the bank statement closing date so all three records cover the same period.
- Reconcile the bank to the book. Start with the ending bank statement balance, add deposits in transit, subtract outstanding checks. This adjusted bank balance should equal your trust checkbook/control balance.
- Total every client ledger. List each client (and third-party) sub-account and its ending balance. Add them up.
- Compare all three. Adjusted bank balance = book balance = sum of client ledgers. All three must be identical.
- Investigate any difference immediately. A mismatch is never “close enough.” Trace it to the transaction.
- Document and retain. Save the reconciliation, the bank statement, and the client-ledger detail. In New York, keep them seven years.
Worked example
A three-attorney firm’s trust account shows a bank statement balance of $52,400 at month-end. There is one outstanding settlement check for $12,000 and a $3,600 deposit in transit. Adjusted bank balance: $52,400 − $12,000 + $3,600 = $44,000. The trust checkbook control balance also reads $44,000 — the two-way ties out. Now the client ledgers: Client A $18,000, Client B $9,500, Client C $14,000, Client D $2,500. Total = $44,000. All three agree; the account is in balance.
Now change one fact: the bank charged a $35 wire fee directly against the trust account. Suddenly the adjusted bank balance is $43,965 while the client ledgers still total $44,000 — a $35 shortfall of client money. In New York, bank charges must never be paid out of client funds; the fee has to be reimbursed from the firm’s own operating account. The reconciliation is what surfaces that $35 before it becomes a violation.
Monthly three-way trust reconciliation worksheet
Use this at every month-end for each IOLTA or trust account. Three totals must agree to the cent. Your state’s rule sets the exact record and timing requirements, so confirm them with your bar’s trust-account guidance.
| Line | What to enter | Source |
|---|---|---|
| A | Trust bank statement ending balance | Bank statement |
| B | Add: deposits in transit | Deposits booked in the ledger but not yet on the statement |
| C | Less: outstanding checks and pending disbursements | Checks issued but not yet cleared |
| D | Adjusted bank balance (A + B – C) | Calculated |
| E | Trust checkbook (control) balance | Trust account register or general ledger |
| F | Sum of all client ledger balances | Client trust ledger report as of the same date |
| G | Tie-out check: D = E = F? | If not, work the mismatch list below |
If the three do not tie, check these five first
- Bank versus checkbook: uncleared deposits or checks missing from the register, bank fees, or a deposit posted to the wrong account.
- Checkbook versus client ledgers: a disbursement or deposit posted to the control account but not to a client ledger, or the reverse.
- Negative client balance: a disbursement exceeding the funds held for that client, which means another client’s money was used.
- Earned fees left in trust: fees that have been earned and billed but not yet moved to the operating account.
- Client costs booked as expenses: costs advanced for a client recorded as firm expense, or paid from trust without being recorded against the client.
Month-end sign-off checklist
- Bank statement, register and client ledger report all dated to the same day
- Reconciliation signed and dated by the person who prepared it and by the attorney who reviews it
- Every mismatch explained in writing and cleared or scheduled for correction
- Records kept for the period your state requires

A three-way reconciliation that has never balanced is a disciplinary matter waiting to happen
Bank, book and client ledgers must agree to the penny, every month. When they do not, the usual cause is not theft but drift: a fee taken a day early, a cost advanced from the wrong account, a stale outstanding cheque. The grievance committee does not distinguish between sloppy and dishonest until well into the process.

Common causes of a three-way that won’t tie
- Bank fees taken from trust — the classic $35 problem above; fund fees from operating, not trust.
- Disbursing against uncollected funds — writing a check before a client’s deposit actually clears.
- Posting to the wrong client ledger — the two-way still balances, but two client ledgers are wrong.
- Missing or duplicated ledger entries — a deposit recorded in the checkbook but not on a client ledger (or vice versa).
- A negative client ledger — the golden rule of trust accounting is that no individual client ledger may ever go negative; if one does, you have disbursed another client’s money and must correct it immediately.
- Earned fees left sitting in trust — money you’ve earned must be moved to operating; leaving it commingles funds.
Frequently asked questions
What is the difference between two-way and three-way reconciliation?
Two-way reconciliation matches the bank statement to your checkbook. Three-way adds a third check: the total of all individual client ledgers must also equal that balance. Only the three-way proves that each client’s money is intact.
How often should a law firm reconcile its trust account?
Monthly is the standard. Reconciling every month, against each bank statement, keeps errors small and easy to trace and demonstrates ongoing compliance if you are ever audited.
Does New York require three-way reconciliation by name?
Rule 1.15 requires separate client funds, complete and individual client records, and seven-year retention. The three-way reconciliation is the accepted method for proving those records are accurate, which is why compliant firms perform it.
Can bank fees be paid from my IOLTA account?
No. Bank charges and fees must not be paid out of client funds. Fund them from your operating account; if the bank debits trust, reimburse it promptly and document the correction.
What happens if my trust account doesn’t balance?
Stop and investigate before any further disbursement. An out-of-balance trust account can mean one client’s funds were used for another’s matter — a serious ethics violation. Identify the transaction, correct it, and document the fix.

When the three-way does not balance
A reconciliation that will not tie is a diagnostic problem, not a bookkeeping one — and the order you check things in matters. We work through the causes, from outstanding items and bank errors to the serious ones, in what to do when your attorney trust account does not balance.

Firms that cannot complete this procedure reliably each month usually have a staffing problem rather than a knowledge problem, which is the case for outsourcing the monthly law firm bookkeeping and treating the reconciliation as a fixed deliverable with a date on it.
