The IOLTA Three-Way Reconciliation Guide (for solo and small firms)
IOLTA Three-Way Reconciliation
What it is, why your bar requires it every month, and how to get it right
Bookkeeping & CFO-Level Reporting for Law Firms
If you hold client money, your trust account is the single most dangerous thing on your books. A misplaced dollar in your operating account is an accounting headache. A misplaced dollar in your IOLTA is a bar complaint. Disciplinary records in every state are full of attorneys who never stole a cent but lost their license anyway, because they couldn’t prove where the money was.
Three-way reconciliation is how you prove it — every month, in writing. Done consistently, it is the difference between an account you can defend in an audit and one that quietly drifts out of balance until someone notices. Here’s exactly what it is, why the cadence matters, the four errors that cause most of the trouble, and a worked example you can follow line by line.
What three-way reconciliation actually is
Three-way reconciliation is the monthly process of confirming that three completely separate records of your trust account balance all agree — to the penny. Not approximately. Not “close enough.” Identical.
The word “three-way” matters. A standard bank reconciliation matches two numbers: your books against the bank. That tells you the account balances overall, but it says nothing about whether each client’s money is actually there. A trust account can reconcile perfectly to the bank while one client’s funds have quietly been spent on another client’s matter. The third leg — the individual client ledgers — is what closes that gap and proves no client’s funds have been touched.
Why the bar requires it every month
Almost every state bar requires trust-account reconciliation on a monthly cadence, performed promptly after the bank statement closes, documented in writing, reviewed by a responsible attorney, and retained for years in case of audit. The specifics vary by jurisdiction, but the monthly rhythm is nearly universal — and it exists for a practical reason.
Errors in a trust account compound silently. A single misposted transfer is easy to find in a thirty-day window of activity. The same error left for a year is buried under thousands of transactions, and by then the money it represents may already be gone. Monthly reconciliation keeps the search small. It also creates the paper trail regulators expect: when the bar asks you to demonstrate compliance, “we reconcile every month and here are the signed records” is a complete answer. “We’ll get to it” is not.
The compliance reality
Most trust-account discipline isn’t about theft. It’s about attorneys who couldn’t produce reconciliations on demand. The reconciliation itself is the evidence of compliance — which is why the cadence, the documentation, and the attorney review all matter as much as the math.
The three records you reconcile
Every three-way reconciliation lines up these three figures. When all three match, your account is in balance and every client’s money is accounted for.
| Record | What it represents |
|---|---|
| 1. Bank statement balance | The actual cash sitting in the trust account, as reported by the bank — adjusted for outstanding checks and deposits in transit. |
| 2. Trust account register (book balance) | Your firm’s own running ledger for the whole account — the checkbook of the trust account, tracking every deposit and disbursement you’ve recorded. |
| 3. Sum of all client ledgers | Every individual client’s trust balance, added together. This proves the money is allocated correctly client by client — not just present in total. |
The order they’re listed isn’t the order you trust them. The bank statement is ground truth for how much cash exists. The client ledgers are ground truth for who that cash belongs to. The register is your record connecting the two — and it’s the one most likely to contain the error when they don’t agree.
The four errors that sink trust accounts
When a reconciliation won’t tie out, the cause is usually one of these four. Each one is ordinary, easy to commit, and serious if left uncorrected.
1. Commingling
Commingling is mixing firm money with client money — the cardinal sin of trust accounting. It happens in small, well-intentioned ways: leaving an earned fee in the trust account “until later,” covering a client’s cost shortfall out of the pooled balance, or running a personal or operating expense through the IOLTA because that’s the card that was handy. The fix is a bright line: client money goes in, only that client’s money comes out, and firm money never rests there. The reconciliation catches commingling when the client ledgers and the register stop agreeing.
2. Earned vs. unearned fees left in trust
Unearned fees — a retainer paid up front — belong in trust until you actually do the work. The moment you earn against that retainer, the earned portion must be moved out to your operating account promptly. Two opposite mistakes both create exposure: leaving earned fees sitting in trust (which is a form of commingling), or pulling fees out before they’re earned (which is spending client money). Clean reconciliation depends on each client’s ledger reflecting only what is genuinely still theirs.
3. Bank fees charged to the trust account
Banks charge maintenance fees, wire fees, and returned-item fees, and they will happily deduct them straight from the IOLTA. The problem: those dollars belong to clients, so a bank fee paid from trust is client money spent on a firm expense. Account analysis fees on a true IOLTA are typically handled through the IOLTA program, but other fees are not — they must be reimbursed from operating, and the account should be structured so fees never erode client balances. A fee that slips through shows up as a small, nagging gap between the bank balance and what clients are owed.
4. Returned (bounced) checks
A client’s deposit clears on paper, you credit their ledger, and then the check bounces a week later. For that window, you’ve effectively disbursed money the account never actually held — often funding one client’s matter with another client’s cash. Never disburse against a deposit until it has truly cleared, and when a returned item appears on the statement, reverse it immediately on the client’s ledger. Reconciliation is what surfaces the reversal before it becomes a shortfall.
A worked example
Consider a small firm’s IOLTA at the end of the month, holding money for three clients:
| Client matter | Trust balance |
|---|---|
| Henderson — real estate closing | $9,600 |
| Patel — settlement funds held | $2,000 |
| Wright — unearned retainer | $3,500 |
| Total of client ledgers | $15,100 |
Now we line up all three records:
| Record | Balance |
|---|---|
| Bank statement ending balance | $15,540 |
| Less: outstanding check #2051 to title company (not yet cleared) | − $440 |
| Adjusted bank balance | $15,100 |
| Trust account register (book balance) | $15,100 |
| Sum of client ledgers | $15,100 |
All three tie to $15,100. The account is in balance, and we can prove each client’s money is present. That’s a clean three-way reconciliation.
Now watch what one of our four errors does to it.
Suppose the bank quietly charged a $35 wire fee to the IOLTA this month. The bank statement now ends at $15,505 instead of $15,540, so the adjusted bank balance falls to $15,065 — while the register and the client ledgers both still say $15,100. The reconciliation no longer ties:
| Record | Balance |
|---|---|
| Adjusted bank balance (after $35 fee) | $15,065 |
| Sum of client ledgers | $15,100 |
| Shortfall in client funds | − $35 |
That $35 gap means the account is now holding $35 less than clients are owed — the bank spent client money on a firm expense. The fix is immediate: reimburse the trust account $35 from operating funds, restore the bank balance to $15,100, and arrange for the bank to bill all future fees to the operating account. Caught this month, it’s a five-minute correction. Caught a year from now, it’s a $400-plus shortfall with no clear record of how it happened — exactly the kind of finding that triggers a bar inquiry.
This is the whole point of the third leg.
A two-way bank reconciliation might have been coaxed into balancing by simply recording the fee. Only by holding the client-ledger total as the fixed reference — the money you owe — does the shortfall reveal itself for what it is.
Your monthly reconciliation checklist
The work is repeatable, which is exactly why it should be done the same way every month. We’ve put the full sequence — from gathering statements through attorney sign-off — into a one-page checklist you can download, print, and initial each month for your records.

None of this is complicated in isolation. The difficulty is doing it correctly, completely, and on time, twelve months a year, while you’re also practicing law. The firms that get into trouble rarely lack the ability — they lack the bandwidth, and the trust account is the first thing that slips when a quarter gets busy.
That’s the case for handing it to someone who does nothing else. We hit a clean three-way reconciliation on your trust account every month, document it the way your bar expects, and flag anything that needs your attention before it becomes a problem. But finishing the reconciliation is only half of what gives you peace of mind. The other half is being able to see it.
A reconciliation you can’t see isn’t peace of mind
Here’s where most bookkeeping stops — and where ours doesn’t. A traditional bookkeeper closes the month, emails you a PDF profit-and-loss, and you file it away. That report is a photograph: accurate the day it was taken, out of date the moment something changes, and silent on the one question that actually keeps a law-firm owner up at night — is my trust account clean right now?
Most bookkeepers hand you a report. We hand you a command center.
Every Cypress Books client gets a private, secure dashboard, available 24/7, with all of their financial data in one place — and your most recent three-way reconciliation sits right there, timestamped, the moment it’s complete. You don’t wait for an email, dig through your inbox, or call us to ask where things stand. You log in at 11 p.m. before a closing, or the morning a client questions their retainer, and the answer is already on the screen, in plain English: trust account reconciled, every client ledger accounted for, as of a date you can point to.
That is the difference between a monthly P&L and a living dashboard. A P&L tells you what happened last month. The dashboard tells you where you stand today — trust status, cash position and runway, AR aging, your real take-home, a plain-language business health score — and it refreshes as your numbers do. One is a record you receive and set aside. The other is visibility you can act on: the financial clarity growing firms pay fractional CFOs thousands of dollars a month to provide, included in every ongoing engagement.
So when the bar comes calling, when a client questions a disbursement, or when you simply want to close the laptop at night knowing the most dangerous account on your books is clean — you don’t go hunting for proof. You open your dashboard, and it’s already there.
Your books are never a project we get to eventually. They’re a living record we maintain with the same care every single month.
Want your trust account reconciled, defensible, and visible the moment you want to check it?
