Three-Way Reconciliation: The Core IOLTA Requirement
Every U.S. state bar requires attorneys to reconcile their IOLTA trust accounts using a three-way reconciliation. Here's what it is, why it matters, how to do it, and the most common mistakes that trigger bar discipline.
The short answer
What is three-way reconciliation?
Three-way reconciliation is the process of confirming that three independent balances all match as of the same date: (1) the bank statement balance for your IOLTA trust account, (2) your trust account book balance from your internal ledger, and (3) the total of every individual client matter sub-ledger. All three figures must agree exactly. If they don't, there's a problem that must be identified and corrected before any further disbursements.
Required frequency: 47 of 51 jurisdictions require monthly reconciliation. CO, CT, LA, and NC require at least quarterly. No state allows less than quarterly.
How to complete a three-way reconciliation
Six steps required by every state bar that mandates three-way reconciliation of IOLTA trust accounts.
Obtain the bank statement
Pull the monthly bank statement for your IOLTA trust account. Note the ending balance and the statement date. List any outstanding items: checks issued before the statement cutoff that haven't cleared, and deposits not yet reflected.
Update and total your trust account ledger
Update your trust account general ledger for all transactions through the statement date. Every receipt and disbursement gets its own entry: date, amount, payee or source, and purpose. Calculate the book balance as of that same date.
Total all client matter sub-ledgers
Update every individual client matter sub-ledger through the statement date. Sum all matter balances to get total client funds on deposit. Every active matter needs its own separate ledger — you cannot combine matters even for the same client.
Reconcile bank balance to book balance
Adjusted bank balance = Bank statement balance + Deposits in transit − Outstanding checks. This adjusted figure must equal your book balance from Step 2. Any discrepancy here must be identified and corrected before moving on.
Confirm book balance = sum of client sub-ledgers
The total of all client matter balances from Step 3 must equal your book balance from Step 2. If they don't match, there's a client-ledger discrepancy — meaning some client's funds are either over- or under-recorded in their sub-ledger.
Document and retain the reconciliation
Record the reconciliation in a worksheet showing: the date, bank balance, adjusted bank balance, book balance, client ledger total, any outstanding items listed individually, and the name of the person completing it. Retain per your state's rules — typically 5–7 years.
Reconciliation frequency by state
Monthly is universal best practice. These are the states where the bar sets a quarterly minimum.
| State | Minimum frequency | Note |
|---|---|---|
| All other 47 states + DC | Monthly | Monthly three-way reconciliation required |
| Colorado | Quarterly minimum | RPC 1.15B — most firms reconcile monthly |
| Connecticut | Quarterly minimum | Rule 1.15 — most firms reconcile monthly |
| Louisiana | Quarterly minimum | Rule 1.15 — most firms reconcile monthly |
| North Carolina | Quarterly minimum | Rule 1.15 — most firms reconcile monthly |

Common three-way reconciliation violations
These are the mistakes that generate bar complaints and audits most frequently.
Not completing it on time
Monthly states mean you have 30 days from the statement date — not from when you get around to it. Missing the window, even by a few days, is a violation in states that specify a completion deadline.
Not keeping the documentation
The reconciliation must be documented and retained. Completing the math but not saving the worksheet — or saving it in a format you can't produce during an audit — is treated the same as not completing it at all.
Combining client matters
Three-way reconciliation requires the sum of individual matter sub-ledgers, not a single client total. Attorneys who track one balance per client instead of one per matter are producing an incomplete reconciliation.
Carrying forward unresolved discrepancies
A discrepancy must be found and corrected before the reconciliation is finalized. Completing the reconciliation with a known discrepancy noted as 'TBD' is not compliant — the bar expects a resolved, balanced reconciliation every period.
Disbursing on uncleaned funds
Disbursing against a deposit that hasn't actually cleared at the issuing bank creates an overdraft risk. If the deposit reverses, the client's balance goes negative. Reconciliation should flag cleared vs. pending balances.
Continuous reconciliation, not monthly
Disbo doesn't wait for month-end to run three-way reconciliation. The platform compares bank feed data, your trust ledger, and every client matter sub-ledger continuously — in real time. Any discrepancy is flagged the moment it appears, with specific diagnostic information showing which balances don't agree and which transactions may be the cause.
Discrepancies are flagged immediately — not discovered at month-end when the damage is already done.
Every reconciliation period is documented automatically with a properly formatted, retrievable report — no manual worksheet required.
Disbo blocks any disbursement that would create a negative client matter balance before it processes — the most common reconciliation problem eliminated at the source.
When the bar requests reconciliation records, export a complete package — all periods, all client ledgers, all supporting documentation — in under a minute.
Frequently asked questions
What is three-way reconciliation for IOLTA trust accounts?
Three-way reconciliation is the process of confirming that three independent balances all match as of the same date: (1) the bank statement balance, (2) your trust account book balance, and (3) the total of every individual client matter sub-ledger. All three must agree exactly.
How often is three-way reconciliation required?
Forty-seven of 51 U.S. jurisdictions require monthly three-way reconciliation. Colorado, Connecticut, Louisiana, and North Carolina require it at least quarterly. No state allows less than quarterly. Monthly is the safe standard regardless of your state's minimum.
What happens if the three balances don't agree?
You must find and correct the source of the discrepancy before closing the reconciliation. Carrying an unresolved discrepancy forward is itself a violation. If the discrepancy indicates a shortage in a client's sub-ledger, the client may need immediate restoration of funds.
What records does three-way reconciliation require?
You need: the monthly bank statement, your trust account general ledger, individual client matter ledgers for every active matter, and the reconciliation worksheet itself showing all three balances, the date, any outstanding items, and the responsible attorney's name.
How long must reconciliation records be retained?
Most states require 5 years after the conclusion of each matter. Seven states require 7 years: Colorado, Illinois, New Jersey, New York, Ohio, Washington, and Wisconsin — and Maine requires 8. If you practice in multiple states, retain for 8 years across the board.
Can software automate three-way reconciliation?
Yes. Disbo performs three-way reconciliation continuously rather than monthly — comparing bank feed data, the trust ledger, and client sub-ledgers in real time. Any discrepancy is flagged immediately, and the required documentation is generated automatically for every period.
