Three-Way Reconciliation: How the Control Works
Compare the adjusted bank balance, trust account book balance, and total of client ledgers as of the same date. Disbo automates that comparison continuously for applicable customers and flags differences for human review.
The short answer
What is three-way reconciliation?
Three-way reconciliation compares three balances as of the same cutoff date: (1) the adjusted bank balance after documented outstanding items, (2) your trust account book balance from your internal ledger, and (3) the total of every individual client matter sub-ledger. A difference is an exception to investigate and document; software can surface it, but the firm decides the appropriate correction and response.
Requirements vary: Use the cadence, cutoff, sign-off, retention period, and record format required by the authority governing each trust account. Continuous comparison does not replace a required period-end review or certification.
How to complete a three-way reconciliation
A practical six-step control. Adapt the cadence, records, and approval to the rules governing your firm and account.
Obtain the bank statement
Obtain the bank statement or official bank activity for the reconciliation period. Note the ending balance and cutoff date, then list documented reconciling items such as outstanding checks, deposits in transit, and bank adjustments.
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 the individual client ledgers included in the trust account through the same cutoff date. Sum those balances to calculate the total funds attributed at the sub-ledger level.
Reconcile bank balance to book balance
Adjust the bank ending balance for valid, documented reconciling items such as deposits in transit, outstanding checks, and bank adjustments. Compare it with the book balance and investigate any difference.
Confirm book balance = sum of client sub-ledgers
Compare the total of the applicable client ledgers from Step 3 with the book balance. A difference is a sub-ledger exception that requires investigation against entries and source records.
Document and retain the reconciliation
Record the cutoff date, bank balance, adjustments, adjusted bank balance, book balance, client-ledger total, exceptions, corrections, and reviewer. Retain the record and source documents for the period and in the form your governing authority requires.
Where the control applies—and where judgment remains
Disbo's automatic or continuous three-way reconciliation is live for applicable customers. Applicability depends on the account, supported connections, available records, and configuration.
Applicable workflows
- Supported IOLTA or trust accounts whose bank activity and ledger records are available to Disbo.
- Client or matter balances maintained in the connected, configured workflow.
- Teams that need differences surfaced between formal reconciliation dates, not only at month-end.
Important limitations
- Missing, delayed, duplicated, or incorrectly mapped source data can affect the comparison.
- Outstanding checks, deposits in transit, bank adjustments, and corrections still require review.
- Disbo does not decide legal entitlement, make accounting judgments, or guarantee compliance.
Common reconciliation failure points
These process gaps can make a reconciliation incomplete or hard to defend. The legal consequence depends on the governing rules and facts.
Not completing it on time
A continuous comparison does not itself prove that a required statement-period review, sign-off, or certification was completed. Map the workflow to the firm's governing rules and calendar.
Not keeping the documentation
A balanced screen is not a substitute for preserving the reconciliation record and underlying source documents in the form and for the period the firm is required to maintain.
Combining client matters
The ledger total should be built from the client or matter-level records required for the account. Aggregating too early can hide which balance produced an exception.
Carrying forward unresolved discrepancies
Do not force a balance with an unexplained entry. Preserve the exception, investigate timing and source records, document any correction, and route legal or accounting questions to the responsible professional.
Treating recorded funds as cleared funds
A ledger entry and a bank's availability or collected-funds status are different facts. Reconciliation supports review but does not decide whether funds are legally or operationally available to disburse.
Automatic or continuous three-way reconciliation
For applicable customers, Disbo automatically or continuously compares the available bank balance or activity, trust account book balance, and aggregate of connected client ledgers. When those records do not agree, Disbo flags the difference for review. That gives the firm an earlier control signal while preserving human responsibility for the investigation, adjustment, and formal close.
Available balances are compared automatically or continuously instead of relying only on a manually assembled worksheet.
The control compares bank data, the trust account ledger, and the total of connected client ledgers at a common cutoff.
A difference is flagged so an authorized person can inspect timing, outstanding items, mappings, entries, and source records.
Available reconciliation, payment, approval, and ledger records can support an exportable compliance or state-bar audit package.
Frequently asked questions
What is three-way reconciliation for IOLTA trust accounts?
Three-way reconciliation compares three balances as of one cutoff date: (1) the adjusted bank balance, (2) the trust account book balance, and (3) the total of the individual client ledgers. Differences are investigated and documented.
How often is three-way reconciliation required?
Cadence, deadlines, sign-off, and record format vary by jurisdiction and account. Follow the current rule and official guidance governing each trust account. Continuous software comparison does not replace a required period-end review or certification.
What happens if the three balances don't agree?
Treat it as an exception to investigate. Check timing, outstanding items, bank activity, ledger entries, matter assignments, and corrections. The responsible lawyer or accounting professional should determine and document the required response.
What records does three-way reconciliation require?
Use the bank statement or connected bank activity, trust account general ledger, applicable client ledgers, and a reconciliation record showing the cutoff date, all three balances, adjustments, exceptions, and corrections.
Can software automate three-way reconciliation?
Yes. Automatic or continuous three-way reconciliation is live for applicable Disbo customers. It compares available bank, trust-account-journal, and client-ledger balances and flags differences for review. Timing and coverage depend on supported accounts, connections, available data, and configuration.
