Form 9 Trust Reconciliation for Ontario Lawyers: Step-by-Step Guide (2026)

LSO By-Law 9 requires every Ontario lawyer and paralegal holding trust funds to complete a monthly trust reconciliation. Here's what the reconciliation must include, how to complete it correctly, and what happens when it doesn't balance.

What Is the Form 9 Trust Reconciliation?

Under LSO By-Law 9, Part IV (s. 17–22), Ontario lawyers and licensed paralegals who maintain trust accounts must perform and record a monthly trust reconciliation. The LSO refers to this as "Form 9" — the format for the monthly trust comparison.

The reconciliation must be completed by the 25th day of the month following the month being reconciled. If you hold no trust funds in a given month, you must still complete the reconciliation and note that the balance is zero.

By-Law 9 requirements at a glance:

— Must be completed every month without exception (even with zero trust balance)
— Must be completed by the 25th of the month following the period being reconciled
— Must reconcile the trust bank balance against the total of all client trust ledger balances
— Must identify and explain any discrepancy
— Must be signed by the lawyer or paralegal
— Must be retained for 10 years (lawyers) or 6 years (paralegals)

The Three Parts of the Monthly Trust Reconciliation

A properly completed Form 9 has three components that must all reconcile to the same number:

Part 1: Trust Bank Balance

Start with the closing balance on the trust bank statement for the month
Add: deposits shown in your trust ledger but not yet cleared on the bank statement (outstanding deposits)
Subtract: cheques or EFTs issued but not yet cleared on the bank statement (outstanding cheques)
Result: Adjusted trust bank balance

Part 2: Client Trust Ledger Total

List every client who has funds on trust (or had transactions during the month)
For each client, calculate: opening balance + all receipts − all disbursements = closing balance
No client balance may be negative
Sum all client closing balances
Result: Total client trust ledger balance

Part 3: Comparison (They Must Match)

Adjusted trust bank balance (from Part 1) must equal Total client trust ledger balance (from Part 2)
If they match: sign and date the reconciliation, file it
If they don't match: investigate immediately — do not sign an unbalanced reconciliation
Discrepancies must be identified, explained, and corrected before the next month

Worked Example: February 2026 Trust Reconciliation

Assume a solo Ontario lawyer with three active trust clients:

Client	Opening Balance	Receipts	Disbursements	Closing Balance
Smith RE Purchase	$5,000.00	$180,000.00	$183,500.00	$1,500.00
Jones Litigation	$2,500.00	$0.00	$1,200.00	$1,300.00
Brown Estate	$0.00	$45,000.00	$0.00	$45,000.00
TOTAL				$47,800.00

Part 1: Bank Reconciliation

February 28 bank statement balance$48,300.00

+ Outstanding deposits (Brown deposit cleared March 2)$0.00

− Outstanding cheques (Smith disbursement not cleared)($500.00)

Adjusted bank balance$47,800.00

✓ Adjusted bank balance ($47,800.00) = Total client ledger balance ($47,800.00)

Reconciliation balances. Sign, date, and file.

Common Form 9 Errors — and How to Avoid Them

✗ Error: Forgetting to include zero-balance clients

If a client had a trust account earlier in the year but now has a zero balance, they still need to appear in the ledger with a $0.00 closing balance — not just be omitted.

Fix: Keep all clients in the trust ledger even after their balance reaches zero. Archive them only after the matter closes.

✗ Error: Not tracking outstanding items

Deposits or cheques issued in the month but not cleared by month-end are the most common reconciliation error source. Forgetting to include them creates a false discrepancy.

Fix: Generate an outstanding transactions report from your bank portal at month-end. Reconcile this against your ledger.

✗ Error: Negative balance on a client ledger

A negative client balance means you disbursed more than the client had on trust. This is always a violation, even if temporary. The reconciliation will not balance if any client has a negative balance.

Fix: Configure software alerts to warn before any disbursement that would take a client negative.

✗ Error: Recording in the wrong month

A receipt or disbursement must be recorded in the month it occurred — not the month it's entered. A February disbursement recorded in March will cause both months to fail reconciliation.

Fix: Record transactions contemporaneously. Set a hard rule: no backdating.

✗ Error: Skipping months with no activity

If you hold trust funds but have no transactions in a month, you still must complete the Form 9 showing the static balance carried forward.

Fix: Set a calendar reminder for the 20th of every month: complete Form 9 by the 25th regardless of activity.

How Software Simplifies the Monthly Reconciliation

The manual Form 9 reconciliation — with a spreadsheet and bank statement — is error-prone and time-consuming. Modern practice management software reduces this to a 5-minute monthly task:

Per-client trust ledger auto-maintained

Every trust receipt and disbursement is immediately reflected in the client ledger balance — no end-of-month tallying required.

One-click reconciliation CSV export

Export the full trust ledger summary (RFC 4180-compliant) matching the Form 9 format. Import into your bank reconciliation or submit as your record.

Negative balance prevention

Real-time alerts before any disbursement that would take a client negative — so you never create a reconciliation problem.

Morning briefing trust summary

Daily email with all client trust balances, flagging negatives and unusual changes. Catch errors immediately, not at month-end.
