The retainer is spent, the client is happy, and the file is sitting in your out tray. That is exactly the moment things go sideways. A file that is almost closed is a file that still has a trust balance, an unsent reporting letter, and no destruction date. Closing well is not a formality. It is the last chance to catch a problem while you still remember the matter, and the first line of defence if a complaint lands two years from now.
Here is a checklist you can actually run through, in order, every time. Nothing exotic. Just the steps that keep files clean and keep you out of trouble.
1. Confirm the work is truly finished
Before anything else, prove to yourself that there is no work left. A file that gets closed with a loose end is worse than one left open, because the tickler is gone and nobody is watching it anymore.
- Is every deliverable done and delivered? The signed agreement, the registered transfer, the filed materials, the order as entered.
- Are there any dates still running? An appeal window, a limitation period on a related claim, a filing deadline. If a date is live, the file is not closed.
- Have you followed up on anything you promised to do "later"? Search your own emails for the phrases you use when you defer something.
- Is there an outstanding undertaking, to opposing counsel or to a registry? Undertakings do not close with the file.
Warn. A live limitation period does not disappear because the retainer ended. If a related claim could still be brought, note the date somewhere that will alarm someone, and say so in writing to the client.
2. Zero out the trust balance and reconcile
This is the step that gets firms into real trouble with the law society, so treat it as non-negotiable. No file closes with money sitting in trust.
- Pull the trust ledger for the matter and read the current balance.
- Render a final invoice for any earned fees and disbursements, and transfer that amount out of trust with the client's authorization on record.
- Return the remainder to the client by cheque or transfer, and keep proof of how you sent it.
- Reconcile the matter ledger to zero, and confirm the client's trust listing shows nothing outstanding.
- File the final trust reconciliation with the rest of the closing documents so it travels with the file.
If the leftover amount is trivial and the client is unreachable, do not just leave it. Every province has an unclaimed trust process. Follow it rather than parking the money indefinitely.
3. Set the retention and destruction date now
The single most common failure is closing a file without deciding when it can be destroyed. Do it now, while the matter is fresh, because you will never do it later.
Retention periods vary by matter type and by your law society's rules, so build your own schedule and apply it consistently. A rough working guide:
| Matter type | Typical retention | Keep permanently? |
|---|---|---|
| General litigation and solicitor files | Follow your law society minimum, often several years past closing | No |
| Real estate and corporate records | Longer, given later reliance | Often the key instruments |
| Wills, estates, minors' matters | Extended or indefinite | Yes, usually |
| Original client property and executed originals | Return to client on closing | Not your call to destroy |
Tip. Record the destruction date as a real calendar entry, not a note buried in the file. Whatever practice management system you use, A1 CMS included, the closing step should stamp a date the system will actually surface when it arrives.
Two things people forget: original documents that belong to the client are returned, not destroyed, and anything you keep permanently should be flagged so a future clean-out does not sweep it away.
4. Send the closing letter and return the file
The closing letter is short, but it does a lot of work. It marks the end of the retainer, so there is no argument later about whether you were still acting.
A good closing letter says, plainly:
- The matter is concluded and the retainer has ended as of this date.
- What the outcome was, in one or two sentences.
- What you are enclosing or returning, and what you are keeping.
- Any live date the client must watch on their own now, and any renewal or follow-up they should diarize.
- How long you will keep the file and that it will be destroyed after that.
A closing letter fixes the end of the retainer in writing, which matters when a dispute arises later. Every risk manager, roughly
Return the client's original documents and property with the letter, or arrange pickup. Get a receipt for anything valuable.
5. Archive so future you can find it
A closed file you cannot locate is nearly as bad as no file at all. When the complaint or the follow-up matter arrives, you want to pull the whole thing in a minute, not spend an afternoon in the storage room.
- Store it under a consistent naming pattern, by client and matter, the same way every time.
- Keep the closing letter, final invoice, and trust reconciliation together at the front.
- Make sure it is searchable by client name, matter type, and closing date.
- Confirm your backup actually captured the digital version before you consider it filed.
If you want to see how a tidy closing process connects to the rest of your workflow, our notes on standard operating procedures and the broader practice management writing cover the habits that make closing routine rather than a scramble.
Run these five steps in order and closing stops being the thing you dread at year end. The trust balance is zero, the letter is on file, the destruction date is in the calendar, and the archive is where you left it. That is a file that closes clean and stays defensible, which is the whole point. Do it the same way every time, and future you will be grateful.
