Closed-file retention policy for a small firm: a template and the state-by-state question

How long must a law firm keep a closed client file?

Last reviewed: 30 October 2026. This is organisational information, not legal advice. We cannot give you a period, because there is none that applies everywhere. In the United States, retention is set by state bars (through ethics opinions and rules on trust records) and varies. Publications we reviewed discuss, for example, a California proposed formal opinion (Interim No. 19-0004, reissued in 2026 and described as proposed), Illinois State Bar material, Washington State Bar commentary and an old Alabama opinion. We have not verified the periods in each, so we do not repeat them here.

The honest answer is a method: find your regulator's rule for client files and for trust records, ask your professional-indemnity or malpractice insurer what they expect, take the longest applicable period for each category, and write it down.

How do you find your own period?

1. 1

   Regulator

   Search your bar or law society's website for record retention, file retention and trust accounting records. Note the document and date.

2. 2

   Ethics opinions

   Look for opinions on closed files, client property and destruction. Note whether they are binding rules or guidance.

3. 3

   Insurer

   Ask your insurer or loss-prevention service for their recommended period. Many publish one.

4. 4

   Limitation law

   Find limitation periods for claims against lawyers in your jurisdiction. Some firms keep files at least that long.

5. 5

   Other laws

   Check tax, anti-money-laundering and data protection rules, which can require keeping or deleting records.

6. 6

   Choose

   Take the longest for each category and write it into the policy with the source and date checked.

What categories should the policy cover?

What goes in the policy?

A one-page skeleton to adapt:

1. Purpose and scope: which matters and media.
2. Roles: who sets the schedule, who approves destruction.
3. Retention triggers: period runs from closing date; extended by litigation hold, regulator request or open claim.
4. Schedule by category (table above) with source and date checked.
5. Closing routine: closing letter, return originals, set the retention date, record storage location.
6. Destruction: approval, secure method, destruction log with matter number, date, approver and category.
7. Client notice: a sentence in the engagement letter about how long files are kept and what happens afterwards.
8. Review: annually and when rules change.

The closing letter and engagement-letter wording should come from a lawyer who knows your jurisdiction. We do not reproduce sample wording here.

What is the destruction log, and what are the traps?

A destruction log is a table showing what was destroyed, when, by whom, with whose approval and under which policy version. It is the evidence that destruction followed policy rather than convenience.

• Destroying a file with an open claim, investigation or hold.
• Forgetting backups and email, so 'destroyed' files persist.
• Setting the date from the last bill instead of the closing date.
• Never setting a date, so nothing is ever reviewed.
• Destroying originals that belong to the client.

• Closing a matter: a checklist
• Legal matter lifecycle
• Exporting your matter data from Notion

Where MatterOS fits

We make MatterOS, a Notion template for lawyers, so weigh our view accordingly. This page is organisational information, not legal advice.

MatterOS ($39 one-time) is a Notion template. You can add closed date, retention date and destruction approval as properties on each matter and filter a view for files due for review. It does not set the period, hold trust records or destroy anything for you. Remember that data lives in your own Notion workspace, so retention there is your responsibility; check Notion's deletion behaviour as well.

Frequently asked questions

How long should a law firm keep client files after closing?

It depends on your jurisdiction, the type of record and your insurer. There is no universal period. Find your regulator's rules and ethics opinions, ask your insurer, and adopt the longest applicable period for each category, writing down the source and date checked.

What should a law firm retention policy include?

Scope, roles, triggers for the retention clock, a schedule by category, a closing routine, a destruction procedure with approval and log, a client notice in the engagement letter, and an annual review. Keep it to one or two pages.

Can I destroy a client file without telling the client?

Rules differ, and original documents belong to the client. Many bars expect the policy to be communicated, often in the engagement letter, and some expect notice before destruction. Check your regulator's guidance before destroying anything.

Do trust account records have a separate retention period?

Often yes. Trust and client-money records are usually governed by specific regulator rules that can differ from general file retention. Confirm the period for your jurisdiction separately and keep those records on their own schedule.

Should I keep electronic files as long as paper files?

Generally treat them alike. Include emails, documents and database entries in the schedule, and remember backups. Deleting a document from one place while copies persist elsewhere leaves you with neither a clean destruction nor a complete archive.
