How long does a law firm have to keep client files after a matter closes, and who decides what gets destroyed?

There is no single number. How long a law firm keeps a client file after a matter closes depends on the type of matter, the governing jurisdiction, and the firm’s own retention policy. Most firms set a baseline period that runs from the date the matter closes, then extend or shorten it based on the categories of information the file contains.

What drives the retention period

Several overlapping factors determine how long files must be kept:

• Professional responsibility rules. State bar rules generally require firms to safeguard client property and original documents, and to return or preserve files the client may need. These rules rarely state an exact number of years, so firms adopt a defensible default.
• Statutes of limitations. Files are often kept at least until the period for legal malpractice claims and any underlying claims has run, so the firm can defend itself if a dispute arises later.
• Substantive law. Tax, employment, corporate, real property, estate, and minors’ matters frequently carry longer obligations than routine matters.
• Client agreements. Engagement letters may specify who owns the file, how long it is retained, and how it is returned or destroyed.
• Legal holds. Any litigation hold or anticipated dispute suspends destruction entirely until the hold is lifted.

Certain items, such as original wills, trust documents, deeds, and other irreplaceable originals, are commonly kept indefinitely or returned to the client rather than destroyed.

Who decides what gets destroyed

Destruction is a governance decision, not an individual one. A defensible program assigns clear roles:

• A records retention schedule, approved by firm leadership and reviewed by counsel, sets the categories and time periods.
• The responsible attorney confirms the matter is truly closed and no hold applies before any file is eligible.
• A records or information governance function runs disposition on schedule, documents what was destroyed and when, and keeps that destruction log.

The key principle is consistency. Records should be destroyed only under an approved schedule, applied uniformly, and never selectively in the face of a dispute. Recognized standards such as ISO 15489 describe how to build and document this kind of authorized, repeatable disposition process.
