How should a law firm manage electronic client files and matter records, and how long do you keep them after a case closes?

Law firms hold some of the most sensitive electronic records in any profession: privileged communications, financial data, and personal information tied to specific clients and matters. Managing these well means treating them as a governed information program, not just folders on a shared drive.

Organize Around the Matter

The matter is the natural unit of organization for legal records. Build a consistent structure so every file can be traced to a client and matter:

• Use a stable client/matter numbering scheme that does not change when staff or systems do.
• Apply consistent naming and metadata (matter ID, document type, date, author) so records remain findable years later.
• Capture all formats in one place: email, messaging, documents, scanned originals, and system-generated records.

Consistent metadata and classification are core principles of recognized records management practice, including ISO 15489, which frames records as authentic, reliable, and usable evidence of activity.

Secure and Preserve

Electronic client files require access controls aligned to need-to-know, encryption, and reliable backups. Because privilege and confidentiality attach to these records, audit trails showing who accessed or changed a file are essential. Plan for format obsolescence too: a file you cannot open in ten years is effectively lost.

Retention After a Case Closes

There is no single universal retention period. The right answer depends on:

• Jurisdictional bar rules and professional-responsibility obligations.
• Statutes of limitation and malpractice exposure for the matter type.
• Client agreements and any obligation to return original documents.
• Tax, regulatory, and litigation-hold requirements that can override routine destruction.

A common approach is to define retention by matter type in a written schedule, start the clock at formal matter closure, and dispose of records only after the longest applicable obligation expires. Never destroy records subject to a litigation hold. When destruction does occur, do it defensibly: document what was destroyed, when, and under what authority. The Sedona Conference offers widely cited guidance on defensible disposition and e-discovery considerations.

The safest practice is to confirm specific periods with your jurisdiction’s bar rules and counsel rather than relying on a generic number.
