  • 🟦 Use final vs. draft naming conventions (_v3_FINAL)
  • 🟦 Limit access for sealed, juvenile, or sensitive materials

🕵️How to Organize Discovery Documents

Discovery 

  • ├─ Incoming
  • ├─ From_Opposing_Counsel

Legal Document Numbering: Best Practices for Consistency & Compliance

Proper law firm document numbering  is essential for keeping legal files organized, ensuring audit-readiness, and preventing version confusion across teams. A standardized numbering format also improves retrieval speed, especially in high-volume practices or during litigation prep.

Recommended Numbering Format

Use a consistent, structured format like this:

[Year]-[Client/Matter ID]-[Document Type]-[Sequential Number].pdf

Example:
2025-JD-TRUST-AGREEMENT-003.pdf

This format allows:

  • Chronological sorting
  • Matter-level organization
  • Quick identification by document type
  • Built-in version tracking
