  • Built-in security & compliance (Microsoft Purview, Sensitivity Labels, Retention Policies)

Core Design Principles

Centralized Matter Repository

Each matter should have a single location for storing documents, emails, notes, and tasks. Options include SharePoint sites, libraries, document sets, or Teams channels.

Security & Compliance

Use Microsoft Purview to enforce ethical walls, audit trails, data retention, and access controls to maintain confidentiality.

Microsoft Teams setup with channels per legal matter under practice area

Metadata-Driven Search

Design metadata fields such as:

  • Matter Number
  • Client Name
  • Practice Area
  • Status (Open, Closed)
  • Assigned Attorney

This enables advanced filtering, eDiscovery, and automation.

Seamless UX

Let attorneys work where they’re comfortable—Outlook, Word, Teams—while SharePoint and automation handle structure behind the scenes.

Structuring Your Legal Matter Repository

Choose a structure that balances usability, metadata, and scalability.

Structure Metadata Support Automation Archiving Ease Best For
SharePoint Site per Matter ✅ High ✅ Full ✅ Easy Large/complex matters
Document Set per Matter ✅ High ✅ Full ✅ Easy Medium/large firms
Library per Matter ⚠️ Moderate ⚠️ Partial ⚠️ Medium Corporate departments
Folder per Matter ❌ Low ❌ Minimal ❌ Basic Small firms/beginners
Teams: Practice Area = Team, Matter = Channel ✅ Moderate-High ✅ Full ⚠️ Medium Collaboration-heavy firms
Pro Tip: For the best of both worlds, use Teams channels linked to SharePoint document sets with metadata applied at the set level.
