# E-Discovery (EDRM)
Backlink: [[Domain 1 - Index]]
**Definition:** The Electronic Discovery Reference Model outlines stages for handling electronically stored information (ESI) in legal matters.
## Key Facts
- Stages: Info Governance → Identification → Preservation → Collection → Processing → Review → Analysis → Production → Presentation.
- Legal hold: preserve relevant ESI; suspend normal deletion.
- Scope and proportionality limit burden and cost; protect metadata.
- Cross-border issues require privacy/compliance coordination.
- **Verify:** check official (ISC)² CBK and current exam outline.
