In early dispute stages, two related but distinct concepts frequently arise: the litigation hold and digital evidence preservation. Although both are intended to prevent loss of relevant information, they serve different functions and typically occur at different procedural layers.

Litigation hold: a legal directive

A litigation hold is generally a legal instruction to preserve potentially relevant information once a dispute becomes reasonably foreseeable. It commonly addresses document retention, suspension of deletion practices, and organizational communication regarding preservation obligations.

Digital evidence preservation: a technical process

Digital evidence preservation focuses on stabilizing specific devices, accounts, or data sources through defensible acquisition, documented handling, and protection against alteration or loss. These activities are technical in nature and distinct from legal decision-making or interpretation.

Key distinctions in function

Litigation hold defines preservation responsibility at the legal or organizational level.
Digital Evidence preservation applies technical measures to stabilize specific devices, accounts, or data sources.
A Litigation hold may exist without immediate technical collection.
Technical preservation may occur before or after formal legal directives.

Timing considerations

Litigation holds are typically guided by counsel and tied to the foreseeability of litigation. Technical preservation timing depends on factors such as ongoing device use, automated deletion risk, and potential evidence volatility.

Why the distinction matters

Confusion between these roles may delay stabilization of relevant digital information or create the assumption that legal notice alone prevents data change. Recognizing the separate functions supports clearer coordination between legal direction and technical preservation activities

Litigation Hold vs. Preservation (at a glance)

Aspect	Litigation Hold	Digital Evidence Preservation
Primary nature	Legal directive	Technical process
Trigger	Dispute becomes reasonably foreseeable	Risk of alteration, loss, or volatility in defined sources
Core purpose	Prevent deletion and preserve information broadly	Stabilize specific devices, accounts, or datasets with defensible handling
Typical activities	Retention instructions, deletion suspension, custodial communication	Read-only acquisition where appropriate, handling documentation, integrity protection
Scope	Organization-wide and/or custodial	Targeted to defined evidence sources and authorizations
Outputs	Compliance actions and retained records	Preserved materials with traceability documentation (and integrity artifacts where appropriate)
Relationship to analysis	Supports discovery and legal review	Enables later independent legal or expert review

Frequently asked questions

Is this legal advice?

No. This page is informational only. Data365 Evidence is not a law firm and does not provide legal advice or litigation strategy.

Does preservation replace digital forensics?

No. Preservation stabilizes and documents evidence sources. Forensic analysis involves technical interpretation and opinion, and is separate unless independently retained.

What should be documented at the preservation stage?

At minimum: authorization and scope, handling notes, custody/transfer traceability, and integrity verification artifacts where appropriate.
