Preserving evidence is a core obligation in litigation, and today most of that evidence exists as electronically stored information (ESI). Because digital data is far more fragile than physical records, legal teams must understand how to identify, prevent, and defend against digital spoliation.

Key Takeaways

• Digital spoliation occurs when relevant ESI is lost, altered, or destroyed after the duty to preserve has been triggered.
• Courts may impose sanctions if spoliation prejudices the opposing party or was done intentionally.
• Well‑implemented legal holds are the strongest safeguard against unintentional data loss.
• Documented preservation workflows help demonstrate reasonable efforts and strengthen defensibility.

What Is Digital Spoliation?

Digital spoliation involves the destruction or alteration of ESI that should have been preserved for litigation. This can happen intentionally—such as deleting damaging emails—or inadvertently through routine processes like auto‑delete settings or failed communication of legal holds.

Why Spoliation Matters

Lost ESI can severely disadvantage the opposing party and undermine the integrity of the judicial process. Courts distinguish between negligent loss and intentional destruction, with consequences varying based on a party’s intent and the resulting prejudice.

How Rule 37(e) Applies

Rule 37(e) of the Federal Rules of Civil Procedure governs how courts respond when ESI is lost due to unreasonable preservation efforts. Judges first assess whether the information can be recovered. If not:

• Unintentional loss may lead to corrective steps if the opposing party is prejudiced.
• Intentional destruction can trigger severe sanctions, including adverse inference instructions, case dismissal, or default judgment.

Intentional vs. Negligent Spoliation

Intentional spoliation involves deliberate efforts to conceal evidence.
Negligent spoliation often stems from oversight, such as failing to disable automatic deletion settings or miscommunicating preservation duties.

Both forms can result in sanctions if the loss harms the opposing party.

How Digital Spoliation Happens

Digital data can disappear through routine system maintenance, retention policies, overwritten backups, or user error. Without a clear legal hold, custodians may unknowingly delete or modify relevant information before preservation protocols take effect.

When the Duty to Preserve Begins

The obligation to preserve ESI begins when litigation is reasonably anticipated—not when a subpoena arrives. Common triggers include regulatory inquiries, government communications, or internal notice of potential disputes.

Potential Consequences

Depending on severity, courts may issue:

• Adverse inference instructions
• Monetary penalties
• Case‑dispositive sanctions
• Referrals for criminal investigation in extreme cases

How Legal Teams Can Prevent Spoliation

Move Quickly on Legal Holds

Issuing a prompt legal hold ensures custodians stop manual deletion and overrides automated processes. A strong hold system keeps relevant ESI intact across large environments.

Coordinate with IT

Legal and IT must collaborate to:

• Suspend automated retention and cleanup policies
• Maintain technical documentation of all preservation steps

Preserve All Relevant ESI

Identify and prioritize data sources early—email, cloud platforms, shared drives, mobile data, chat applications, and social media—to ensure comprehensive preservation before collection begins.

A defensible, repeatable process is the best safeguard against spoliation claims and the sanctions that may follow.
