What is a Litigation Hold? Why Preserving Emails Can Make or Break a Lawsuit

Every organization creates thousands of digital records each day. Emails, documents, chat conversations, spreadsheets, and calendars often become valuable evidence when a legal dispute arises. If this information is deleted after a company expects litigation, the consequences can be severe.

That is why businesses implement a litigation hold. Understanding What is a Litigation Hold helps organizations protect critical evidence, comply with legal obligations, and reduce the risk of court sanctions.

Understanding a Litigation Hold

A litigation hold, also known as a legal hold, is a formal instruction that requires employees and IT teams to preserve information that may be relevant to an ongoing or anticipated legal matter. Once the hold is issued, routine deletion or modification of the identified data must immediately stop.

The preserved information is commonly referred to as Electronically Stored Information (ESI), which may include:

• Business emails

• Office documents

• Chat messages

• Calendar events

• Shared files

• Digital records

The purpose is simple: ensure that potential evidence remains complete and available throughout the legal process.

When Does a Litigation Hold Become Necessary?

A litigation hold should begin as soon as litigation is reasonably anticipated. Companies do not have to wait until a lawsuit is officially filed.

Common situations that trigger a hold include:

• A customer threatens legal action.

• An employee files a workplace complaint.

• A government agency begins an investigation.

• A contract dispute escalates.

• A regulatory inquiry requests business records.

Delaying preservation after these events can expose an organization to allegations of evidence destruction.

Who Is Responsible?

The legal department or external legal counsel generally initiates the litigation hold. They identify employees who may possess relevant information, often referred to as custodians.

Custodians can include:

• Executives

• Human Resources personnel

• Finance teams

• Sales representatives

• IT administrators

• Former employees who still possess company information

Each custodian must preserve the data under their control until the hold is formally lifted.

What Does a Litigation Hold Notice Contain?

A litigation hold notice is the official communication sent to custodians. It explains their legal responsibilities and outlines the information that must be preserved.

A typical notice includes:

• Description of the legal matter

• Types of records to preserve

• Date range of relevant information

• Instructions to stop deleting data

• Contact details for legal counsel

• Requirement to acknowledge receipt

The notice should be written clearly so every recipient understands what actions are required.

The Litigation Hold Process

A successful litigation hold generally follows these steps:

Identify the legal trigger

Legal counsel determines that a dispute is likely and authorizes preservation.

Locate custodians and data sources

Relevant users, mailboxes, file shares, cloud storage, and backup locations are identified.

Issue preservation notices

Formal instructions are distributed to all affected custodians.

Suspend deletion policies

Automatic retention schedules, mailbox cleanup rules, and document deletion processes are paused for affected data.

Preserve evidence

Data is collected and stored using defensible methods while maintaining proper documentation and chain of custody.

Monitor compliance

Legal teams periodically remind custodians of their responsibilities until the matter concludes.

Release the hold

After the legal matter is completely resolved, legal counsel issues a formal release and normal retention policies resume.

Why Email Preservation Matters

Emails frequently become one of the most requested forms of evidence during investigations and civil litigation because they document conversations, approvals, timelines, and business decisions.

Improper handling of email evidence can result in:

• Court sanctions

• Financial penalties

• Loss of credibility

• Negative inferences against the organization

• Increased litigation costs

Organizations should ensure email evidence remains authentic and unchanged throughout the preservation process.

Best Practices for Organizations

Businesses can strengthen their legal readiness by following several best practices:

• Create a documented litigation hold policy.

• Train employees on preservation responsibilities.

• Coordinate closely between legal and IT teams.

• Maintain detailed audit records.

• Verify that preservation methods are legally defensible.

• Regularly review active litigation holds.

Many organizations also rely on dedicated Email forensics software to preserve, search, and analyze email evidence while maintaining forensic integrity across multiple email platforms.

Conclusion

A litigation hold is much more than an internal notification. It is a legal safeguard that protects potentially relevant evidence from accidental or intentional deletion. Acting promptly, notifying the right custodians, and preserving digital information correctly helps organizations remain compliant and better prepared for legal proceedings.

Implementing a well-defined litigation hold process significantly reduces legal risk while ensuring valuable electronic evidence remains available whenever it is needed.
