What is a legal hold?
A legal hold, sometimes called a litigation hold, is a process that preserves documents by freezing them in place so they cannot be altered or deleted while a legal matter, an investigation, or an audit is anticipated or underway.
What it actually means
When an organization reasonably expects litigation or a formal inquiry, it has a duty to preserve the documents that might be relevant. A legal hold is how that duty is carried out. It overrides normal handling: documents under hold are exempt from routine retention schedules and cannot be disposed of, even if their scheduled deletion date arrives, until the hold is lifted.
In a well-run system, placing a hold is a deliberate, controlled action. It identifies the documents to be preserved and locks them, and it is a permission-gated step, so not just anyone can place or lift one.
Why it matters
Failing to preserve documents once litigation is anticipated is called spoliation, and the consequences are serious. Courts can impose sanctions, draw adverse inferences, or worse, and “our retention policy deleted it on schedule” is not a defense if the deletion happened after the duty to preserve arose. A legal hold is the mechanism that prevents that outcome.
The nightmare scenario a legal hold guards against is specific: a routine retention rule quietly disposing of a document you were legally obligated to keep. Without a hold that overrides retention, the two systems can work against each other. With one, preservation always wins.
In practice
A legal hold should be easy to place quickly, freeze the right documents completely, override any retention or disposition, be limited to authorized people, and be fully logged, so you can show exactly what was preserved and when.
