Irreparable harm
Irreparable harm: Harm that cannot be adequately remedied by money damages after the fact.

What irreparable harm means
Put simply, irreparable harm is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.
Where irreparable harm comes up
For example, the term appears in these procedures:
- Motion for a Temporary Restraining Order (TRO) (Fed. R. Civ. P. 65(b)): an emergency request for a short-term order, sometimes without notice to the other side, to prevent immediate and irreparable harm.
How to research the term
To research irreparable harm, begin with the rule, statute or contract where the word is used. Each one can give it a slightly different meaning. Then compare that text with how courts in your area have applied it. Also check the local rules of your court, since they can add requirements. If your case is in state court, the state rules control. So start with our state procedures guide to find them. In the end, always confirm that the source you rely on is current.
