Burden of proof
Burden of proof: The obligation to prove a fact or claim to the required standard.

What burden of proof means
Put simply, burden of proof 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 burden of proof comes up
For example, the term appears in these procedures:
- Motion for Summary Judgment (Fed. R. Civ. P. 56): a motion asserting there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.
How to research the term
To research burden of proof, 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.
