Relevant evidence
Relevant evidence: Under Federal Rule of Evidence 401, evidence is relevant if it has any tendency to make a fact more or less probable than it would be without the evidence, and the fact is of consequence in determining the action.

What relevant evidence means
In practice, you will see relevant evidence in pleadings, motions, orders and court rules. The definition above explains the general meaning. Even so, the meaning can shift with context. Therefore, always read it alongside the rule or document where it appears.
Where relevant evidence comes up
For example, the term appears in these procedures:
- Motion in Limine (Court's authority to manage trials; see Luce v. United States, 469 U.S. 38 (1984)): a pretrial motion asking the court to rule in advance on whether particular evidence may be used at trial.
How to research the term
Start with the primary source. For example, if relevant evidence appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read relevant evidence in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.

Why precise terms matter
Legal words often look like everyday words, but they can carry a precise meaning. Because of that, a small misreading can change how you understand a deadline, a duty or a right. Our glossary keeps each definition short and links it to the procedures where it matters.
