Jurisdiction
Jurisdiction: A court's power to hear a case and make binding decisions.

What jurisdiction means
In practice, you will see jurisdiction 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 jurisdiction comes up
For example, the term appears in these procedures:
- Motion to Dismiss for Lack of Subject-Matter Jurisdiction (Fed. R. Civ. P. 12(b)(1)): a motion arguing the court has no power to hear this type of case.
- Motion to Dismiss for Lack of Personal Jurisdiction (Fed. R. Civ. P. 12(b)(2)): a motion arguing the court has no authority over the defendant.
How to research the term
First, read the term where it actually appears. A rule, statute or court decision may define it for its own purposes. Next, check whether your court has a local rule that uses jurisdiction in a special way. Then look at recent decisions from courts in your jurisdiction. They show how judges apply the term today. Also, remember that state law can differ from federal law. For that reason, use our state procedures guide to find your state’s rules. Finally, confirm every source is current before you rely on it.

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.
