Frequently Asked Questions
What is jurisdiction?
Jurisdiction is the authority of a court to hear and decide a particular case, and more broadly the reach of a particular body of law.

Why does jurisdiction matter?
Jurisdiction matters because it determines which court can decide a case and which laws apply.

What determines a court's jurisdiction?
A court's jurisdiction depends on factors that determine whether it has authority over a particular case, such as the subject matter of the case (whether the court can hear that type of matter) and the parties or location involved. These jurisdictional rules are complex and vary. Whether a particular court has jurisdiction over a specific case is a legal question that depends on these factors and the applicable rules.
How does jurisdiction relate to which laws apply?
In its broader sense, jurisdiction refers to which body of law reaches a particular situation. Because the United States has multiple levels of law (federal, state, local) and many territories (different states and localities), each with its own body of law, jurisdiction determines which of these applies to a situation. This is why the applicable law depends on jurisdiction, and why laws vary across jurisdictions.
Why do laws vary by jurisdiction?
Laws vary by jurisdiction because the United States has multiple levels and territories of law — federal, state, and local — each with its own body of law, and states and localities differ in their specific laws. Jurisdiction determines which of these applies to a situation. This structure means the specific court and law governing a matter depend on the jurisdiction, which is why legal specifics vary and require jurisdiction-specific guidance.
How do you know which jurisdiction applies to a situation?
Determining which jurisdiction applies — which court has authority and which law governs — depends on the specific facts, such as the subject matter, the parties, and the location, and on complex jurisdictional rules. This is a legal question that generally requires a qualified attorney to assess for a specific situation. General understanding of jurisdiction helps you recognize why the applicable court and law depend on the situation, but the specific determination requires professional guidance.
