How do state and federal courts differ in the US?

State and federal courts in the U.S. differ primarily in their jurisdiction and the types of cases they handle. State courts deal with the vast majority of legal disputes, including family law, criminal cases, and contracts, while federal courts handle cases that involve federal law, constitutional issues, or disputes between states. Additionally, federal courts typically have limited jurisdiction, meaning they can only hear specific types of cases as defined by federal statutes. The structure of the two court systems also varies, with state courts having their own hierarchies and procedures while federal courts follow rules established by federal law.
