Which courts have jurisdiction over cases involving what?

Jurisdiction over cases varies by the type of legal matter and the level of court. Generally, state courts handle most cases, including family law, criminal cases, and contract disputes, while federal courts have jurisdiction over cases involving federal law, disputes between states, and matters involving diverse citizenship exceeding a certain monetary threshold. Specialized courts, such as bankruptcy or tax courts, address specific legal issues. Ultimately, the appropriate court depends on the nature of the case and the laws applicable to it.
