In the United States, sentencing law varies by jurisdiction. The jurisdictions in the US legal system are federal, state, regional, and county. Each jurisdictional entity has governmental bodies that create common, statutory, and regulatory law, although some legal issues are handled more often at the federal level, while other issues are the domain of the states. Civil rights, immigration, interstate commerce, and constitutional issues are subject to federal jurisdiction. Issues such as domestic relations, which includes domestic violence; marriage and divorce; corporations; property; contracts; and criminal laws are generally governed by states, unless there is federal preemption.
