The United States district courts are the general trial courts of the United States federal judiciary. Both civil and criminal cases are filed in the district court, which is a court of law, equity, and admiralty. There is at least one judicial district for each state, the District of Columbia, and Puerto Rico. The territories (insular areas) of Guam, the Northern Mariana Islands, and the United States Virgin Islands each have one territorial court; these courts are called “district courts” and exercise the same jurisdiction as district courts.
