United States district court

The United States district courts are the general trial courts of the United States federal court system. Both civil and criminal cases are filed in the district court, which is a court of law, equity, and admiralty. There is a United States bankruptcy court associated with each United States district court. Each federal judicial district has at least one courthouse, and many districts have more than one. The formal name of a district court is ``the United States District Court for'' the name of the district--for example, the United States District Court for the Eastern District of Missouri.
