Territorial courts are specialized courts in the United States that handle legal matters in U.S. territories, such as Puerto Rico, Guam, and the U.S. Virgin Islands. These courts have jurisdiction over both civil and criminal cases, similar to state courts, but their authority is derived from federal law. The judges in territorial courts are appointed by the President of the United States and confirmed by the Senate. These courts play a crucial role in ensuring that residents of U.S. territories have access to a judicial system that addresses their unique legal needs and circumstances.
