The county is under the jurisdiction of the 37th District Court, a state district court. State district courts in Arkansas are courts of original jurisdiction for criminal, civil (up to $25,000), small claims, and traffic matters. State district courts are presided over by a full-time District Judge elected to a four-year term by a districtwide election. The judge presides over both the Texarkana Department at 100 North State Line Avenue in Texarkana and the Miller County Department at the Miller County Correctional Facility at 2300 East Street.
