Courthouse
Jefferson Combined Court, First Judicial District
Most of Arvada sits in Jefferson County, where civil suits above the county-court limit are filed in the Jefferson Combined Court at 100 Jefferson County Parkway, Golden, CO 80401. The main court line is 720-772-2500.
A smaller part of Arvada extends into Adams County. Crashes there are filed in the Adams County District Court, Seventeenth Judicial District, at 1100 Judicial Center Drive, Brighton, CO 80601. The county where the crash happened controls, so two crashes a few blocks apart can end up in two different courthouses.
