Courthouse
Douglas County District Court
A Lone Tree personal injury lawsuit is filed in the Douglas County District Court, the state trial court of general jurisdiction, at the Douglas County Courthouse, 4000 Justice Way, Suite 2009, Castle Rock, CO 80109. Douglas County became the seat of Colorado's new 23rd Judicial District, with Elbert and Lincoln counties, when that district opened on January 14, 2025. Local civil procedure differs from other counties, and the judges and opposing counsel either know your firm or they do not. We handle these cases directly.
