Clayton, Missouri

Legal resources in Clayton.

Clayton is the seat of St. Louis County and the county's legal, financial, and professional center. The city anchors the 21st Judicial Circuit Court at the St. Louis County Courthouse and hosts major corporate headquarters, professional services firms, and the deep suburban St. Louis metro bar. Clayton is legally distinct from (and immediately west of) the independent City of St. Louis — with both jurisdictions operating separate court systems.
