Incorporation Records

About these Records

The Colorado State Archives has many records which document the legal history of businesses, irrigation ditches, road companies, fraternal organizations, churches, and other non-profit associations. Businesses in Colorado’s earliest territorial existence filed their incorporation papers in the county (normally at the County Clerk and Recorder’s office) where their principal place of business was located. In these early years, a corporation could also be established by law through the Territorial Legislature. These incorporations were recorded in the “Private Acts” section of the Colorado Session Laws. From 1861, the Secretary of the Territory (after statehood, the Secretary of State) was responsible for recording incorporations and subsequent legal instruments regarding the status of corporations. Records can thus be found in the Secretary of State's Incorporation Books and in the Legislative Session Laws.
