Colorado Land Records
From Ancestry.com Wiki
Colorado is a Public-Domain State.
Records of the Spanish and Mexican land grants are located in the Denver Public Library Western History and Genealogy Department. Once the area fell under U.S. jurisdiction, land was transferred from the federal government to individuals. The Homestead Act of 1862, along with other federal statutes, provided for the disposal of most of Colorado’s land.
Land offices existed in Central City, Del Norte, Denver/Golden City, Durango, Glenwood Springs, Gunnison, Hugo, Lamar, Leadville/Fairplay, Montrose/Lake City, Pueblo, Akron, and Sterling. Some early land records of Denver were lost to floods, while others have survived. The Homestead Tract Books and Register of Homestead Entries are found at the National Archives—Rocky Mountain Region in Denver. While some early land records of Denver were lost in the Cherry Creek flood of 1864, others have survived. The patent case files are located at the National Archives, Washington, D.C. The researcher must know the legal description of the land of interest.
Once granted, transactions of land are recorded at the county level in deed books. These land records, including mortgages and land plats, are the responsibility of the county clerk and recorder’s office. In some cases, indexes are found in a different location from the files.
