Colorado Land and Property

Spanish and Mexican Grants
The first land grants in Colorado were given by Spain and Mexico. When the United States acquired the area in 1848, it agreed to recognize these claims. The claims were processed by the U.S. Surveyor General from 1855 to 1890. Some claims processed in the New Mexico office before 1862 relate to land that is now in Colorado.

Federal and State Records
When the United States acquired Colorado, most of the land was unclaimed and became part of the public domain. The federal government transferred land to private ownership through land offices in a process called land entry. The first general land office in Colorado was established in 1863 near Denver. Most of the land office records are at the National Archives—Rocky Mountain Region (Denver). Land entry cases are at the National Archives. Patents and copies of tract books and township plats are at:

County Records
After land was transferred to private ownership, subsequent transactions have been recorded in county offices. The Family History Library has not microfilmed deeds or other property records that are available in each county. You may obtain copies by writing to the county clerk at the county courthouse.
