Land and Property

Land and property records can place an ancestor in a particular location, provide economic information, and reveal family relationships. Land records include: deeds, abstracts and indexes, mortgages, leases, grants and land patents.

See Colorado Land and Property for additional information about early Colorado land grants.

After land was transferred to private ownership, subsequent transactions were usually recorded at the county courthouse, where current records are also housed.
