Donation Land Claims Index and Maps (1861-1882)

Under the Oregon Donation Land Claims Act of 1850, Congress allowed 320 acres of land in Western territories to be claimed by a single person and 640 acres by a married couple. The claimants received final title to their land when they had lived on it for four years and made certain improvements, or when they purchased their land in lieu of fulfilling residency requirements. Records include a name index to Donation Land Claim owners, as well as legal descriptions and maps of land claims.

Land Office Correspondence (1879-1887)

This series includes correspondence between the Clerk of the Territorial District Court in Seattle and the U.S. Land Office in Olympia. Usually, the correspondence pertains to incomplete homestead applications. Most of these applicants were instructed to provide signatures, proofs of naturalization, fees or other application requirements. Some letters from homesteaders to the Land Office are included. The correspondence generally includes information such as the names of the land owners, the date their land was settled or a legal description of the property. Other valuable information is sometimes included including a description of the family (spouse and number of children), occupation(s) of land owners, land improvements and/or building descriptions. Although this series dates from 1879, most of the correspondence is from 1884-1887.

*Definition: The Torrens Title Act (adopted in Washington State in 1907) provides an alternate method for establishing title to property. It differs from traditional recording systems in that the state guarantees the owner's title. Under the Torrens System, state courts approve an examination of a parcel's title history and ultimately issue a Certificate of Title to the owner. The certificate is then registered with the county auditor or recording office.

Remarks usually state the date the property deed was received or recorded by King County.
