State Court Records

Wyoming Court Records

In 1868, the Wyoming judicial system was established. At that time, the supreme court was created and it functioned as an appeals court. The supreme court could try cases in any of Wyoming’s 3 districts at the time. As of 1869, women gained the right to vote in Wyoming Territory, which also meant that they could serve as court jury members. After Wyoming gained its statehood, three major state courts were established. They were the state supreme court, the district courts, and the justice of the peace courts. Justice of the peace courts handled misdemeanors and minor cases countywide. District courts also functioned countywide, but they were responsible for probate matters, as well as more serious criminal and civil cases. They also heard a few appeals from justice of the peace courts. The state supreme court heard appeals from the lower courts.

The local courthouses and the Wyoming State Archives hold most of the court records for the state of Wyoming. See Also Research In Court Records.


State Land Records

Wyoming Land Records

Some Wyoming land records go back as far as 1841. However, most land records were not recorded on the county level until after 1869. The first Wyoming land office opened in 1870 in Cheyenne. Soon, the following land offices were also opened: Evanston (1877), Buffalo (1888), Douglas (1890), Lander (1890), Sundance (1890).

Each of those land offices kept homestead entry certificates, desert-land final certificates, timber-culture final certificates, canceled versions of each of those certificates, and other records, including records relating to stone and timber lands.

The National Archives-Rocky Mountain Region has a complete inventory of records that were kept by the Bureau of Land Management (BLM). It is listed in Eileen Bolger, Preliminary Inventory of the Records of the Bureau of Land Management-Wyoming. Those records were kept by 6 Wyoming land offices and consisted of land claims, rights, and patents. The Wyoming State Office of the BLM holds the original patents for land and grantee records. The BLM website also has an index of patented land.

Generally, county land records were not kept prior to 1869. The Wyoming State Archives has land transaction records on file for the years 1869 to 1970. It also holds the records for homesteads that were not patented. County courthouses hold most of the later land records for each county. See Also Guide to U.S. Land Records Research

Assessment Rolls, Inventory, Appraisals of Personal and Real Property
