South Dakota Court Records

All guardianship, estate settlement, and probate matters were originally handled by the county courts in South Dakota. Those courts also handled some criminal and civil matters. Some of the depositions from criminal and civil cases were held by circuit courts, though. So were judgments, case files, juror lists, and naturalization records.

A unified judicial system was not created in South Dakota until November of 1972. At that time, judges became state supreme court judges or circuit court judges. District and county courts were eliminated. The Clerk of the Court in each county was often left with the records from those old court systems. However, some of the records have been moved to the South Dakota State Archives. The criminal dockets for several counties are also located there. Those counties are:

Beadle County (1919-1923), Jones, County (1919-1939), Mellette County (1912-1957), Minnehaha, County (1890-1896, 1923-1973), with Police Dockets (1884-1909). See Also Research In Court Records.

However, the Cultural Heritage Center is home to the State Archives and many of those records have been transferred to that location. They are organized by Unified Judicial System, Circuit Court, and Division of County.

The FHL has several records of Indian agency probate matters on file on microfilm. Others are available at the National Archives. See Also Guide to U.S. Probate Records Research

However, they do contain a lot of useful information, including juror selection information, personal and real property taxes, and docket books. The following tax records can also be found at the archives: Beadle County (1883-1902), Edmunds (1887-1924), Roberts, (1884-1929), Stanley (1891-1930), Union (1870-1901).
