Superior Court Records

At statehood (1889), the Washington State Constitution created the state judicial system and designated the trial court of general and unlimited jurisdiction as the Superior Court. In King County it succeeded the federal Third Territorial District Court (1853-1889).

In general, Superior Court records are considered permanent and are retained by the court. To access most Superior Court indexes and case files 1854-present, please contact the Superior Court Clerk at 206-296-9300 (dial "9" to speak to a person) or

Some historical Superior Court records and indexes are held by other agencies.  Please review the lists below:

The following records are held by the King County Archives:

  • Index of Licenses of Physicians, Optometrists, Chiropodists and Midwives, 1890-1980
    This series contains an index to medical and professional licenses issued by the state and presented to the county clerk (Superior Court clerk) for registration as a prerequisite to practice in King County. These records show the name of the licensee, nature of the license, license number, date of issue, date of filing, whether an original, certified copy or a renewal, and volume and page number if that information was recorded. These records are arranged alphabetically by surname of licensee.

  • Juvenile Court annual reports, 1911-1974
    Washington's superior courts were granted original jurisdiction over all juvenile cases in 1905. This series is composed of annual narrative and statistical reports of the programs and activities of King County's juvenile court from 1911 to 1974. During this period, activities of the court included both its legal functions and its social work with delinquent and dependent youth and their families. Early reports (1911-1930) stress the court's social work by including special reports and commentaries on causative pathologies, case studies, and parental and governmental responsibilities to youth. A separate report section documented activities of the Mothers' Pension Department (1913-1937), which dispersed cash and material assistance to female-headed families with dependent children prior to the federalization of this program. Reports from this period are frequently illustrated with photographs of court and custodial facilities, building plans (1915) and personnel. No reports were apparently printed for the years 1931-1935, but statistical summaries for this period are present. Between 1936 and 1958, reports primarily consisted of tabulated statistics. In the 1940s, data for several years were sometimes combined into one report; no report was published for 1953. Beginning in 1959, court statistics were again accompanied by narrative commentary, and sometimes by photographs and graphics. The expansion of the Youth Service Center in Seattle's Central Area and the role of the Juvenile Court in the relocation of neighborhood residents are reflected in reports from the 1960s. The court's social work programs were largely transferred to County Executive departments after 1974.

District Court


Justice courts were created by the Oregon Organic Act of 1848, and were incorporated into the county judicial structure when King County was created in 1852. The Washington State Justice Court Act of 1961 combined the name and activities of the Justice Court with the District Court. In 1962, King County adopted this change through Commissioners' Resolution 24130.
