County and City Records

The California State Archives has some original and microfilm local government records from 28 California counties. Types of records include: Probate (primarily indexes and case files), Courts (County, District, Judicial, and Superior Court case files, judgments, registers, and fee books), Bonds, Letters and Wills, Naturalization, Deeds, Homesteads (may include Homestead declarations and indexes), Birth (may include indexes to births, registers of births, and delayed certificates of births), Death (may include indexes and registers of death), Marriage (may include indexes, and affidavits for marriage licenses), Great Registers (voter registration), Declaration of Intention (related to Naturalization), and Miscellaneous (may include records from the following county offices: Assessor, Clerk/Recorder, Treasurer, and Auditor).

Most of the county records available at the California State Archives are microfilm copies produced by the Genealogical Society of Utah and are also available through local Church of Jesus Christ of Latter–day Saints (LDS) Family History Centers. These records do not always include name indexes. Researchers should also contact or visit the county clerk or recorder's office where the record was filed.
