Sonoma County Courthouse and Government Records


Sonoma County Courthouse

Researchers often overlook the advantages of Sonoma County court, probate, and land files as a useful resource of genealogical details. Hidden away in California courthouses and archives everywhere tend to be the dreams and frustrations of the many California inhabitants.

The possibilities are great that your potential forefathers have left a detailed document of at least a number of facets of their lives in the Sonoma County court records. Even if your ancestors is not mentioned in a Court case, contemplate all of the other methods that could have lead to her or him showing up in court records.

Courthouse History - After residents voted to move the county seat from Sonoma to Santa Rosa, Sonoma County built two grand courthouses in the center of the town. The first, completed in 1885, was destroyed in the 1906 earthquake. The second, constructed of locally quarried stone and reinforced with steel and concrete, was "built for all time and the earthquake," according to one local historian. But by the mid-1960s the county was forced to declare the building seismically unsafe and it was demolished. After the courts moved to a new county center, the site was rededicated in 1967 as "Old Courthouse Square."

Some counties encompass land settled in the eighteenth century; their records pre-date county formation. Land transactions and vital records recorded in the county are at the county recorder's office. The county clerk general has probate books and files from the county's superior court, civil court records, and naturalizations. Divorces may be in either place, depending on how filed.
