The County Clerk Division of the Clerk-Recorder-Assessor Department has a variety of duties including: issuing marriage licenses, filing Fictitious Business Name Statements, processing notary registrations and bonds, handling environmental documents, and performing civil marriage ceremonies. The County Clerk Division also issues certified copies of marriage, birth and death records on behalf of the County Recorder. Note that Sonoma County will only have records for events that occurred in Sonoma County (someone was born, died or purchased their marriage license in Sonoma County). Visit our website to learn how to obtain certified copies of these documents.
