How to Search Sonoma County Records (Start Here)
Sonoma County combines the Clerk, Recorder, and Assessor into a single office — the Clerk-Recorder-Assessor. This means property assessments, recorded documents, marriage licenses, and business filings all come from one department.
- Sonoma Superior Court's Case Portal at sonoma.courts.ca.gov — a recently updated web-based system replacing the old database. Covers civil, criminal, family, probate, and traffic.
- Recorded documents (deeds, liens, mortgages): The Clerk-Recorder-Assessor offers an online index of official records from 1964 to present at sonomacounty.gov/clerk-recorder-assessor.
- Property assessments: Same office — the Assessor function is part of the Clerk-Recorder-Assessor.
- Marriage licenses and business filings: Also through the Clerk-Recorder-Assessor. Fictitious business names and professional registrations are searchable online.
- No free statewide criminal search in California. Live Scan through CA DOJ for full background.
