Online Access Options

California's judicial branch offers digital probate resources through its dedicated portal: courts.ca.gov/probategenealogy-contra-costa.htm. This site provides case search functionality, procedural guides, and genealogical research assistance specific to Contra Costa County.

Practical Search Tips

• Case numbers accelerate retrieval—obtain these from family members or prior correspondence
• Wills become public only after probate filing—living persons' wills remain private
• Older records (pre-1980s) may require microfilm requests or archival retrieval
• Certified copies require formal request and fees; plain copies may suffice for research

Alternative Resources

The Contra Costa County Law Library in Martinez offers public access to legal databases and research assistance. For complex searches, probate attorneys or professional genealogists familiar with local procedures can expedite the process.

Remember: probate records document court-supervised estate administration. Not all wills undergo probate (e.g., those with living trusts or small estates), so absence from court records doesn't confirm a will's nonexistence.
