At Orange County Apostille, we work with official government documents every day—including vital records such as birth certificates, marriage certificates, death records, and public documents issued by county officials. When it comes to Contra Costa County, one name consistently comes up on certified vital records: Debi Cooper, the County Clerk-Recorder and Registrar of Voters.

Whether you’re looking to apostille a birth certificate issued in Concord, a marriage certificate recorded in Walnut Creek, or a death certificate from Richmond, chances are it bears the signature or certification of Debi Cooper. Here’s what you need to know about her role and why her name matters when it comes to apostille services.

Who Is Debi Cooper?

Debi Cooper currently serves as the Clerk-Recorder and Registrar of Voters for Contra Costa County, a position she was appointed to in 2019 following the resignation of former Clerk-Recorder Joe Canciamilla.

Debi Cooper brought over 30 years of experience in both the public and private sectors before taking on this critical role. She has a strong background in document management, public records law, and election administration, which makes her uniquely qualified to serve the nearly 1.2 million residents of Contra Costa County.

Under her leadership, the Clerk-Recorder’s office has:

Modernized records processing systems
Ensured transparent and fair election administration
Streamlined the issuance and certification of vital records
Maintained compliance with state and federal regulations related to public records

Why Her Signature Matters for Apostilles

When you request an apostille for a California document, the California Secretary of State will verify the signature of the official who signed or certified the document. In Contra Costa County, that official is often Debi Cooper.

Documents that commonly bear her signature include:

Certified birth certificates
Certified marriage certificates
Certified death certificates
Certified property documents

Because Debi Cooper is a recognized and authorized official, documents she certifies are valid for apostille processing. Our team at Orange County Apostille ensures that each document is reviewed to confirm the signature and seal are acceptable for California Secretary of State authentication.
