The California Secretary of State provides authentication of public official signatures on documents to be used outside the USA. The country of destination determines whether the authentication is an Apostille or Certification.

Apostilles and Certifications only certify to the authenticity of the signature of the official who signed the document, the capacity in which that official acted, and when appropriate, the identity of the seal or stamp which the document bears. The Apostille or Certification does not validate the contents of the document.

The California Secretary of State authenticates signatures only on documents issues in the State of California signed by a notary public or the following public officials and their deputies:

  • Executive Clerks of the Superior Court
  • Officers whose authority is not limited to any particular county
