Authentication of San Francisco Notary Signature

The Office of the County Clerk is currently closed to the public to prevent the spread of COVID-19. For available services, application information and processing times, go to County Clerk Services During COVID-19 Response.

If sending a notarized document overseas, some countries require documents to receive an “apostille” from the Secretary of State’s Office. However, unless you are sending the document directly to Sacramento to their Notary Division, you would be required to get an authentication of the notary before the Secretary of State’s, regional offices, can perform this service. 

The authentication of the notary can be done by the County Clerk’s office in the county in which the notary is commissioned. Only documents containing a jurat or an acknowledgment may be authenticated. Please note the new provisions of Civil Code Section 1189 beginning January 1, 2015, on a jurat and acknowledgment. The county in which the notary is commissioned is indicated on the notary’s stamp.

Please note that you could skip the steps outlined below if you choose to mail the documents directly to the Secretary of State's Office in Sacramento, CA.  Their process takes about 1-2 weeks. 

To obtain authentication of a San Francisco commissioned notary through the County Clerk’s Office:


1. Come in person (can be 3rd party) or mail to us the notarized document.


Our address is:

S.F. County Clerk

1 Dr. Carlton B. Goodlett Place

City Hall, Room 168

San Francisco, CA 94102-4678


2. Include payment of $15.00 for each authentication (even if it is the same notary). 


In-Person: Only cash, money order, or preprinted personal check (from a U.S.A. issued bank, no foreign checks) payable to S.F. County Clerk,  or debit/credit card are acceptable. 


By Mail: Only money order or preprinted personal check (from a U.S.A. issued bank, no foreign checks) payable to S.F. County Clerk.  Must also include a self-addressed stamped envelope so that we can return the authenticated notarized document(s) back to you.


Once you have received the authentication from our office, you can then proceed with the “apostille” process with the Secretary of State’s Office.  For information or questions on that process, please visit their website at
