Make checks payable to San Mateo County Clerk-Recorder.
Processing time may take several days. Please expect to receive your copies via regular mail in approximately two weeks. If you wish to expedite your request you may choose to send it via overnight mail. If so, please include a pre-paid overnight return envelope along with your notarized application and check or money order. Certificates from the years 1865 to 1965 may require an additional two days for processing.
Common examples of situations requiring a birth certificate amendment include: change of paternity, adoption, court-ordered name change, or gender reassignment, among others. The final approval and registration of all amendments must be completed by the State Office of Vital Records. However, our office can perform the preliminary review of an application to amend a recently issued certificate (less than 3 months) that has not yet been registered by the state office. You can call us to check that status. After state review and approval of the application, all new, amended certificates originate from the state office, after about two months of processing time. The state will provide our office with a copy of the amended certificate for our local files.
