CA Health & Safety Code Section 103435

In lieu of separate proceedings, a single petition may be filed with the superior court to change the petitioner’s name and recognize the change to petitioner’s gender and, if requested, to order the issuance of a new birth certificate. With respect to such a petition, the court shall follow the procedure set forth in Title 8 (commencing with Section 1275) of Part III of the Code of Civil Procedure; however, the order to show cause shall not include the petition to recognize the change of gender. A certified copy of the decree of the court issued pursuant to this section shall, within 30 days, be filed with both the Secretary of State and, if the judgment includes an order for a new birth certificate and if the petitioner was born in this state, the State Registrar. Upon its receipt, the State Registrar shall establish a new birth certificate as provided in this article.
