CA Health & Safety Code Section 103430

(a)

The petition shall be accompanied by an affidavit of a physician attesting that the person has undergone clinically appropriate treatment for the purpose of gender transition, based on contemporary medical standards, and a certified copy of the court order changing the applicant’s name, if applicable. The physician’s affidavit shall be accepted as conclusive proof of gender change if it contains substantially the following language: “I, (physician’s full name), (physician’s medical license or certificate number), am a licensed physician in (jurisdiction). I attest that (name of petitioner) has undergone clinically appropriate treatment for the purpose of gender transition to (male or female). I declare that the foregoing is true and correct to the best of my knowledge.”

(b)

The petition shall be heard at the time appointed by the court. At the hearing, the court may examine on oath the petitioner, and any other person having knowledge of facts relevant to the application. At the conclusion of the hearing the court shall grant the petition if the court determines that the physician’s affidavit shows that the person has undergone clinically appropriate treatment for the purpose of gender transition.

(c)

If the judgment includes an order for a new birth certificate and if the petitioner was born in this state, a certified copy of the decree of the court ordering the new birth certificate, shall, within 30 days from the date of the decree, be filed with the State Registrar. Upon receipt thereof together with the fee prescribed by Section 103725, the State Registrar shall establish a new birth certificate for the applicant.

(d)

The new birth certificate shall indicate the sex of the registrant as specified in the judgment of the court and shall reflect any change of name specified in the application if accompanied by a court order, as prescribed by Section 103425. No reference shall be made in the new birth certificate, nor shall its form in any way indicate, that it is not the original birth certificate of the registrant.
