CCP §1279.5: (a) Except as provided in subdivision (e) or (f), this title does not abrogate the common law right of a person to change his or her name.

(a) Except as provided in subdivision (e) or (f), this title does not abrogate the common law right of a person to change his or her name. (b) A person under the jurisdiction of the Department of Corrections and Rehabilitation or sentenced to county jail has the right to petition the court to obtain a name or gender change pursuant to this title or Article 7 (commencing with Section 103425) of Chapter 11 of Part 1 of Division 102 of the Health and Safety Code. (c) A person under the jurisdiction of the Department of Corrections and Rehabilitation shall provide a copy of the petition for a name change to the department, in a manner prescribed by the department, at the time the petition is filed. A person sentenced to county jail shall provide a copy of the petition for name change to the sheriff’s department, in a manner prescribed by the department, at the time the petition is filed. (d) In all documentation of a person under the jurisdiction of the Department of Corrections and Rehabilitation or imprisoned within a county jail, the new name of a person who obtains a name change shall be used, and prior names shall be listed as an alias. (e) Notwithstanding any other law, a court shall deny a petition for a name change pursuant to this title made by a person who is required to register as a sex offender under Section 290 of the Penal Code, unless the court determines that it is in the best interest of justice to grant the petition and that doing so will not adversely affect the public safety. If a petition for a name change is granted for an individual required to register as a sex offender, the individual shall, within five working days, notify the chief of police of the city in which he or she is domiciled, or the sheriff of the county if he or she is domiciled in an unincorporated area, and additionally with the chief of police of a campus of a University of California or California State University if he or she is domiciled upon the campus or in any of its facilities. (f) For the purpose of this section, the court shall use the California Law Enforcement Telecommunications System (CLETS) and Criminal Justice Information System (CJIS) to determine whether or not an applicant for a name change is required to register as a sex offender pursuant to Section 290 of the Penal Code. Each person applying for a name change shall declare under penalty of perjury that he or she is not required to register as a sex offender pursuant to Section 290 of the Penal Code. If a court is not equipped with CLETS or CJIS, the clerk of the court shall contact an appropriate local law enforcement agency, which shall determine whether or not the petitioner is required to register as a sex offender pursuant to Section 290 of the Penal Code. (g) This section shall become operative on September 1, 2018.
