California Code, Financial Code - FIN § 31113

Before any applicant for a license is issued a license, such applicant and each parent and subsidiary of such applicant shall file, and each person who becomes a parent or subsidiary of a licensee shall, not less than 30 days after becoming a parent or subsidiary of such licensee, file, with the commissioner, in such form as the commissioner may by regulation or order require, an irrevocable consent appointing the commissioner and his or her successor from time to time in office to be such person's attorney to receive service of any lawful process in any noncriminal judicial or administrative proceeding against such person, or his or her successor, executor, or administrator, which arises under this division or under any regulation or order issued under this division after such consent has been filed, with the same force and validity as if served personally on such person. Service may be made by leaving a copy of the process at any office of the commissioner, but such service is not effective unless (a) the party making such service, who may be the commissioner, forthwith sends notice of such service and a copy of the process by registered or certified mail to the party served at his or her last address on file with the commissioner, and (b) an affidavit of compliance with this section by the party making service is filed in the case on or before the return date, if any, or within such further time as the court, in the case of a judicial proceeding, or the administrative agency, in the case of an administrative proceeding, allows.
