Cal. Corporations Code § 25165

Every applicant for qualification of the sale of securities under this law or every person filing an application or a notice under Sections 25100.1, 25101.1, 25102.1, and 25230.1 or a request for or notice of an exemption from qualification (other than a California corporation, California limited partnership, California limited liability company, or a person licensed as a broker-dealer in this state) shall file with the commissioner, in such form as prescribed by rule, an irrevocable consent appointing the commissioner or his or her successor in office to be the applicant’s or person’s attorney to receive service of any lawful process in any noncriminal suit, action or proceeding against the applicant or person or the successor, executor or administrator thereof, which arises under this law or any rule or order hereunder after the consent has been filed, with the same force and validity as if served personally on the person filing the consent. A person who has filed such a consent in connection with a previous qualification under this law (or application for a permit under any prior law if the application under this law states that such consent is still effective), or in connection with a notice filing under Section 25100.1, 25101.1, 25102.1, and 25230.1, need not file another. Service may be made by leaving a copy of the process in the office of the commissioner but it is not effective unless (1) the plaintiff, who may be the commissioner in a suit, action or proceeding instituted by him or her, forthwith sends notice of the service and a copy of the process by registered or certified mail to the defendant or respondent at the last address on file with the commissioner, and (2) the plaintiff’s affidavit of compliance with this section is filed in the case on or before the return day of the process, if any, or within such further time as the court allows.
