2005 California Corporations Code Sections 31420 CHAPTER 4. SERVICE OF PROCESS

31420.  When any person, including any nonresident of this state,
engages in conduct prohibited or made actionable by this law or any
rule or order hereunder, whether or not he has filed a consent to
service of process under Section 31155, and personal jurisdiction
over him cannot otherwise be obtained in this state, that conduct
shall be considered equivalent to his appointment of the commissioner
or his successor in office to be his attorney to receive service of
any lawful process in any noncriminal suit, action, or proceeding
against him or his successor, executor, or administrator which grows
out of that conduct and which is brought under this law or any rule
or order hereunder, with the same force and validity as if served on
him personally.  Service may be made by leaving a copy of the process
in the office of the commissioner, but it is not effective unless
(a) the plaintiff, who may be the commissioner in a suit, action, or
proceeding instituted by him, forthwith sends notice of the service
and a copy of the process by registered or certified mail to the
defendant or respondent at his last known address or takes other
steps which are reasonably calculated to give actual notice, and (b)
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.
