Section 34.55.036 - Service of process(a) In addition to the methods of service provided for in the Rules of Civil Procedure, service may be made by delivering a copy of the process to the department, but it is not effective unless (1) the plaintiff, which may be the department in a proceeding instituted by it, immediately sends a copy of the process and of the pleading by certified mail to the defendant or respondent at the last known address of the defendant or respondent; 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.(b) If a person, including a nonresident of this state, engages in conduct prohibited by this chapter or a regulation or order under this chapter, and has not filed a consent to service of process and personal jurisdiction cannot otherwise be obtained in this state, the department is authorized to receive service of process in any noncriminal proceeding against the person or the person's successor that grows out of that conduct and that is brought under this chapter or a regulation or order under this chapter, with the same force and validity as if served on the person personally. Notice shall be given as provided in (a) of this section.
