In addition to any other method provided by rule or by statute, personal jurisdiction over the parties may be acquired in a civil action or proceeding instituted in law or equity by service of process in the manner provided by law.

(b) A landlord who is not a resident of this state or is a corporation not authorized to do business in this state and engages in a transaction subject to this chapter may designate an agent upon whom service of process may be made in this state. The agent shall be a resident of this state or a corporation authorized to do business in this state. The designation shall be in writing, filed with the secretary of state, and must set forth the name and street address, including zip code, of the agent, the name and street address, including zip code, of the landlord and be accompanied by a ten-dollar filing fee. If no designation is made and filed or if process cannot be served in this state upon the designated agent, process may be served upon the secretary of state forthwith by mailing a copy of the process and pleading by registered or certified mail to the defendant or respondent at that party's last known address. The process must be accompanied by a ten-dollar fee and specify the address of the defendant. An affidavit of service shall be filed by the secretary of state with the clerk of the court on or before the return day of the process.
