(3) No default in any such action shall be taken, except upon affidavit certification of the board or the secretary of the board that a copy of the process or pleading was mailed to the defendant as provided in this subsection (b). No default judgment shall be taken in any such action or proceeding until thirty (30) days after the day of mailing of process or pleading to the defendant.
