Ohio Revised Code Title XLVII. Occupations Professions § 4735.17

(A) The licensee, if a broker, shall maintain an active place of business in this state. A post office box is not an active place of business for purposes of this section.

(B) Every nonresident applicant shall file an irrevocable consent that suits and actions may be commenced against such applicant in the proper court of any county of this state in which a cause of action may arise or in which the plaintiff may reside by the service of any process or pleading authorized by the laws of this state on the superintendent of real estate. The consent shall stipulate that such service shall be taken and held in all courts as valid and binding as if proper service had been made upon the applicant in this state. The instrument containing such consent shall be authenticated by signature or by corporate seal. All applications of firms or corporations shall be accompanied by a certified copy of the resolution of the proper officers or managing board authorizing the proper officer to execute them. A duplicate copy of any process or pleading served on the superintendent shall be immediately forwarded by certified mail to the main office of the licensee against which that process or pleading is directed.
