Ohio Rev. Code Ann. § 3905.64

Each controlling producer, prior to the effective date of an insurance policy, shall deliver a written notice to the prospective insured that fully and completely discloses the controlling relationship between the producer and the controlled insurer. If the business is placed through a subproducer that is not in control of the insurer, the subproducer shall provide to the producer a signed statement that the subproducer is aware of the controlling relationship between the insurer and the producer and that the subproducer has disclosed or will disclose that relationship to the insured. The producer shall retain the statement in his records.
