Ohio Revised Code Title XIII. Commercial Transactions § 1317.02

Every retail installment sale shall be evidenced by an instrument in writing. A copy of said instrument shall be delivered to the retail buyer by the retail seller at the time of its execution. An acknowledgment of the delivery thereof contained in the body of the instrument is prima-facie proof of delivery in any action to enforce any obligation arising out of the retail installment sale. The written instrument shall contain all of the agreements of the parties, and shall set forth specifically all items and matters required by sections 1317.01 to 1317.11, inclusive, of the Revised Code. The reference to insurance shall recite generally the type of insurance the retail seller has agreed to procure for the retail buyer but such reference to insurance shall not be construed to imply the scope of the coverage, the terms, exceptions, limitations, restrictions, or condition of the contract of insurance to be furnished. Said sections do not require the retail seller to comply with this section at any time prior to the delivery of the specific goods to the retail buyer.
