Ohio Rev. Code Ann. § 2113.65

The person investing unclaimed money under section 2113.64 of the Revised Code shall file in the probate court a memorandum thereof, with the original certificates or evidences of title representing such investment, which shall be allowed as a sufficient voucher for such payment under the order or decree. If the amount is unclaimed at the end of the period of such investment, it shall be turned into the county treasury and credited to the general fund, without liability for interest thereon. The receipt of the county treasurer taken for it and filed is a sufficient voucher.
