Ohio Rev. Code Ann. § 2937.42

Forfeiture of a recognizance shall not be barred or defeated or a judgment thereon reversed by the neglect or omission to note or record the default, or by a defect in the form of such recognizance, if it appears from the tenor thereof at what court the party or witness was bound to appear and that the court or officer before whom it was taken was authorized to require and take such recognizance.
