Ohio Revised Code Title LIII. Real Property § 5309.44

No new certificate of title shall be entered, and no memorandum shall be made upon the register of any certificate of title by the county recorder in pursuance of any deed or other voluntary instrument, unless the owner's duplicate certificate is presented with such instrument, except in cases expressly provided for in sections 5309.02 to 5310.21, inclusive, of the Revised Code, or upon the order of the probate court or the court of common pleas, for cause shown. Whenever such order is made, a memorandum thereof shall be entered on the new certificate of title and on the owner's duplicate. The production of the owner's duplicate, whenever a voluntary instrument is presented for registration, is authority from the registered owner to the recorder to enter a new certificate or to make a memorial of registration in accordance with such instrument, and the new certificate or memorial shall be binding upon the registered owner and upon all persons claiming under him, in favor of every purchaser and holder for value and in good faith and in favor of all persons holding under such purchaser and holder. In all cases of registration which are procured by fraud, the owner may pursue all his legal and equitable remedies against the parties to such fraud, without prejudice to the rights of any innocent holder for value of a certificate of title or any person holding under such innocent holder.

After the entering and issuing of a certificate of title by the recorder on the decree of registration under the original application, any subsequent registration which is procured by the presentation of a forged duplicate certificate, or of a forged deed or other instrument, shall be void. In case of the loss or theft of an owner's duplicate certificate, notice shall be sent by the owner, or by a person in his behalf, to the recorder of the county in which the land lies, as soon as the loss or theft is discovered.
