Ohio Rev. Code § 309.11: Official bonds.

The prosecuting attorney shall prepare, in legal form, the official bonds for all county officers, and shall see that the acceptance of such bonds by the proper authorities, the signing thereof, and all the indorsements thereon, are in conformity to law, and that they are deposited with the proper officer. No bond shall be accepted or approved for any county officer by the person or tribunal authorized to approve it, until the prosecuting attorney has inspected it, and certified thereon that such bond is sufficient. In case of a vacancy in the office of prosecuting attorney or of the absence or disability of the prosecuting attorney, such duties shall be discharged by the probate judge.
