Ohio Rev. Code § 2101.03
Except as otherwise provided in section 3.061 of the Revised Code, before entering upon the discharge of official duties, the probate judge shall give a bond to the state in a sum not less than five thousand dollars. The bond shall have sufficient surety, shall be approved by the board of county commissioners or by the county auditor and county recorder in the absence from the county of two of the members of the board, and shall be conditioned that the judge will faithfully pay over all moneys received by the judge in the judge's official capacity, enter and record the orders, judgments, and proceedings of the court, and faithfully and impartially perform all the duties of the judge's office. The bond, with the oath of office required by sections 3.22 and 3.23 of the Revised Code indorsed on it, shall be deposited with the county treasurer and kept in the treasurer's office. As the state of business in the probate judge's office renders it necessary, the board, except as otherwise provided in section 3.061 of the Revised Code, may require the probate judge to give additional bond.
