Ohio Revised Code Title XXI. Courts Probate Juvenile § 2109.61

An action may be prosecuted on the bond of a fiduciary against any one or more of the obligors on the bond by any person who has been injured by reason of the breach of any condition of the bond. The action shall be prosecuted for the benefit of all persons who are interested in the estate and who have been similarly injured. Any such person or any obligor on the bond who is not already a party to the action may intervene in the action or be made a party to the action by supplemental, amended, or cross-petition. Notice of any action or proceeding against the bonded fiduciary shall be given to the surety.

If a surety on the bond of a fiduciary is not made a party to an action or proceeding against the fiduciary, the fact that a judgment was rendered or an order was entered against the fiduciary shall constitute only prima-facie evidence of the justice and validity of the claim in an action subsequently brought against the sureties on the bond of the fiduciary.
