Ohio Rev. Code § 4509.61: Judgment creditor may bring action against bond.

If a judgment against a principal on a bond filed as proof of financial responsibility is not satisfied within thirty days after it has become final, the judgment creditor may, for his own benefit and at his sole expense, bring an action in the name of the state against the company or persons executing such bond, including an action to foreclose this lien upon the sureties' real estate.
