Ohio Revised Code Title XXXIX. Insurance § 3929.14

When a bond, recognizance, or undertaking is required or permitted by law, with one or more sureties, its execution or the guaranteeing thereof, as sole surety, is sufficient if done by a company authorized to guarantee the fidelity of persons holding places of public or private trust, to guarantee the performance of contracts other than insurance policies, and to execute and guarantee bonds and undertakings in actions or proceedings or allowed by law. When a bond, recognizance, or undertaking is so executed and guaranteed by such a company, it is a full compliance with every requirement of law, ordinance, rule, or regulation that such bond or recognizance must be executed and guaranteed by one surety or two or more sureties, or that such sureties shall be residents, householders, or freeholders.
