Okla. Stat. tit. 36, § 36-4901: Sole surety on official bonds

Whenever any bond, recognizance, or undertaking is required or

permitted to be made for the security or protection of any person or

municipality, the state, or any department thereof, or organization,

conditioned for the doing or not doing of anything therein

specified, any such board, court, organization or officer required

or permitted to accept or approve of the sufficiency of such bond,

recognizance, or undertaking, may accept and approve the same when

executed, or when the conditions thereof are guaranteed, solely by

an insurer authorized to transact a surety business in this state in

accordance with the requirements of this code. Whenever any such

bond, recognizance, or undertaking is required to be made with one

surety or with two or more sureties, the execution of the same, or

the guarantee of the performance of the conditions thereof, shall be

sufficient when so executed or guaranteed solely by one such

insurer, and shall be a full compliance with every requirement of

every law, ordinance, or regulation relating to the same, and no

justification by such insurer shall be necessary.
