Okla. Stat. tit. 43, § 43-601-507: Administrative enforcement of orders

A. A party or support enforcement agency seeking to enforce a

support order or an income-withholding order, or both, issued in

another state or a foreign support order may send the documents

required for registering the order to a support enforcement agency

of this state.

B. Upon receipt of the documents, the support enforcement

agency, without initially seeking to register the order, shall

consider and, if appropriate, use any administrative procedure

authorized by the law of this state to enforce a support order or an

income-withholding order, or both. If the obligor does not contest

administrative enforcement, the order need not be registered. If

the obligor contests the validity or administrative enforcement of

the order, the support enforcement agency shall register the order

pursuant to this act.
