Okla. Stat. tit. 43, § 43-601-313: Costs and fees

A. The petitioner may not be required to pay a filing fee or

other costs.

B. If an obligee prevails, a responding tribunal of this state

may assess against an obligor filing fees, reasonable attorney's

fees, other costs, and necessary travel and other reasonable

expenses incurred by the obligee and the obligee's witnesses. The

tribunal may not assess fees, costs, or expenses against the obligee

or the support enforcement agency of either the initiating or the

responding state or foreign country, except as provided by other

law. Attorney's fees may be taxed as costs, and may be ordered paid

directly to the attorney, who may enforce the order in the

attorney's own name. Payment of support owed to the obligee has

priority over fees, costs and expenses.

C. The tribunal shall order the payment of costs and reasonable

attorney's fees if it determines that a hearing was requested

primarily for delay. In a proceeding under Article 6 of this title,

a hearing is presumed to have been requested primarily for delay if

a registered support order is confirmed or enforced without change.
