Okla. Stat. tit. 43, § 43-601-207: Determination of controlling order

A. If a proceeding is brought pursuant to the Uniform

Interstate Family Support Act and only one tribunal has issued a

child support order, the order of that tribunal controls and must be

so recognized.

B. If a proceeding is brought pursuant to the Uniform

Interstate Family Support Act, and two or more child support orders

have been issued by tribunals of this state or another state or a

foreign country with regard to the same obligor and same child, a

tribunal of this state having personal jurisdiction over both the

obligor and individual obligee shall apply the following rules and

by order shall determine which order controls and must be

recognized:

1. If only one of the tribunals would have continuing,

exclusive jurisdiction pursuant to the Uniform Interstate Family

Support Act, the order of that tribunal control;

2. If more than one of the tribunals would have continuing,

exclusive jurisdiction under this act:

a. an order issued by a tribunal in the current home

state of the child controls, or

b. if an order has not been issued in the current home

state of the child, the order most recently issued

controls; and

3. If none of the tribunals would have continuing, exclusive

jurisdiction pursuant to the Uniform Interstate Family Support Act,

the tribunal of this state shall issue a child support order, which

controls.

C. If two or more child support orders have been issued for the

same obligor and same child, upon request of a party who is an

individual or that is a support enforcement agency, a tribunal of

this state having personal jurisdiction over both the obligor and

the obligee who is an individual shall determine which order

controls under subsection B of this section. The request may be

filed with a registration for enforcement or registration for

modification pursuant to Article 6 of this title, or may be filed as

a separate proceeding.

D. A request to determine which is the controlling order must

be accompanied by a copy of every child support order in effect and

the applicable record of payments. The requesting party shall give

notice of the request to each party whose rights may be affected by

the determination.

E. The tribunal that issued the controlling order under

subsection A, B, or C of this section has continuing jurisdiction to

the extent provided in Section 601-205 or 601-206 of this title.

F. A tribunal of this state that determines by order which is

the controlling order under paragraph 1 or 2 of subsection B or

subsection C of this section, or that issues a new controlling order

under paragraph 3 of subsection B of this section, shall state in

that order:

1. The basis upon which the tribunal made its determination;

2. The amount of prospective support, if any; and

3. The total amount of consolidated arrears and accrued

interest, if any, under all of the orders after all payments made

are credited as provided by Section 601-209 of this title.

G. Within thirty (30) days after issuance of an order

determining which is the controlling order, the party obtaining the

order shall file a certified copy of it in each tribunal that issued

or registered an earlier order of child support. A party or support

enforcement agency obtaining the order that fails to file a

certified copy is subject to appropriate sanctions by a tribunal in

which the issue of failure to file arises. The failure to file does

not affect the validity or enforceability of the controlling order.

H. An order that has been determined to be the controlling

order, or a judgment for consolidated arrears of support and

interest, if any, made pursuant to this section must be recognized

in proceedings under this act.
