Okla. Stat. tit. 43, § 43-551-305: Registration of child custody determination

REGISTRATION OF CHILD CUSTODY DETERMINATION

A. A child custody determination issued by a court of another

state may be registered in this state, with or without a

simultaneous request for enforcement, by sending to the appropriate

court in this state:

1. A letter or other document requesting registration;

2. Two copies, including one certified copy, of the

determination sought to be registered, and a statement under penalty

of perjury that to the best of the knowledge and belief of the

person seeking registration the order has not been modified; and

3. Except as otherwise provided in Section 21 of this act, the

name and address of the person seeking registration and any parent

or person acting as a parent who has been awarded custody or

visitation in the child custody determination sought to be

registered.

B. On receipt of the documents required by subsection A of this

section, the registering court shall:

1. Cause the determination to be filed as a foreign judgment,

together with one copy of any accompanying documents and

information, regardless of their form; and

2. Serve notice upon the persons named pursuant to paragraph 3

subsection A of this section and provide them with an opportunity to

contest the registration in accordance with this section.

C. The notice required by paragraph 2 of subsection B of this

section must state that:

1. A registered determination is enforceable as of the date of

the registration in the same manner as a determination issued by a

court of this state;

2. A hearing to contest the validity of the registered

determination must be requested within twenty (20) days after

service of notice; and

3. Failure to contest the registration will result in

confirmation of the child custody determination and preclude further

contest of that determination with respect to any matter that could

have been asserted.

D. A person seeking to contest the validity of a registered

order must request a hearing within twenty (20) days after service

of the notice. At that hearing, the court shall confirm the

registered order unless the person contesting registration

establishes that:

1. The issuing court did not have jurisdiction under Article 2

of this act;

2. The child custody determination sought to be registered has

been vacated, stayed, or modified by a court having jurisdiction to

do so under Article 2 of this act; or

3. The person contesting registration was entitled to notice,

but notice was not given in accordance with the standards of Section

8 of this act, in the proceedings before the court that issued the

order for which registration is sought.

E. If a timely request for a hearing to contest the validity of

the registration is not made, the registration is confirmed as a

matter of law and the person requesting registration and all persons

served must be notified of the confirmation.

F. Confirmation of a registered order, whether by operation of

law or after notice and hearing, precludes further contest of the

order with respect to any matter that could have been asserted at

the time of registration.
