Okla. Stat. tit. 30, § 30-3-314: Rules for filing of petitions in multiple states

Except for a petition for the appointment of a guardian in an

emergency or issuance of a protective order limited to property

located in this state under paragraph (1) or (2) of subsection (a)

of Section 9 of this act, if a petition for the appointment of a

guardian or issuance of a protective order is filed in this state

and in another state and neither petition has been dismissed or

withdrawn, the following rules apply:

(1) If the court in this state has jurisdiction under Section 8

of this act, it may proceed with the case unless a court in another

state acquires jurisdiction under provisions similar to Section 8 of

this act before the appointment or issuance of the order.

(2) If the court in this state does not have jurisdiction under

Section 8 of this act, whether at the time the petition is filed or

at any time before the appointment or issuance of the order, the

court shall stay the proceeding and communicate with the court in

the other state. If the court in the other state has jurisdiction,

the court in this state shall dismiss the petition unless the court

in the other state determines that the court in this state is a more

appropriate forum.
