Okla. Stat. tit. 58, § 58-10: Transfer to county of domicile of minor or ward

In any case where it is shown to the court that the domicile of

a minor or ward has been changed from the county where the

guardianship is pending to another county in this state, the

guardianship may, upon application verified by oath, after notice

has been given to the next of kin of such minor or ward and upon

good cause shown, be removed to such other county, which would be

the proper venue, in the manner and upon the conditions prescribed

in the second preceding section for the transfer of suits, matters

or proceedings if the court finds that the domicile of the minor or

ward has been changed in good faith and that such transfer would be

for the best interest of such minor or ward.
