Okla. Stat. tit. 43, § 43-601-614: Filing of modified child support order

Within thirty (30) days after issuance of a modified child

support order, the party obtaining the modification shall file a

certified copy of the order with the issuing tribunal that had

continuing, exclusive jurisdiction over the earlier order, and in

each tribunal in which the party knows the earlier order has been

registered. A party who obtains the order and 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 modified order of

the new tribunal having continuing, exclusive jurisdiction.
