Okla. Stat. tit. 36, § 36-1916: Claims of nonresidents against domestic insurers

A. In a delinquency proceeding begun in this state against a

domestic insurer, claimants residing in reciprocal states may file

claims either with the ancillary receivers, if any, in their

respective states, or with the domiciliary receiver. All such

claims must be filed on or before the last date fixed for the filing

of claims in the domiciliary delinquency proceedings.

B. Controverted claims belonging to claimants residing in

reciprocal states may either (1) be proved in this state, or (2) if

ancillary proceedings have been commenced in such reciprocal states,

may be proved in those proceedings. In the event a claimant elects

to prove his claim in ancillary proceedings, if notice of the claim

and opportunity to appear and be heard is afforded the domiciliary

receiver of this state as provided in section 1817 of this article

with respect to ancillary proceedings in this state, the final

allowance of such claim by the court in the ancillary state shall be

accepted in this state as conclusive as to its amount and shall also

be accepted as conclusive as to its priority, if any, against

special deposits or other security located within the ancillary

state.
