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 [now § 1917] 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.
