N.D. Cent. Code § 26.1-06.1-39
Whenever a creditor whose claim against an insurer is secured, in whole or in part, by the undertaking of another person, fails to prove and file that claim, the other person may do so in the creditor's name, and must be subrogated to the rights of the creditor, whether the claim has been filed by the creditor or by the other person in the creditor's name, to the extent that the other person discharges the undertaking. In the absence of an agreement with the creditor to the contrary, the other person is not entitled to any distribution; however, until the amount paid to the creditor on the undertaking plus the distributions paid on the claim from the insurer's estate to the creditor equals the amount of the entire claim of the creditor. Any excess received by the creditor must be held by the creditor in trust for such other person. The term "other person" as used in this section is not intended to apply to a guaranty association or foreign guaranty association.
