He or she shall also file an order allowing or rejecting such claims as classified.

(2) When the director reclassifies or rejects a claim, which rejection shall be made when he or she doubts the legality of a claim, he or she shall serve written notice of such reclassification or rejection upon the claimant by either registered or certified mail and file, with the clerk of the district court of the county in which the main office of the bank is located, an affidavit of the service of such notice, which affidavit shall be prima facie evidence of such service. Such notice shall state the time and place for the filing by claimant of his or her objections to the classification, reclassification, or rejection of his or her claim.
