(a) If upon the granting of an order of liquidation under this article or at any time thereafter during the liquidation proceeding, the insurer shall not be clearly solvent, the court shall, after notice and hearing as provided in this article, make an order declaring the insurer to be insolvent. Thereupon regardless of any prior notice which may have been given to creditors, the commissioner shall notify all persons who may have claims against the insurer and who have not filed proper proofs thereof to present the same to him or her, at a place specified in the notice, within four months from the date of entry of the order, or if the commissioner shall certify that it is necessary, within such longer time as the court shall prescribe. The last day for filing of proofs of claims shall be specified in the notice and notice shall be given in a manner to be determined by the court.
(b) Proofs of claim may be filed subsequent to the date specified, but no such claim may share in the distribution of the assets until all allowed claims, proofs of which have been filed before said date, have been paid in full with interest, except as provided in section twenty-six-d of this article.
