Section 620 - Notice to creditors to make proof of claims; form of claims; claims for priority of payment1. When the superintendent shall have taken possession of any banking organization, and shall have determined to liquidate its affairs, he or she shall notify all persons who may have claims against such banking organization to present such claims to him or her and make proper proof thereof within four months from the date of such notice and at a place specified therein; provided, that (a) if the superintendent finds that a shorter period than four months will afford a reasonable time for presenting claims and making proof thereof, he or she may specify such shorter period which shall in no event be less than thirty days or (b) if the superintendent finds that a longer period than four months is needed to afford a reasonable time for presenting claims and making proof thereof, he or she may specify such longer period which shall in no event be more than six months from the date of such notice. In any event the superintendent shall specify in such notice the last date for presenting claims and for making proof thereof. The superintendent shall cause such notice to be mailed to all persons whose names appear as creditors upon the books of the banking organization. Such notice to persons appearing as depositors shall be mailed to the address appearing upon the deposit records or ledger of such banking organization. The superintendent shall also cause such notice to be inserted biweekly in such newspaper or newspapers as he or she may direct for three consecutive months, the first insertion thereof to be published more than ninety days before the last day fixed in such notice for presenting proof of claims; provided, that where the notice requires claims to be presented within less than four months, the superintendent shall cause such notice to be inserted weekly in such newspaper or newspapers as he or she may direct for three consecutive weeks, the first insertion thereof to be published more than twenty-one days before the last day fixed in such notice for presenting claims. Such notice shall specify that all persons having claims for priority of payment shall make demand in writing for priority in the proof of their claims. The superintendent shall have no power to accept any claim presented after the date specified in such notice as the last date for presenting claims.2. A proof of claim shall consist of a written statement under oath signed by the claimant or his attorney in fact, and shall be in such form as the superintendent shall require.3. All persons who shall have failed to demand in writing priority of payment as specified in the notice to file claims shall be deemed to have waived and abandoned any right to such priority of payment. No person who shall have failed to demand in writing priority of payment as herein above provided, shall be entitled to maintain any action or proceeding for any priority of payment. In all actions or proceedings for priority of payment, the claimant shall be required to allege and prove that the claim upon which the action is instituted was duly filed and contained therein demand in writing for priority of payment.
