New York Consolidated Laws, Debtor and Creditor Law - DCD § 5. Notice to creditors to present claims

The judge may, upon the petition of the assignee, authorize him to advertise for creditors to present to him their claims, with the vouchers therefor, duly verified, on or before a day to be specified in such advertisement, not less than ten days from the publication thereof, which advertisement or notice shall be published in one newspaper, to be designated by the judge, as most likely to give notice to the persons to be served, at least once and such additional times as the judge may direct;  the last publication shall be at least one week prior to the date specified.

Said verified claim of creditor shall set forth whether any, and, if so, what securities are held for such claim, and whether any, and, if so, what payments have been made thereon.

Whenever a claim is founded upon an instrument in writing, such instrument, unless lost or destroyed, shall be filed with the claim.  After the claim is allowed or disallowed, such instrument may be withdrawn by permission of the court.  If such instrument is lost or destroyed, a statement of such fact and of the circumstances of such loss or destruction shall be filed under oath with the claim.
