N.Y. Debtor & Creditor Law § 62: When non-resident creditor to annex accounts and securities

§ 62. When non-resident creditor to annex accounts and securities. A

consenting creditor, residing without the state, and within the United

States, must annex to his consent the original accounts, or sworn copies

thereof, and the original specialties or other written securities, if

any, upon which his demand arose or depends. Provided, however, that

when such original specialties, or other written securities, are lost,

such fact must be stated as a reason for not annexing thereto the

consent, and the fact of the loss, and the manner of the loss thereof

must be stated in the affidavit of the creditor to the best of his

knowledge, or must be otherwise proved by affidavit to the satisfaction

of the court; and the court may thereupon, in such case or proceeding,

by its order, dispense with the annexing to such consent of the original

specialties or other written securities.
