New York Laws
Part 2 - Warehouse Receipts: Special Provisions
7-208 - Altered Warehouse Receipts.


If a blank in a negotiable tangible warehouse receipt has been filled
in without authority, a good-faith purchaser for value and without
notice of the lack of authority may treat the insertion as authorized.
Any other unauthorized alteration leaves any tangible or electronic
warehouse receipt enforceable against the issuer according to its
original tenor.
