N.Y. Uniform Commercial Code Law § 4-405: Death or Incompetence of Customer

Section 4--405. Death or Incompetence of Customer.

(1) A payor or collecting bank's authority to accept, pay or collect

an item or to account for proceeds of its collection if otherwise

effective is not rendered ineffective by incompetence of a customer of

either bank existing at the time the item is issued or its collection is

undertaken if the bank does not know of an adjudication of incompetence.

Neither death nor incompetence of a customer revokes such authority to

accept, pay, collect or account until the bank knows of the fact of

death or of an adjudication of incompetence and has reasonable

opportunity to act on it.

(2) Even with knowledge a bank may for ten days after the date of

death pay or certify checks drawn on or prior to that date unless

ordered to stop payment by a person claiming an interest in the account.
