4-4-406.    Customer's duty to discover and report unauthorized signature or alteration -- Comparative fault.
    (a)  A  bank that sends or makes available to a customer a statement of account  showing payment of items for the account shall either return or make  available to the customer the items paid or provide information in the  statement of account sufficient to allow the customer reasonably to  identify the items paid. The statement of account provides sufficient  information if the item is described by item number, amount, and date of  payment.
(b)  If the items are not  returned to the customer, the person retaining the items shall either  retain the items or, if the items are destroyed, maintain the capacity  to furnish legible copies of the items until the expiration of seven (7)  years after receipt of the items. A customer may request an item from  the bank that paid the item, and that bank must provide in a reasonable  time either the item or, if the item has been destroyed or is not  otherwise obtainable, a legible copy of the item.
(c)  If  a bank sends or makes available a statement of account or items  pursuant to subsection (a), the customer must exercise reasonable  promptness in examining the statement or the items to determine whether  any payment was not authorized because of an alteration of an item or  because a purported signature by or on behalf of the customer was not  authorized. If, based on the statement or items provided, the customer  should reasonably have discovered the unauthorized payment, the customer  must promptly notify the bank of the relevant facts.
(d)  If  the bank proves that the customer failed, with respect to an item, to  comply with the duties imposed on the customer by subsection (c), the  customer is precluded from asserting against the bank:
      (1)  the  customer's unauthorized signature or any alteration on the item, if the  bank also proves that it suffered a loss by reason of the failure; and
      (2)  the  customer's unauthorized signature or alteration by the same wrongdoer  on any other item paid in good faith by the bank if the payment was made  before the bank received notice from the customer of the unauthorized  signature or alteration and after the customer had been afforded a  reasonable period of time, not exceeding thirty (30) days, in which to  examine the item or statement of account and notify the bank.
(e)  If  subsection (d) applies and the customer proves that the bank failed to  exercise ordinary care in paying the item and that the failure  substantially contributed to loss, the loss is allocated between the  customer precluded and the bank asserting the preclusion according to  the extent to which the failure of the customer to comply with  subsection (c) and the failure of the bank to exercise ordinary care  contributed to the loss. If the customer proves that the bank did not  pay the item in good faith, the preclusion under subsection (d) does not  apply.
(f)  Without regard to care  or lack of care of either the customer or the bank, a customer who does  not within one (1) year after the statement or items are made available  to the customer (subsection (a)) discover and report the customer's  unauthorized signature on or any alteration on the item is precluded  from asserting against the bank the unauthorized signature or  alteration. If there is a preclusion under this subsection, the payor  bank may not recover for breach of warranty under    4-4-208 with respect  to the unauthorized signature or alteration to which the preclusion  applies.
