TN Code § 47-4-406 (2021)
2021 Tennessee Code|Title 47 - Commercial Instruments and Transactions|Chapter 4 - Bank Deposits and Collections|Part 4 - Relationship Between Payor Bank and Its Customer|§ 47-4-406. Customer's Duty to Review Statements of Account

  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.   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.   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 (i) any payment was not authorized because of an alteration of an item or an unauthorized signature purportedly made by or on behalf of the customer, or because the payment was made in an incorrect amount, or (ii) a deposit is missing or has been incorrectly credited. If, based on the statement or items provided, the customer should reasonably have discovered the unauthorized payment or missing or incorrectly credited deposit, the customer must promptly notify the bank of the relevant facts.   If the bank proves that the customer failed, with respect to an item or deposit, to comply with the duties imposed on the customer by subsection (c), the customer is precluded from asserting against the bank:  Such payment or missing or incorrectly credited deposit, if the bank also proves that it suffered a loss by reason of the failure; and   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.     If the customer proves that the bank did not pay the item in good faith, the preclusion under subsection (d) does not apply.   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 an occurrence referred in subsection (c) is precluded from asserting against the bank any claim with respect thereto. If there is a preclusion under this subsection, the payor bank may not recover for breach of warranty under § 47-4-208 with respect to the unauthorized signature or alteration to which the preclusion applies.
