Ohio Code § 1304.59

§ 1304.59.

(A) If a receiving bank accepts a payment order issued in the name of its customer as

sender which is not authorized and not effective as the order of the customer under section 1304.57 of the Revised Code , or not enforceable, in whole or in part, against the customer under section 1304.58 of the Revised Code , the bank shall refund any payment of the payment order received from the customer

to the extent the bank is not entitled to enforce payment and shall pay interest on

the refundable amount calculated from the date the bank received payment to the date

of the refund.  The customer is not entitled to interest from the bank on the amount to be refunded

if the customer fails to exercise ordinary care to determine that the order was not

authorized by the customer and to notify the bank of the relevant facts within a reasonable

time not exceeding ninety days after the date the customer received notification from

the bank that the order was accepted or that the customer's account was debited with

respect to the order.  The bank is not entitled to any recovery from the customer on account of a failure

by the customer to give notification as stated in this section. (B) Reasonable time under division (A) of this section may be fixed by agreement as provided

in division (B) of section 1301.302 of the Revised Code , but the obligation of a receiving bank to refund payment as provided in division

(A) of this section may not otherwise be varied by agreement.
