Im a commercial lending compliance person attempting to help out the retail side this week during an exam and its been decades since I've handled consumer so please be kind

On a check that is returned NSF, is the bank required to send an image of that check to the customer? If we don't provide a copy of the check in their monthly bank statement, overdraft protection line statement or general NSF notice, are we okay? Is there at any point it is required?

a check your client wrote that was returned NSF? or a check that was written by another party that your client deposited and was returned as NSF by the paying bank?

a check our customer wrote

what does your contract with the client state you will provide?
