In our Terms and Conditions agreement given to the customer at account opening, there is a statement addressing that due to electronic check conversions, we may have no opportunity to review a check to examine the signature on the item. You agree that, as to these or any items as to which we have no opportunity to examine the signatures, you waive any requirement of multiple signatures.... would this suffice or would we need some type of additional hold harmless agreement? if so, what would it need to state?
