I was recently witness to a salesman claiming that a customer could post-date a check to guarantee their check would not be cashed before the item they just ordered was received.
I was under the impression that this is false, and that writing post-dated checks can actually be considered illegal under some of the worthless-check laws here in the United States.
But it was suggested that, perhaps, having such a check would make it illegal for the business to cash the check… but I believe that would make the check writer liable, and not the business that cashed it.
So does a post-dated check have any valid use in a business or personal transaction? Does it provide any financial or legal protections under US law or banking regulations?
