Do Not endorse the check and attempt to deposit it in your account. Take the check and your customer reciept copy that was given to you when the check was purchased, to the bank.
Tell them it is not going to be used and you want to cancell it.
The bank will take both the check and your customer copy stamp the check "Not used for purpose intended" and tear off the authorized signature on the original check.
There is an internal bookeeping process that will take place, which means they will pull their copy attach, the Original Check and your copy to their copy, and off set their General Ledge Account with a credit to our account.
THIS IS NOT A VIOLATION OF UCC. A bank may cancell a Cashiers Check, Money Order, or what ever item they issue in this manner.
A bank issued item can be cancelled but not stopped and there seems to be some confusion on this.
