@kevbo, you can endorse it “Pay to the Order of PandoraBoxx” and then sign your name. As PandoraBoxx, I will then sign it and deposit it to my account. My bank will then accept it for deposit, and then put a hold on the funds until the check clears. I would not be able to go to the original bank and cash the check.
The correct term for this transaction makes me the “holder in due course.”
