Do personal checks expire? [US]
It depends on the bank. According to the Uniform Commercial Code, a bank is not obliged to pay a cheque after six months, but may do so if it wants to. § 4-404.  BANK NOT OBLIGED TO PAY CHECK MORE THAN SIX MONTHS OLD. A bank is under no obligation to a customer having a checking account to pay a check, other than a certified check, which is presented more than six months after its date, but it may charge its customer's account for a payment made thereafter in good faith. Official link to UCC 4-404 As for your second question, if you stamp "void after 60 days" on your cheque; I don't have a specific answer for that part (yet). Update: I can find no specific rules about someone putting an arbitrary "void after xxx days" on their personal check. Businesess are alllowed to, but again the overriding rule seems to be that after six months it's the bank's choice, and you certainly couldn't make a cheque expire before six months, so I don't think that putting a stamp would make any difference. It's still up to the bank in the end.
