Personal Checks. The financial institution redeeming a check determines the expiration date of a personal check. The Uniform Commercial Code permits the accepting institution to decide whether it will redeem checks dated more than six months before the date you take the check to the institution.
Checks are valid 6 months, cashier checks for 1 year. Sometimes banks cash them anyway after they expire though. US Post Office MOs are valid forever. For banks, and other countries, call the bank or PO and ask.
