Most small businesses therefore do not issue checks with the length of time the check is valid printed on the face of the check. If your company writes a check, someone legally could attempt to cash it 10 months from now or in 18 months. Although banks can refuse to process checks that are over six months after the date on the check, rarely do the processors look at the date on the check.
When is a check considered stale dated and what if the bank pays the item after that time period? The Uniform Commercial Code, section 4-404, has effectively eliminated the old concept of stale dates on checks. However, the status of a check does change somewhat once it is 6 months old. If a check that is more than 6 months old is presented to the paying bank for payment, the paying bank may refuse to pay it without being liable to its customer (the drawer of the check) for so refusing. It may also pay the check if it does so in good faith.
