how long do checks expire after already being written
If you wrote the check, the only way to guarantee that you will not be liable for it longer than six months is to place a stop payment order on it. According to Bankrate.com, an oral stop-payment order expires after 14 days and a written stop-payment order expires in six months. You must renew stop-payment orders every six months to ensure that you are not held liable for old checks; banks typically charge a fee for each order.
