but it depends on the bank and their policies how long a check is valid. We wrote a check once to a store that never cashed it. It’s a really long story but they didn’t cash it on purpose and then eventually lost the business to someone else. The new owner said it wasn’t in the store and he had no idea what the previous owners did with it. Our bank said the check was valid for cashing for two years maybe longer. It wasn’t a hard rule. If the check came in two years and two weeks they would allow it. If it was two years and 6 months, they wouldn’t. We had to keep that account open for that check to possible clear for two years. After that we closed the account.The person never did try to cash it cause they knew if they did, my husband and father in law would have been able to find out where he was and to sue him to access his account (they owed my FIL a lot of money). But we had to leave the account open just in case. If they had presented the check for cashing and there wasn’t money in the account, it would have bounced and we would have been hit with fees.
