Best Answer: Most banks will not accept any cheques more than six months old-even though they are legally valid for six years. However, that six years relates to payment of a debt-and may not apply in the case of a gift.This is a formal statement of the legal position: A cheque is valid for as long as the debt between the two parties (i.e. issuer and payee) exists. In other words, cheques do not have an expiration date.owever, that six years relates to payment of a debt-and may not apply in the case of a gift.
