It is illegal for someone to forge an iou with his signature. If the circumstances are serious, it can constitute a crime, and the parties need to bear criminal responsibility according to law. Forged IOUs have no real loan relationship and are not protected by law. Creditors who hold IOUs claim rights from debtors, and they can argue that IOUs are forged. If the creditor is a person who forges debts, he can report the case directly to the public security organ.
