Sorry, I signed my name vertically on a piece of white paper and gave it to others according to my fingerprint. If someone writes an IOU or something, is it legally binding?
Whether it has legal effect depends on the time and content of the loan. For example, if he writes a date, and you can prove that you were not there at all that day, it is impossible to meet this person and sign it, which is invalid. For example, the other party accidentally wrote the time of the debt two years ago, and the statutory limitation has passed, and the court will not support it. Find the flaw in the iou and refute it. After all, a fake is a fake.
