The answer is definitelyno. If the other party does this without your knowledge, it is fraud. But you should be careful. If this person lends money to individuals or banks, it is in good faith without their knowledge, and a third party is legally needed to protect their rights and interests. That is, if someone else doesn't pay it back, you have to pay it back for him, and then you are looking for that person to ask for it. Without your understanding and malice, who is this? If you want him to help you with the loan, you can get it without your signature.
