I think these three questions, 1, are valid, because both parties to this agreement are suitable, the contents of the contract do not violate the legal agreement, both parties are voluntary, and the agreement is valid. 2. If your friend doesn't repay the loan, your friend needs to bear the repayment obligation. Because this agreement is valid, but it is only an agreement between your friend and her friend. For the Women's Federation, the loan is based on your friend's certificate. When the money is not paid, you will ask your friends for it. After your friend repays the loan, you can recover it from her friend by agreement. 3. Loss is actually a legal risk. If your friend's friend runs away, or still can't catch up, your friend needs to bear this responsibility.
