Hello, you are guaranteeing a credit card for a friend. If he does not repay the credit card, you will be jointly and severally obligated to repay it during the guarantee period. There are risks in giving guarantee to others, so you need to be cautious.
According to the provisions of my country's "Guarantee Law", there are two forms of guarantee: general guarantee and joint liability guarantee.
If the parties agree in the guarantee contract that if the debtor cannot perform the debt, the guarantor shall bear the guarantee liability, it is a general guarantee; if the parties agree in the guarantee contract that the guarantor and the debtor shall bear joint and several liability for the debt, then Guarantee of joint and several liability.
