Once the borrower runs away and the debt cannot be paid off, as a guarantor, we should pay attention to whether it can be exempted from liability. Generally speaking, if the guarantee contract is invalid, the guarantor will be partially exempted.
legal ground
Article 687 of the Civil Code of People's Republic of China (PRC): The general guarantor enjoys the right of defense. Where the parties agree in the suretyship contract that the surety shall bear the suretyship liability when the debtor fails to perform the debt, it is a general suretyship. The guarantor of a general guarantee has the right to refuse to assume the guarantee liability to the creditor before the main contract dispute has been tried or arbitrated and the debtor's property has been enforced according to law, except in one of the following circumstances: (1) the debtor's whereabouts are unknown and there is no property available for execution; (2) The people's court has accepted the bankruptcy case of the debtor; (3) The creditor has evidence to prove that the debtor's property is insufficient to perform all debts or cannot perform debts; (4) The Guarantor waives the rights stipulated in this clause in writing.
