Legal analysis: the guarantor helps the lender pay back the money when he can't pay it back. Because the lender lacks financial resources, the bank requires a guarantor. At this time, the guarantor should clearly know the joint liability. After being sued by the court, the court will judge the lender to fulfill the repayment obligation. After applying for compulsory execution of the lender, it is found that the lender is unable to repay, and the loan guarantor will be judged to repay the loan and the interest owed. At present, there is no good solution, and the guarantor can only assume the responsibility as a guarantor. Otherwise, the court will seal up the property under the guarantor's name, including real estate, to repay the loan.

Legal basis: Article 388 of the Civil Code of People's Republic of China (PRC) establishes a security interest, and a security contract shall be concluded in accordance with this law and other laws. Guarantee contracts include mortgage contracts, pledge contracts and other contracts with guarantee functions. The guarantee contract is a subsidiary contract of the main creditor's rights and debts contract. If the principal creditor's rights and debts contract is invalid, the guarantee contract is invalid, unless otherwise stipulated by law. If the debtor, guarantor and creditor are at fault after the guaranty contract is confirmed to be invalid, they shall bear corresponding civil liabilities according to their faults.
