Legal analysis: the guarantor cannot revoke the guarantee. If the guarantee period stipulated in the loan contract expires, the guarantee relationship will be automatically dissolved after the expiration. If you want to cancel the guarantee, it depends on the relevant provisions of the guarantor, borrower and lending institution when signing the loan contract. Generally speaking, during the guarantee period stipulated in the contract, there is a joint relationship between the guarantor and the borrower.

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. ..
