Legal analysis: the guarantor cannot easily revoke the guarantee, after all, the contract has been signed. If the borrower has paid off, then you can apply to the bank to issue a certificate to relieve the guarantee responsibility. In addition, it should be noted that if a general guarantee is signed, as long as the borrower has repayment ability, the main responsibility lies with the borrower, which has little influence on the guarantor and does not need to be cancelled; If joint and several liability is signed, the creditor's consent is required before going to the bank to apply for cancellation.
