It depends on the form of its guarantee.
First, the general guarantee responsibility
Its responsibility is that when the debtor can't pay off the due debt, the guarantor should bear the responsibility, that is, pay off the due debt.
Second, joint and several liability
The creditor's responsibility to pay means that when the debt reaches the repayment period, the creditor has the right to ask the debtor or guarantor to repay the debt.
When the guarantee is a general guarantee, the guarantor has the right of defense, that is, the guarantor has the right to refuse the creditor's repayment request before the creditor applies to enforce the debtor's property or fails to enforce the security interest. Co-guarantors have no such right.
Third, cancel the responsibility of the guarantor
If the same creditor's right is secured by two things, after the expiration of the main contract, if the creditor is slow to exercise the right to guarantee, resulting in the decrease of the value of the collateral or damage or loss, it shall be deemed that the creditor has waived the guarantee of part or all of the property, and the guarantor shall reduce or exempt the guarantee liability within the scope of the creditor's waiver of rights.
The above is a summary of what the guarantor should bear as a guarantee and what the legal responsibility is, hoping to bring some help to everyone.
