Generally, the guarantor and the joint debtor can be the same person, and the law of our country does not stipulate that the debtor cannot be the guarantor. A legal person, other organization or citizen who is capable of paying off debts on behalf of others may act as a guarantor.
[Legal basis] According to Article 683 of the Civil Code, an agency legal person may not be a guarantor, except for the use of loans from foreign governments or international economic organizations for re lending with the approval of the State Council.
A non-profit legal person or an unincorporated organization for the purpose of public welfare may not act as a guarantor.
