Legal subjectivity:

The signature on the IOU may not necessarily mean guarantee, it depends on the circumstances. If there is no guarantee clause in the debt certificate such as an IOU or loan contract, and the guarantor does not indicate that he assumes the guarantee responsibility when signing, the guarantor cannot be claimed to bear the responsibility, that is, there is no intention to guarantee. Unless there is only the signature or seal of another person and the identity of the guarantor is not indicated, it can be presumed that he is the guarantor in combination with other evidence. Legal objectivity:

Article 21 of the "Interpretation of the Supreme People's Court on Several Issues Concerning the Applicable Law in the Trial of Private Lending Cases" (hereinafter referred to as the "Private Lending Interpretation") stipulates that when another person's creditor's rights certificates such as IOUs, receipts, and IOUs are Or if the loan contract is signed or stamped but does not indicate the identity of the guarantor or assume the guarantee liability, or it cannot be inferred to be the guarantor through other facts, and the lender requests that it assume the guarantee liability, the people's court will not support it.
