1. Only signature, no identification.

Signing in the blank space of the main contract, if the guarantee agreement is not clear, cannot be automatically recognized as a guarantor, but it can be presumed as a witness.

2. If the IOU clearly states that it belongs to the guarantor, the guarantor shall bear the responsibility for the guarantee.

If the guarantor believes that the word "guarantor" on the IOU was added without authorization by the creditor afterwards. , then it bears the burden of proof for this claim and can apply for handwriting identification for confirmation. For example, if the IOU is written by the debtor, and the word "guarantor" is indeed added by the creditor afterwards, it can be determined that the "guarantor" did only sign in the blank space of the IOU. fact, the guarantee contract cannot be established and it will not bear guarantee liability.
