How Ping An Pratt & Whitney Loan becomes an unsigned guarantor may be an institutional problem.

The loan guarantor must sign. If the guarantor is a company, it should be stamped with the company seal or signed by the legal representative.

The loan guarantor establishes a guarantee contract relationship with the lender. The guarantor does not sign the guarantee contract or the guarantor in the loan contract, and the guarantor and the lender do not establish a guarantee contract relationship, so there is no guarantee responsibility.
