1. The signature on a bill generally refers to the signature of the drawer when the bill is issued, the signature of the endorser when the bill is transferred, the signature of the acceptor when the bill is accepted, the signature of the guarantor when the bill is guaranteed, the signature of the relevant agent when the bill is represented, and the signature of the holder when the bill is exercised.
2. Article 7 of the Negotiable Instruments Law stipulates that the signature on a negotiable instrument is signature, seal or signature plus seal. Legal persons and other units that use bills shall affix the seal of the legal person or unit on the bill, and affix the seal of its legal representative or its authorized agent. The signature on a bill of exchange shall be the real name of the party concerned.
3. Article 11 of the Measures for Payment and Settlement stipulates that the signatures on bills and settlement vouchers are signatures, seals or signatures and seals. The signature of the unit or bank on the bill and the signature of the unit on the settlement voucher are the signature of the unit or bank plus the signature of its legal representative or its authorized agent. The signature of an individual on bills and settlement vouchers shall be the signature or seal of his real name.
4. Rural credit cooperatives, city commercial banks, finance companies and other financial institutions may affix the official seal or special financial seal and the seal of the legal representative or authorized agent, without affixing the special draft seal.
5. The signature and seal of the drawer on the commercial bill shall be the "special financial seal" or official seal of the unit plus the signature or seal of its legal agent or its authorized agent.
note:
Because the bill signature is an important record in the bill behavior, if the signature on the bill does not conform to the relevant bill laws, the bill is invalid. If the signature of the acceptor or guarantor on the bill does not conform to the provisions of laws and regulations, its signature is invalid, but it does not affect the validity of other signatures that conform to the provisions of laws and regulations. If the endorser's signature on the bill does not conform to the provisions of laws and regulations, its signature is invalid, but it does not affect the validity of its predecessor's signature in conformity with the provisions of laws and regulations.
