Legal analysis: legal person signature is the signature of legal person organization on bill. As we all know, it is impossible for a legal person to make any signature. In practice, when a legal person needs to sign a bill, the essence is made by a natural person, which is also a general rule. For the way of legal person signature, most theories think that it is limited to the form of seal. Some scholars also believe that the representative can directly sign the name of the legal person in calligraphy, or it can be regarded as the signature of the legal person. The argument is that a natural person can sign by hand, and a legal person should also have the handwritten signature of a natural person. There is no obstacle. But most countries in the world require legal person registration, because legal persons exist in the abstract. Only when a legal person is registered can it be regarded as open, credible and well-known, which is an extremely important guarantee for transaction security. If the natural calligrapher's name is used as the legal person's signature, it may cause a lot of inconvenience because of the fixity of the signer and the instability of the handwriting. If the handwritten legal person names of multiple natural persons are used as legal person signatures, besides the diversity of handwriting, the possibility of signature abuse is obviously increased, which will bring serious consequences. From this perspective, the representative of a legal person can only be a seal, not a legal person name in calligraphy.
