the seal of the contract should be stamped on the signature, and it must be true and reliable. The signature must be signed by myself and face to face, so as to avoid being signed by others. According to the contract law, it is clearly stipulated that if the parties conclude a contract in the form of a contract, it will be established when both parties sign or seal it. Since the seal is a sign of the establishment of a contract, for the court of appeal, whether the parties seal the contract is an important evidence for the people's court to judge whether the contract has been effectively established. Generally speaking, once a contract is sealed by both parties, the parties will not have to provide additional evidence to prove that the contract has been established, and the resulting consequence is that the judge will not try whether the contract has been established. The judge will directly judge the performance of the parties' obligations based on this legal fact. Moreover, the judge will mainly judge the right and wrong and distinguish the responsibilities based on the sealed contract. On the contrary, if the contract is not sealed, the judge will investigate whether the contract is established. Stamping a contract requires the company to affix its official seal or special seal for the contract according to the specific contents of the contract. It is best to require the legal representative of the company to sign it. If someone else signs it on behalf of the company, you can judge whether you have the right to handle the affairs involved in the contract according to their authority. If you don't have the right, you can ask for an additional power of attorney. If the contract has multiple pages, it needs to be stamped with a riding seal, and all seals should be clear. And pay attention to whether the name of the unit seal corresponds to the name of the enterprise.
