Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC).

If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.

What is the role of signature and seal in the contract?

1, the function of signature and seal in contract signing is the other party's signature in contract documents. The parties who sign the contract documents are bound by the terms of the contract, even if they have not read these terms, unless there are factors such as fraud and incorrect statements;

2. Stamping and signing is mainly to confirm the conclusion of the contract, which proves that it is complete evidence in the future. A sealed or signed contract actually plays this role;

In today's reality, everyone can write and sign, and the debtor's signature has been widely required. Few people will accept unsigned documents and implement operations based on trust in them;

This is the signature or seal used when concluding a contract with a written contract, but it is not necessary to sign or seal an oral contract. This plays an important role in the establishment and effectiveness of the contract to a certain extent.
