1, the personal seal has legal effect once it is filed by the public security organ or approved by the signatory.

2. If the parties conclude a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints.

3. Unless otherwise provided by law.

Whether the personal seal has legal effect depends on the situation, as follows:

1. Personal seal shall have legal effect if it is filed by the public security organ.

2. If the seal has not been filed by the public security organ, but the signer recognizes its signature, it also has legal effect. If the parties conclude a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Except as otherwise provided by law.

3. If the seal has not been put on record by the public security organ or approved by myself, it has no legal effect.

To sum up, if the parties conclude a contract in the form of a contract, the contract shall be established when both parties sign or seal it. There is no clear boundary between the seal and the official seal of a contract. In fact, the company's special seal for contracts and the company's official seal have legal effect when signing contracts on behalf of the company. The evaluation of the legal effect of the seal by expansive materials is a kind of value judgment rather than fact determination, so it is mainly reflected in the event of disputes.

Legal basis:

People's Republic of China (PRC) Civil Code

Article 490

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.
