Signature and seal return means signature and seal. A contract is generally valid without seal, but it is invalid if there is an agreement signed and sealed. Generally speaking, a contract is valid as long as it is the true intention of both parties. Without the seal, the validity of the contract itself cannot be denied. Unless otherwise specified, for example, a contract without seal is invalid, or a contract without company seal is invalid. In trading activities, signature and seal are the basic requirements of many laws.

Legal analysis

This contract shall come into effect after being signed and sealed. If only the seal is unsigned, the contract will not come into effect. The seal is the unit and the signature is the individual, including the legal person of the unit. The seal of the unit is valid even if the legal person does not sign it. If it is only stamped, the contract will not take effect. Of course, if one party fulfills its main obligations and the other party accepts them, the contract will be regarded as established and effective in law. If a contract is concluded in the form of a contract, one party has fulfilled its main obligations before signing or sealing it, and the other party accepts it, the contract is established. First of all, this is determined by the nature of the contract. A contract is the product of the parties' consensus, and it is an agreement between two or more subjects expressing the same meaning. Under normal circumstances, only signature or seal can show the parties' approval of the terms of the contract. However, if one party performs its obligations according to the contract and the other party accepts the obligations before the contract is signed or sealed, the contract will take effect. The entry into force of a contract requires certain conditions, and the entry into force of a contract can be divided into several categories: first, a contract established according to law takes effect as soon as it is established. Second, except as agreed by the parties, if the examination and approval and registration procedures need to take effect according to the provisions of laws and administrative regulations, they will take effect when the legal procedures are fulfilled. Third, although the contract is established, it can only take effect when it meets the effective conditions agreed by both parties or when the effective period agreed by both parties expires.
