Effective, this contract will take effect after it is signed and sealed. If only the seal is unsigned, the contract will not take effect. 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

As long as a natural person has civil capacity, the contracts signed by both parties are generally valid. Contracts can be signed between natural persons, between natural persons and units, and between units, and contracts are generally valid. The signed contract is invalid if it violates laws, administrative regulations and social interests. The relevant laws do not clearly stipulate whether the contract will take effect only if it is sealed without signature. However, if the contract takes effect after it is signed and sealed, it must be signed and sealed in accordance with the contract. 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.

If the party that should go through the formalities for approval fails to perform its obligations, the other party may require it to bear the responsibility for violating its obligations.
