Legal analysis
Whether the contract signed by Party A and Party B is valid or not depends on the following points: 1. The content of the contract is legal, and the signing of the contract is the true intention of both parties. Then the contract is valid if Party B signs it, but Party A does not sign it, but both parties seal it or both parties have fulfilled their main obligations. 2. If the above conditions are not met, the contract is invalid. If this contract is a written contract with only the signature of Party B, but not the signature and seal of Party A, this contract is invalid. If the contract is electronic, a confirmation letter must be signed in advance, otherwise the contract will be invalid. Since it is a contract, it needs to be signed by both parties. 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.
