1, the date of conclusion and the effective date of the contract are generally the same time, that is, the date when both parties sign and seal, which is the signing time.

2. Under special circumstances, if the two are inconsistent, the date of conclusion of the contract is the date of signature and seal, and the effective date is the specific time agreed by both parties or the time when the agreed conditions are completed.

Article 490 of the Civil Code of People's Republic of China (PRC) stipulates that if the parties conclude a contract in the form of a contract, the contract shall be established when both 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.
