Depends on specific circumstances. It is valid if the following requirements are met: (1) The parties to the contract have the corresponding capacity for civil rights and civil conduct; (2) The parties to the contract express true intentions; (3) The contract does not violate the law or social public interests. If the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal or fingerprint the contract. Legal objectivity:
Article 143 of the Civil Code is valid for civil legal acts that meet the following conditions: (1) The actor has the corresponding capacity for civil conduct; (2) The expression of intention is true; ( 3) Do not violate the mandatory provisions of laws and administrative regulations, and do not violate public order and good customs. Article 144 Civil legal acts performed by persons with capacity for civil conduct are invalid. Article 490: If the parties conclude a contract in the form of a contract, the contract shall be established when both parties sign, seal or fingerprint the contract. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it. Laws and administrative regulations stipulate or the parties agree that a contract should be concluded in written form. If the parties do not use written form but one party has performed its main obligations and the other party accepts it, the contract is established.
