The effectiveness of the contract requires the parties to express their true will, and the contents of the contract do not violate the mandatory provisions of laws and regulations. No matter whether the contract is signed by only the parties, the contract established according to law is valid. According to Article 143 of the Civil Code, a civil juristic act that meets the following conditions is valid: (1) The actor has corresponding capacity for civil conduct; (2) the meaning is true; (three) does not violate the mandatory provisions of laws and administrative regulations, and does not violate public order and good customs. Paragraph 1 of Article 490 stipulates that a contract is concluded by the parties in the form of a contract, and the contract is established when the parties sign, seal or press their fingerprints.
