Legal analysis
A valid contract must meet the following requirements. First, the subject of the contract must have the capacity for civil conduct stipulated by relevant laws, and second, the will is true. Third, the content of the contract does not violate the law or the public interest. Therefore, as long as the above conditions are met, the agreement signed by both parties has legal effect, but if it belongs to a special type of contract, such as a practice contract and a loan contract. The contract can only be established after both parties sign it, but it will only take effect after the lender delivers the lent money to the borrower. Therefore, it cannot be said with complete certainty that the contract signed by both parties will definitely take effect. Generally speaking, a legally established contract takes effect as soon as it is established. However, some laws or administrative regulations stipulate that certain types of contracts must be approved and registered before they can take effect. In this case, the contract will not take effect immediately after the parties conclude it. The parties concerned must go through the approval or registration procedures with the relevant departments in accordance with the provisions of laws and administrative regulations. After the contract is approved or registered, it has legal effect, and the rights and obligations of the parties are recognized by law.

Article 490 of the Civil Code of People's Republic of China (PRC): If the parties conclude a contract in the form of a contract, the contract is concluded when the parties sign, seal or fingerprint it. 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.
