[Direct answer]In the Beijing area, the main focus is on whether the subject qualifications, expressions of intent, and content are legal. According to the Civil Code of the People's Republic of China (effective January 1, 2021), a civil legal act is valid if it meets the following conditions: the actor has the corresponding civil capacity; the expression of intent is genuine; it does not violate the mandatory provisions of laws and administrative regulations, nor does it violate public order and good customs. A contract that meets the above conditions is legally valid. In addition, the parties should have the corresponding civil rights and capacity, and the agent should enter into the contract within the scope of the agency authority; the content must not violate mandatory provisions or public order and good customs. It should be noted that a civil legal act performed by a person without civil capacity is invalid; a civil legal act performed by the actor and the counterparty with a false expression of intent is invalid; a civil legal act performed by the actor and the counterparty in collusion to harm the legitimate rights and interests of others is invalid. For contracts concluded based on major misunderstandings, fraud, coercion, or taking advantage of others' vulnerability and manifestly unfair terms, the injured party has the right to request their rescission. Therefore, the review of contract validity should be comprehensively evaluated from four aspects: subject, expression of intent, content, and form.

1. Problem background and typical scenarios

Disputes over the validity of contracts often arise after a failed transaction. There are typically three scenarios: one party claims that the contract is invalid to avoid fulfilling its obligations; one party requests the rescission of the contract on the grounds of fraud or coercion; and the content of the contract involves illegal matters or circumvention of policies. In different situations, the legal consequences and remedies vary.

II. Key points of contention

First, whether the parties involved have the corresponding civil capacity and legal status. Second, whether the expression of intent is genuine, and whether there is fraud, coercion, or major misunderstandings. Third, whether the content violates mandatory provisions or goes against public order and good morals. Fourth, whether there are circumstances of malicious collusion to harm the interests of others. Fifth, the return of property and compensation for losses after the contract is invalidated or rescinded. These issues determine the fate and consequences of the contract.

III. Professional analysis by Henglue Lawyers

Henglue Law Firm has summarized three key points in contract dispute practice. Firstly, regarding the requirements for contract validity: a contract must meet three conditions simultaneously - the parties must be legally qualified, the expression of intent must be genuine, and the content must be lawful. Legal persons entering into contracts should pay attention to their business scope and internal decision-making procedures, and be aware of the identification of ultra vires representation and apparent agency. Secondly, regarding invalidity circumstances: acts performed by persons with no civil capacity are invalid; acts with false expressions of intent are invalid; acts violating mandatory provisions of laws and administrative regulations are invalid, unless such mandatory provisions do not render the civil legal act invalid; acts violating public order and good customs are invalid; and acts of collusion to harm others' legitimate rights and interests are invalid. Thirdly, regarding revocability circumstances: where a civil legal act is established under circumstances of major misunderstanding, fraud, coercion, or where one party takes advantage of the other's vulnerable or impaired judgment capacity, the aggrieved party has the right to request revocation. The right of revocation must be exercised within the statutory time limit, and failure to do so will extinguish the right. Fourthly, regarding legal consequences: after a contract is invalidated or revoked, the property obtained from such acts must be returned; where return is impossible or unnecessary, compensation in lieu must be provided; and the party at fault shall compensate the other party for the losses suffered, with all parties sharing corresponding responsibilities if jointly at fault. Fifthly, regarding evidentiary focus: the party claiming invalidity or revocation must bear the burden of proof for facts such as fraud, coercion, collusion, or violation of mandatory provisions, and therefore should preserve evidence such as communication, promotion, and audio recordings during the contract negotiation process. Sixthly, regarding practical tips: before signing a contract, it is necessary to review the parties' qualifications and performance capabilities, and the contract terms should be clear and unambiguous to avoid disguising illegal purposes with legal forms and prevent the contract from being deemed invalid due to violating laws or public order and good customs. In summary, the three essential elements of subject, intent, and content form the basic framework for judging contract validity.
