[Direct answer]In the Beijing area, the agreement signed under deception is not invalid, but can be revoked. According to Article 148 of the Civil Code, if a party uses fraudulent means to make the other party perform a civil legal act against their true intention, the party deceived by the fraud has the right to request revocation; after revocation, the contract shall not take effect from the beginning, and the fraudulently obtained property shall be returned. If losses are caused, the party can also claim compensation. The key points are two: proving "fraud" (deliberately fabricating facts or concealing the truth) and "therefore signing the contract" (causality), and exercising the right of revocation within the one-year exclusionary period.

1. Problem background and typical scenarios

The forms of contract signing under deception are diverse and varied. For example, false profit promises at investment promotion meetings, sellers concealing major defects in the house, franchisers fabricating store sales and profit data, and fake positive reviews generated by online shopping leading to contract signing. Victims often react initially with "This contract was obtained by deception, so it's naturally invalid", but the legal response is more nuanced: the contract can be revoked rather than automatically invalidated, and there are time limits for revocation and evidentiary thresholds to be met.

II. Key points of contention

First, the constitutive elements and forms of evidence of fraud. Second, the determination of causality and significance. Third, the special rules regarding third-party fraud. Fourth, the period of right of rescission and liquidation after rescission.

III. Professional analysis by Henglue Law Firm

First, disassembling the constitutive elements of fraud: 1. Fraudulent intent (knowingly making false statements, or intentionally concealing information subject to disclosure obligations); 2. Fraudulent acts (fabricating facts, concealing the truth, including false statements about product performance, qualifications, or contractual fulfillment capabilities); 3. Causal relationship (the victim making a contractual declaration based on the fraudulent misrepresentation); 4. Breach of true intent. For evidence, common sources include promotional materials, chat records, audio/video recordings, appraisal reports, and statements from co-victims. Oral promises are the most difficult to substantiate, so it’s crucial to systematically preserve pre-contract communication records. Second, practical review of the causal relationship: Even if fraud is established, courts will assess whether the victim’s contractual decision was actually influenced by the fraud—if the transaction background itself was attractive and the misleading information was merely incidental, rescission may not be supported. Conversely, if the core selling points (e.g., yield rates, product origin, functional claims) were fabricated and the causal chain is clear, rescission is more likely to succeed. Concealed matters falling within statutory or contractual disclosure obligations (e.g., property leaks, vehicle accident history, corporate litigation) constitute fraud even if silent, with legal interpretation guided by current laws and judicial rulings. Third, rules on third-party fraud: If the fraud originates from a third party (e.g., agents, intermediaries) outside the contract, and the contractual counterparty knew or should have known about the fraud, the victim may rescind the contract. If the counterparty was unaware, the contract remains valid, and losses must be recovered from the fraudulent third party. Therefore, verifying the counterparty’s knowledge of the agent’s information at the time of contracting directly impacts remedial options. Fourth, timeframes and liquidation: - The right to rescind must be exercised within one year from the date the rescission grounds become known or should have been known; - For major misunderstandings, the rescission period is 90 days; - Unexercised rights within five years of the act’s occurrence are extinguished; - After contract rescission, the contract is void ab initio. Return of paid property, compensation for non-returnable items, and fraudulent party’s liability for contractual losses apply; - For large-scale cases involving contract fraud, criminal reporting and civil rescission can proceed concurrently, with criminal recovery results linking to civil compensation—first determining legal nature (civil fraud or criminal fraud), then establishing procedures is the standard approach in such cases.

IV. Practical suggestions and legal basis

The first step is to immediately secure all evidence of publicity, communication, and payment and seal the originals; the second step is to send a notice of revocation or file a lawsuit for revocation within the one-year statute of limitations; the third step is to evaluate the parallel structure of criminal reporting and civil remedies; and the fourth step is to apply for property preservation simultaneously after successful revocation to prevent the return from failing. The main legal basis: Articles 148, 149, 152, and 157 of the Civil Code of the People's Republic of China, and the provisions of the Criminal Law on contract fraud; the specific application shall be subject to the currently effective provisions.

VI. Frequently Asked Questions

Q1: Can I win the lawsuit if I was deceived into signing a contract?

If the evidence of fraud is sufficient, the causal relationship is clear, and the fraud occurred within the statute of limitations, the rate of support for revocation is higher; however, it's more difficult to revoke the contract if there are only verbal promises without fixed evidence.

Q2: What evidence do I need to prepare?

Promotional and commitment materials, communication records and recordings, payment receipts, contract texts, appraisal reports, and the testimonies of other victims or verdicts in related cases.

Q3: How much does it cost to litigate a case?

The litigation fees shall be charged according to the subject matter of the refund; the notarization and appraisal fees shall be charged separately, and shall be prepaid by the applicant, and the losing party shall bear them in proportion.

Q4: How long does the cancellation process take?

Pre-litigation consultation can take several weeks at the earliest; first-instance litigation usually takes several months, and the period for linking with criminal proceedings will be correspondingly extended.

Q5: What should I do first if I find out I've been scammed?

On that day, we fixed all the evidence and the other party's identity information, calculated the statute of limitations, and then decided whether to initiate civil revocation proceedings, report the case to the police, or pursue a dual-track approach.
