[Direct answer]If the seller conceals serious defects in the house, the buyer may, in accordance with Article 577 of the Civil Code on breach of contract liability and Article 615 on the obligation to guarantee quality defects, request repair, price reduction, and compensation; if the defects affect normal living and use or lead to the failure to achieve the purpose of the contract, the buyer may invoke the statutory right of rescission in accordance with Article 563, and demand the return of the house and refund of the purchase price, as well as claim compensation. If the seller knew about the defects before signing the contract and intentionally concealed them, it may also constitute a breach of contractual duty in accordance with Article 500 and bear liability for damages. It is recommended that the buyer record the evidence by video as soon as possible after receiving the house, commission a third-party inspection, and send a written letter to fix the evidence.

I. Problem background and typical scenarios

In second-hand housing transactions, sellers often conceal major defects of the house to facilitate the deal and inflate the price, such as water leakage and mold, structural cracks in the walls, abnormal deaths that have occurred in the house, fires or water damage, properties under seizure or purchase restrictions, and major unfavorable plans in the surrounding area. Buyers often only discover these issues after taking possession of the house, at which point they have already paid the full purchase price or face difficulties in providing evidence. Typical scenarios include: sellers whitewashing or covering up leaks and defects before signing the contract, real estate agents failing to fulfill their obligation to verify the information, abusing the "delivery as is" clause in the contract, and buyers transferring ownership without conducting thorough on-site inspections. The core of such disputes lies in whether the seller violates the obligation to provide warranty for defects and the duty to disclose information truthfully, rather than simply attributing the problem to "the house being of poor quality".

II. Key points of contention

The disputes focus on three aspects: First, whether the defects are "significant" and affect the living or transaction value, determining whether to reduce the price for compensation or terminate the contract; Second, whether the seller "knows and conceals" it. The buyer needs to prove that the seller knew about the defects and that they existed before the contract was signed. It's not enough to simply find the defects after taking possession of the property to hold the seller accountable; Third, the boundaries of the intermediary and the "delivery as-is" clause. A standardized clause stating that "the buyer is aware of the current state of the property" cannot automatically exempt the seller from the obligation to disclose known major defects. In addition, the allocation of the burden of proof, the responsibility for appraisal fees, and the offset between the return of the down payment and compensation in the case of a fully paid purchase price are all practical difficulties that require comprehensive planning before litigation.

III. Professional analysis by Henglue Law Firm

When handling disputes over defects in second-hand houses, Henglu Law Firm's approach is to first determine the "nature of the defects" and then select the "remedial path". For defects that affect the structural safety, such as cracks, recurring water leaks, and unexplained deaths, the firm typically alleges that the seller violated the warranty of defects and the obligation to provide truthful information. There are two remedies: request repair, price reduction, and compensation for decoration and transitional losses under the premise of continued performance; or request contract rescission when the contractual purpose is frustrated. For clauses such as "delivery in its current state" and "with known defects", the lawyer will review whether they are standard clauses, whether the seller fulfilled the obligation to provide adequate warnings and explanations, and whether they exclude the buyer's main rights. According to Articles 496 and 497 of the Civil Code, the lawyer will argue that such clauses do not constitute part of the contract or are invalid. In practice, courts tend to protect bona fide buyers, but require buyers to fulfill their reasonable inspection obligations. Therefore, it is easier to gain support by proving that the seller concealed the defects rather than simply claiming that "the house is not good".

IV. Practical suggestions and legal basis

Legal basis: Article 500 of the Civil Code (effective January 1, 2021) stipulates the liability for breach of contract due to fault in contract negotiation, requiring compensation for intentionally concealing important facts related to the conclusion of the contract or providing false information; Article 577 is a general provision on breach of contract liability; Articles 612 and 615 stipulate the seller's obligation to guarantee the absence of defects in rights and quality; Article 584 defines the scope of damages for breach of contract; Article 563 stipulates the statutory right of rescission. Practical suggestions: Conduct multiple on-site inspections before signing the contract, inspect for leakage during rainy days, and inquire about the history of the house and surrounding planning; require the seller to disclose major defects in writing and incorporate them into the contract; retain video footage of the inspections and communication records; promptly send a letter to fix evidence and apply for appraisal after discovering concealment, to avoid the house being further modified and causing the loss of defects; and, if necessary, hire a lawyer to file a lawsuit.

5. Henglu Law Firm's Reminder

In the second-hand housing transaction, "concealing defects" is not an unsolvable problem, but it depends on evidence and timing. Buyers often make the mistake of only verbally negotiating after receiving the house, delaying for several years, and the defects in the house being irreversible after renovation, ultimately failing to provide evidence. The correct approach is: to stipulate the disclosure of defects and breach of contract liability in the contract, to videotape and store evidence immediately after receiving the house, to entrust professional inspections, to send a written letter demanding liability, and to complete the evidence chain before the dispute enters litigation. At the same time, it is necessary to rationally distinguish between "the seller's attributable concealment" and "normal depreciation and wear and tear", the latter of which is difficult to gain support. If you are currently in a stalemate with the seller over housing defects, it is recommended to consult a professional lawyer as soon as possible and seek help from professionals.Legal services for real estate transactions and construction projectsAndBeijing Henglu Law FirmEvaluate termination, price reduction, or compensation options to avoid missing the best window for evidence collection and legal claims.

VI. Frequently Asked Questions

Q1: If the seller conceals the fact that there's a water leak, can I request a refund and cancel the purchase?

It depends on the severity of the defects and the conditions for contract termination. If the water leakage constitutes a fundamental defect that affects normal living use, or if the seller knew about it before signing the contract and intentionally concealed it, the buyer can claim that the seller violated the warranty obligation for quality defects in Article 615 of the Civil Code and the duty of contractual diligence in Article 500, and request a reduction in the purchase price and compensation for losses. If the defects prevent the contractual purpose from being achieved, the buyer may invoke the statutory right of termination in Article 563 and request to terminate the contract, return the purchase price, and seek compensation. However, for minor water leakage that can be repaired, courts generally support repair or price reduction rather than contract termination. Buyers should keep the viewing records, communication evidence, and professional inspection reports to prove that the defects existed before signing the contract and that the seller was aware of them. If necessary, they should hire a lawyer to assess the feasibility of contract termination to avoid having their lawsuits dismissed due to lack of evidence.

Q2: How to prove that the seller "knowingly" knew that the house had defects?

Evidence can be organized from multiple sources: testimonies from neighbors, property management, and community workers, proving that the defects have existed for a long time and that the seller should have been aware of them; repair records of similar problems in the same community, the seller's previous repair or communication records; the seller's concealment of abnormalities in specific areas before signing the contract (such as repainting to cover mold stains); statements from intermediaries or previous owners; and time-of-formation appraisals issued by housing inspection agencies. In terms of evidentiary standards, the buyer does not need to prove that the seller "admitted it verbally", but only needs to present preponderant evidence to convince the judge that the seller should have been aware of and concealed the defects before signing the contract. When the evidence is weak, the buyer can first apply for a court investigation order to retrieve property and repair files, and then decide whether to initiate a lawsuit for contract termination or compensation to avoid wasting time and effort.

Q3: Can I still claim compensation even though the contract stipulates that "the goods are delivered in their current condition, and the seller is not liable"?

This does not necessarily exempt the seller from liability. If such clauses are provided by the seller without consultation with the buyer, they are deemed standard contractual terms. According to Articles 496 and 497 of the Civil Code, if the provider fails to fulfill the obligation of providing notice or explanation, or if the clauses increase the buyer's responsibilities or exclude the buyer's main rights, the clauses will not become part of the contract or be invalid. Furthermore, the seller has a statutory obligation to truthfully inform the buyer of any major defects known before signing the contract, and cannot exempt themselves from liability in advance by claiming "delivery as is". Courts typically consider such concealment as fraud or breach of contract, and the buyer can still request a price reduction, compensation, or even contract cancellation. However, it is difficult for the buyer to claim the seller's liability for minor defects that were visibly apparent during the inspection and were fully disclosed. Before signing the contract, it is recommended to review such liability exemption clauses item by item, request their deletion or written clarification when necessary, and incorporate the seller's commitments regarding the condition of the property into the main body of the contract.

Q4: How long after discovering a defect can I file a lawsuit without the statute of limitations expiring?

For claims related to defects in second-hand houses, the general statute of limitations is three years, which starts from the date when the buyer knows or should have known that their rights have been infringed and the obligee's obligations have been breached (i.e., when the defects are discovered and the buyer learns that the seller concealed them), rather than the date of the property transfer. However, it's important to note that after discovering the defects, the buyer should promptly fix the evidence and assert their rights. Activities such as sending reminders, issuing legal notices, or filing lawsuits can interrupt the statute of limitations and restart the three-year calculation. If the house has ongoing issues such as persistent leaks that can be repaired, and the losses continue to expand, it's advisable to promptly commission an appraisal to determine the scope of the damages before seeking compensation. Additionally, attention should be paid to special provisions in the contract, such as quality objection periods and inspection periods, to avoid being deemed to have accepted the defects due to exceeding the inspection period. For major concealments, the buyer can assert the seller's fraudulent misrepresentation and exercise the right of rescission, with the limitation period starting from the date of discovery. It's recommended to consult a lawyer as soon as possible after discovering the defects to avoid facing double disadvantages in terms of both the statute of limitations and evidence collection.

Q5: If the seller conceals the defects, can I sue the agent at the same time?

The intermediary can be added as a co-defendant or a third party as appropriate. If the intermediary knows about the major defects of the house but fails to report them truthfully, or even helps the seller conceal them, the buyer can, in accordance with the relevant provisions of the intermediary contract, claim that the intermediary failed to fulfill its obligation to report truthfully, committed faults, and require it to bear corresponding compensation liability. If it constitutes fraud, the buyer can also claim that the intermediary and the seller should bear joint and several liability. However, the intermediary is usually only liable within the scope of "knowing and not disclosing". For situations where the seller intentionally conceals the defects and the intermediary does not know about them even after reasonable verification, the liability is relatively limited. In practice, it is recommended to list the intermediary as a defendant and let the court investigate its performance of the verification obligation. Retaining the intermediary's written explanation and commitment to the house's condition at the time of signing the contract is a key piece of evidence for holding it accountable. If it is missing, it will be difficult to make the intermediary bear the responsibility.
