[Direct answer]In the Beijing area, if the buyer discovers illegal buildings in the house after the transfer of ownership, the buyer can legally claim to rescind the contract, return the purchase price, and seek compensation. According to Article 563 of the Civil Code of the People's Republic of China (effective January 1, 2021), if a party breaches the contract and causes the contractual purpose to be unattainable, the other party may rescind the contract; Article 597 stipulates that if the seller fails to obtain the right to dispose of the subject matter and causes the ownership of the subject matter to be untransferable, the buyer may rescind the contract and request compensation. The illegal buildings face orders to demolish or cannot be legally registered, which directly affects the use value of the house and the safety of the transaction. If the seller fails to fulfill the obligation of disclosure and warranty for defects, it constitutes a breach of contract. It is recommended to fix the evidence of the illegal buildings as soon as possible, and file a lawsuit within the three-year statute of limitations to claim for returning the house and refunding the purchase price or seeking compensation for the price difference.

1. Problem background and typical scenarios

In second-hand housing transactions, problems with illegal buildings often emerge in large numbers after the transfer of ownership: buyers may be stopped by property management or urban management authorities during renovations, only to discover that the expanded parts lack planning permits; or they may find out that the house has a record of illegal construction when applying for renovation registration or reselling it, which prevents them from passing the review. Typical scenarios include: adding floors to rooftops, expanding basements, extending balconies, and illegally building courtyards. Sellers may deliberately conceal or even lie by claiming that "there are no historical issues", while real estate agents fail to verify the records of illegal construction. Such houses may not only be ordered to be demolished and fined, but also directly affect loan assessments and subsequent resales. Some buyers have already paid the full purchase price and completed the transfer of ownership, making it even more costly for them to protect their rights afterwards. For cases involving the review of housing project compliance, relevant departments can cooperate with each other to address these issues.Legal services for real estate transactions and construction projectsCarry out a professional verification.

II. Key points of contention

There are three key points of contention. Firstly, whether the illegal construction constitutes a fundamental breach of contract: if the proportion of illegal construction is relatively high, affects the safety of the main body, or is explicitly required to be demolished by the competent authority, it is generally determined that the contractual purpose cannot be achieved; for a small proportion of ancillary structures, the court may only support the repair costs or appropriate compensation. Secondly, the seller's fault and disclosure obligation: whether the illegal construction occurred during the seller's ownership period, whether the seller was aware of it, and whether there was a false statement at the time of signing the contract determine the severity of the liability. Thirdly, the connection between administrative handling and civil liability: if the urban and rural planning competent authority has ordered the demolition, it is easier for the buyer to claim to rescind the contract and return the house and gain support; if the administrative handling has not yet started, the buyer can also claim rights based on the warranty of defects and fraud. If the seller colludes with the intermediary to conceal the information, it may constitute fraud, and if necessary, legal assistance should be sought.Criminal defense and criminal case filing servicesEvaluate the parallel criminal and civil litigation program.

III. Professional analysis by Hengluo Law Firm

Li Yonghui, a lawyer from Hengluo Law Firm, once handled a dispute over a house purchase contract. Company A needed a loan due to the funding crunch of its affiliated company, so it used the name of employee Zhang * who had continuously paid social insurance for five years to sign the "Beijing City Second-hand House Purchase Contract", selling a 262.05-square-meter house in Chaoyang District to Zhang * for 7.3374 million yuan. The contract stipulated that Zhang * would pay a down payment of 2.5774 million yuan and the remaining 4.4 million yuan would be financed by a mortgage and transferred to Company A's account. However, after Zhang * took away the property certificate and refused to cooperate with the transfer of ownership, Company A sued to confirm the invalidity of the contract and return the house. The first-instance court dismissed the case due to insufficient evidence. During the second-instance trial, Li Yonghui reconstructed the evidence chain involving the flow of funds, the possession of title certificates and fees, and the agency agreement, proving that the parties did not have a genuine purchase agreement. As a result, the second-instance court reversed the first-instance judgment and confirmed the invalidity of the contract, restoring the registration of the house to Company A's name. This case shows that disputes over the ownership and legality of houses often emerge after payment and transfer of ownership, and the completeness of the evidence chain directly determines the success or failure of the litigation. The case was handled by Beijing Hengluo Law Firm.Li YonghuiThe attorney (practice certificate number: 11101199611955812, subject to the certificate issued by the judicial administrative organ) acts as the agent.

IV. Practical suggestions and legal basis

The core basis is Article 563 (Statutory Right of Rescission), Article 577 (Liability for Breach of Contract), Article 597 (Dealing with the Situation Where the Right of Disposition Is Lacking and the Ownership Cannot Be Transferred), and Article 148 (Fraudulent Revocation) of the Civil Code of the People's Republic of China (effective on January 1, 2021), as well as Article 64 of the Urban and Rural Planning Law of the People's Republic of China (amended on April 23, 2019), which stipulates that buildings that have not obtained construction project planning permits or have not been constructed in accordance with the provisions of the construction project planning permits shall be ordered to stop construction, rectify within a specified period, fined, or demolished. Practical suggestions: First, verify the housing planning and construction records before signing the contract and require the seller to make a written commitment that there are no illegal buildings; Second, immediately fix the scene photos, documents from the competent authorities, and law enforcement records if any illegal buildings are found; Third, assess the proportion of illegal buildings and the consequences of demolition, and choose the path of rescinding the contract, refunding the house price, or compensating for the price difference; Fourth, quantify the depreciation of the house value through an appraisal agency. For the recovery of the price difference losses, it can be combined with other legal remedies.Creditor-debtor relations and enforcement case servicesAdvance the implementation.

5. Hengluo Law Firm's Reminder

Illegal buildings are a "serious problem" for houses: they may be demolished administratively and affect the validity of contracts and compensation in civil law. Please pay attention to three points: First, determine the nature of the illegal building. Confirm the scope of the illegal building and the consequences of the demolition through planning departments and law enforcement documents, and distinguish between the main illegal buildings and auxiliary structures; Second, take early action. Sue within the three-year statute of limitations, and at the same time, pay attention to the progress of administrative demolition to strengthen the legitimacy of terminating the contract through law enforcement documents; Third, keep a good chain of evidence, including contracts, commitments, payment receipts, images of the illegal buildings, and documents from the competent departments. If the property has been transferred, you can claim to terminate the contract, reverse the registration, and claim compensation for depreciation losses.

VI. Frequently Asked Questions

Q1: If illegal construction is discovered after the transfer of ownership, is there a good chance of winning a lawsuit to rescind the contract and get the house back?

It depends on the severity of the illegal construction. If the illegal construction accounts for a large proportion, affects the safety of the main structure of the house, or is ordered to be demolished by the competent department and cannot be rectified, it is generally determined that the house has major defects and the contractual purpose cannot be achieved. According to Articles 563 and 597 of the Civil Code, if the buyer claims to rescind the contract, return the house price, and compensate for losses, there is a high probability of obtaining support; if it is only a minor auxiliary construction that can be rectified, the court may only support the repair costs or appropriate compensation, and the claim to rescind the contract is more difficult to establish. In addition, if it can be proved that the seller made false promises knowing about the illegal construction at the time of signing the contract, the buyer can claim to rescind the contract on the grounds of fraud according to Article 148. It is recommended to obtain a qualification document from the planning or law enforcement department before suing.

Q2: What evidence do I need to prepare to protect my rights against illegal construction?

The core evidence includes: the house sale and purchase contract and supplementary agreement (proving the seller's commitment and quality agreement), the seller's chat records or written promises regarding no illegal construction, photos and videos of the current state of the house (proving the scope of illegal construction), the order for demolition issued by the competent urban and rural planning departments or comprehensive law enforcement departments, the documents for rectification within a specified time limit and punishment decisions, records of blocked property or decoration registration, and the house evaluation report (proving the depreciation of value). The organization of evidence should focus on "the existence of illegal construction - the seller's knowledge or should have known - the impact on use and value - the amount of loss". For possible lost scenes and documents, it is recommended to preserve them through notarization and apply to the registration and planning departments to retrieve historical construction filing archives.

Q3: For the lawsuit against unauthorized construction and eviction, what are the approximate costs of attorney fees and litigation fees?

The litigation fees are calculated according to the "Measures for the Payment of Litigation Costs" (implemented on April 1, 2007) and accumulated in stages based on the amount of the litigation request. In cases involving check-out disputes, the fees are usually calculated based on the purchase price claimed for return. When the amount is high, the fee rate decreases, and the losing party bears the fees or shares them according to the proportion of victory and defeat. For applications for property preservation and house appraisal, additional preservation fees and appraisal fees need to be paid. There is no unified standard for attorney's fees, which are usually charged according to the proportion of the subject matter or on a per-case basis. The fees involved in appraisal, second-instance litigation, and enforcement will increase accordingly. It is recommended to calculate before suing: the net income that can be claimed for the return of the house price, interest, and depreciation compensation, deducting the litigation fees, attorney's fees, and appraisal fees, and checking the seller's repayment ability. If necessary, apply for preservation first and then initiate the full litigation process.

Q4: How long does it usually take to litigate against unauthorized construction and evict the tenants?

The first-instance ordinary procedure generally concludes within six months, and the summary procedure within three months; such cases often require retrieving planning and construction archives, and if necessary, conducting a housing value assessment. The period will be extended accordingly during the appraisal and investigation. If either party appeals, the second-instance procedure generally takes three months. After the judgment takes effect, the return of the housing payment requires the other party to fulfill their obligations. If the other party fails to do so, the case will enter the forced execution phase, and the duration will depend on their financial status. Overall, cases with solid evidence and no need for appraisal can be concluded within three to six months, while those involving appraisal and identification may take nearly a year. It is recommended to apply for property preservation simultaneously during the litigation to prevent the seller from transferring the housing payment or other assets and shorten the actual recovery time of the payment.

Q5: If I find that there are illegal buildings in the house, what should I do first?

It is recommended to follow four steps: First, fix the evidence by taking panoramic and detailed photos of the illegal construction sites, and collect property notices and records of obstacles in decoration registration; Second, obtain a qualitative determination by reporting to the competent urban and rural planning departments or comprehensive law enforcement departments to obtain documents ordering demolition and rectification within a specified time limit, clarifying the scope of the illegal construction and the consequences of the handling; Third, make a written appeal by sending a letter to the seller to claim the rescission of the contract, the return of the house price and compensation, and keep the proof of delivery, while requiring the intermediary to assist; Fourth, evaluate and sue within the three-year statute of limitations to claim the rescission of the contract, the reversal of registration and compensation for depreciation losses, and apply for property preservation as needed. It is crucial not to engage in intense conflicts with the seller before obtaining evidence, nor to wait until the administrative process is completed before seeking legal protection.
