[Direct answer]In the Beijing area, if water leakage from an upstairs unit causes damage to one's own property, a claim for compensation can be made against the upstairs owner based on the principle of neighborly relations and tort liability. According to Articles 288 and 1165 of the Civil Code of the People's Republic of China (effective January 1, 2021), property rights holders must not endanger the safety of neighboring properties, and those who infringe upon others' civil rights and interests through negligence shall bear tort liability. The claim process involves first collecting evidence (repair records, on-site photos, damage lists, and repair receipts), then negotiating with the upstairs owner and the property management company. If no agreement is reached, a lawsuit can be filed after an appraisal of the cause of the water leakage and the amount of damages, seeking to stop the infringement, repair the damage, and obtain compensation. Action guidance: First, take photos and keep evidence; then send a written notice; finally, negotiate compensation or file a lawsuit. It is strictly prohibited to damage the scene on one's own initiative.

I. Problem background and typical scenarios

Leaks from upstairs are one of the most common forms of neighborly infringement in high-rise residential buildings. Typical scenarios include: burst water pipes upstairs, backflow from floor drains flooding the ceilings and floors below; improper drainage from balcony washing machines causing long-term water seepage; poor waterproofing after renovation leading to dampened walls on rainy days; and long-term unoccupied upstairs units with aging pipes causing seepage and leaks that are difficult to detect in time. Many homeowners' first reaction is to impulsively confront the upstairs residents or pry up the floor tiles without notice, which may even destroy the evidence of the cause. The core of such disputes lies in attributing the cause of the leak and determining the amount of damages.

II. Key points of contention

The dispute focuses on four points. Firstly, the subject of liability: Water leakage stems from improper use of the exclusive parts of the upstairs unit or aging facilities, and the upstairs owner is generally responsible. If it involves shared pipes and the property management fails to fulfill its maintenance obligations, the property management may share responsibility. Secondly, the causality: It is necessary to prove that there is a direct connection between the water leakage and the losses suffered by the downstairs unit. The upstairs unit often defends itself by saying "it's not my fault". Thirdly, the scope of losses: Whether the costs of repairing soaked furniture, floors, and walls, as well as reasonable rental losses during the recovery period, can be included. Fourthly, the burden of proof: The injured party needs to initially prove the damage and its cause. If the cause is unclear, an appraisal can be applied for. In the judicial practice of the Beijing area, on-site photos and property repair records are key factors in determining the allocation of liability.

III. Professional analysis by Henglue Lawyers

The quality defects of the project and the responsibility for repairs are frequent disputes in construction and real estate disputes, and the evidentiary logic of these disputes is consistent with that of water leakage claims. A construction contract dispute handled by Attorney Li Yonghui fully demonstrated the trial logic of quality defenses and evidentiary responsibilities. On May 15, 2023, A (Beijing) Construction Engineering Co., Ltd. and Beijing B Engineering Co., Ltd. signed the "Beijing Municipal Housing Construction and Municipal Infrastructure Engineering Labor Subcontracting Contract", which stipulated that A Company would undertake the HVAC project of a new commercial project in Jinshan District, Shanghai City. The estimated total contract price, including taxes, was 5,300,000.19 yuan. As of January 2025, A Company had completed a total estimated project volume of 4,939,806 yuan, accounting for 96% of the total contract price, but B Company only paid 1,680,000 yuan and offset part of the project payment with the house. B Company argued that the project had quality problems such as pipe leakage and rust and commissioned a third party to rectify them, claiming to deduct the rectification costs. Attorney Li Yonghui pointed out that the commercial plaza where the project was located had been opened and put into use in December 2025. According to Article 14 of the "Interpretation of the Supreme People's Court on Legal Issues Applicable to the Trial of Construction Contract Disputes" (effective January 1, 2021), if the employer uses the construction project without completing the acceptance, the project is deemed to have been completed and the payment conditions are satisfied. Although B Company claimed quality defects, it failed to form a closed chain of evidence sufficient to counter the payment obligation. The court adopted the lawyer's opinion and ordered B Company to pay the remaining project payment of 1,110,574.35 yuan and the overdue interest. This case reminds us that whether it is project leakage or neighboring leakage, the claimant needs to build a complete evidence chain with repair reports, inspections, and invoices, otherwise the defense will be difficult to establish.

5. Henglue Law Firm's Reminder

When making a claim for water leakage, it is most important to avoid "destroying the scene and handling the matter emotionally". If you disassemble and modify the facilities or expand the scope of the construction without notifying the upstairs neighbor, it may not only destroy the evidence of the cause of the leakage, but also make the scope of the loss unclear. It is recommended to preserve the evidence in the first time, invite a third party to witness or appraise, and put the three matters of "who leaked, how much leaked, and how much damage was caused" in writing. At the same time, pay attention to the responsibility of the communal pipes of the property. If it belongs to the public area and the property management is negligent in maintenance, you can claim compensation for it together.

VI. Frequently Asked Questions

Q1: The upstairs neighbor's apartment leaks water. Can I make him pay for the damages for sure?

Whether compensation can be obtained depends on the evidence and determination of fault, rather than the assumption that "the upstairs neighbor must compensate". If it is proven that the water leakage originates from improper use of the exclusive area or aging facilities on the upper floor and causes actual losses, the upstairs owner should generally bear the responsibility for repair and compensation; if it belongs to public pipes and the property maintenance is inadequate, the property may also be held liable. The outcome of the case depends on the evidence and the court's determination, and no lawyer can unilaterally guarantee the amount of compensation. Thoroughly documenting the repair request, photos, and appraisals is the foundation for winning the case.

Q2: What evidence do I need to prepare for a claim?

The four most important types of evidence are: first, repair and notification records, property work orders, text messages, WeChat messages, and call recordings; second, on-site evidence, including photos and videos with time stamps, which record the leakage points and the extent of the damage; third, proof of losses, including purchase invoices for the repair of soaked furniture, floors, and walls, repair contracts, and payment records; fourth, proof of the cause and amount of the losses, which may require an appraisal report issued by a qualified institution. The more complete the evidence is, the easier it is to determine the responsibilities and the amount of compensation.

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

The case acceptance fee shall be paid in accordance with the "Measures for the Payment of Litigation Costs" (State Council Decree No. 481, implemented on April 1, 2007), which stipulates that the fee shall be paid in stages based on the amount of the litigation request. The fee for summary procedures shall be halved, and the fee for settlement through mediation shall be halved. If the applicant requests an appraisal of the cause of the water leakage or the losses, an additional appraisal fee shall be prepaid, the amount of which shall vary with the subject matter and the appraisal items. Lawyer's fees shall be determined through consultation between the law firm and the client, and there is no unified government pricing. Providing sufficient evidence and promoting mediation before litigation is usually more cost-effective than litigating all the way through.

Q4: How long does it usually take from detecting a water leak to receiving compensation?

For cases where both parties cooperate and the amount is clear, they can be resolved through negotiation or mediation within a few weeks. For cases that proceed to litigation, the first-instance summary procedure will be concluded within three months, and the ordinary procedure within six months. If appraisal is required, the period will be extended accordingly, and the overall process often takes several months to more than a year. For similar neighboring water leakage disputes in Beijing, the appraisal process is often a time bottleneck. It is recommended to fix the scene and choose a good appraisal institution as soon as possible to avoid delays leading to the loss of evidence.

Q5: If the upstairs neighbor refuses to cooperate and refuses to compensate, how can I protect my rights?

There are three steps to take: First, continuously send written reminders and request the property management and the community to provide mediation records, in order to provide evidence of the other party's passive response; Second, entrust a qualified institution to appraise the cause of the water leakage and the amount of the losses, quantifying the dispute; Third, bring a lawsuit to the court where the house is located with complete evidence, claiming to stop the infringement, remove the obstacles, repair the damage, and compensate for the losses. If the other party still fails to perform after the judgment takes effect, the plaintiff can apply for forced execution.

The above answer is based on the judicial practice in Beijing. The adjudication guidelines in other provinces and cities may vary. For specific cases, please refer to the local rules and evidence situation.
