Landlord and tenant don't cooperate with the water leakage upstairs. Who should I find to solve it?

Legal analysis: First of all, you can find a property to deal with, and ask the property to coordinate and solve this matter. Secondly, if the property is neglected in management or the property coordination is ineffective, you can complain to the industry Committee or the owners' meeting. The Industry Committee is required to urge the property, relevant owners and tenants to cooperate with each other to solve the water leakage problem as soon as possible, and claim compensation if there is any loss. Finally, if there is no industry Committee or the urging of the industry Committee has no effect, you can collect evidence and bring a lawsuit to the court, demanding to stop the infringement, restore the original state and compensate for the losses.

Legal basis: Article 188 of the Civil Law of People's Republic of China (PRC) requests the people's court to protect civil rights, and the limitation of action is three years. Where there are other provisions in the law, those provisions shall prevail. The limitation period of action shall be counted from the date when the creditor knows or should know that the right is damaged and the debtor knows it. Where there are other provisions in the law, those provisions shall prevail. However, the people's court shall not protect the rights that have been damaged for more than 20 years. Under special circumstances, the people's court may decide to extend the time according to the application of the obligee.
