Is it legal for the property to increase the property fee without authorization?

According to Article 4 1 of the Property Management Regulations, property service charges should follow the principles of reasonableness, openness, and adaptation of charges to service levels, and distinguish the nature and characteristics of different properties. Owners and property service enterprises shall, in accordance with the measures for charging property services formulated by the competent price department of the State Council in conjunction with the competent construction administrative department of the State Council, stipulate in the property service contract. In this regard, Article 5 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Specific Application of Law in the Trial of Property Service Disputes further stipulates that if a property service enterprise violates the provisions of the property service contract or laws, regulations and departmental rules, it arbitrarily expands the scope of fees, raises the standard of fees or charges repeatedly, and the owner raises a defense on the grounds of illegal fees, the people's court shall support it. If the owner requests the realty service enterprise to refund the illegal fees it has collected, the people's court shall support it. Therefore, if the property management company charges in violation of regulations, the owner can raise a defense and refuse to pay. If the owners think that the property charges are unreasonable, they can report to the property company through the owners' committee, so that the property company can come up with a reasonable charging standard. If the property management company can't come up with a reasonable basis for charging, the owner has the right to refuse to pay. In line with the property fee standards and laws and regulations, the owners should pay in time. If the property fee is not paid for a long time, the property will sue the owners who have not paid the fee, and the result of the prosecution is to make up the property fee. Under normal circumstances, even if the property itself is not in place, in order to protect the property and prevent other communities from following suit, the law will tend to the property side. As for the place where the property is not in place, it is recommended that the owner leave time and evidence with his camera and mobile phone in case of emergency.
