Is it illegal for the property to cut off power privately?

Legal analysis: illegal. The owner signs a contract with the water supply and power supply company, and the property management company is not a party to the contract. If it is illegal to cut off water and electricity without authorization because the owner defaults on the property fee or for other reasons, resulting in economic losses, the property company needs to make economic compensation. If you owe the property fee, you can pay the liquidated damages normally. If the property is cut off without authorization, the owner can sue for rights protection.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 944 The owner shall pay the property fee to the property service provider as agreed. If the property service provider has provided services in accordance with the agreement and relevant regulations, the owner shall not refuse to pay the property fee on the grounds that he has not accepted or does not need to accept the relevant property services. If the owner fails to pay the property fee within the time limit in violation of the agreement, the property service provider may urge him to pay it within a reasonable period of time; If the payment is not made within a reasonable period, the property service provider may bring a lawsuit or apply for arbitration. The property service provider shall not stop power supply, water supply, heat supply and gas supply to demand payment of property fees.
