Is it illegal not to pay property fees?

Failure to pay property fees is not illegal, but it may constitute a breach of contract. Article 944 of Civil Law 6868: 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.
