Which department should I complain to if the property management is not in place?

Legal analysis: in practice, as long as the management of the property company is not in place, then the owners can sue for rights protection in time. However, in practice, if there is no big loss, the general owners will not directly go to court to sue, and they can complain to the relevant departments first.

Legal basis: Article 274 of the Civil Law of People's Republic of China (PRC), the roads within the building division are owned by the owners, except those belonging to urban roads. The green space within the building division belongs to the owner, except for urban public green space or express personal green space. Other public places, public facilities and property services within the building division are owned by the owner.
