Does the property management have the right to dismantle the security window installed by the owner? In addition, our community has not signed the relevant property contract!

In the absence of relevant contracts, this is certainly unreasonable. If the property needs rectification. No problem. You ask him for the certificate issued by the state, or the formalities. If you can get it out. Then there is nothing we can do. . After all, we are a vulnerable group. If you can't get it out, Ignore him. If he wants to open it, sue him directly. . .
