The leak upstairs has soaked the ceiling of my house and made it moldy. How can I sue him in court? The property won't tell me the name and phone number upstairs.

The property can't give you the number of the owner upstairs.

First, you let the property management deal with the ceiling problem of your house and see what he says.

Please give up the phone if you are asked to find someone upstairs.

If you want to sue him, you can fill in the building number directly on the defendant without writing your name and phone number.
