HelloI own a condo in NJ and I've had many many leaks from the condo. upstairs. This is causing damage to my condo: mold, drywall damage, etc.

Not really a personal injury issue but a property damage claim. First question I would ask is whether you had insurance? Also how many notices did you send to the condo association? You have the right to sue, but everything is subject to proof both in terms of the cause of the damage to your property and the amount in terms of the current value of the items you claim were destroyed. If you like, you can call my office tomorrow. 973-246-9659
