What reasons can a condo association be sued?

(In America, anyone can pretty much sue anyone for most any reason.)

The association is a corporation. Your governing documents and the state association law govern their responsibilities, limitations and actions.

If you believe -- and have evidence -- that the association's board has acted illegally, you can sue them. You can find an association-savvy attorney willing to take your case, and begin there with your stories, proofs and evidence.

However, in the case of the association, remember that if you are an owner, some of your assessment dollars are being used by the association to defend itself against your suit.
