Do you know why your Association has joined the suit?

Does the Association have meetings with their attorney present in order to keep the members up to date and can you ask questions?

And if the Association should win the suit, can they then sue the member for costs? If so, and should he not be able to pay, can a lien then be applied to his property?

At least some of the answers to your questions would vary state by state and would depend on the particulars of your Association's rules. Your questions and concerns should be addressed by your Association's attorney.
