I agree with some of the answers you received. But next time be more specific and articulate. What does "lawyer contacted" mean. Why not say the lawyer who will represent me or us is out of town--if that indeed is the case. If on the other hand you are talking about an out-of-state attorney who is representing a few people at the same time, still I feel you need to be accompanied by legal counsel.
And whether you will be accompanied by a lawyer, or not, you should be present at that court.
Don't ever shy from your rights. And as to you not being good at talking in public, don't even bother thinking that. Just tell yourself "I will be myself, no matter what. Even if my words don't come out fluent. Even if I do forget to mention something. This is my case and my situation and I will stand up for it!"
It all depends.....have you advised the Realtor Office of the situation? Maybe all the information was left in their hands as potention clients of the firm. Hopefully he just left and tossed your information out without thinking of using that information to screw you guys over. Good luck with this one!
