Yes, we have Title Insurance and I filed a claim.
Did you get a chance to talk to someone from the title insurer on the phone? Did they give you any idea whether they intend to provide you with counsel (a lawyer)? Did they give you any instruction on what to do?
I've asked and got a hearing set for Dec. 16
Unless the lawsuit was filed in small claims court (seems unlikely), you need a lawyer. Trying to represent yourself in any other court is absolutely a losing proposition. Even if you understood the relevant law (sounds like you don't), you'd almost certainly still lose if you don't also understand and follow all the court's rules of procedure.
Just to be sure: you've been sued in a court of law, right? The hearing is in a court, not before a property-tax appeals board or anything like that, right? In which case, is this the first you've heard about this??? Have you been ignoring previous attempts to communicate with you about this issue? If so, that was not smart.
