A family member of mine was just on jury duty for a similar case in Seattle. The jury found for the previous owner since the new owner's atty was not able to show that the previous owner's knew about the problem. I realize that this is not the same situation as you, but does show that it's THEIR job to show negligence or deceit from you. Don't help them, don't talk to them, & get an atty if needed. Contact your ins. co for a copy of their assesment of the situation (if they say it's no longer available tell them to get it out of their archeives or wherever, then find out what your state laws are regarding record retainment), your reciepts for fixing the problem (as well as your failed efforts to solve it), and a copy of the disclosure form. Do all correspondance in writing. ps: get a good lawyer who knows about homes and this sort of stuff. A business lawyer or some other sort that doesn't specialize in this would be more of a hindrance than a help.
