If the court letter refers to the same accident you had before, I think, you should inform about this letter to your car-insurance company as soon as possible. If the case was already settled down by the insurence agent and still you are getting all these troubles, you may sue her back later on. However, you should not try to tallk to or contact that lady directly or over the phone. I have heard that such an attempt could be taken to charge against you as if you attempted to harass her.

Guys, help him with good advices.
