Well. . . .

I can't speak for anyone else, but my understanding is that, if served, (1) a person would have to obtain his/her own attorney, and that would involve interviewing several in order to find someone who was interested and who had appropriate experience and interest; and (2) paying for defense. This could be very time-consuming and definitely could be very costly.

Then there is the loss of privacy. Be prepared to furnish just about anything that they can get by with ordering, including (almost?) dental records.

I wouldn't want the ordeal. OTOH, if I ever had to fight a lawsuit, I would make d*mned sure that I had the best bulldog of an attorney out there that I could find, and I would be thinking of a counterclaim from the moment the other side involved me.
