Divorcing a Sociopath

Lawyer Nancy R. Van Tine sets forth the DSMIV definition of a sociopath on her blog, Massachusetts Divorce Law Monitor.  She says that about 4% of the population fits this description.  Divorce is hard enough with sane people.  Imagine litigating a divorce with a sociopath who is deceitful, aggressive, irritable and remorseless, among other things.  Sounds like your ex?
