Crisc,
I just thought of something else. If you need to take court action, it protects your side so they can't point a finger at you and say the parents never took him to a psych/counselor. Sorry, but they can fight dirty. The psych may in fact be your ammo, backup. For an example: I have a degree in Eng. Ed, worked as a teacher, yet took a part time waitress job while I was beginning actor's training. In the courttoom, their lawyer announced that "his mother is a waitress" and omitted my degree in educ. and that I had been a teacher before I had the kids.
