There are a couple of lawyers here on the board who will chip in a bit. Also, most lawyers give a free consult of about 20 minutes or so. She might want to talk to one, just to see what she would be up against.

If there is a YWCA or other women's association in her area, they might be able to recommend a good lawyer.

She might want to look at a mediator as opposed to a lawyer as well.

I wish her luck.
