January -
I was in simular situations and a domestic violence agency helped me.
Its nationwide and every state has it and there are many, many shelters in every state. Be it the person just needs a place to hide for a bit or a total relocation plan.
Not only do they offer counseling for many forms of domestic violence - relatives, friends, lovers, spousal you name it they work with it - but theyu also know the law and court process and go to court with their clients.
The nation wide number is
1-800-799 -SAFE (1-800-799-7233)
They will be able to put you in touch with the domestic violence office that covers your area.
Domestic Voilence first helped me back in the 1980's and no matter what state I am in when I need them I have never had anything but the best from their agencies.
There is also a great website
http://www.WomansLaw.org which has come in handy many times for me.
Good luck and take care.
