Welcome to SR So Tired. Glad you found us.
I'm so sorry for all the pain you are feeling and for what you are going through. But you've come to the right place for understanding and support.
I don't have any knowledge about the laws, so I'm sorry that I have nothing to offer you there.
Have you looked into attending some Alanon meetings in your area for yourself? Many people here attend Alanon and have found it to be very beneficial in learning how to deal with another's alcohol related issues.
In any event, please keep coming back and sharing as you feel the need to. I'm sure others will be along shortly to lend their support as well!
