How can I get my alcoholic wife out of our house?

If she is on title to the home--then you have no right to kick her out of the house.  Domestic violence restraining orders have a mechanism to get a "kick-out" order, but you can only use them if there has been some sort of abuse or threat of abuse by her.  You should consult with a local family law attorney about the ramifications of moving out and ask specific questions about how Epstein  and Watts would apply here.

Best of luck.
