Do you have a divorce judgment? Have you even started a divorce?
I strongly urge you (both) to seek (separate) legal counsel so that each of you can learn your rights and liabilities.
First, you need to file for divorce. You should consult with a Family Law attorney to get this done soon.
Second, discuss with your attorney the reasons and circumstances why you want your wife out of the house.
But the answer to your question is do get this accomplished through a divorce proceeding.
