Some advice?

Was just looking for some opinions and what to do. My wife and I have been circling the drain of divorce for some time. She has recently become verbally abusive to the point I just don't speak in my own household. I am finally going to take steps and contact a divorce lawyer. I was wondering from personal experience or professional opinions about a few things; 1. Our house is in neither of our names and is currently owned by my mother with no agreement. I've paid all utilities and payments towards her. What ownership does she have towards it? 2. Our finances have always been separate with separate bank accounts. My money has always been used to pay all the bills/car insurance. Hers has been used for groceries and that's about it. She also has made more than me the past 2 years according to our W-2. Any options/opinions on what will be done there? 3. We have no children so there is no issues there, what other things should I ask the lawyer?
