Property dispute in divorce

Hello experts, I am married for 3 years with a working wife. She earns an equa salary as me. We are headed for a divorce now as she wants me to break all connections with my parents. We have moved out to a separate place now. But hasnt helped much. I have a flat purchased prior to marriage jointly with my father where we all were satying together befor I moved out one month ago. In the event of divorce, do I need to give a share in the flat to my wife? Firstly, do I need to give any maintenance to my wife if she is earning same as me. Your thoughts on this would be appreciated.
