Filing divorce

Hello, my sister,my mother and i were forcefully thrown out of our own house by my father and his brothers after a night long fight where they threatened us with murder and abuse. we left the house next day with few of our belongings to save our life. Its been 3 months since that day, we are living in a separate house on rent with no income as my mother is housewife and me and my sister are students. We have not gotten any money from my father who makes multiple calls and brings his brothers with him to fight with us whenever he feels. We want divorce but theyre manipulative people who dont want to give even single coin and are saying we left the house with a lot of cash and gold. They are spreading bad rumors about us to their relatives and area people and threatening to file case against us. What can be done in this situation? What kind of case can they file on us, or are they simply threatening? Should we file for divorce or wait for them to file? Is there any advantage to them if we file for divorce? We have very little saving and no source of income.
