I am a pray of  domestic violence…..Truly speaking not me but my sister is a pray to this….This thing has been extended towards threatening my parents…..My sister’s husband seems to know the fact that it is not easy to prove the issue in court….So he is challenging us to go to court and then he will show what can be done…I need a help in this situation…Who can help us and how? We are based in Kolkata WB…
