Advice for my mother

Hello Sir, I want to know about my mom. She is 67years old living in India. My father is harassing her by yelling on her from last 10years. He is not earning anything. My brother and myself are living in Dubai. My brother is sending 3000rs to my father every month apart from the household expenses of 35000everymonth to my mom. Then also my father is continuously torturing my mom. He is saying that he will take all of us to Court. Also he has adopted some female lawyer as his daughter and now he is harassing all of us . We are living to Dubai and it is not possible for us to live job and come there. Is there any solution that could be done to this situation We are in a very bad condition as we have also asked our relatives to help us but no one is coming forward ss my father yells on everyone. Everyone is afraid of him. Also the home has been purchased by my brother but my father says it is his home. He is taking advantage of this whole situation where me and my brother are here in dubai giving us dhamkis that he will cancel our passports and giving dhamkis to mom for the same that i will put your kids in the jail. Please advice what can be done? We don't want to waste our time in legal proceedings as we need to earn for our future but also we need our mom tobe safe.
