Domestic violence

I had an intercaste marriage and since then my parents and elder sis is having problems with me. This Jan 31st, had my second delivery and have twins. My mother had given alot of mental pressure during my pregnancy period. And she stays with me (house built by me and my husband but my parents have right on the land). My mother stays with me as she is having problems with my dad. The house my parents build is given to my elder sis and dad is living there. These house are within a one house difference. Now, even after my delivery she is continuing her verbal harassment and I told her to go stay with sis and dad alteast for 6 month period. But she refuses to go and claiming right on my house. Her harassment is affecting me emotionally. As my dad is having pension, he is the who should be taking care of her right? And is there any legal provision as a feeding mother to tell my mother to go from my home alteast for a 6 months time so that I can emotionally stable and get peace of mind to take care of my kids?
