Family dispute by elder brother by misusing the provision of law

I am salaried employee worked almost 10 year outside kolkata of my total 17 years service. Recently I came to know that my father has directly paid the amounts for purchase of property in the name of my elder brother and his wife name( Most of the property in the name of his wife). My elder brother does have any income. His wife was also housewife till 2013. I always paid money and everything to my father. My father spent a huge sum to start business in the name of my brothers wife in 2013. When I came to know my elder brother using my father filed a false case of theft in police and thrown me out of family and also taken gift of balance property from my mother. I want to file lawsuit or PIL/SLP against such discrimination of succession / inheritance law through which parents or brothers can misuse the act to get property. My father and brother has abused my wife. The act is brutal and need to be changed which gives wrong persons to abuse other in the name of power given to them. Plea
