Can I file a harassment complaint against my mother in law and brother in law

I am married for 11 years and have a son who is 8 years old. My husband is a Brahman and I am from a lower cast (obc). Although we are happily married, and our father in law supported us, we were asked to move out of the family home the day we got married by my husband's mother and two brothers. We have been living separate from then on. My husband was running a small by successful business, but was very stressful on him. When I was pregnant we decided to move to my father in laws farm (his self earnt property)and start dairy farming. We pooled together all our savings and with a loan from bank(land as collateral by my FIL) we developed the abandoned farm, built a house to stay and also built a shed to house the live stock. Everything was fine until my father in law was alive. He was staying with us in the farm. From the day he died about four years ago, my mother in law has taken over the farm which is now generating an annual income and has been harassing my husband with false police complaints. Although we have filed a partition suite they are prolonging the case intentionally with unsubstantiated claims. Now every time she and her son (my brother in law)gets an opportunity in any family gathering she defames me by blaming my cast and below average looks(compared to her other two daughters-in-law) for our misfortune and financial duress. Can I file a harassment complaint against her and my brother in law
