Domestic violence case

Hello... I am a govt employee and my husband too. Unfortunately my son died last month.. We r belonging from a Muslim family. My son had one son and a daughter. After my son's death my daughter in law and her family tried to force us to make a will. We told them that we will do the Will in the name of my grand son and grand daughter. But they refused that. They told me to do the will in the name of my daughter in law 's. Some how we managed to convince them at that time. After some day they told us that my bahu want to go to her parents home .we agree and told her to come soon. After going to her parents home she didn't even call me if I did then she was less interested to talk to us. Any way.. Her father regularly called to our sarpanch and told him to make a will in favour of my daughter in law.. My sarpanch told us that we need a family discussion.. We again called my bahu.. She told that she will not come. My husband said OK "agar aap aana chahate ho to tumhare taraf se kuch well wisher leke aana because we really need a discussion. Then she abused us. Next day when we were at office she came with her mother and sister and made a lot of drama.. Said that mere sasur ne mujhe dhakke marke ghar se nikal diya. After that her mother admitted her to hospital. Not only that they told doctor that my bahu is pregnant. That is false also. So we are worried. How dangerous her family is. So my question is.. Kya woh domestic violence case or koi aur case hamare against Kar sakti hai
