Law regarding disowning daugther in law and son

I have a question regarding the disowning law, my wife is very quarrelsome and she not at all cares about my old age parents , neither she is in good terms with me, in nut shell she is not at all in good terms with any of the family member including her husband ! now my father is planning to file legal suite against me just to expel my wife from his house, he says once the son is disowned his wife is automatically disowned and he has already made it public through newspapers. My father has made the property of his own, its not an ancestral property . My father is doing all this just to safeguard themselves and to get rid from my wife, I am with my father and I know that he is doing right thing, his allegations are right as my wife doesn't look after my old age parents and she doesn't even cook food for them either and she has nothing to do with my parents and her husband (me), however despite of all this, she still wants to live in the property built by my father . I have two kids also, a baby boy and a baby girl. Now my question is, if the son is disowned can the daughter in law still claim on property ? Dose she has any legal authority to claim the property rights build by my father ? and lets say she plans to put a trap and make false allegation of dowry in that case will she be staying in my parents house till the time the dowry case is not settled ? Because, we think that she might try to make a false case of dowry against us and on top of everything what in case she commits suicide and blame my parents and myself in this case ?
