Step Mother Harrasment And Forcing For Property Registration

My step mother was acting so caring as she been eyeing on the property my father has.. she started harrassing me and used to trigger me mentally now she is asking my father to register the property by her name.. i suggest my father to give another land which has less sft, but as he is manipulating him , he is agreeing with her to give the property that she is eyeing on, the property is all earned by my father alone... But i dont want him to hand it over to her... Is there any preference of my decision that court could consider??she is also telling to my father to leave us and come separately if not she will live alone or she will divorce my father.. I'm not understanding how to deal with it... N if there's any chance to put my decision in front legally that if any could help me out legally as I'm ( the child of my father) do I have any right to stop from the registration to happen on her name
