Pressurized into giving my salary to my parents by them,my brother &re

Age 27,I am being forced by my parents to give my entire salary to them.I earn around 1.5 Lac/month.My parents have been abuse towards me since I was a kid.I faced a lot of mental & physical abuse(lot of beatings) from them esp my mother for studies & also to be her obedient little kid & also she always said that you will have to give me full salary after you get the job.This lasted till 23. Somehow by hooks & hardwork, I got a job & now earn pretty good money. But this corona came & went back to home due to uncertainty, now things have gotten worse between me & my family. My mother being the manipulative one has entire family on her side. I won't give my hard earned money at any cost , so I want to know how to break all legal ties with them(parents & brother & my parents family too).And I mean all , I don't want to see their faces again & if they try to interfere in my life again then I should be able to call police & file a case against them.
