Alone senior citizen harresment and forcelly living in my home by daughter in law and son

I'm a 61 years senior citizen retired pensioner and living at Lucknow. My wife expired in 2007 after that I decided to sacrifice my balance life for my 1 daughter 25 yrs, 2 sons 24 and 18 yrs old. All was students in various courses.After that in 2010 my elder son got married and that time he was not doing any work and girl side knows this very well but that time I was a engineer in railways so financially no problem. After that in 2013 my only daughter got married and my younger son got job at Bangalore.In 2012 my daughter in law gave birth to male child, In short nearly all expenses from 2010 to 2017 bear by me including grandson Mundan function about and 3 younger sisters marriage of my daugher in law completed in 30th June 2017 and after marriage Once all these functions completed one day ie, Sept 03/2017 my daughter in law's So called Amma (not his real mother)was stayed in my home from last 3 days after attending my grandson birthday party was held on Sept 01/2017 and I was taking with my daughter in law about inefficiency of home cleaning and maintenance his so called Amma came from outer room of my home and starting abusive language with loudly unparliamentry language in front of daughter in law and my daughter in law not stop him to do so and when I told his Amma ( not his real mother) that I am your daughters father in law and how you can talk this abusive language in my home with me but not his Amma nor she stopped him.After that I told his Amma to immediately go out from my home.Then immediately my daughter in law reacted and asked me how you say my Amma to go out and start abusive language, when I asked when your Amma forcefully interfere in my home matter you got silent and when I reacted and only ask her to go out from my home you immediately reacted because you think I'm alone. All these argument time my son was not present but when his wife whatever told him he also started abusive language without knowing reason why I say get out to her Amma. My son a liquor addict and smoker and daughter in law also Pan Masala addict and doing no work to earn some bucks.I feels my life is in danger. They are living in my self earned home.I made my home on land which was not belongs to my late father but belongs to my Tauji (no land document present) who have no child. I have all expenses proof during home construction period.House Tax and water tax all paid by me and I have last 10 years receipts in my name. Another problem I was paying a land instalment in my wife's name and after my wife's death I changed name of wife with my son but land not registered yet. My question are for advise please: (1)Can I disown my son and daughter in law from my all property. (2) Can I take back my land which was name changed but not registered. All instalment was paid by me and maximum instalment receipt kept by me. (3)Can I take back my 2 lacs rupees which was given by me to my son for deposit in his bank account.
