• How to disown parents

I am 26 yr old guy living and working in Bangalore. I am born and bred in Chandigarh. 
I have an elder sister whos married and lives with her spouse and in laws in Chandigarh close to my parents house in the same neighborhood.

My parents struggled through immeasurable economic hardships to raise my sister and me and get us educated and qualified. The economic problems have been there since I remember it. 

My father is a partially visually disabled and mother is not very educated.
They've been blacklisted by all the banks because they've defaulted a lot of times due to money problems.

But somehow they built a small business which my mother runs, a house and a piece of land. My sister did her MBA and works in an MNC and is married in a rich family of the same caste.

I finished my engineering and started a job 4 yrs back and did exceptionally good and got promoted multiple times.

Since the day I graduated I wanted to pursue my life my way.
I wanted to get further qualified and struggle in life. For this I wanted to go for further studies.
But my mother never supported me. (Father is partially visually disabled and has no say in matters)

For stopping me from studying further and being a free bird she requested me for a huge sum of money which I had to borrow as personal loan from 2 banks which she agreed to help me repay but never did. I saw extremely bad days while repaying them back and plans of studying went down in drain.

Post that I started focusing on job, got salary hike, filed 2 patents and won partial scholarship for a US university.
At this point I asked my mother to help me financially or with mortgage on the house which she refused.

According to her she's raised me to serve her and it's too risky for them to gamble with the property like this etc.
During these 4 yrs I never talked to my mother, but I tried solving issues by visiting home twice a yr. She never visited back.  Recently she came to Bangalore and laid down her plan for my life which I was asked to follow. 

Studies were out of plan and marriage as per her choice and surrendering all my savings for studies to her etc were also asked.

At this point I have decided to not be related to her and legally split myself away. 
They've raised me and sister by sacrificing everything in their life but spoiling my life to win back their lost comforts is also wrong. 

Can u help me with the legal way of splitting away.

I want to nominate myself as not a share holder or successor for their properties and assets and not liable to pay them anything either.

Please help me understand the law.
