A commercial plot of size 30*60 was leased to my maternal grandfather, for 3 renewable terms of 33 years each, by the state of UP in the year 1956. The first lease term of 33 years ended in the year 1989. Thereafter it was never tried to get renewed (by both the parties). The plot was/is used for commercial as well as residential purpose.
My maternal grandfather passed away in the year 2010. He had 6 children (4 daughter and 2 sons, eldest being my mother). All of them are married and have adult children.
Now my maternal grandmother wishes to transfer the said property into my name. Also none of the family members have any sorts of doubts or issues in the said transfer. What is the best way to get it done? Kindly suggest a way which is least expensive and has maximum legal value. Also the deed or agreement must be irrevocable.
