Equal Distribution of property

2 years ago

Dear Sir, This question is on behalf of my parents. They have a plot of three gunthas. They had constructed the ground floor where they are presently staying since 1990.
They have two sons and one daughter they had decided to give the first floor to the younger son and the second floor to the elder son.
So 5 years earlier, with everyone's consent the first and second floor was constructed.
A loan of 30 lacs was taken in a joint account of my younger brother and father's name.
The installments are still paid by my younger brother and some amount (10 lakhs was contributed by my parents and elder brother during the construction).
During the construction my elder brother invested in some other flat and hence did not contribute to much.
Presently my younger brother is staying on the first floor and second floor is vacant.
Now my parents question is if they would like to distribute the first and the second floor to both the brothers equally how can it be done without being unfair to both.
Ground floor construction 750 square feet
First and second floor both 1300 square feet each.
The question is not about the ground floor but about the first and the second floor how can it be distributed equally amongst both the brothers.
