Kumar Doab (FIN) 22 September 2015
It is believed that you are Hindu and your Grandfather has not left any WILL and it was self acquired proeprty.
The property shall devolve equally upon two brothers.Your father's share shall devolve upon your mother,you and your brothers/sisters.
You can approach a lawyer specailizing in property/family/civil matters and try for amicable family settlement deed (registered) and if it is not possible file for partition suit.

if your grandfather had died intestate then both his sons will get equal share along with their mother in the property.file a partition suit to claim your rightful share if you are not able to arrive at a family settlement
