Land ownership if we are living here for more than 50 years.

Situation explanation:- Recently my dad passed away and things have become quite difficult for us I'm a 19 year old boy and want to know about the things I can do in this case .My dad and his 2 brothers who are partners in a petrol pump licence my dad operated the petrol pump for more than 50 years the land belonged to someone else let's consider him A and my dad had a lease to run the petrol pump as the lease was about to expire my dad met a man B. Now My dad introduced B to A and B was ready to buy the land and he bought a part of land where the petrol pump was running and in a part of that land we have our house and this land is not a general plot so I just wanted to know is there anything I can do about to get the land where my house is there The electricity bill is in my grandfather's name which collectively supplies electricity to the petrol pump and my home . So is there any was I can make the land officially in my mother's name as we're living here since 50 year's. Even a small contribution in order to help this matter would be highly appreciated. Thank You.
