My friends father owned a house at village. He is no more. The father has a Mother (my friends grand mother), Wife (my friends mother) and one son(my friend). My friend is married and has now two kids (less than 5 years). Son(my friend) is repaying the loan amount for the house. The loan was taken in both's name while the house is taken in father's name.
Now, Who and all are eligible for the house ownership and should we change the property owner's name legally ?
