Basis for treating Self Acquired Property as Blended Property ?

Answer is simply no, self acquired property is absolute property of eldest brother and no one else has right to seek share in the same during his lifetime and even after his death if he dies making a Will in favour of anyone. His Cl 1 heir will be his widow and children and his brothers (Cl 2 heir) will not be getting share. As far the ancestral property each brother has share in it that can be partitioned amongst them. The self acquired property of any of the brother cannot be blended as ancestral property just for the reason it is agricultural in nature.
