Muslim law

if you are sunni muslims then you are governed by hanafi law and E and F have share over the property being a son of D ,being a son of D you both are entitled as 1/3rd share over that land but as said b also dies unmarried so as per muslim law share of B will also divide in his two brothers C and D then you will get 1/2 share in that land being a son of D but it is in that case when B is died before C and if B is die after C then then share of B will went to D and if D is died also then to his sons it means in this case E and F is entitled for 2/3rd share in that property and C was in 1/3rd share so he cant sell beyond his share i.e. 1/3rd share in that land.you can claim your share and you only have to show your succession certificate , documents of that land and sale deed copy of that LAND TO X .feel free to call if you left any query.
