Property of Grandfathers

First try to get the WILL copy  and ascertain the validity. If it is genuine then you can consult local lawyer and file a case against your uncles.

Hello,

If you are claiming a share in property under will then you should have a copy of the will. Appoint an advocate to trace out the will from the sub registrar's office if it is registered. 

 Firstly obtain the copy of your grandfather's will and ascertain whether your father has been given any share or not if  unable to obtain copy of your grand father's will then your father has to file suit for partition of your grandfather's property.
