WILL is in son's name.can daughter claim her share in this property?

The said property is a residential property which was purchased by my father in 2003 in joint name with his wife( my mom)This property is his self acquired property. My father died in 2011.He had already made a Registered WILL in which he mentioned that all movable and immovable property will belong to his wife(i.e my mom) after his demise. So after the death of my father, my mother became the sole owner of the said property by virtue of WILL and his death Certificate.I got the Electricity meter and Water meter transferred in my mothers name.Also we are giving house Tax in my mother's name after my father's death. My mother also has made Registered WILL in 2005 in which she has stated that "if she expires before her husband(i.e my father) then all movable and immovable property will belong to her husband(i.e my father). and if her husband expires earlier than her than her than all movable and immovable property will belong to his son( i.e me)"
