What are the succession rights of a married daughter ?

Sir, I am from a family of lawyers.My father died in 1993 intestate. I have two brothers and am the only daughter. My mother is also alive. My brother who was then a lawyer but (now in a Senior Judge in Delhi) manufactured a 'Will' bequething all movable and immovable property in Delhi and Himachal Pradesh between my younger brother, mother and himself. He also tricked me into signing papers on which I scribbled some signature not my real signatures. My father's self acquired property includes a house in Delhi, Mother & father's ancestral land in Himachal Pradesh. Can I demand share??
