My paternal grandfather has six siblings, but according to the will written by my great grand father, the property (house) should be equally portioned to my grandfather and one other sibling ONLY. My grandfather died in 2010. The sibling who is still alive and my grandmother sold this particular house in 2014, without the consent of my mother or myself. I am her first son's only daughter, and was a major at the time of selling.
Since the half portion of property rightfully belongs to me as much as the rest of the family, which includes my grandmother, two sons (my father and my uncle), myself, and my uncle's two children (both are minor); was my consent at least was necessary at the time of selling? Since that has not happened, how is it that I can seek justice?
