My parents got married in a temple in 1972, although my dad was married earlier to another woman and had 2 kids. In the same year, my grandparents and my father wrote will that gave the property to his first wife and her children. My father and his wife passed away recently. Now, the court has named all four children as the legal heirs to the property, excluding my mother (his second wife). So do we have the rights to the ancestral home based on this?
