My father inherited property from his mother (i.e., my grandmother). My father has 3 children (2 males & 1 female). First male unmarried. Second (myself) male married. Third is female, married. My father/ elder brother (who is unmarried) and my younger sister - all 3 of them have registered themselves a partition deed without my knowledge. What would be the legal strength if i go for a partition suit, claiming my right as a legal heir. Thanks. Please help advise me.
