A grandfather in Gurgaon has made a registered will bequeathing all ancestral agricultural land to his son (the mother's brother), excluding his daughter (the mother). The key legal question is whether this is permissible. Generally, daughters have equal rights to ancestral property as sons. The grandfather can only will away his own share, not the entire ancestral property. The mother should consult a local advocate, file a partition suit to claim her share, and seek an injunction to prevent the brother from selling the property until the case is decided.
