A grandfather made a will in 2006 excluding one son (the father) from ancestral property. The father's subsequent legal challenge in 2010 was dismissed as 'not maintainable', and an appeal was also dismissed in 2012. The core question is whether this dismissed case will prevent the father from inheriting his share of the ancestral property upon the grandfather's death, especially if the judgment is considered incorrect. Experts generally agree that ancestral property rights are birthrights and cannot be entirely willed away; a grandfather can only bequeath his own share. Therefore, the father and his descendants may still have a claim to a share through a partition suit, despite the previous court rulings, especially if the property is indeed ancestral and the will was invalid regarding his birthright.
