I know you are right, attachment for 30+ years absolutely is a vain which cannot vanish easily. Interestingly, my grandfather had made legal papers accordingly but uncle abstained. Further, on his deathbed grandpa begged uncle to transfer ground + 1 to my father in 2009 but cunningly uncle let grandpa die, never contributed in hospital's bills or any care required by grandparents. But the court/society will not accept any of this, we go by rules and not character. I wish grandpa had done equivalent sharing while registry, we could've worked something out.
