My father passed away on 8 April 1981, and I was born on 14 February 1982. My mother married again after my father’s death. Can I legally claim a share of my grandparents’ property even though they oppose my claim?

Yes, you are legally entitled to a share of your grandparents’ property as their grandchild, even though your father passed away before your birth. You have a legal right to inherit property from your grandparents under the Indian Succession Act, 1925. Your mother’s remarriage does not affect your inheritance rights.
