Sir/Madam,
My uncles along with my father entered a family agreement for partition of the ancestral property after the death of my grandfather in 1985. They have two sisters of whom one married in 1955 and the other in 1962. While making the family agreement in the year 2000 with the consent of my grandmother(paternal), they did not get the signatures of their sisters presuming that they had no rights as per HINDU SUCCESSION ACT 1956 (amendment 2005 did not arise).
Please clarify whether the family agreement is valid or does it require any ratification by their sisters now.
