In a recent judgement, the Andhra Pradesh High Court held that in cases involving ancestral property, each coparcener or co-sharer (like sons and daughters) holds an independent and vested interest in that property. So, if a father signed a relinquishment deed favouring his son, it would only apply to the extent of the father's own undivided share and would not affect the rights of the other co-sharers, such as the daughters.
For those unfamiliar, a relinquishment deed is signed when someone wants to give away/surrender (relinquish) their rights to something.
