This is a critically important question for families in Mumbai dealing with ancestral property disputes, and the clear legal answer is that a coparcener cannot validly gift away ancestral property, or even their own undivided share in it, without the consent of the other coparceners, except within very narrow and specifically recognised exceptions. Under Hindu law as codified and interpreted through the Hindu Succession Act, 1956, ancestral property is fundamentally different from self-acquired property precisely because no single coparcener holds absolute, unrestricted ownership over the whole — each coparcener holds only an undivided interest, making unilateral gifting of the entire property, or even a specific portion exceeding one's own share, legally impermissible.

The general rule, affirmed repeatedly by Indian courts including the Bombay High Court, is that a gift of ancestral property by a coparcener without the consent of other coparceners is void, not merely voidable, to the extent it exceeds the donor's own undivided share, since the very essence of coparcenary ownership prevents any single member from disposing of what belongs jointly to all coparceners without their agreement. This means other coparceners who discover such an unauthorised gift have strong grounds to challenge it and seek its cancellation to the extent it improperly encroaches on their rightful shares.

There are limited, narrow exceptions recognised under Hindu law where a coparcener, and in particular the karta or manager of a Hindu Undivided Family, can make gifts of ancestral property without requiring consent of all coparceners — these include gifts made for pious or religious purposes within reasonable limits, gifts to a daughter at the time of her marriage that are reasonable considering the family's status and the value of the property involved, and in certain circumstances, gifts made for the maintenance of family members in genuine need. Beyond these specifically recognised categories, however, courts apply the general rule strictly, and any broader gift purporting to transfer ancestral property without coparcener consent faces serious vulnerability to challenge.

Where such an unauthorised gift has occurred, affected coparceners can file a suit for declaration that the gift is void to the extent it exceeds the donor's rightful share, combined with a suit for partition to formally determine and secure their own rightful portion of the ancestral property, ensuring the improperly gifted excess is brought back into the partition calculation for fair distribution among all rightful coparceners.
