Section 30 of the Hindu Succession Act, 1956 allows a Hindu to dispose of property "by will or other testamentary disposition", and its Explanation provides that the interest of a male Hindu in a Mitakshara coparcenary property "shall ... be deemed to be property capable of being disposed of by him" within the meaning of the section.

The section is about testamentary disposal only. Under classical Mitakshara law a coparcener could not make a gift of his undivided interest, and sale is governed by the general law of alienation, not by section 30.
