Hindu Succession Act
Joint family property
Under the Mitakshara School, the joint family property devolves by survivorship.
When a male Hindu dies after the commencement of this Act having at the time of his death an interest in a Mitakshara coparcenery property, his interest in the property shall devolve by survivorship upon the surviving members of the coparcenery and not in accordance with this Act.
However if the Mitakshara dies leaving behind a female relative or male relative claiming through Class I, this undivided interest will not devolve by survivorship but by succession as provided under the Act.
