law: Hindu Succession Act, 1956
  6. Devolution of interest of coparcenary property
  When a male Hindu dies after the commencement of this Act,
  
  having at the time of his death an interest in a Mitakshara coparcenary
  
  property, his interest in the property shall devolve by survivorship upon the
  
  surviving members of the coparcenary and not in accordance with this Act:
  PROVIDED that, if the deceased had left him surviving a
  
  female relative specified in class I of the Schedule or a male relative
  
  specified in that class who claims through such female relative, the interest
  
  of the deceased in the Mitakshara coparcenary property shall devolve by
  
  testamentary or intestate succession, as the case may be, under this Act and
  
  not by survivorship.
  Explanation I: For the purposes of this section, the interest
  
  of a Hindu Mitakshara coparcener shall be deemed to be the share in the
  
  property that would have been allotted to him if a partition of the property
  
  had taken place immediately before his death, irrespective of whether he was
  
  entitled to claim partition or not.
  Explanation 2: Nothing contained in the proviso to this
  
  section shall be construed as enabling a person who has separated himself from
  
  the coparcenary before the death of the deceased or any of his heirs to claim
  
  on intestacy a share in the interest referred to therein.
