As per S.6(3) of the act, the Where a Hindu dies after the commencement of the Hindu Succession (Amendment) Act, 2005, his interest in the property of a Joint Hindu family governed by the Mitakshara law, shall devolve by testamentary or intestate succession, as the case may be, under this Act and not by survivorship, and the coparcenery property shall be deemed to have been divided as if a partition had taken place and,― (a) the daughter is allotted the same share as is allotted to a son.
(5) Nothing contained in this section shall apply to a partition, which has been effected before the 20th day of December, 2004
Thus, if a partition had taken place prior to 20/12/2004, then the daughters are not entitled to the share irrespective of their marital status.
