Rule 2.- The surviving sons and daughter and the mother of the intestate shall each take one share.
Rule 3.- The heirs in the branch of each pre-deceased son or each pre-deceased daughter of the intestate shall take between them one share.
Rule 4.- The distribution of the share referred to in Rule 3-
(i) among the heirs in the branch of the pre-deceased son shall be son made that his widow (or widows together) and the surviving sons and daughters get equal portions, and the branch of his pre-deceased sons gets the same portion.
(ii) among the heirs in the branch of the pre-deceased daughter shall be so made that the surviving sons and daughters get equal portions.
Likewise all the children of the deceased Hindu borne by the first wife or the second wife shall have equal right in his property by virtue of this section as well section 16 of the Hindu Marriage Act which gives legitimacy to the children born from marriage declared null and void or annulled by a decree of nullity ,read this provision too:- Legitimacy of children of void and voidable, marriages.- Where a decree of nullity is granted in respect of any marriage under section 11 or section 12, any child begotten or conceived before the decree is made who would have been the legitimate child of the parties to the marriage if it had been dissolved instead of having been declared null and void or annulled by a decree of nullity shall be deemed to be their legitimate child notwithstanding the decree of nullity :
Provided that nothing contained in this section shall be construed as conferring upon any child of a marriage which is declared null and void or annulled by a decree of nullity any rights in or to the property of any person other than the parents in any case where, but for the passing of this Act, such child would have been incapable of possessing or acquiring any such rights by reason of his not being the legitimate child of his parents.
