HI
a) Under muslim law, Males and females have equal rights of inheritance. Upon the death of a Muslim, if his heirs include also the females then, male and female heirs inherit the properties simultaneously. Males have no preferential right of inheritance over the females, but normally the share of a male is double the share of a female.
In other words, although there is no difference between male and female heir in so far as their respective rights of inheritance is concerned but generally the quantum of property inherited by a female heir is half of the property given to a male of equal status (degree).
b) The principle that normally the share of a male is double the share of a female has some justification. Under Muslim law, while a female heir gets (or hopes to get in future) an additional money or property as her Mehr and maintenance from her husband, her male counterpart gets none of the two benefits. Moreover, the male heir is primarily liable for the maintenance of his children whereas, the female heir may have this liability only in an extraordinary case.
c) In india under muslim law there is no recognition of doctrine of representation.
- That is to say in your case, Children of M, A and N will not get any share of the property.
Rationale : Under muslim law, there can be no claim through a deceased person in whom no right could have been vested by any possibility. But, this stand of has been criticized by several mullah's and it is true that non-recognition of principles of representation under the Muslim law of inheritance, seems to be unreasonable. It is unreasonable that a son, whose father is dead, is unable to inherit the properties of his grandfather together with his uncle.
d) However under sunni law you can divide the property in to 6 parts . then you can adjust the cash payment made to the daughters.
After adjusting the cash payment to daughters, you can balance the properties in to 6 parts so that M, R, A, K , D and N get their respective shares without any ill bearing or ill will.
Hope this helps.
