provisions of hindu succession act are not applicable to agricultural lands in UP

2) Section 171 of the Zamindari Abolition and Land Reforms, 1950 Act clearly lays down that in case a male tenure holder dies then his son or his male descendants will come to inherit his rights in the holding of land. His own daughter and son’s daughter and the descendants of daughters have been excluded for this purpose

3)A married daughter has been completely excluded. If no male descendant is there, the rights of the deceased would come to be inherited even by his brothers or other male relatives but not by his own daughter. In categorical terms, the Act has preferred the brother of a deceased to a married daughter of the deceased for inheritance in tenure holding. Thus, even in a nuclear family where there is no male survivor, the married daughter cannot inherit the rights, rather her uncle has been found by our legislature in its wisdom, to be a suitable heir to inherit the tenure holding.
