If children from second wedlock become ineligible to receive pension, such share of the family pension would not get lapsed but would be payable to legally wedded wife or her children as the case may be in full i.e. 100%
On the death of a legally wedded wife who is not survived by any eligible child, share of the family pension would not lapse but would be payable to children from second wedlock in full i.e. 100%.
