Section 113(iv) in The Indian Succession Act, 1925
(iv)A bequeaths a sum of money to B for life, and directs that upon the death of B the fund shall be settled upon his daughters, so that the portion of each daughter may belong to herself for life, and may be divided among her children after death. B has no daughter living at the time of the testator’s death. In this case the only bequest to the daughters of B is contained in the direction to settle the fund, and this direction amounts to a bequest to persons not yet born, of a life-interest in the fund, that is to say, of something which is less than the whole interest that remains to the testator in the thing bequeathed. The direction to settle the fund upon the daughters of B is void.
