19. Vested interest .—Where, on a transfer of property, an interest therein is created in favour of a person without specifying the time when it is to take effect, or in terms specifying that it is to take effect forthwith or on the happening of an event which must happen, su ch interest is vested, unless a contrary intention appears from the terms of the transfer. A vested interest is not defeated by the death of the transferee before he obtains possession.
Explanation. —An intention that an interest shall not be vested is not to be inferred merely -from a provision whereby the enjoyment thereof is postponed, or whereby a prior interest in the same property is given or reserved to some other person, or whereby income arising from the property is directed to be accumulated until t he time of enjoyment arrives, or from a provision that if a particular event shall happen the interest shall pass to another person.
