(2)  In the case of a disposition made for public or charitable purposes, the words “5 years” in subsection (1) shall be read as “12 months”.

(3)  In the case of settled property, where the interest of any person under the settlement fails or determines by reason of his death before it becomes an interest in possession, and subsequent limitations under the settlement continue to subsist, the property shall not be deemed to pass on his death.

(4)  Where by a disposition of any property an interest is conferred on any person other than the disponer for the life of that person or determinable on his death, and that person enters into possession of the interest and thenceforward retains possession thereof to the entire exclusion of the disponer or of any benefit to him by contract or otherwise, and the only benefit which the disponer retains in the property is subject to such life or determinable interest, and no other interest is created by that disposition, then, on the death of that person, the property shall not be deemed to pass by reason only of its reverter to the disponer in his lifetime.

(5)  Where, by a disposition of any property, the interest mentioned in subsection (4) is conferred on 2 or more persons, either severally or jointly, or in succession, that subsection shall apply in like manner as where the interest is conferred on one person.

(6)  Subsections (4) and (5) shall not apply where such person or persons taking such life or determinable interest had at any time prior to the disposition been himself or themselves competent to dispose of such property.
