Will speaks from death
17.—(1) Every will is to be construed, with reference to the property referred to in it, to speak and take effect as if it had been executed immediately before the death of the testator, unless a contrary intention appears from the will.
(2) No conveyance or other act, made or done subsequently to the execution of a will, of or relating to any property referred to in the will, prevents the operation of the will with respect to that property to the extent that the testator has power to dispose of that property.
(3) The reference in paragraph (2) to an act does not include an act which revokes the will.
