In general law, a variation takes effect from the date of the
instrument and if it gave rise to a loss to someone's estate, there
will be a transfer of value. But provided the instrument satisfies
the conditions of IHTA84/S142, it will be treated for inheritance
tax purposes as if the redirection of property that formed part of
the deceased's estate (
IHTM04029) had been made by the
deceased. Where this applies, the redirection of property is not a
transfer of value, IHTA84/S17 (a).
In our view the word 'disposition' as used in IHTA84/S142 (1)
refers
so that the focus is on the post-death beneficial interest.
Accordingly the IoV must purport to change the destination of
property in the estate from that prescribed by the disposition
(however effected) which originally applied on the death to the
property.
