(1)Where property which ceases to be comprised in one settlement becomes comprised in another then, unless in the meantime any person becomes beneficially entitled to the property (and not merely to an interest in possession in the property), it shall for the purposes of this Chapter be treated as remaining comprised in the first settlement.
(2)Subsection (1) above applies only if the date on which property ceases to be comprised in a settlement falls after 9th December 1981; but where property ceased to be comprised in one settlement before 10th December 1981 and after 26th March 1974 and, by the same disposition, became comprised in another settlement, it shall for the purposes of this Chapter be treated as remaining comprised in the first settlement.
