Where a settlor or his spouse is beneficially entitled to an interest in possession in property immediately after it becomes comprised in the settlement, the property shall for the purposes of this Chapter be treated as not having become comprised in the settlement on that occasion ; but when the property or any part of it becomes held on trusts under which neither of those persons is beneficially entitled to an interest in possession, the property or part shall for those purposes be treated as becoming comprised in a separate settlement made by that one of them who ceased (or last ceased) to be beneficially entitled to an interest in possession in it.

References in subsection (1) above to the spouse of a settlor include references to the widow or widower of a settlor.

This section applies whether the occasion first referred to in subsection (1) above occurred before or after the passing of this Act, but not if it occurred before 27th March 1974.
