31Exemption from estate duty of maintenance funds given to National Trust
(1)Any exemption from estate duty conferred by section thirty-one of the Finance Act, 1937, in relation to an estate or interest in land given, devised or bequeathed by any person to the National Trust shall, in the case of duty leviable on or with reference to a death occurring after the commencement of this Part of this Act, be granted also, and to the like extent, to any other property given, devised or bequeathed by him with that estate or interest as a source of income for the upkeep of the land.
(2)Property shall not be deemed for the purposes of this section to be given, devised or bequeathed with an estate or interest in land if either is subject to an interest or power of appointment created by the gift, devise or bequest to which the other is not subject:
Provided that for the purposes of this subsection any trust to apply income of the property for the upkeep of the land or in meeting liabilities or expenses accruing in respect of the land or the property (including a trust to accumulate income for any such purpose) shall be treated as creating the like interests in the property as may from time to time subsist in the land.
(3)Where property given, devised or bequeathed with an estate or interest in land is in the opinion of the Commissioners more than enough to provide (with a reasonable margin) for the upkeep of the land out of the income of the property, so much only as is in their opinion enough for that purpose shall be deemed to be given, devised or bequeathed as mentioned in subsection (1) of this section.
(4)In this section the expression " National Trust" means the National Trust for Places of Historic Interest or Natural Beauty or, in relation to Scotland, the National Trust for Scotland for Places of Historic Interest or Natural Beauty.
