Foreign property: valuation of assets: fall in value relief

Fall in value relief (IHTM14621) under IHTA84/S131 also applies to foreign shares. The procedure is the same as that for UK shares (IHTM14621), but the exchange rate at the date of the relevant valuation (IHTM14626) must be used when valuing the transfer at death or sale.

To find the correct exchange rate, use one of the many currency conversion websites available on the internet.
