IHTM15053 - The extent of the share (Scotland): which law to apply to joint investments owned by someone domiciled in Scotland
Scottish law applies to shares of a company registered in Scotland. If the IHT400 (IHTM10021) or other account does not indicate whether a company is Scottish or not, you should be able to find this information on the Internet. If the taxpayer is of Scots domicile (IHTM13000) a joint holding in Government Stock may be regarded as subject to Scots law (Cunningham’s Trs v Cunningham [1924] SLT 502).
