The powers available to HMRC to request information or documents from a third party (a Third Party Notice) where it is reasonably required by HMRC for checking the tax position of a taxpayer are generally well known. What is not so well known is the limited opportunities available to a third party who might wish to challenge the terms or scope of a Third Party Notice.

It is not uncommon for companies, often property related joint ventures or single purpose vehicles, to be incorporated abroad for tax reasons but carry on much of their business in Scotland or elsewhere in the U.K. This can result in difficulties when determining where to initiate insolvency proceedings.
