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.

For lawyers dealing regularly with commercial secured lending, the requirement to register company fixed and floating charges has long been fraught with tension. It is a commercial necessity for charges over a company's assets to be registered in a publicly available register. Prospective creditors need to be able to establish how far the company's assets have been secured and are available to meet its commitments. Failure to register will result in the charge being invalid against any liquidator, administrator or creditor of the company if the company becomes insolvent.
