When HMRC, by virtue of the charge afforded by IHTA84/S237 has an interest in
that interest can be asserted formally by the issue of a Stop
Notice to the Bank of England or the Company concerned.
A Stop Notice has the effect of compelling a Company
Registrar to give notice to HMRC of the taxpayer’s intention
to sell shares, thereby ensuring that HMRC is able to make a claim
on the proceeds.
