This section of the manual tells you about applications for
clearance.
It provides
With effect from April 2007, you should treat the non-statutory assurance ( IHTM40151) given by SL124A & SL124B in all respects as if the taxpayer had applied for and you had issued formal clearance on form IHT30. You should therefore consider the instructions in this section before you issue a non-statutory assurance. Particularly
Once you have issued a non-statutory assurance you should treat any further developments on the case in accordance with the instructions in this section and on the basis that clearance has been given. This paragraph does not apply to Estate Duty cases.
