Disclaimers: what you should do when you receive a disclaimer

Before you apply the IHT provisions dealing with disclaimer, you need to check that what you are concerned with really is a disclaimer. Experience shows that the effect of a disclaimer is frequently misunderstood.  For example, an interest under a will may be disclaimed without regard to the consequences of the partial intestacy thereby produced.  Alternatively, the person disclaiming may purport to go on to redirect all or part of the property in which their original interest has been extinguished; such an attempt is totally inconsistent with the legal concept of disclaimer. 

Considerable care is therefore necessary in the consideration of any document embodying a disclaimer that purports to be other than a simple comprehensive relinquishment of the beneficial interest of the person making it.

Where this is the case and the disclaimer meets the other conditions in IHTA84/S142, and you are authorised to do so, you may accept that the disclaimer falls within IHTA84/S142 following the appropriate instruction at IHTM35151.
