A farmer died intestate. As a result of his children (adults) being entitled to half the residue, there would be IHT unless APR and BPR were successfully claimed.
If the children vary their entitlements in favour of their mother (deceased’s wife), so that spouse exemption could be claimed on the whole estate, would it still be necessary to submit an IHT400 with a copy of the variation to show the effect of the variation?
