This Practice Note, written by Adam Carvalho of Myerson, considers how a nil rate band (NRB) legacy in a Will may be interpreted by the court following the testator’s death. The construction of the Will clause will determine the amount of the NRB legacy, the assets comprised in it and the residuary estate. Due to ambiguous wording or an unclear intention as to whether or not assets which cause the estate to qualify for the NRB or residence NRB (RNRB) are included within the legacy, disputes often arise over the construction of these clauses. The Practice Note considers case law and the issues that the court will consider when interpreting the Will clause, as well as precedent wording for NRB legacies.
