I act for a client who has recently reluctantly settled a dispute concerning the validity of a will by which he was appointed executor of an estate. It has been agreed that the will was invalid and that an earlier will shall be proved instead. The client is the Attorney under an LPA for P&F for a relative who will benefit under the earlier will but who would not have benefited from the other. The client is a beneficiary in both wills but under the earlier will he will receive much less. The relative, who lacks capacity, is being required to consent in writing to the proving of the earlier will. The consent is to be provided to the Court in the will validity proceedings. My question concerns conflict of interest and the power of the client as Attorney. Firstly, does my client have power to consent on behalf of their relative/donor (there are no limitations in the LPA) and secondly, is there a conflict of interest in them doing so?
