Re K (Enduring Powers of Attorney), In re F: ChD 1988

The court allowed an appeal against the decision of the Master of the Court of Protection refusing registration to an enduring power of attorney on the ground that the donor, although capable of understanding the nature of the power, was herself incapable by reason of mental disorder of managing her property and affairs at the time that she executed the power. For a juristic act to be valid, the person performing it should have the mental capacity (with the assistance of such explanation as he may have been given) to understand the nature and effect of that particular act. In the context of litigation, the test to be applied is: ‘whether the party to legal proceedings is capable of understanding, with the assistance of such proper explanation from legal advisers and experts in other disciplines as the case may require, the issues on which his consent or decision is likely to be necessary in the course of those proceedings.’ There is no logical reason why a person who understands that something needs to be done, but who does not have the requisite understanding to do it for himself, should not confer on another the power to do what needs to be done.
Hoffmann J said: ‘there is no logical reason why, though unable to exercise her powers, [the donor] could not confer them upon someone else by an appropriate juristic act. The validity of that act depends on whether she understood its nature and effect and not on whether she would hypothetically have been able to perform all the acts which it authorised.’ and
‘I do not think that it would be sufficient if he realised only that it gave Cousin William power to look after his property. Mr Rawson [counsel instructed by the Official Solicitor] helpfully summarised the matters which the donor should have understood in order that he can be said to have understood the nature and effect of the power. First (if such be the terms of the power) that the attorney will be able to assume complete authority over the donor’s affairs. Secondly (if such be the terms of the power) that the attorney will in general be able to do anything with the donor’s property which he himself could have done. Thirdly, that the authority will continue if the donor should be or become mentally incapable. Fourthly, that if he should be or become mentally incapable, the power will be irrevocable without confirmation by the court. I do not wish to prescribe another form of words in competition with the explanatory notes prescribed by the Lord Chancellor, but I accept Mr Rawson’s summary as a statement of the matters which should ordinarily be explained to the donor (whatever the precise language which may be used) and which the evidence should show he has understood.’
