Can someone who is acting as power of attorney for someone refuse to allow the person they are acting for to change their will on cost grounds, and can they be removed if it can be shown they are acting in their own interest?
When someone has made a Power of Attorney, they are still able to make their own decisions whilst they have the mental capacity to do so. Accordingly, provided that the person in question still has the mental capacity to make a Will then no-one including the Attorney can stop them from doing so. Likewise, if the person who made the Power of Attorney wishes to remove them as an Attorney, they are free to do so provided that they have the required mental capacity. I would recommend that professional help is sought when making a Will and removing an Attorney to ensure that the documents are effective and legally binding.
