These are in a standard form under which you can appoint your chosen attorney(s) to act for you in the event of incapacity for any reason. It is very important that anyone with assets has one in place. In the absence of a Lasting Power of Attorney (or an old-style Enduring Power of Attorney - these remain valid), the Court of Protection would have to become involved in the administration of your affairs. A Lasting Power of Attorney can be flexible, for example, appointing your spouse, but with another attorney appointed to act if and only if your spouse is unable to do so. You may also want to consider an ordinary Power of Attorney, as an alternative to the complexities of a Lasting Power.
