Enduring power of attorney is an older term, for what is now known as lasting power of attorney.
A power of attorney which takes effect in the future. If a person is capable of dealing with their own affairs at present, they can sign an enduring power of attorney. It will only come into effect when they are no longer capable of looking after their own affairs.
It gives authority to the person appointed to act for the person who signed the power of attorney. (Enduring power of attorney (EPA) was replaced by lasting powers of attorney (LPA) on 1 October 2007. An EPA made before this date is still legal and can still be registered with the Office of the Public Guardian. After this date, you must make an LPA instead.)
