A power of attorney refers to a written instrument, executed by one person (the principal) that allows another person (the attorney in fact) to act on their behalf. If the principal dies the power of attorney is extinguished. If the attorney in fact dies the principal must execute a new power of attorney that names a new attorney in fact.
An enduring power of attorney remains valid even if the donor later becomes mentally incompetent. (Note: the donor must be competent at the time the power of attorney is made.) In either case, the power of attorney becomes invalid when the donor dies. A power of attorney cannot be used to bequeath property upon the death of the donor.
