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.
Unless a general power of attorney has a specific expiration date, or the principal revokes it in writing, or an event occurs that terminates it under the law, it should remain in effect until the death of the principal. A specific or limited power of attorney is limited by its terms.
