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.
This individual may also hold a power of attorney from the owner of the account (although that's not always necessary). An important note to remember is that an authorized signerâs privileges are only legitimate while the account owner is alive and if the account owner were to die, those privileges would cease.
