When Do an Attorney-in-Fact's Powers Terminate?

An attorney-in-fact under a durable power of attorney loses power to act on behalf of the principal when the attorney-in-fact has actual knowledge of the death of the person who appointed him attorney-in-fact.  RCW 11.94.020.  Other events, such as revocation of the durable power of attorney, appointment of a guardian by a court, or removal of the attorney-in-fact by a court also terminate the powers of an attorney-in-fact.
