Effective - 28 Aug 1997   404.723. Delegation of powers, successor attorneys in fact — court's powers, appointments for incapacitated or disabled persons. — 1. An attorney in fact or successor from time to time may revocably delegate any or all of the powers granted in a durable power of attorney to one or more qualified persons, subject to any directions or limitations of the principal expressed in the power of attorney, but the attorney in fact making the delegation shall remain responsible to the principal for the exercise or nonexercise of the powers delegated.  2. The principal in a durable power of attorney may revocably name one or more qualified persons as successor attorneys in fact to exercise the authority granted in the power of attorney in the order named in the event a prior named attorney in fact resigns, dies, becomes disabled or incapacitated, is not qualified to act or refuses to act; and the principal in a durable power of attorney may revocably grant a power to another person, designated by name, by office, or by function, including the initial and any successor attorney in fact, whereby there may be revocably named at any time one or more successor attorneys in fact.  3. A delegated or successor attorney in fact need not indicate his or her capacity as a delegated or successor attorney in fact.  4. If a wholly or partially incapacitated or wholly or partially disabled person has provided for personal care or property management in an unrevoked durable power of attorney which the court finds is reasonably adequate to provide guidance to the attorney in fact for the conduct of the principal's personal or business affairs, and there is no attorney in fact or successor designated in the durable power of attorney who is willing, able and available to act, the court in lieu of appointing a full or limited guardian or a full or a limited conservator may appoint any adult person or financial institution as successor attorney in fact to act pursuant to the incapacitated or disabled principal's durable power of attorney, with or without bond and with or without court supervision, upon such terms and conditions as the court may require. In lieu of or in addition to appointing a successor attorney in fact or a limited or full conservator for management of a disabled person's estate the court may appoint any adult person or financial institution to act as personal custodian of the disabled person's estate pursuant to section 404.510. None of the actions described in this subsection shall be taken by the court until after hearing upon reasonable notice to all persons identified in a verified statement supplied by the petitioner who is requesting such action identifying the immediate relatives of the principal and any other persons known to the petitioner to be interested in the welfare of the principal; except that in the event of an emergency as determined by the court, the court may, without notice, enter such temporary order as seems proper to the court, but no such temporary order shall be effective for more than thirty days unless extended by the court after hearing on reasonable notice to the persons identified as herein provided. ­­-------- (L. 1989 H.B. 145 § 11, A.L. 1997 S.B. 265)
