(1) In a power of attorney, a principal may nominate a conservator or guardian of the principal's estate or guardian of the principal's person for consideration by the court if protective proceedings for the principal's estate or person are begun after the principal executes the power of attorney.

(2) If, following execution of a durable power of attorney, a court of the principal's domicile appoints a conservator, guardian of the estate, or other fiduciary charged with the management of all the principal's property or all of his or her property except specified exclusions, the agent shall be accountable to the fiduciary as well as to the principal. The fiduciary shall have the same power to revoke or amend the power of attorney that the principal would have had if he or she were not disabled or incapacitated.
