(a) Procedure.--

(1) Upon receipt of notice of a guardianship proceeding, a provider shall notify the court and the agent at the guardianship proceeding of the existence of a mental health advance directive.

(2) Upon receipt of a notice of guardianship proceeding, the agent shall inform the court of the contents of the mental health advance directive.

(b) Accountability of mental health care agent.--

(1) If a principal who has executed a mental health power of attorney is later adjudicated an incapacitated person, the mental health power of attorney shall remain in effect.

(2) The court shall give preference to allowing the agent to continue making mental health care decisions as provided in the mental health advance directive unless the principal specified that the guardian has the power to terminate, revoke or suspend the mental health power of attorney in the advance directive.

(3) If, after thorough examination, the court grants the powers contained in the mental health advance directive to the guardian, the guardian shall be bound by the same obligations as the agent would have been.

(c) Nomination of guardian of person.--In a mental health power of attorney, a principal may nominate the guardian of the person for the principal for consideration by the court if incapacity proceedings for the principal's person are thereafter commenced. If the court determines that the appointment of a guardian is necessary, the court shall appoint in accordance with the principal's most recent nomination except for good cause or disqualification.
