(1) If a directive authorizes the appointment of an agent, the provisions of chapter 11.94 RCW and RCW 7.70.065 shall apply unless otherwise stated in this chapter.

     (2) The principal who appoints an agent must notify the agent in writing of the appointment.

     (3) An agent must act in good faith.

     (4) An agent may make decisions on behalf of the principal. Unless the principal has revoked the directive, the decisions must be consistent with the instructions and preferences the principal has expressed in the directive, or if not expressed, as otherwise known to the agent. If the principal's instructions or preferences are not known, the agent shall make a decision he or she determines is in the best interest of the principal.

     (5) Except to the extent the right is limited by the appointment or any federal or state law, the agent has the same right as the principal to receive, review, and authorize the use and disclosure of the principal's health care information when the agent is acting on behalf of the principal and to the extent required for the agent to carry out his or her duties. This subsection shall be construed to be consistent with chapters 70.02, 70.24, 70.96A, 71.05, and 71.34 RCW, and with federal law regarding health care information.

     (6) Unless otherwise provided in the appointment and agreed to in writing by the agent, the agent is not, as a result of acting in the capacity of agent, personally liable for the cost of treatment provided to the principal.

     (7) An agent may resign or withdraw at any time by giving written notice to the principal. The agent must also give written notice to any health care provider, professional person, or health care facility providing treatment to the principal. The resignation or withdrawal is effective upon receipt unless otherwise specified in the resignation or withdrawal.

     (8) If the directive gives the agent authority to act while the principal has capacity, the decisions of the principal supersede those of the agent at any time the principal has capacity.

     (9) Unless otherwise provided in the durable power of attorney, the principal may revoke the agent's appointment as provided under other state law.
