35-22-403. Advance health care directives.
(a) An adult or emancipated minor may give an individual instruction. The instruction may be oral or written. The instruction may be limited to take effect only if a specified condition arises.
(b) An adult or emancipated minor may execute a power of attorney for health care, which may authorize the agent to make any health care decision the principal could have made while having capacity. The power must be in writing and signed by the principal or by another person in the principal's presence and at the principal's expressed direction. The power remains in effect notwithstanding the principal's later incapacity and may include individual instructions. Unless related to the principal by blood, marriage or adoption, an agent may not be an owner, operator or employee of a residential or community care facility at which the principal is receiving care. The durable power of attorney must be acknowledged before a notarial officer or must be signed by at least two (2) witnesses, each of whom witnessed either the signing of the instrument by the principal or the principal's acknowledgement of the signature or of the instrument, each witness making the following declaration in substance:
I declare under penalty of perjury under the laws of Wyoming that the person who signed or acknowledged this document is known to me to be the principal, and the principal signed or acknowledged this document in my presence.
(c) None of the following shall be used as a witness for a power of attorney for health care:
(i) A treating health care provider or employee of the provider;
(ii) The attorney-in-fact nominated in the writing;
(iii) The operator of a community care facility or employee of the operator or facility;
(iv) The operator of a residential care facility or employee of the operator or facility.
(d) Unless otherwise specified in a power of attorney for health care, the authority of an agent becomes effective only upon a determination that the principal lacks capacity, and ceases to be effective upon a determination that the principal has recovered capacity.
(e) Unless otherwise specified in a written advance health care directive, a determination that an individual lacks or has recovered capacity, or that another condition exists that affects an individual instruction or the authority of an agent, shall be made by the primary physician, but the treating primary health care provider may make the decision if the primary physician is unavailable.
(f) An agent shall make a health care decision in accordance with the principal's advance health care directive and other wishes to the extent known to the agent. Otherwise, the agent shall make the decision in accordance with the agent's determination of the principal's best interest. In determining the principal's best interest, the agent shall consider the principal's personal values to the extent known to the agent.
(g) A health care decision made by an agent for a principal is effective without judicial approval.
(h) A written advance health care directive may include the individual's nomination of a guardian of the person.
(j) An advance health care directive is valid for purposes of this act if it complied with the applicable law at the time of execution or communication.
