Living Wills and Advance Directives in Wyoming

Under the Wyoming Health Care Decisions Act, an adult or emancipated minor may give individual health care instructions (the living-will part), orally or in writing, and the instruction may be limited to take effect only if a specified condition arises. The statute does not require a particular form or witnesses for an individual instruction. Instructions may also be included in a power of attorney for health care, which must then meet the power of attorney signing rules (notarized or signed before two qualified witnesses).

Wyoming uses a power of attorney for health care. It must be in writing, signed by the principal (or by another person in the principal's presence at his or her direction), and either acknowledged before a notarial officer or signed by two witnesses who each declare under penalty of perjury that the principal signed or acknowledged it in their presence. A treating health care provider or its employee, the named agent, or the operator or an employee of a community or residential care facility may not serve as a witness. Unless the document says otherwise, the agent's authority begins only when the principal is determined to lack capacity.
