Words used in Wyoming
In Wyoming you name an agent for money and property in a power of attorney, and an agent for medical decisions in a power of attorney for health care. Your written treatment wishes are called individual instructions; both are advance health care directives. If an adult cannot decide and has no documents, family members can act as surrogate, and a district court can appoint a guardian and a conservator.
An agent (also called an attorney-in-fact) is the person you choose to act for you. You are the principal.

- How to revoke
You can revoke a power of attorney or an agent's authority. The Act does not set a required method; the Wyoming Judicial Branch self-help page says to revoke it in writing. Signing a new power of attorney does not revoke an earlier one unless the new one says so.
- Telling others
Tell the agent and every bank or business that has a copy. An agent or other person who acts in good faith without actual knowledge that the power of attorney or the agent's authority has ended is protected.
Law: Wyo. Stat. § 3-9-110
Banks, other states and real estate
- Banks and other businesses
A person asked to accept a notarized (acknowledged) power of attorney must accept it, or within 7 business days ask for an agent's certification or an English translation, and then accept it within 5 business days after receiving it, unless a legal reason to refuse applies (for example, a good-faith belief it is invalid, or a report to a protective agency of suspected abuse or exploitation). A person may not demand a different form. Wrongful refusal can lead to a court order and liability for reasonable attorney's fees and costs. A photocopy or electronically sent copy has the same effect as the original.

Law: Wyo. Stat. § 35-22-403(d), (e)
- Decisions an agent cannot make

If you have no directive
- Who decides without a directive
If there is no valid directive and no available agent or guardian, a surrogate may decide once your primary physician or primary health care provider determines you lack capacity. The law lists family members in a suggested descending order of priority. If members of a class disagree, the provider follows the majority of those who have spoken. The provider may ask the surrogate for a written declaration under penalty of perjury supporting their authority. You can disqualify anyone in writing or by telling your provider.
- A person you named as surrogate by telling your primary health care provider
- Spouse (unless legally separated)
- Adult child
- Parent
- Grandparent
- Adult brother or sister
- Adult grandchild
