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.
