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.

Starting later (springing)

It is effective when signed unless it says it starts on a future date or event. You can name who decides that the event happened. If it starts on your incapacity and no one you named can decide, it starts when a physician or licensed psychologist, or an attorney, judge or appropriate government official, determines in writing that you are incapacitated.
