A Washington medical power of attorney form is used to establish the life-extending healthcare procedures in addition to allowing someone to select an agent to make decisions on their behalf. The person creating the form, the “principal,” will need to choose an agent to manage all decisions made when the principal is incapacitated. Most people will choose a spouse, relative, or close friend as their agent. In Washington, residents are restricted from choosing an agent involved in their healthcare unless they are a direct relative. In any case, the agent must be someone who has a firm understanding of the principal’s values as related to healthcare.
