Health-care providers normally try to respect your wishes, regardless of the form you use to indicate those wishes or the state in which you executed the form. Only if you spend significant amounts of time in more than one state do you seriously need to consider executing an advance directive for each state. In such cases, you should find out whether one document will meet the formal requirements of each state. As a practical matter, you may want to name different agents if one agent is not easily available in all locations. Generally speaking, your agent should be physically close to your place of care.
