There may be problems, brought on by passing time and human nature, with naming two or more people to share the job. In the critical time during which they would be overseeing your wishes and directing your care, they might disagree, rendering them ineffective as lobbyists on your behalf. Feuding agents could even end up settling their dispute in court, further delaying and confusing your care.

If you fear that those close to you may feel hurt if you name someone else to represent you, take some time to talk with them to explain your choice. Or, if there are several people you'd feel comfortable naming, you might even let them decide among themselves who the agent will be. If you approve of their choice, you can accept it -- and name the others as alternate agents in case your first choice can't serve.

It's a good idea to name at least one alternate agent, but you should be as thoughtful about naming your alternates as you are about picking your first choice: Be sure to name people who will represent you well if the need arises.

If you don't name an agent, you should still complete a living will (health care declaration), stating any wishes for medical care about which you feel strongly. Even without an agent, medical personnel are required to follow your written wishes for health care -- or to find someone who will care for you in the way you have directed if they cannot.

If you do not name a health care agent, also be certain to discuss your wishes for medical care with a doctor or a hospital representative who is likely to be involved in providing that care.
