With an advance health care directive, you can designate someone to make healthcare decisions for you in the event that you become unable to do so for yourself. In addition, this legal document can contain your wishes concerning such matters as life-sustaining treatment and other health care issues and instructions concerning organ donation, disposition of remains and your funeral. (You can revoke the directive at any time, as long as you are still competent.
Otherwise, without a document indicating your wishes, if you become unable to make decisions or care for yourself, a court could appoint a court supervised conservator to manage your affairs and be responsible for your care. Conservatorships are generally more cumbersome, expensive and time-consuming than the appointment of attorneys-in-fact under powers of attorney.4
