In addition to planning for the financial aspect of your affairs during incapacity, you should establish a plan for your medical care. The law allows you to appoint someone you trust, for example, a family member or close friend, to make decisions on your behalf about medical treatment options if you lose the ability to decide for yourself. You can do this by using a durable power of attorney for health care where you designate the person to make such decisions. In addition to a power of attorney for health care, you should also have a living will. Living wills inform others of your preferred medical treatments, such as the use of extraordinary measures should you become permanently unconscious or terminally ill.
