Even if you are currently the picture of good health, you may suddenly become too ill to make healthcare decisions for yourself or become unconscious after an accident, needing someone to stand in your shoes to make those decisions for you. A medical power of attorney is a crucial part of your estate plan that enables you to name a trusted person to make healthcare decisions for you, if and when needed. It is essential for the person you name to have the information necessary to carry out your wishes for your medical care.
