A living will and a medical power of attorney are types of advance directives. These forms describe the kinds of medical care you want to receive if you're badly hurt or have a serious illness that keeps you from saying what you want. A medical power of attorney lets you name a person to be your health care agent. He or she can make decisions for you if you can't speak for yourself.
Many states have a unique form (for example, they may ask you to address specific issues). Or you might use a universal form that has been approved by many states. This kind of form can sometimes be completed and stored online. Your electronic copy will then be available wherever you have a connection to the Internet. Doctors typically respect your wishes even if you have a form from a different state.
