Who Makes Medical Decisions If You Can’t?
A Living Will and a Health Care Power of Attorney are two important tools that help guide medical decisions when you are unable to speak for yourself. While they serve different purposes, using them together can provide clarity, flexibility, and peace of mind for both you and your loved ones.
Planning for future medical decisions is difficult because no one can predict what their health will look like years from now. Still, having a plan in place can make an enormous difference when decisions need to be made quickly and under stress.
Illinois law recognizes several types of health care directives designed to make your wishes clear if you become unable to make medical decisions on your own. Two of the most common are a Living Will and a Power of Attorney for Health Care. While they sound similar, they work in different ways.
Let’s walk through how each one functions and why many people choose to have both.

What Is a Living Will?
A Living Will is a written statement that addresses whether you want death-delaying procedures withheld or withdrawn if you are diagnosed with a terminal condition.
In practical terms, it provides instructions to your physician about what types of treatment you do or do not want in very specific end-of-life situations. Because it is limited to the language written in the document, its scope is fairly narrow. It does not cover every medical scenario, and it does not appoint someone to make decisions on your behalf.
For that reason, a Living Will works best as a statement of values rather than a complete medical decision-making plan.
What Is a Power of Attorney for Health Care?
A Power of Attorney for Health Care allows you to appoint someone you trust to make medical decisions for you if you are unable to do so yourself.
This document offers much more flexibility. Instead of relying only on written instructions, you are choosing an agent who can respond to real-world situations as they arise. Most Health Care Powers of Attorney allow you to give direction about your preferences, such as whether you prioritize quality of life or length of life, and when your agent’s authority begins.
Your agent’s authority is broad and is meant to adapt to circumstances that cannot be fully anticipated ahead of time.
How the Two Documents Work Together
A Power of Attorney for Health Care generally provides broader authority, while a Living Will is more limited to the situations described in the document.
That said, they are often most effective when used together. A Living Will can clearly express your wishes in writing, while a Health Care Power of Attorney gives someone you trust the ability to apply those wishes thoughtfully when real decisions need to be made.
Together, they help ensure that your values guide your care, even when you cannot speak for yourself.
