Healthcare Directive in Illinois (2026)
An advance healthcare directive in Illinois requires 2 witnesses and does not require notarization. You must be at least 18 years old and of sound mind to sign one. The directive names a healthcare agent to speak for you and records the treatment you do and do not want. Illinois restricts who may witness it: cannot be the agent or healthcare provider. Do-not-resuscitate instructions use a separate Illinois form.
Nobody wants to think about this stuff. But Illinois has rules, and your family needs to know your wishes.

An Advance Healthcare Directive in Illinois is your way of telling doctors what to do when you can’t tell them yourself. It’s also how you pick someone to make medical decisions for you, because “I dunno, ask my mom” isn’t a viable healthcare strategy when you’re unconscious.
Requirements
Illinois requires 2 witnesses for a valid healthcare directive. You need to be at least 18 and mentally competent. Witness restrictions: Cannot be the agent or healthcare provider.
What it covers
Your healthcare directive in Illinois addresses the big uncomfortable questions: Do you want life-sustaining treatment? What about artificial nutrition? Pain management preferences? Organ donation? These are conversations nobody wants to have, which is exactly why you need to have them now, in writing, before someone else has to guess.
Important: In Illinois, a Do Not Resuscitate (DNR) order is a separate document from your healthcare directive. You’ll need to talk to your doctor about that one separately.
Choosing your healthcare agent
Pick someone who can handle pressure, knows your values, and won’t crumble when a doctor asks them hard questions at 3 AM. This person should know you well enough to make decisions you’d make for yourself, not the decisions they’d want for you.
Illinois law
Under 755 ILCS 5/4-3, your healthcare directive is legally binding in Illinois. Healthcare providers who refuse to follow it must transfer your care to someone who will. Your agent has the legal authority to access your medical records, talk to your doctors, and make treatment decisions.
Don’t wait
Here’s the thing about medical emergencies: they don’t send a calendar invite. One car accident, one stroke, one bad fall, and suddenly your family is making gut-wrenching decisions with zero guidance. A healthcare directive takes 15 minutes to fill out. That’s less time than you spent choosing what to watch on Netflix last night.
