Updated August 3, 2026. Quick answer: Wisconsin calls this instrument declaration to health care professionals (living will), power of attorney for health care. To execute it you need 2 witnesses — and the state requires Witnesses only — no notary path stated. Getting that conjunction wrong is the most common way a directive fails when it is needed.
The execution box
| What the state calls it | declaration to health care professionals (living will), power of attorney for health care |
|---|---|
| Witnesses required | 2 |
| Witnesses or notary? | Witnesses only — no notary path stated |
| Who may NOT witness | Persons related to the declarant/principal by blood, marriage, or adoption (or domestic partner under ch. 770); persons with knowledge they are entitled to or have a claim on a portion of the estate; persons directly financially responsible for the health care; a health care provider serving the principal at the time of execution or an employee of that provider (excluding chaplains/social workers); and, for the power of attorney, the principal’s health care agent. Witnesses must be at least 18 years of age. |
| If you are in a care facility | No special rule found in the text we read |
| Authority | Wis. Stat. §154.03 (declaration to health care professionals); Wis. Stat. §155.10 (power of attorney for health care) |
What the statute says
Signed in the presence of 2 witnesses who meet the requirements of sub. (2).
— Wis. Stat. §154.03 (declaration to health care professionals); Wis. Stat. §155.10 (power of attorney for health care)
The form
The statute refers to a form, but we could not retrieve an official copy to link. Ask your state health department or check the statute itself — many states publish one free. We are not linking a commercial seller in its place.
Why the witness rules matter more than the wording
People spend their effort on what the directive says and almost none on how it is signed. A directive that expresses your wishes perfectly but was witnessed by someone the statute disqualifies may not be honoured. The disqualification lists exist because the people most likely to be in the room — family, the treating doctor, facility staff — are the people with an interest in the outcome.
Two practical consequences. Ask who is signing before the appointment, not during it. And if you are already in a hospital or care facility, check the facility rule row above — several states add a requirement that applies only to patients and residents, and it is the one nobody mentions.
This is the medical instrument, not the financial one
A financial power of attorney is a different document with different execution rules. Having one does not give anyone authority over your medical care, and having this one gives nobody authority over your money. Most people need both, and they are executed separately.
What could not be verified
Remote/videoconference execution under both chapters requires supervision by a Wisconsin-licensed attorney, who may serve as one of the two witnesses — this is a special remote-execution rule, not a notary requirement, and does not change the base in-person rule of 2 witnesses only.

General information drawn from state statutes and official state materials, not legal or medical advice. Advance-directive law is STATE law and the execution requirements differ in ways that decide whether a document works: some states require witnesses AND a notary, some accept either, and the list of people who may not witness varies. A directive executed the wrong way may not be honoured when it matters. Many states publish a free official form – you should not have to buy one.
