To create a valid Wisconsin Power of Attorney for Health Care, you must be at least 18 and of sound mind, sign a written document that names a qualifying agent, and have two qualified adults witness your signature. The Wisconsin power of attorney for health care requirements are set out in Chapter 155 of the Wisconsin Statutes, and getting any of the execution details wrong can leave the document unenforceable at the moment you need it most.
Who Can Sign One
Any Wisconsin resident who is at least 18 years old and of sound mind can sign a Power of Attorney for Health Care.1Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.05 “Sound mind” means you understand what you’re signing, who you’re naming as your agent, and the kinds of decisions that person will be authorized to make.
No one can require you to sign a healthcare power of attorney as a condition of receiving medical care or being admitted to a facility, and not having one creates no legal presumption about your wishes.
Capacity can be challenged later. If a family member or provider questions whether you were competent when you signed, a court can review the issue years after the fact. If there’s any realistic chance of a challenge, ask a physician to document your mental status around the time of signing.
Who You Can Name as Your Agent
Your agent is the person who will speak for you when you can’t. Wisconsin does not require the agent to live in-state, but someone who can reach a hospital quickly and deal with your medical team in person is a far better choice than a relative several states away. Medical training isn’t necessary; comfort with pushing back on doctors and family members is.
Wisconsin bars certain people from serving as your agent. Your healthcare provider, an employee of that provider, an employee of a facility where you are a patient or resident, and the spouse of any of those people cannot be your agent unless they are also related to you.1Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.05 The restriction prevents the person directing your care from being the same person providing it.
Name a successor agent whenever possible. If your primary agent dies, is incapacitated, or simply can’t be reached in an emergency, a successor steps in without court involvement. Without one, decisions can stall until a court intervenes.
Signing and Witness Rules
A valid Power of Attorney for Health Care must be in writing, dated, signed voluntarily by you (or by someone at least 18 years old signing at your direction and in your presence), and witnessed by two qualified adults.2Wisconsin State Legislature. Wisconsin Statutes 155.10 – Instrument Requirements At the time of signing, neither witness may be any of the following:
- Related to you by blood, marriage, adoption, or domestic partnership.
- An heir or someone who knows they are entitled to any portion of your estate.
- Financially responsible for your healthcare costs.
- Your healthcare provider, or an employee of the provider or facility where you are a patient. Chaplains and social workers at the facility are allowed to witness.
- Your named agent.
In practice, the rules often mean asking neighbors, coworkers, or friends rather than family.
Remote Witnessing
Wisconsin allows witnesses to appear remotely through two-way, real-time audiovisual technology, but only under specific conditions. A licensed Wisconsin attorney must supervise the signing, and that attorney can serve as one of the two witnesses. You and each remote witness must be physically located in Wisconsin, must identify yourselves on camera, and must display photo identification if you don’t already know one another. You also need to show the document on camera and confirm the page count and where you will sign.2Wisconsin State Legislature. Wisconsin Statutes 155.10 – Instrument Requirements The attorney-supervision requirement means remote witnessing is convenient, but not free.
Notarization
Wisconsin does not require notarization. Two qualifying witnesses are enough. Some people notarize anyway for extra verification, and doing so can help if the document’s authenticity is later questioned or if you spend time in a state that requires notarization for its own healthcare directives.
Using the Statutory Form or a Custom One
Wisconsin provides a standard statutory form under Section 155.30, available through the Wisconsin Department of Health Services as Form F-00085.3Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.30 You are not required to use it. A custom document drafted by an attorney is equally valid as long as it meets every Chapter 155 requirement. The statutory form has the advantage of being compliant out of the box, includes the legally required notice to the principal, and costs nothing.
If you use something other than the statutory version, it must contain either the notice spelled out in the statute or a certificate signed by your attorney confirming they have advised you about your rights.3Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.30 Skipping both the notice and the attorney certificate can invalidate the entire document.
When Your Agent’s Authority Begins
Signing does not hand over any authority immediately. Your agent’s powers activate only after two physicians, or one physician and one licensed advanced practice clinician, personally examine you and sign a written statement that you lack the capacity to make your own healthcare decisions.1Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.05 You can specify a different activation trigger in your document, but the two-examiner default is what applies if you don’t.
Capacity assessments generally evaluate four things: whether you understand the medical information being presented, whether you appreciate how it applies to your situation, whether you can reason through the options, and whether you can communicate a choice. Once incapacity is established, the findings go into your medical record, and providers must consult that documentation before recognizing your agent’s authority.
If anyone disputes the finding, interested parties can ask a court to review it. If a court later determines you have regained capacity, your agent’s authority stops and you are back in charge of your own decisions.
What Your Agent Can and Cannot Decide
Once activated, your agent steps into your shoes for healthcare decisions. They can consent to or refuse treatments, approve surgeries, and direct the use of life-sustaining procedures based on the wishes you expressed in the document or communicated directly.4Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.20 Your agent has priority over any other person, including family, as long as providers know the agent is available.
The authority is limited to healthcare. Your agent cannot manage your finances, access your bank accounts, or make legal decisions outside of medical care. For financial matters during incapacity, you need a separate financial power of attorney under Chapter 244.
Mental Health Facility Admission
Your agent cannot consent to admitting you on an inpatient basis to a mental health institution, an intermediate care facility for individuals with intellectual disabilities, a state treatment facility, or a treatment facility as defined under Wisconsin law.4Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.20 Admission to those facilities happens only through the separate processes under Chapters 51 or 55. There is no workaround, even if your document tries to grant the power expressly.
Feeding Tubes and Nutrition
The rules around feeding tubes are more nuanced than most people expect. Your agent can consent to withholding or withdrawing a feeding tube only if your Power of Attorney for Health Care specifically authorizes it. Even then, the agent cannot do so if your attending healthcare professional advises that removing the tube would cause you pain or reduce your comfort.4Wisconsin State Legislature. Wisconsin Code 155 – Power of Attorney for Health Care – Section 155.20 For orally ingested food and water, the standard is stricter: your agent cannot consent to withholding those unless providing them is medically contraindicated. If feeding tube decisions matter to you, address them explicitly. Silence on the topic means your agent lacks the authority.
Changing or Revoking the Document
You can revoke your Power of Attorney for Health Care at any time, as long as you can express that intent. Wisconsin recognizes four methods:5Wisconsin State Legislature. Wisconsin Code 155 – Revocation of Power of Attorney for Health Care – Section 155.40
- Cancel, tear, burn, or otherwise destroy the document, or direct someone to destroy it in your presence.
- Sign and date a written statement expressing your intent to revoke.
- State your intent to revoke in the presence of two witnesses.
- Sign a new Power of Attorney for Health Care, which automatically revokes the prior one.
The two-witness requirement for verbal revocation trips people up. Telling your doctor or one family member you want to revoke is not enough on its own; two people must be present when you say it.
Divorce or annulment automatically revokes the designation if your spouse was your agent. The same applies if your domestic partner was your agent and the partnership is terminated. This revocation is absolute, and the document cannot override it with a clause saying the designation survives divorce.5Wisconsin State Legislature. Wisconsin Code 155 – Revocation of Power of Attorney for Health Care – Section 155.40 If you divorce and still want your former spouse to serve as your agent, you need to sign a new document after the divorce is final.
If you are adjudicated incompetent after signing, the document stays in effect. A court can revoke it or limit the agent’s authority for good cause.6Wisconsin State Legislature. Wisconsin Statutes 155.40 – Revocation of Power of Attorney for Health Care Once revocation happens by any method, your healthcare provider must record the time, date, and place in your medical record. If your former agent knows about the revocation, they are legally required to notify any provider they know has a copy of the old document.
