Updated August 3, 2026. Quick answer: The principal (or another adult signing at the principal’s express direction and in the principal’s physical presence) must sign the power of attorney; that is the only mandatory act. Notarized acknowledgment, or an alternative supervised two-witness remote/videoconference procedure with strict conditions, are not required for basic validity but each independently creates a rebuttable presumption of genuine signature and ‘acknowledged’ status needed to trigger the mandatory third-party acceptance regime.. This state publishes a free official form, linked below. A power of attorney here is durable by default — it survives incapacity unless it says otherwise.

What decides whether the document is valid
The principal (or another adult signing at the principal’s express direction and in the principal’s physical presence) must sign the power of attorney; that is the only mandatory act. Notarized acknowledgment, or an alternative supervised two-witness remote/videoconference procedure with strict conditions, are not required for basic validity but each independently creates a rebuttable presumption of genuine signature and ‘acknowledged’ status needed to trigger the mandatory third-party acceptance regime. Get this wrong and the document is not merely weak — it may be void, and you will find out at the moment somebody needs to use it.
Who may not witness: none stated in the text reviewed (no categorical witness disqualifications found for the remote-witnessing alternative under §244.05) This is the condition that most often fails in practice, because the people in the room are usually the people with an interest.
The free official form
Wisconsin publishes a form at no cost: the official Wisconsin power of attorney form. For a straightforward appointment this is usually all you need, and there is no reason to pay for a copy of it.
Durability — the point most people get wrong
Here a power of attorney is durable by default: it keeps working after the principal loses capacity unless the document says it should not. That is the opposite of the historical rule and it is why old advice about needing magic words can mislead.
Why a springing power often fails when it is needed, and why durable is usually the better default.
If a bank refuses it
Wisconsin addresses this by statute: Yes. Under §244.20, a person asked to accept an acknowledged power of attorney must accept it or request a certification/translation/opinion of counsel (per §244.19) within 10 business days of presentment, and must accept within 5 business days after receiving requested documentation. A court may order acceptance and award reasonable attorney fees and costs against a wrongful refuser (§244.20(5)-(6)).
What the form does not solve
- Social Security will not accept it. No power of attorney works there — a representative-payee application is the only route.
- It has to be signed while capacity is intact. The day that closes, the alternative is a court.
- Name a successor agent. A document whose only named agent has died or declined does nothing — how to choose when there is no obvious person.

If the free form does not fit your situation
Use the official form above first — it is free, it is written to satisfy this state’s own statute, and for a straightforward appointment it is usually all that is needed. Software is worth paying for when the situation outgrows a fixed form: co-agents, successor agents, limits on gifting, or a bank that has already given you trouble.
