What the rule says
Wisconsin adopted the Power of Attorney for Finances and Property Act effective September 1, 2010, codified at Wis. Stat. § 244.01 et seq. The Act is Wisconsin's enactment of the Uniform Power of Attorney Act framework.
Default durability
A Wisconsin POA is durable by default — the agent's authority survives the principal's incapacity unless the document expressly states otherwise.
Specific powers
Under Wis. Stat. § 244.41, certain powers require express authorization:
- Making a gift - Creating, amending, modifying, revoking, or terminating an inter vivos trust - Creating or changing rights of survivorship - Creating or changing a beneficiary designation - Disclaiming property - Delegating fiduciary authority
Third-party acceptance
Under Wis. Stat. § 244.20, third parties (banks, brokers, etc.) generally must accept properly executed Wisconsin POAs.
Marital property considerations
Like Washington and Arizona, Wisconsin's marital property regime adds a wrinkle to POA planning. A POA from one spouse alone may not provide complete authority over marital property; coordination with the other spouse is often necessary for transactions affecting marital property.
Execution requirements
A valid Wisconsin POA must be:
- Signed by the principal - Acknowledged before a notary public
Healthcare power of attorney is separate
Wisconsin separates property and healthcare frameworks. Healthcare decisions require a separate Wisconsin Power of Attorney for Health Care under Wis. Stat. § 155.01 et seq.
What happens without a POA
If a Wisconsin resident becomes incapacitated without an executed durable POA, the family must seek guardianship under Wis. Stat. § 54.
What you can do about it
For Wisconsin residents:
- Execute a Power of Attorney for Finances and Property. - Acknowledge before a notary. - Specifically enumerate hot powers if needed. - Designate a successor agent. - Coordinate spousal POAs for marital property considerations. - Coordinate with the Power of Attorney for Health Care. - Update older POAs.
Who this affects most
WI's POA framework is most consequential for Wisconsin adults without executed POAs and married couples whose POAs need to coordinate with marital property rules.
