Power of Attorney Requirements in Wisconsin

At a glance

Requirements one by one

Governing law

The Uniform Power of Attorney for Finances and Property Act, Wis. Stat. ch. 244 (§ 244.01). A power of attorney "executed in this state on or after September 1, 2010, is valid if its execution complies with s. 244.05" (§ 244.06(1)).

Who must sign

The principal, or, "at the express direction and in the physical presence of the principal," an individual 18 or older who signs the principal's name on the document (§ 244.05(1)).

Notarization

Optional. It does not make an otherwise-valid signature invalid to skip it, but it buys a legal benefit: a signature "is presumed to be genuine if the principal makes an acknowledgment of the power of attorney before a notarial officer authorized under ch. 140" (§ 244.05(2)). Notarization becomes practically required later if the power of attorney needs to be recorded for a real estate transaction — see "Real estate extras" below.

Witnesses

Not required for an ordinary, in-person signing. Witnesses matter only as an alternative route to the same genuineness presumption, and only for a power of attorney signed remotely: two witnesses appearing "via simultaneous remote appearance by 2-way, real-time audiovisual communication technology," with the signing "supervised by an attorney in good standing licensed by this state" (§ 244.05(3), (3)(a)).

Statutory form

Yes. The "WISCONSIN STATUTORY FORM POWER OF ATTORNEY FOR FINANCES AND PROPERTY" (§ 244.61) lets a principal check boxes for the subjects — real property, banking, taxes, and more — they want to delegate.

Durable by default?

Yes. "A power of attorney created under this chapter is durable unless it expressly provides that it is terminated by the incapacity of the principal" (§ 244.04).

Springing POA allowed?

Yes. A power of attorney "is effective when executed unless the principal provides in the power of attorney that it becomes effective at a future date or upon the occurrence of a future event or contingency" (§ 244.09(1)). The principal may name someone to determine that the event happened (§ 244.09(2)). If the trigger is incapacity and no one is named or willing, the power of attorney becomes effective once "a physician" or "a psychologist," or "an attorney at law, a judge, or an appropriate governmental official," determines the principal is incapacitated (§ 244.09(3)(a)-(b)).

Real estate extras

Chapter 244 itself adds nothing beyond ordinary execution — it only defines what "general authority" over real property lets an agent do (§ 244.44), not any special signing or recording step. But recording a power of attorney to support a real estate transaction pulls in Wisconsin's general instrument-recording law: any document "offered for record" must "bear such signatures as are required by law" and "contain a form of authentication authorized by s. 706.06 or ch. 140" — in practice, a notarial acknowledgment (Wis. Stat. § 706.05(2)(a)-(b)).

Out-of-state POAs

Recognized. A power of attorney "executed outside this state is valid in this state if, when the power of attorney was executed, the execution complied with ... the law of the jurisdiction that determines the meaning and effect of the power of attorney" (§ 244.06(3)(a)). That governing jurisdiction is "the jurisdiction indicated in the power of attorney" or, absent one, "the jurisdiction in which the power of attorney was executed" (§ 244.07(1)). Copies count too: "a photocopy or electronically transmitted copy of an original power of attorney has the same effect as the original" (§ 244.06(4)).

What trips people up

• Skipping notarization because it isn't required. It's optional for validity, but an unnotarized power of attorney can't be recorded for a real estate transaction, and most banks expect notarization anyway even though the statute doesn't demand it (§ 244.05(2), Wis. Stat. § 706.05(2)(b)).
• Assuming witnesses are needed. They're not, for a normal in-person signing; the two-witness route in § 244.05(3) is a remote-signing alternative, not a general requirement.
• Assuming durability needs special language. In Wisconsin it's the opposite: silence keeps the default; you'd need language ending authority at incapacity to opt out (§ 244.04).
• Not naming a jurisdiction for an out-of-state document. Without one named in the power of attorney, the governing law defaults to wherever it was executed (§ 244.07(1)).

Common questions

Does Wisconsin require notarization or witnesses? Neither is required for an ordinary power of attorney; the principal's signature alone is enough (§ 244.05(1)). Notarization only adds a presumption of genuineness (§ 244.05(2)).

Is a Wisconsin power of attorney durable automatically? Yes, unless the document says it ends at your incapacity (§ 244.04).

Is there an official Wisconsin power of attorney form? Yes, the Wisconsin Statutory Form Power of Attorney for Finances and Property (§ 244.61).

Can it take effect only if I become incapacitated later? Yes. Name someone to determine that in writing; without a willing, named person, a physician or psychologist, or an attorney, judge, or government official, can make that determination instead (§ 244.09(1)-(3)).

Will my out-of-state power of attorney work in Wisconsin? Yes, if its execution complied with the law of the jurisdiction that governs it — the one named in the document, or the one where it was executed if none is named (§ 244.06(3)(a), § 244.07(1)).
