How to Make a Will in Wisconsin (2026): Requirements, Witnesses, Self-Proving Affidavit

Updated August 4, 2026. Quick answer for Wisconsin: nobody publishes a reliable, state-specific median for what a will costs here, and the figures you will see quoted — including ours — are national. Anyone showing you a precise Wisconsin number is estimating. What is genuinely Wisconsin-specific, and what actually decides whether your will works, is how it has to be executed. The detail worth knowing before you sign anything: Wisconsin is one of the few states we can verify that publishes a complete statutory will form in its own code — a free, official starting point most states do not give you.

Putting a loan in writing? The interest limit, the signing rules and the time limit to sue, from the state’s own statutes: Wisconsin promissory note.

The honest position on Wisconsin pricing

We publish a national attorney median for a simple will of $625 (middle 50% $450–$1,000) and a DIY platform range of $129–$599. Attorney figures are the national medians from the LegalTemplates 2026 survey of 909 firms, verified July 23, 2026. They are national, not state-specific. Geographic multipliers are widely republished, but the primary source for them blocks automated verification, so we will not apply one to Wisconsin and present the result as a Wisconsin figure. When a defensible state-level dataset exists, this page will carry it and say where it came from.

What Wisconsin law actually requires

This is the part that is genuinely state-specific, and the part that decides whether the document works at all. Every line below is read from the statute, with the citation attached:

• Witnesses: 2. Wis. Stat. § 853.03(2)(am)
• If a beneficiary witnesses it: the will still stands, but a gift to a witness or the witness’s spouse is invalid to the extent it exceeds what that person would have received had the testator died intestate, unless the will is also signed by 2 disinterested witnesses or there is sufficient evidence that the testator intended the full transfer to take effect (purging statute). Wis. Stat. § 853.07(2)(b), (c)
• Notary required for the will to be valid: no. A notary is not what makes a will valid here — the witnesses are. Wis. Stat. § 853.03
• Self-proving affidavit: available. Signing one at the same time as the will is what saves your executor from tracking witnesses down years later. Wis. Stat. § 853.04
• Handwritten (holographic) wills: no holographic-will provision. Wisconsin requires 2 witnesses (Wis. Stat. § 853.03), but a written will is also validly executed if it complies with the law of the place where it was executed or where the testator resided, was domiciled or was a national (Wis. Stat. § 853.05(1)(b)). Wis. Stat. § 853.03
• Electronic wills: not recognised. Wis. Stat. § 853.03(2)(c) authorizes only simultaneous remote audiovisual witnessing of an otherwise physical will; ch. 853 has no standalone electronic-wills provision

The full 44-jurisdiction comparison is on what each state requires for a will to be valid. Whether a beneficiary may witness is covered nationally on can a beneficiary witness a will, and the notary question on does a will need to be notarised.

Does Wisconsin give you a free form?

Yes. Wisconsin is one of the few states we can verify that publish a complete statutory will form in their own code: the others are California, Maine, Michigan and New Mexico. A statutory form is free and official, but it is deliberately rigid: it handles a simple estate and nothing more.

What skipping it costs in Wisconsin

Wisconsin sets probate compensation on a mixed basis rather than a single percentage schedule. The two numbers that decide what an estate actually pays are the fee basis and the small-estate threshold.

Fee basis: Personal representative commission is statutory (Wis. Stat. §857.05(2)): 2% of the inventory value of property (less mortgages/liens) plus net principal gains, or a rate agreed with the decedent/beneficiaries; court may add for extraordinary services. Attorney fees are ‘just and reasonable’ (Wis. Stat. §851.40 standard). Verified on docs.legis.wisconsin.gov.

Small-estate threshold: $50,000 gross value of property subject to administration in Wisconsin (Wis. Stat. § 867.03).

A will does not avoid probate — it directs it. What it prevents is the estate being distributed by Wisconsin’s intestacy statute instead of by you, and it lets you name the executor rather than leaving the court to appoint one. The arithmetic on the other side is on what probate costs in Wisconsin.
