Will Requirements in Wisconsin (2026)
A will in Wisconsin requires 2 witnesses and does not require notarization. You must be at least 18 years old and of sound mind. Wisconsin does not accept handwritten (holographic) wills, and electronic wills are not valid here. A self-proving affidavit is available: your witnesses sign a sworn statement before a notary, and the will can then be admitted to probate without them appearing in court. Will execution is governed by Wis. Stat. §853.03.
Here's what Wisconsin says you need to make your last wishes actually count. Spoiler: it's not as bad as you think.

- Put it in writing and sign it yourself.
- Have 2 witnesses watch you sign, then have them sign the will too. Don't pick someone who inherits under it.
- A notary isn't required in Wisconsin, but one is worth finding anyway.
- Attach a self-proving affidavit so your witnesses never have to show up in probate court.
So you’ve decided to finally write a will in Wisconsin. Congratulations on acknowledging your own mortality. Most people can’t even manage that. Here’s what WI law requires to make sure your last wishes actually hold up in court instead of becoming an expensive piece of creative writing.
The basic requirements
Wisconsin requires 2 witnesses to make your will valid. Good news: Wisconsin doesn’t require a notary for your will, though getting one makes it self-proving and saves your executor a headache later. You must be at least 18 years old and of sound mind, though if you’ve been putting this off for years, the “sound mind” part is debatable.
Wisconsin supports self-proving affidavits, which means if you get your witnesses to sign a sworn statement with a notary, they won’t have to show up in court later to confirm they watched you sign. Future-you’s executor will thank present-you.
Handwritten and electronic wills
Wisconsin does NOT accept holographic (handwritten) wills, so put down the napkin and the crayon. Electronic wills aren’t recognized in Wisconsin yet, so you’ll need actual paper like it’s 1995.
What Wisconsin law says about your stuff
As a community property state, your spouse already owns half of everything acquired during the marriage. Your will covers your half and any separate property. Under Wis. Stat. §853.03, if you die without a will in Wisconsin, your assets get distributed according to intestacy laws, basically, the state’s default settings for dead people. These defaults rarely match what anyone actually wants.
The bottom line
A valid will in Wisconsin isn’t complicated, but it does need to follow the rules. 2 witnesses, your signature, and a clear head. Skip any of these and you might as well not bother, your family will be stuck in probate court arguing about who gets the good china while lawyers bill $300 an hour to watch.

How many witnesses do I need for a will in Wisconsin?
