Will Requirements in Wyoming (2026)
A will in Wyoming requires 2 witnesses and does not require notarization. You must be at least 18 years old and of sound mind. Wyoming accepts 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 Wyo. Stat. §2-6-112.
Here's what Wyoming says you need to make your last wishes actually count. Spoiler: it's not as bad as you think.

So you’ve decided to finally write a will in Wyoming. Congratulations on acknowledging your own mortality. Most people can’t even manage that. Here’s what WY 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
Wyoming requires 2 witnesses to make your will valid. Good news: Wyoming 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.
Wyoming 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
Wyoming does accept holographic (handwritten) wills, so technically you could scribble your wishes on a napkin. We don’t recommend it, but you do you. Electronic wills aren’t recognized in Wyoming yet, so you’ll need actual paper like it’s 1995.
What Wyoming law says about your stuff
Under Wyo. Stat. §2-6-112, if you die without a will in Wyoming, 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 Wyoming 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 much does a will cost in Wyoming?
An attorney in Wyoming averages $700 (range $400-1200). Killswitch charges $69, once, with no subscription.
Typically $400-1200. The clock starts again every time you think of a question.
Cheap, and you're the one deciding whether it clears Wyoming law.
One payment, about thirty minutes, and nobody bills you for the follow-up call. That's roughly $631 you keep.
That's less than your monthly streaming subscriptions, and infinitely more useful when you're dead. Just $69.
What else do people ask about wills in Wyoming?
How many witnesses do I need for a will in Wyoming?
Wyoming requires 2 witnesses for a valid will. They need to be competent adults who watch you sign and then sign the will themselves. Pro tip: don't pick someone who's inheriting, that's a conflict of interest that could invalidate their share.
Does Wyoming require a notary for wills?
No, Wyoming doesn't require a notary for your will to be valid. However, getting a notarized self-proving affidavit means your witnesses won't have to testify in court later, worth the extra step.
Are handwritten wills valid in Wyoming?
Yes, Wyoming recognizes holographic (handwritten) wills. They still need to be entirely in your handwriting and signed by you. No witnesses technically required for holographic wills, but a typed and witnessed will is much harder to contest.
What is the minimum age to make a will in Wyoming?
You must be at least 18 years old to make a will in Wyoming. If you're 18 and already thinking about your will, you're either incredibly responsible or having a really rough week.
