Will Requirements in Colorado (2026)
A will in Colorado requires 2 witnesses and does not require notarization. You must be at least 18 years old and of sound mind. Colorado accepts handwritten (holographic) wills, and electronic wills are 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 Colo. Rev. Stat. §15-11-502.
Here's what Colorado 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 Colorado. Congratulations on acknowledging your own mortality. Most people can’t even manage that. Here’s what CO 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
Colorado requires 2 witnesses to make your will valid. Good news: Colorado 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.
Colorado 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
Colorado does accept holographic (handwritten) wills, so technically you could scribble your wishes on a napkin. We don’t recommend it, but you do you. Colorado is one of the forward-thinking states that accepts electronic wills. Welcome to the future of death planning.
What Colorado law says about your stuff
Under Colo. Rev. Stat. §15-11-502, if you die without a will in Colorado, 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 Colorado 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 Colorado?
An attorney in Colorado averages $1,000 (range $600-2000). Killswitch charges $69, once, with no subscription.
Typically $600-2000. The clock starts again every time you think of a question.
Cheap, and you're the one deciding whether it clears Colorado law.
One payment, about thirty minutes, and nobody bills you for the follow-up call. That's roughly $931 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 Colorado?
How many witnesses do I need for a will in Colorado?
Colorado 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 Colorado require a notary for wills?
No, Colorado 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 Colorado?
Yes, Colorado 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.

You must be at least 18 years old to make a will in Colorado. If you're 18 and already thinking about your will, you're either incredibly responsible or having a really rough week.
