Will requirements in Colorado
Colorado is one of very few states where a notarized will needs no witnesses at all — notarization is a genuine substitute rather than an add-on — and it recognizes both handwritten and electronic wills.
Colorado offers something almost no other state does: you can make a valid will with no witnesses at all, provided it is acknowledged before a notary. In most states a notary supplements witnesses. In Colorado, notarization is a genuine alternative to them.
That flexibility runs through Colorado's whole approach. Handwritten wills are valid without witnesses, electronic wills are authorized under the Uniform Electronic Wills Act, and a beneficiary who signs as a witness keeps their gift. Colorado is among the most permissive states in the country on execution formalities.
Who can make a will in Colorado
At a glance
18 or older, and of sound mind
C.R.S. § 15-11-501
Colorado requires you to be 18 and of sound mind, judged as at the time of signing. The capacity standard asks whether you understood what you owned, who would naturally inherit, and what the document did.
Witness requirements
How many witnesses
Two witnesses, or a notarized acknowledgment with no witnesses at all
C.R.S. §§ 15-11-502, 15-11-505
No purge — the gift survives
A witness who inherits under the will does not lose the gift
Colorado gives you a real choice. Sign before two witnesses, or acknowledge the will before a notary public with no witnesses at all. Both produce a valid will, and the notarized route is unusual — only a small number of states allow it.
Colorado follows the Uniform Probate Code on interested witnesses, so a beneficiary who signs neither invalidates the will nor loses their gift. Where witnesses are hard to arrange, the notarized route sidesteps the interested-witness question entirely.
Whatever Colorado allows, the safe practice is the same everywhere: use two disinterested witnesses who inherit nothing under the will.
Notarization, self-proving affidavits and electronic wills
At a glance
Notarization can substitute for witnesses entirely; a self-proving affidavit is also available, and Colorado has adopted the Uniform Electronic Wills Act
C.R.S. §§ 15-11-1301 to 15-11-1311
A notary can serve two different functions in Colorado. It can replace the witnesses outright, producing a valid will with no witnesses. Or, on a conventionally witnessed will, it can produce a self-proving affidavit so the witnesses never need to testify.
Colorado has also adopted the Uniform Electronic Wills Act, giving a third execution route with its own requirements. Between witnessed, notarized, handwritten, and electronic wills, Colorado recognises more valid paths than almost any state — though that breadth makes it worth confirming which formalities apply to the route you actually choose.
Handwritten (holographic) wills
At a glance
Recognized if the material portions and the signature are in your own handwriting
C.R.S. § 15-11-502
Colorado accepts holographic wills where the material portions and signature are in your handwriting, with no witnesses required. The document need not be entirely handwritten.
Given that Colorado also allows a notarized will without witnesses, the holographic route is less necessary here than in states where witnesses are the only option. A notarized will is generally easier to prove than a handwritten one.
Small estate procedure
At a glance
Colorado offers a small-estate affidavit below a threshold that is adjusted for inflation, and published sources give differing current figures
Confirm this with the Colorado Judicial Branch probate self-help resources or the district court.
Colorado allows collection of property by affidavit where the estate falls below a statutory threshold, after a short waiting period. The figure is inflation-adjusted, so it moves.
We are not printing a number here because the sources available disagree about the current amount. The Colorado Judicial Branch publishes the applicable figure and the affidavit form.
Community property or common law
At a glance
Common law (separate property) state
Colorado is a common law property state. Ownership follows title rather than being automatically shared because property was acquired during the marriage.
Colorado protects a surviving spouse through an elective share, so a spouse generally cannot be disinherited by will alone. Colorado's elective share is calculated on an augmented estate that can reach beyond probate assets, which is worth understanding if your plan relies on non-probate transfers.
Advance directives and powers of attorney
At a glance
Statutory medical durable power of attorney and living will; Colorado follows the Uniform Power of Attorney Act
Colorado provides a medical durable power of attorney for appointing a health-care agent, and a separate living will declaration for treatment preferences. Colorado also uses CPR directives and MOST forms in medical settings, which are distinct from the advance directive itself.
For financial matters Colorado has adopted the Uniform Power of Attorney Act, which generally makes its statutory form more portable across state lines.
Frequently asked about Colorado wills
- Can I make a valid Colorado will without any witnesses?
- Yes, if it is acknowledged before a notary public. Colorado is one of a small number of states where notarization substitutes for witnesses entirely rather than supplementing them. You can also make a valid holographic will in your own handwriting with no witnesses. Both routes are genuinely valid, though a will signed before two witnesses with a self-proving affidavit remains the most contest-resistant option.
- Is a handwritten will valid in Colorado?
- Yes. Colorado recognises holographic wills where the material portions and signature are in your own handwriting, with no witnesses required. Because Colorado also permits a notarized will without witnesses, the handwritten route is less necessary here than elsewhere — a notarized will is usually easier for your executor to prove.
- Does a beneficiary lose their inheritance by witnessing my Colorado will?
- No. Colorado follows the Uniform Probate Code, so an interested witness neither invalidates the will nor forfeits their gift. Two disinterested witnesses are still the better practice for resisting an undue-influence challenge. Alternatively, using the notarized route avoids the interested-witness question altogether.
- Can I sign a will electronically in Colorado?
- Yes. Colorado has adopted the Uniform Electronic Wills Act, which authorizes electronic wills with their own execution requirements. It is a distinct process, not a scan of a signed paper will. Electronic wills law is developing quickly, so confirm the current requirements with a Colorado attorney before executing one.
This is not legal advice
This page is general information about Colorado law, not legal advice, and reading it does not create an attorney-client relationship. Statutes change, courts interpret them differently, and the right answer depends on facts this page cannot know.
