Colorado will requirements (two witnesses or a notary acknowledgment)
You're going to die. Colorado already drafted Plan B for your stuff. C.R.S. §15-11-502 gives you a dual path most states do not: a will in writing, signed by you (or a proxy in conscious presence), and either two individuals who sign within a reasonable time after witnessing, or your acknowledgment of the will before a notary (or other acknowledgment officer).
That notary path is real. It is also not "Killswitch notarizes your PDF." Acknowledgment for validity under §15-11-502(1)(c)(II) is not the same animal as a self-proving package under §15-11-504. Mix those up and you will confuse yourself and possibly a clerk.
The short version
How to sign a will in Colorado
Dual path under C.R.S. §15-11-502(1):
- Path A (product default, matches other states): Will in writing. You sign, or a proxy signs in your conscious presence by your direction. At least two individuals sign within a reasonable time after they witnessed the signing or your acknowledgment of the signature or will.
- Path B (Colorado specialty): Will in writing and signed as above. You acknowledge the will before a notary public or other individual authorized to take acknowledgments (§15-11-502(1)(c)(II)). Witnesses are not required on this path.
Conscious presence means physical proximity. It does not always mean line of sight (§15-11-502(4)). Killswitch's printed instructions default to the two-witness path for consistency with other states. The acknowledgment alternative is real Colorado law. Use a licensed notary or authorized officer if you take Path B. We do not supply that notary. Electronic wills under Title 15 Article 11 Part 13: VERIFY / out of scope for this paper-will page.
Colorado will witnesses
On Path A, a generally competent individual may witness. Signing by an interested witness does not invalidate the will or any provision (§15-11-505).
That is statutory mercy, not a dare. Prefer disinterested pens for contest optics. Label that as practical guidance, not a statutory voiding rule.
On Path B, witnesses are optional because acknowledgment replaces them for execution validity. Do not confuse that with "self-proved."
Do you need a notary for a Colorado will
It depends which path you take.
Witnessed path: notary is not required for §15-11-502 validity. Optional self-proving under §15-11-504 uses acknowledgment plus witness affidavits before an oath officer, with statutory forms, simultaneous or later.
Acknowledgment path: acknowledgment before a notary (or other authorized officer) can satisfy execution instead of two witnesses (§15-11-502(1)(c)(II)). That makes the notary part of validity on that path.
Do not equate a bare acknowledgment under §15-11-502(1)(c)(II) with a self-proved will under §15-11-504. Self-proving is a separate proof package for witnessed wills. Acknowledgment-only wills can still face practical probate friction (educational OK; do not oversell "notary alone is always painless").
Killswitch does not notarize documents and does not offer remote online notarization.
Colorado will mistakes that hurt later
- Thinking Colorado always needs two witnesses. The acknowledgment alternative exists. Cite: §15-11-502(1)(c)(II).
- Thinking a notary acknowledgment is the same as a self-proving affidavit package. Cite: compare §15-11-502(1)(c)(II) with §15-11-504.
- Assuming Killswitch supplies the notary. We do not.
- Proxy signer / conscious presence misunderstandings. Conscious presence is physical proximity under §15-11-502(4), not a Zoom loophole invented for convenience.
What is a holographic will in Colorado
A will is valid as holographic if the signature and material portions are in the testator's handwriting (§15-11-502(2)).
Separate path from the formal witnessed (or acknowledged) will. Killswitch's signing instructions target the formal witnessed path.

Frequently asked questions
How many witnesses for a Colorado will
At least two individuals who sign within a reasonable time after witnessing, or none if the testator instead acknowledges the will before a notary or other acknowledgment officer under C.R.S. §15-11-502(1).
Do I need a notary for a Colorado will
Not if you use two witnesses for validity. Acknowledgment before a notary can replace witnesses under §15-11-502(1)(c)(II). Killswitch does not notarize. A notary or oath officer is also used if you want optional self-proving for a witnessed will under §15-11-504.
Is a Colorado notary acknowledgment the same as self-proving
No. Acknowledgment under §15-11-502(1)(c)(II) can satisfy execution instead of witnesses. Self-proving under §15-11-504 is a separate proof package for wills executed with attesting witnesses.
Can an interested witness sign a Colorado will
Yes. An interested witness does not invalidate the will or any provision under §15-11-505. Prefer disinterested witnesses for contest optics anyway.
Are holographic wills valid in Colorado
Yes, if the signature and material portions are in the testator's handwriting (§15-11-502(2)). This page focuses on formal witnessed or acknowledged wills.
