6.3 Credible Witness Identification

Statutory Basis: C.R.S. 24-21-507(2)(b)

When a signer cannot produce a qualifying identification document, Colorado law provides a fallback: identification by a credible witness. The witness supplies the missing satisfactory evidence by swearing to the signer's identity. This path exists at C.R.S. 24-21-507(2)(b) and is sometimes documented with an affidavit of identity by credible witness.

The Four Pillars a Credible Witness Must Satisfy

Note the symmetry: the notary must identify the witness using the very same standard from Section 6.1 — personal knowledge or a passport/license/government ID current or expired not more than one year. A credible witness does not relax the ID rules; it shifts them onto the witness.

When a Credible Witness Is Appropriate

Step-by-Step Procedure

1. Signer appears without a qualifying credential.
2. Credible witness appears in person alongside the signer (or via approved audio-video for RON).
3. Notary identifies the witness — by personal knowledge or by inspecting the witness's own qualifying ID.
4. Confirm the relationship — the witness states how they know the signer.
5. Administer the oath or affirmation to the witness.
6. Witness verifies the signer's identity on that oath.
7. Perform the notarial act, then complete the journal.

Sample Oath Wording

"Do you solemnly swear (or affirm) that you personally know [signer's name], that he or she is the person who will be signing this document, and that you have no financial or beneficial interest in this transaction?"

Disqualifying Interest — The Most Tested Trap

A witness may not have a financial or beneficial interest in the transaction. Classic disqualifications:

• A beneficiary named in the document (e.g., the heir under a deed or the payee on a note).
• A party to the transaction, such as the buyer, seller, or grantee.
• A person who is compensated based on the document being signed.

Also remember the notary cannot be the credible witness — those are two separate roles. And the credible witness generally should not be a person named in the very document being notarized.

Journal Entries for a Credible Witness

Good credible witnesses: a long-time friend, a neighbor, a co-worker, or a relative with no stake in the document. Poor choices: a recent acquaintance, a business partner who profits, or anyone listed as a party or beneficiary in the document.

One Witness vs. Two — Colorado's Approach

Some states require two credible witnesses when neither the signer nor either witness is personally known to the notary. Colorado's RULONA framework is built around the witness providing a verification on oath or affirmation of identity; the notary must in turn identify that witness. The cleanest, lowest-risk pattern is a single credible witness whom the notary can identify with a qualifying ID. If the notary cannot identify the witness, the witness adds nothing — the chain of trust breaks. Always ensure the notary's link to the witness is solid before relying on the witness's link to the signer.

Worked Scenario

Maria asks a notary to acknowledge her signature on a vehicle title. Her wallet was stolen, so she has no ID. Her neighbor of twelve years, Devon, comes along. Devon shows a current Colorado driver's license. He is not buying the vehicle and gains nothing from the title transfer.

1. The notary inspects Devon's license — current, photo matches — so the notary now has satisfactory evidence of the witness's identity.
2. Devon states he has known Maria as his next-door neighbor for twelve years.
3. The notary administers the oath; Devon swears Maria is who she claims to be and that he has no interest in the transaction.
4. The notary performs the acknowledgment and records Devon's name, address, and ID in the journal, noting identity was established by credible witness.

If, instead, Devon were the buyer of the vehicle, he would be disqualified by his beneficial interest, and the notary would have to decline or find a disinterested witness.

Pitfalls and Liability

• Do not let the witness coach or speak for the signer beyond the identity verification — the signer must still acknowledge or swear personally.
• Do not accept a witness you cannot identify. "He seems trustworthy" is not a lawful basis.
• Do not use a credible witness to bypass red flags. If the signer's behavior or documents suggest fraud or coercion, refuse the act outright; a willing witness does not cure suspected fraud.
• Document thoroughly. If the act is ever challenged, the journal entry showing how the witness was identified and sworn is the notary's primary defense.
