At the heart of every notarized document—whether it is a home mortgage, a business contract, or a sensitive healthcare directive—lies a single, critical act: Identity Verification. Under the Revised Uniform Law on Notarial Acts (RULONA), which governs Colorado notaries, this is the most important safeguard against fraud, coercion, and identity theft.
Regardless of the setting—be it a corporate boardroom in Denver, a coffee shop in Boulder, or a hospital bedside in Colorado Springs—verifying identity is a rigorous process required by state law to ensure the legal integrity of your most important documents.
Why Identity Verification Matters in Colorado
The notary’s primary duty is to serve as an impartial witness. According to C.R.S. 24-21-507, a Colorado notary must have “satisfactory evidence” of the signer’s identity. By verifying a person’s identity, the notary guarantees to the world that the person who signed the document is exactly who they claim to be.
This prevents “impersonation fraud,” where a bad actor might attempt to forge a signature on a deed or sign away a vulnerable person’s medical rights. Without proper verification, a document is vulnerable to legal challenges that can cost thousands of dollars in Colorado courts.
The Colorado Standard: Satisfactory Evidence
In Colorado, “satisfactory evidence” is strictly defined. The most common way a notary verifies identity is through a valid, current, government-issued identification. Under Colorado law, the ID must contain:
- A Photograph: To match the physical person standing before the notary.
- A Signature: To compare against the signature being placed on the legal document.
Commonly accepted forms of ID in Colorado include:
- Colorado Driver’s Licenses or State-issued ID cards.
- U.S. Passports or Foreign Passports (recognized by the U.S. Dept. of State).
- U.S. Military ID cards.
- Permanent Resident Cards (“Green Cards”).
- Tribal identification cards issued by a federally recognized tribe.
Challenges Across Different Notary Settings
While identity verification is a universal requirement, the challenges vary depending on the type of notary job:
1. General Business & Real Estate
In professional settings, the most common issue is a “Name Match” discrepancy. If a legal document includes a middle name or a hyphenated last name that isn’t on the ID, the notary must ensure the names are substantially similar to prevent the transaction from being rejected by the County Clerk and Recorder.
2. Hospital and Senior Care Settings
Specialized environments require additional patience. It is common for seniors or long-term hospital patients to have let their driver’s licenses expire. In Colorado, an expired ID is generally not considered “current” or valid for notarization.
3. The “Missing ID” Scenario (Credible Witnesses)
If a signer has lost their ID or it has been stolen, Colorado law allows for the use of a Credible Witness. This involves a person who personally knows the signer and has a valid ID themselves. The witness must swear or affirm under penalty of perjury that the signer is who they claim to be.
Beyond the ID: Assessing Awareness and Willingness
While a verification check starts with a plastic card, Colorado law also requires the notary to ensure the signer is:
- Alert and Aware: The signer must understand the significance of the act.
- Acting of Free Will: The signer must not be under duress or undue influence from a third party.
The UPL Boundary: It is important to note that while I verify who you are and that you are signing willingly, I cannot explain the legal terminology within your document or advise you on its consequences. In Colorado, a non-attorney notary who gives legal advice is in violation of C.R.S. 24-21-525 regarding the Unauthorized Practice of Law (UPL).
Colorado FAQ
1. Can a Colorado notary use a Social Security card?
No. Under RULONA, an ID must contain a photograph and a signature. A Social Security card lacks both and is not “satisfactory evidence.”
2. What if my Colorado Driver’s License expired last month?
In Colorado, the ID must be current. If your ID is expired, we must look for a valid passport or utilize the Credible Witness process.
3. Can I show the notary a photo of my ID on my phone?
No. Colorado law requires the notary to examine the physical, original identification to verify its security features.
4. What about Remote Online Notarization (RON)?
Colorado allows for RON, which involves a different verification process called “Identity Proofing” (knowledge-based authentication and credential analysis). However, for in-person mobile notary work, a physical ID is the standard.
