4.1 Satisfactory Evidence of Identity
Key Takeaways
- MCA 1-5-603 requires identity verification for acknowledgments, jurats, and signature witnessing
- Two lawful methods exist: personal knowledge OR satisfactory evidence of identity
- Satisfactory evidence is documentary proof (a qualifying ID) OR a credible witness's oath
- Personal knowledge demands reasonable certainty from prior dealings, not a vague recollection
- The notary holds final authority to accept, reject, or demand additional identification
The Statutory Foundation
The identity rules tested on the Montana Notary Exam come almost entirely from MCA 1-5-603 (Requirements for certain notarial acts -- personal and remote appearance -- identification methods). The statute states that a notarial officer who takes an acknowledgment, administers a verification on oath or affirmation (a jurat), or witnesses a signature must (1) confirm the individual personally appeared, and (2) be reasonably certain of that individual's identity. "Reasonably certain" is the legal threshold the exam returns to repeatedly.
When Identity Verification Is Required
Not every notarial act demands identity proof. Memorize this split for the exam:
| Notarial Act | Identity of Signer Required? |
|---|---|
| Acknowledgment | YES |
| Verification on oath/affirmation (jurat) | YES |
| Signature witnessing | YES |
| Copy certification | No -- you certify a copy, not a signer |
| Standalone oath/affirmation | Situational; appearance required, ID not always |
Two -- and Only Two -- Lawful Methods
MCA 1-5-603 recognizes exactly two ways to reach "reasonably certain." The exam loves to add fake third options (a phone call, a prior notarization record, a co-worker's say-so). Those are wrong.
Method 1: Personal Knowledge
The notary already knows the individual through prior dealings sufficient to establish, with reasonable certainty, that the person holds the claimed identity. A single past encounter or a faint memory is not enough.
Trap: "You notarized for me last month" does NOT create personal knowledge if the notary does not actually remember the person well enough to be reasonably certain.
Method 2: Satisfactory Evidence
When personal knowledge is absent, the notary obtains satisfactory evidence two ways:
| Sub-method | What It Means |
|---|---|
| Documentary proof | A qualifying government-issued ID (covered in 4.2) |
| Credible witness | A person who swears to the signer's identity (covered in 4.3) |
Worked Example
A stranger asks you to notarize a deed acknowledgment. You have never met her. Personal knowledge is impossible, so you need satisfactory evidence. She hands you a Montana driver's license that expired 14 months ago, the photo matches, and the name matches the deed. That is documentary proof within the 3-year expiration window -- you may proceed. Had she presented no ID, you would fall back to a credible witness; with neither, you must refuse.
The Notary's Final Authority
Even when a signer hands over a technically valid document, the statute leaves the ultimate decision with the notary. The notary may:
- Accept or reject any identification presented
- Require additional identification before proceeding
- Refuse the act entirely if not reasonably certain of identity
This discretion is not arbitrary -- it must be exercised in good faith -- but it means "the ID met the technical rule" is never, by itself, a complete answer on the exam.
Why Identity Sits at the Center of Every Act
Understand the purpose and the rules become easy to apply. A notarization is a public assurance that a particular, identified person personally appeared and signed. If the notary is wrong about who appeared, the entire act is worthless and may facilitate fraud -- a forged deed, a coerced power of attorney, a stolen-identity loan. That is why the identity standard is the gatekeeper for the three substantive acts (acknowledgment, jurat, signature witnessing) and why a failure to verify identity is among the most common grounds for a notary's commission to be revoked and for civil liability.
Two concepts anchor the analysis. Personal appearance means the individual is physically present (or, for Remote Online Notarization, present through approved live audio-video) at the moment of the act -- a signer cannot mail in a signed page and ask you to notarize it later. Reasonable certainty is the confidence level the law demands: not absolute proof, but a sound, good-faith conclusion based on personal knowledge or satisfactory evidence.
The exam will test scenarios that fall just short of reasonable certainty -- a half-remembered face, a borrowed ID, an unsworn say-so -- and expect you to recognize that more verification is required.
Distinguishing the Two Methods in Practice
A practical way to keep the methods straight: personal knowledge is about the relationship between the notary and the signer, while satisfactory evidence is about proof the signer brings to the table. You can never "upgrade" a weak memory into personal knowledge by adding a journal lookup or a co-worker's vouching -- those are neither personal knowledge nor one of the two recognized forms of satisfactory evidence. If personal knowledge is genuinely present, no ID is needed at all; if it is absent, you must land on documentary proof or a credible witness.
There is no blended middle ground, and inventing one is the classic wrong answer that the exam writers deliberately plant in the answer choices.
On the Exam
- Two methods only: personal knowledge OR satisfactory evidence -- reject invented third options.
- Reasonable certainty is the standard for personal knowledge.
- Notary decides: final authority to accept, reject, or require more ID.
- Required for: acknowledgments, jurats, signature witnessings -- not copy certifications.
A signer says, "You notarized for me last month, so you should remember me." The notary does not actually recall the signer. What should the notary do?
