4.3 Special Identification Situations

Key Takeaways

  • Foreign nationals may be identified by a current foreign passport or other qualifying photo-and-signature ID; U.S. citizenship is never required
  • An agent signing under a power of attorney must be identified personally; the notary verifies identity, not the legal validity of the agent's authority
  • Maine RON (effective July 1, 2023) requires personal knowledge, a credible witness, or at least two types of identity proofing such as credential analysis plus knowledge-based authentication
  • RON sessions must use a Secretary of State-approved platform with two-way audio-video, and the recording must be retained for 10 years
  • When identity, willingness, or basic awareness cannot be established, the notary must refuse the act

Foreign Nationals

A notary serves anyone who appears with valid evidence of identity — there is no citizenship or residency requirement. The most reliable ID for a non-citizen is a current foreign passport bearing a photo. Other qualifying documents include a permanent resident card or an employment authorization document.

ID for foreign nationalsNotes
Foreign passportMost common; must be current with photo
Permanent resident cardUSCIS-issued
Employment authorization documentWork permit, photo present
U.S. visaOften inside the foreign passport

Language barrier rule: A notary may proceed only if able to communicate directly with the signer about the act; Maine does not permit notarizing through a third-party translator, because the notary must personally confirm the signer's willingness and basic understanding. If you cannot communicate directly, decline.

Representatives and Agents

When a person signs on behalf of another — as attorney-in-fact under a power of attorney, as a corporate officer, or as a trustee — the notary's identification duty attaches to the individual physically present, not the absent principal.

Power of attorney: a critical exam distinction

The notary identifies the agent and records the represented capacity in the certificate, for example: "...acknowledged before me by John Smith as attorney-in-fact for Mary Smith..." Under RULONA, the notary is not the guarantor of the agent's legal authority — verifying that the power of attorney is valid and covers the transaction is the responsibility of the parties and any reviewing attorney or title company. The notary's hard requirement is positively identifying the human signer.

Signature by Mark

A signer who cannot write due to disability, injury, or illiteracy may sign by mark (typically an "X"). Identity is still verified normally. Best practice:

  1. The signer makes the mark in the notary's presence.
  2. Two disinterested witnesses observe and sign beside the mark.
  3. The signer's name is written near the mark.
  4. The certificate notes that the signature was made by mark.

Remote Online Notarization (RON)

Maine authorized RON under RULONA effective July 1, 2023, with permanent rules effective October 2, 2023. Before performing RON, a notary must file a Notice to Perform Electronic and/or Remote Online Notarizations with the Secretary of State and await acceptance, and may only use a state-approved communication-technology platform — generic apps like Zoom or FaceTime are not permitted.

Identity of a remotely located individual is established by one of:

RON identity methodWhat it involves
Personal knowledgeNotary already knows the remote signer
Credible witnessWitness (in person or remote) on oath vouches for the signer
Two identity-proofing methodsTypically credential analysis (digital check of the ID) plus knowledge-based authentication (KBA)

Knowledge-based authentication presents questions drawn from public/commercial records that only the genuine signer should answer correctly. Maine RON also requires two-way live audio-video, a mandatory journal entry, and an audio-visual recording retained for 10 years.

Vulnerable and Senior Signers

Notaries verify identity normally for elderly signers, then watch for two non-identity issues:

ConcernNotary action
WillingnessConfirm the signing is voluntary, free of coercion
Basic awarenessConfirm the signer appears to know what is being signed

A notary is not qualified to judge mental capacity. If serious doubt exists, suggest the signer consult an attorney and decline rather than guess.

When You Must Refuse

SituationAction
Identity cannot be establishedRefuse
ID appears fraudulentRefuse and document
Signer appears coercedRefuse and document
Signer plainly does not understandDecline; suggest attorney
Cannot communicate directly with signerDecline

Worked example: A man appears as attorney-in-fact for his mother and shows a valid Maine driver's license and the power of attorney. The notary confirms his identity from the license, completes the acknowledgment noting his attorney-in-fact capacity, and does not attempt to rule on whether the power of attorney is legally sufficient — that judgment belongs to the parties, not the notary.

RON Versus In-Person: What Changes and What Stays

New RON notaries often over-think this. The standard (reasonable certainty of identity) is identical; only the toolkit changes because the signer is not physically present.

ElementIn-personRemote (RON)
Identity by personal knowledgeAllowedAllowed
Credible witnessAllowedAllowed (may appear remotely)
Plain visual ID inspectionSufficientNot sufficient alone
Credential analysis + KBANot usedRequired if not using the above
Recording of sessionNone requiredAudio-video, retained 10 years
PlatformAny settingSOS-approved technology only

The big takeaway: in person, looking at a genuine government ID can carry the act; remotely, an ID by itself is never enough — it must be paired with a second identity-proofing method, or replaced by personal knowledge or a credible witness.

Common Special-Situation Traps

  • Translator trap: Using a friend or relative to translate for a signer the notary cannot understand is not allowed; the notary must communicate directly, so decline if there is a true language barrier.
  • Capacity trap: A notary cannot certify mental competence; observing willingness and basic awareness is the limit, and serious doubt means decline and refer to an attorney.
  • Authority trap: For agents, officers, and trustees, identify the person present; do not assume the notary must validate the represented authority.
  • Citizenship trap: A signer's immigration status is irrelevant to whether you may notarize; only valid identity evidence and the other notarial preconditions matter.

Tying It Together

Every special scenario is the same test applied to harder facts. Identify the human being in front of you (or on the approved video link) to a reasonable certainty, confirm the act is voluntary and at least minimally understood, note the relevant capacity in the certificate, journal the act, and refuse the moment any of those preconditions cannot be met. Mastering that single loop lets you answer nearly any special-situation question on the Maine exam without memorizing every edge case.
