3.3 Credible Identifying Witness Rules

In statutory situations where a principal signer does not possess acceptable physical identification credentials and is not personally known to the notary public, Illinois law permits identity verification through a credible identifying witness (also known as a credible witness). Defined under 5 ILCS 312/6-102 and detailed in Illinois Administrative Code Part 176 (Section 176.400), the credible witness serves as a human bridge of identity between the unknown principal and the notary public.


When to Use a Credible Identifying Witness

A credible identifying witness is an emergency identification mechanism designed for situations where:

  • The principal signer has lost their identification (e.g., stolen wallet, natural disaster).
  • The principal is elderly, infirm, or institutionalized in a healthcare facility and no longer maintains an active driver's license or state ID.
  • The principal is a minor who has not yet been issued government photo identification.

Prerequisite Rule: A credible witness may only be used when the principal signer truly lacks acceptable physical ID and cannot reasonably obtain one. It cannot be used merely as a convenience to avoid looking for a driver's license left in a vehicle.


Statutory Qualifications for the Credible Witness

Under Illinois statutory standards, a credible witness must fulfill three strict legal requirements:

+-------------------------------------------------------------------+
|               CREDIBLE WITNESS STATUTORY TRIAD                    |
+-------------------------------------------------------------------+
| 1. Must personally know the principal signer                      |
| 2. Must be personally known to the notary OR present valid ID    |
| 3. Must be completely IMPARTIAL (no interest in the transaction)  |
+-------------------------------------------------------------------+

Detailed Breakdown of Qualifications

  1. Personal Knowledge of the Principal: The credible witness must have long-standing personal acquaintance with the principal signer, leaving no doubt regarding their true legal name and identity.
  2. Relationship to the Notary:
    • Option A: The credible witness is personally known to the notary public through long-standing acquaintance.
    • Option B: The credible witness presents an acceptable unexpired government ID (driver's license, passport, military ID) to the notary.
  3. Strict Impartiality: The witness must have no financial, beneficial, or legal interest in the document or underlying transaction, and must not be named as a party in the document.

Impartiality & Financial Interest Rules

The requirement of impartiality is heavily tested on the Illinois Notary exam. A credible witness must be a disinterested third party. If a witness stands to gain or lose anything of value from the execution of the document, their testimony is legally compromised.

Loan Officer / BrokerWitnessing a loan closing package to earn a transaction feeDISQUALIFIEDFinancial interest tied to the successful closing of the loan.
Co-worker (No financial stake)Witnessing an affidavit of name change for a colleagueQUALIFIEDPersonal knowledge of principal, no personal stake in the document.

Administering the Oath or Affirmation

Before relying on the testimony of a credible witness, the notary public must formally place the witness under oath or affirmation. Verifying identity via a credible witness without administering an oath invalidates the notarization and constitutes official misconduct.

Mandatory Oath / Affirmation Script

The notary must have the credible witness raise their right hand and state:

Formal Oath: "Do you solemnly swear, under penalty of perjury, that you personally know this individual as [Legal Name of Principal], that this individual is the person named in this document, and that you have no financial or beneficial interest in this document or transaction, so help you God?"

Formal Affirmation: "Do you solemnly affirm, under penalty of perjury, that you personally know this individual as [Legal Name of Principal], that this individual is the person named in this document, and that you have no financial or beneficial interest in this document or transaction?"

The credible witness must verbally and audibly respond with "I do."


Mandatory Journal Entry Requirements

Under Ill. Admin. Code tit. 14, § 176.560, every Illinois notary must maintain a sequential journal of all notarial acts. When identity is established via a credible witness, specific details must be meticulously documented in the journal entry.

Required Journal Fields for Credible Witness Transactions

  1. Date and Time: Exact time of the notarial act.
  2. Type of Notarial Act: (e.g., Acknowledgment, Oath/Affirmation).
  3. Title / Description of Document: (e.g., Power of Attorney for Healthcare).
  4. Principal's Information: Full legal name and signature of the principal signer.
  5. Credible Witness's Full Name & Address: Legible printed name and residential address of the credible witness.
  6. Witness Identity Method: Note whether the witness was "Personally Known to Notary" or record the witness's government ID details (issuing state, ID number, expiration date).
  7. Witness Signature: The credible witness must sign the notary's journal alongside the principal's signature block.

Step-by-Step Credible Witness Workflow

When executing a notarization involving a credible witness, follow this sequential 6-step workflow:

  1. Confirm Lack of Physical ID: Verify that the principal signer truly lacks acceptable government photo ID and cannot obtain one immediately.
  2. Assess Witness Qualifications: Confirm the proposed witness personally knows the principal, is disinterested, and possesses valid ID (or personal knowledge by the notary).
  3. Administer Oath/Affirmation: Have the witness raise their right hand and recite the mandatory oath/affirmation confirming identity and impartiality.
  4. Examine Witness ID: If the witness is not personally known, inspect their government ID for photo, signature, physical description, and current expiration.
  5. Complete Notary Journal: Record all transaction details, principal signature, witness contact info, witness ID data, and obtain the witness's signature in the journal.
  6. Execute Notarial Certificate: Complete the notarial certificate on the document, noting that identity was established via sworn credible witness under 5 ILCS 312/6-102.
