Satisfactory Evidence of Identity

Before performing any notarial act, the notary must verify the identity of the signer. Ohio Revised Code 147.53 specifies the methods for obtaining "satisfactory evidence" of identity.

Two Primary Methods of Identification

Ohio law provides two main ways to identify a signer:

MethodDescription
Personal KnowledgeNotary personally knows the signer
Identification DocumentSigner presents acceptable ID

Additionally, a credible witness may be used when the signer has no acceptable ID.

Method 1: Personal Knowledge

A notary has personal knowledge of the signer's identity when:

  • The signer is personally known to the notary
  • Knowledge was developed through dealings sufficient to provide reasonable certainty
  • The notary is confident the person has the identity claimed

What Constitutes Personal Knowledge?

AcceptableNOT Acceptable
Long-term family memberJust met today
Coworker known for yearsSomeone you recognize from TV
Regular customer you know wellSocial media connection only
Longtime friendIntroduced by a stranger

Important: Personal knowledge requires more than casual acquaintance. You must have reasonable certainty of the person's identity.

Method 2: Identification Documents

The most common method is inspection of an acceptable identification document.

Acceptable Documents

Ohio accepts identification documents that contain:

  • Photograph of the individual
  • Signature of the individual
  • Current OR expired not more than 3 years before the notarial act

Types of Acceptable IDs

Acceptable IDNotes
U.S. PassportCurrent or expired within 3 years
Driver's LicenseAny U.S. state; current or expired within 3 years
Government-issued nondriver IDState ID cards
Other government ID with photo and signatureMilitary ID, etc.

2025 Law Clarification

House Bill 315 (effective April 3, 2025) clarified that acceptable identification:

  • Must contain a photograph AND signature (or be satisfactory to the notary)
  • May be current or expired not more than 3 years before the notarial act
  • The notary retains discretion to decline an ID they find unsatisfactory

What to Check on an ID

ElementWhat to Verify
PhotoDoes it match the person appearing?
NameDoes it match the document being signed?
ExpirationCurrent or expired within 3 years?
Physical descriptionReasonable match to the person?
Signs of tamperingAny alterations or damage?

Method 3: Credible Witness

When the signer cannot present acceptable identification, a credible witness may vouch for their identity.

Credible Witness Requirements

The credible witness must:

  • Be personally appearing before the notary
  • Be personally known to the notary OR present acceptable ID
  • Take an oath affirming the signer's identity
  • Have no financial interest in the transaction

Who Can Be a Credible Witness?

AcceptableNOT Acceptable
Unrelated third party known to notaryThe notary themselves
Person with acceptable ID who knows signerSomeone with financial interest in document
Any disinterested partyParty to the transaction

Notary's Right to Decline

The notary can always decline if not satisfied with the identification presented, even if it technically meets the legal requirements.

Reasons to decline may include:

  • ID appears altered or damaged
  • Photo doesn't match well
  • Something seems "off" about the situation
  • Suspicious circumstances

Identification for Representatives

When someone signs in a representative capacity (for a company, as power of attorney, etc.), the notary should verify:

ForWhat to Verify
Individual IdentitySame as any signer
Representative AuthorityNot required to verify, but recommended to ask

Note: The notary is NOT responsible for verifying that the representative actually has authority—only that they are who they claim to be.

On the Exam
