Acceptable Identification

Verifying the identity of the signer is one of the notary's most important duties. New Jersey law specifies what forms of identification are acceptable.

Methods of Identification

New Jersey recognizes three methods for verifying a signer's identity:

MethodDescriptionWhen Used

Satisfactory Evidence (ID Documents)

The primary method of identification is presenting a valid government-issued identification document.

Personal Knowledge

A notary may identify a signer based on personal knowledge if:

RequirementDetails

DocumentationNote in journal that ID was by personal knowledge

Important: Personal knowledge means you personally know the signer—not that someone told you who they are. Casual or brief encounters are not sufficient.

When Personal Knowledge Is Appropriate

  • Long-time friend or family member
  • Regular business associate
  • Neighbor you've known for years

When Personal Knowledge Is NOT Appropriate

  • Someone you just met
  • Someone introduced to you by another
  • Someone you recognize but don't really know

Credible Witness Identification

When a signer has no acceptable ID and the notary doesn't personally know them, a credible witness may vouch for the signer's identity.

Credible Witness Requirements

RequirementDetails
Personally Knows SignerMust know signer's identity
Known to NotaryNotary must know witness OR witness presents ID
No InterestCannot benefit from transaction
Takes OathMust swear to signer's identity

Credible Witness Process

  1. Witness personally appears before notary
  2. Notary verifies witness's identity (ID or personal knowledge)
  3. Witness takes oath that they know the signer
  4. Witness vouches for signer's identity
  5. Notary documents the procedure in journal

On the Exam

Expect 3-4 questions on identification:

  • Primary method: Government-issued photo ID
  • ID requirements: Current, photo, signature
  • Personal knowledge: Must personally know—not just recognize
  • Credible witness: Must take oath, no interest in transaction
