Notarial Certificates

Every notarial act must be documented with a proper notarial certificate. The certificate serves as the official record of what the notary did, when, and for whom. Using the wrong certificate or omitting required elements can invalidate the notarization.

What Is a Notarial Certificate?

A notarial certificate is a written statement by the notary that:

  • Describes the notarial act performed
  • Identifies when and where it was performed
  • Contains the notary's signature and seal
  • Provides authentication for the document

Required Certificate Elements

Every Ohio notarial certificate must include:

ElementDescription
VenueState and county where notarization occurred
DateDate the notarial act was performed
Type of actWhether acknowledgment, jurat, etc.
Signer identificationStatement of how signer was identified
Notary signatureNotary's handwritten signature
Notary seal/stampOfficial Ohio notary seal
Commission expirationWhen notary's commission expires

Matching Certificate to Act

Critical Rule: The certificate must match the type of notarial act actually performed.

Act PerformedCertificate Language
Acknowledgment"acknowledged before me"
Jurat"subscribed and sworn before me"
Affirmation"subscribed and affirmed before me"

Violation Example: If you administer an oath and have the signer sign before you (jurat), but use an acknowledgment certificate, you have committed notary misconduct.

Where Certificates Appear

Pre-printed on Document

Many legal documents have notarial certificates pre-printed:

  • Deeds
  • Affidavits
  • Powers of attorney
  • Mortgage documents

Notary's duty: Verify the pre-printed certificate matches the act you're performing. If it doesn't, use a separate certificate.

Loose Certificates

When a document does NOT have a certificate, the notary may:

  1. Use a loose certificate (separate page)
  2. Attach it to the document
  3. Include identifying information to link the certificate to the document

Loose Certificate Requirements

When using a loose certificate, include:

InformationPurpose
Document descriptionWhat document is being notarized
Number of pagesIdentifies the complete document
Signer's nameLinks to specific individual
Date of documentAdditional identification

Certificate Do's and Don'ts

DO:

  • Verify certificate matches the act performed
  • Fill in all blanks completely

DON'T:

  • Leave blanks unfilled
