Jurats, Oaths, and Affirmations

While acknowledgments are the most common notarial act, jurats are equally important and frequently tested. The key difference is that a jurat requires an oath about the document's contents AND the signature must be made in the notary's presence.

What Is a Jurat?

A jurat is a notarial act in which BOTH of the following occur:

  1. The signer gives an oath or affirmation that the statements in the document are true and correct
  2. The signer signs the document in the presence of the notary

The Oath or Affirmation Requirement

Ohio law specifies that the notary must administer an oath or affirmation using one of these questions (or substantially similar wording):

Oath Form

"Do you solemnly swear that the statements in this document are true, so help you God?"

Affirmation Form

"Do you affirm, under penalty of perjury, that the statements in this document are true?"

Important: The signer chooses whether to take an oath or affirmation. If they have conscientious objections to oaths (religious or otherwise), they may take an affirmation instead. Both have identical legal effect.

Signature in Notary's Presence

Unlike acknowledgments, the signer MUST sign the document while the notary watches. If the document is already signed, the signer may:

  • Sign again in the notary's presence, OR
  • Strike through the existing signature and sign again

Certificate language"Subscribed and sworn/affirmed""Acknowledged before me"
Common usesAffidavits, sworn statementsDeeds, contracts, powers of attorney

Jurat Certificate Language

A proper jurat certificate should include:

ElementPurpose
"Subscribed and sworn"Indicates oath was administered
"Subscribed and affirmed"Alternative if affirmation was used
Date of notarizationWhen oath was taken
Location (state/county)Jurisdiction
Notary signature and sealAuthentication

Sample Jurat Certificate

State of Ohio, County of ____________

Subscribed and sworn (or affirmed) before me this _____ day of _________, 20


Notary Public, State of Ohio My Commission Expires: ____________

Critical Rule: Match Certificate to Act

Ohio Law Requirement: A notary public shall NOT use a jurat certificate when no oath or affirmation was administered.

Conversely, a notary shall NOT use an acknowledgment certificate when an oath or affirmation WAS administered.

Using the wrong certificate type:

  • Creates an invalid notarization
  • May constitute notary misconduct
  • Could lead to disciplinary action

When to Use a Jurat

Common documents requiring a jurat:

Document TypeWhy Jurat Required
AffidavitsSworn statement of facts
DepositionsSworn testimony
Sworn declarationsLegal truth requirement
Some government formsRequire sworn statements

Administering the Oath Properly

Step-by-Step Jurat Process

  1. Verify identity of the signer
  2. Have signer read the document (or confirm they've read it)
  3. Administer the oath — ask the oath/affirmation question
  4. Wait for response — signer must answer "I do" or similar affirmation
  5. Watch the signature — signer signs in your presence
  6. Complete the certificate — fill out the jurat certificate
  7. Affix your seal — stamp the document

On the Exam

Key points tested about jurats:

  • Two requirements: Oath AND signature in presence
  • Certificate matching: Use jurat certificate ONLY if oath was given
  • Oath vs. affirmation: Same legal effect—signer chooses
  • Cannot substitute: An acknowledgment cannot replace a jurat if oath is required
  • Consequence of lying: Perjury (criminal offense)
