Oaths and Affirmations

Oaths and affirmations are verbal pledges that carry legal consequences. Understanding how to properly administer them is crucial.

Definitions

Oath

An oath is a formal declaration that invokes a deity or higher power. Example: "Do you solemnly swear that the statements in this document are true, so help you God?"

Affirmation

An affirmation is a formal declaration without religious reference, but with the same legal force. Example: "Do you solemnly affirm, under penalty of perjury, that the statements in this document are true and correct?"

  3. Require response - Signer must verbally respond (e.g., "I do")
  4. Witness signature - Watch signer sign document
  5. Complete certificate - Fill out jurat certificate
  6. Record in journal - Document the notarial act

This omission can invalidate the notarization!
