Notaries are authorized to administer an oath or affirmation for a deposition to the witness or deponent for use in court or on an investigation. The deponent must be physically present and be properly identified. Notaries who keep a journal should make an entry at this point obtaining also the deponent’s signature. A notary would then administer the oath or affirmation asking (may have the person raise his or her right hand):
“Do you swear (or affirm) that the testimony you are about to give in this matter is the truth, the whole truth, and nothing but the truth (so help you, God)?”
Once the answer is “yes,” the deponent is under oath, and the duty of the notary is over!
