NOTARY PUBLIC SERVICES
OATHS AND AFFIRMATIONS
An oath is a promise to a deity and an affirmation is a pledge on one's personal honor. Both are legally binding promises to tell the truth and subject the oath-taker or affirmant to penalties for perjury.
The purpose of an acknowledgement is for an affiant, whose identity has been verified, to declare to a notary public that he or she has willingly signed an affidavit.
The purpose of a jurat is for an affiant to swear to or affirm the truthfulness of the contents of an affidavit. A notary public administers an oath or affirmation to the affiant, who verifies the truths listed in the affidavit under penalty of perjury.
