Glossary of Notary Public, Mortgage, Signing Agent, and Loan Signing Terms.
Phonetics: af·fir·ma·tion \ˌa-fər-'mā-shən\
The person making an affirmation is known as an affiant. An Affirmation is an alternative to taking an Oath and doesn't include a reference to God. Many states have combined the notary acts of Oaths and Affirmations into one official act where the verbiage is flexible to include one variation that has a reference to God and one that includes the term, "Affirm", and no reference to God.
It should be noted, that during an affirmation, the affiant should ideally raise their right hand before they make their affirmation. Affiants typically do not know the proper procedure, or often don't take the formality seriously. It is a crime to lie to a public official, and a notary public, is an official position designated by the state where the notary resides or works.
