Affirmation Law and Legal Definition
Affirmation is a formal declaration of truth instead of making an oath. It is a declaration about something to be true. One who makes an affirmation or a positive declaration about something to be true is called an affirmant. For example, witnesses usually make affirmations about their testimony. If an affirmant willfully violates his affirmation, then the affirmant will be held liable for perjury.
