A more thorough explanation: In legal terms, an affirmation is a solemn declaration made by a person who conscientiously declines to take an oath for religious or ethical reasons. It has the same legal effect as an oath and is used to affirm the truthfulness of a statement or testimony.
Example: The witness provided a sworn affirmation that the information given in the testimony was true and accurate.
