Key Differences
Affirm is often used in legal or solemn contexts where an individual declares something to be true without necessarily providing proof; on the other hand, attest is generally used when someone confirms or endorses the truth of something, usually involving some form of evidence or witness.
Affirmations can be personal and subjective, reflecting beliefs or feelings, whereas attestations are typically objective, focusing on factual verification.
In the context of documents, to affirm can mean to validate the document's content through a declaration, while to attest usually involves verifying the authenticity of the document or the accuracy of information presented.
When someone affirms, they often do so based on personal authority or belief; in contrast, attesting often involves an external validation, such as a witness or an expert opinion.
In legal terms, a sworn affirmation replaces an oath and serves the same purpose, while attesting is the act of witnessing the signing of a document and then signing it to confirm its authenticity.
