Attest vs. Certify: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Updated on November 29, 2023
Attest refers to bearing witness or confirming something is true based on personal knowledge or belief, while certify involves officially recognizing, guaranteeing, or declaring something as true, often in a formal or legal context.

Key Differences
Attest implies an assertion based on personal knowledge or experience, often used in legal or formal documents to confirm the truth of a statement. Certify, on the other hand, usually involves a higher level of authority or expertise, often requiring official or legal backing to confirm or endorse the validity of something.

In many legal scenarios, a witness may attest to the truth of a statement or event, meaning they declare their direct knowledge or belief about it. Certify usually involves a formal declaration by a qualified individual or entity, asserting the authenticity or accuracy of a document or fact.

Attest can also be used in contexts where someone supports or endorses a concept, idea, or quality based on their understanding or belief. Certify, however, often involves a process of verification or inspection, followed by issuing a certificate or official document to validate something.

When someone attests to something, they may not always have the official capacity or authority to provide legal proof. In contrast, to certify something usually requires the person or organization to have the necessary qualifications or legal power to issue a formal certification.

The act of attesting is often more personal or subjective, relying on an individual’s perception or experience. Conversely, certifying is typically objective, involving a set of standards or criteria that must be met for something to be certified.
