What is needed to authenticate a piece of evidence?

• A. A chain of custody alone
• B. A notarized certificate
• C. A public registry entry
• D. Evidence that the item is what it is claimed to be, typically via a witness with knowledge or other authentication

Answer: (D)

Authentication of evidence rests on proving the item is what it is claimed to be. The usual way to do this is through testimony or other proof from someone with knowledge about the item, showing that it is indeed what it is asserted to be. A witness who identifies the item, or proof that the item bears distinctive features, is a common path to authentication. Chain of custody matters for showing the item hasn’t been altered and supports reliability, but it doesn’t by itself prove the item’s true identity. Notarized certificates or public registry entries don’t automatically establish authenticity unless they specifically address what the item is, which is not required in most cases. So, the best answer is evidence that the item is what it is claimed to be, typically via a knowledgeable witness or other authentication.
