MBE Evidence: Authentication

An overview of authentication principles and rules as set forth in the Evidence section of the MBE.

Overview

Authentication is a foundational requirement in the law of evidence, ensuring that evidence presented in court is genuine and reliable. Under the Federal Rules of Evidence, a party must authenticate evidence before it can be admitted, establishing that the item is what it claims to be. This is crucial not only for documents and photographs but extends to digital evidence and other forms of media as well.

The burden of production for authentication typically rests with the proponent of the evidence. Various methods of authentication exist, including testimony by a witness that the item is what it purports to be, distinctive characteristics of the evidence, and introducing an admission or stipulation from the opposing party regarding authenticity. With the rise of technology, practitioners must also navigate the authentication of electronic evidence, which includes emails, social media posts, and digital files, further complicating the authentication endeavor on the MBE.
