A Guide for Lawyers on Authenticating Social Media Evidence

Overview

Social media content is increasingly central to civil litigation, criminal proceedings, and regulatory matters, yet its admissibility depends on meeting authentication standards that courts scrutinize closely. This course walks legal professionals through the foundational steps for collecting social media evidence in a forensically sound manner, establishing and maintaining chain of custody, and presenting that evidence in a form courts will accept. It addresses the practical and procedural pitfalls that arise when social media posts, messages, profiles, and metadata are introduced as exhibits. Attorneys who understand these requirements are better positioned to protect the evidentiary record and challenge improperly authenticated evidence offered by opposing parties.
