eDiscovery—the process of identifying, locating, and producing electronically stored information (ESI) in litigation—has become as central to legal practice as paper discovery once was. Understanding eDiscovery fundamentals is essential for any litigation team. The discovery process begins with a litigation hold notice, where parties must preserve all potentially relevant ESI. The identification phase involves determining what data exists across email, files, databases, and cloud storage. Litigation teams must locate ESI across custodians and systems, then filter and review for relevance and privilege before production. Key terminology includes: custodian (person or system with relevant data), ESI (any information stored electronically), metadata (embedded information about documents like creation date), chain of custody (documentation of evidence handling), and proportionality (balancing discovery burden against importance). Modern eDiscovery workflows leverage technology-assisted review (TAR/predictive coding) to identify relevant documents automatically, dramatically reducing manual review hours. Best practices include: establishing a litigation hold policy, identifying and interviewing custodians early, understanding your data landscape, using appropriate search terms and filters, maintaining privilege logs, and preserving metadata integrity. Common challenges include exponential data growth (typical cases involve 100,000-10M+ documents), high costs of manual review ($3,000-5,000 per attorney per 1,000 documents reviewed), and tight deadlines. The average eDiscovery project timeline spans 4-8 months from legal hold to production, with costs ranging from $50,000 for small cases to $500,000+ for enterprise litigation. Firms that master eDiscovery fundamentals reduce costs by 30-40%, accelerate case outcomes, and mitigate malpractice risk from improper data handling.
