What is eDiscovery
Electronic Discovery (eDiscovery) is the recovery of electronically stored information (ESI) for use in a legal matter.
eDiscovery can consist of e-mails, databases, cell phone records, calendars, text messages, office documents, etc.
A common practice in civil matters is for both plaintiff and defendant parties to negotiate what is, and isn't discoverable.
Recently the Federal Rules of Civil Procedure (FRCP) have been modified to codify various aspects of eDiscovery that has been practiced over the years.
Computer forensics is a specialized form of eDiscovery. Often the expectation with respect to eDiscovery is that all parties are producing the required materials, and aren't hiding or destroying information.
