A legal hold (also known as a litigation hold) is a process used in eDiscovery to ensure that all relevant documents, data, and other information are preserved, so that they can be used in the event of a legal dispute or investigation. It is an obligation imposed on organizations to preserveall relevant data and information when litigation, an investigation, or an audit is reasonably anticipated. This helps to ensure that all information, regardless of where it is stored, is identified and preserved in an accessible form.
