Metadata lurks in every electronic document, message or post each of us creates and edits - and in every platform, device and application we use. Whether or not they are litigators, all law department and law firm attorneys - and thus their clients - are susceptible to an inadvertent disclosure that could constitute a breach of confidentiality and perhaps even malpractice. Counsel can protect against such dangers by avoiding common but critical mistakes as to track changes, PDF conversions, redaction and electronic discovery.
