The question clearly beckons, should lawyers review metadata in documents? Is reviewing this data ethical, when the author of such data likely had no idea they were creating it? Metadata by its definition is simply, data about data. It can contain all sort of identifying information. One of the easiest ways for metadata to be left in a document is for the comments section to leave the comments feature turned on. Similarly, if you leave track changes turned on, the receiving attorney can not only read confidential comments that were meant to be intra-office or privileged communications between he attorney and client, but also the attorney can see what content was deleted from the document.
