Today, the ABA Journal published more helpful information: Redacting confidential client information: The devil is in the details. The post points out the risks in failing to understand how property to redact a document. I recommend it.
One risk? Disciplinary action. Lawyers have a duty not to disclose information relating to the representation of a client. There’s also a duty to use reasonable safeguards to protect against unauthorized access to or inadvertent disclosure of confidential information. In my view, employing a redaction method that fails to keep information confidential is not a reasonable safeguard.
Rather, it’s tech incompetence.
