ABA Formal Opinion 477R
ABA Formal Opinion 477R is an ethics opinion issued by the American Bar Association’s Standing Committee on Ethics and Professional Responsibility. It addresses a lawyer’s duty to protect the confidentiality of client information when communicating over the internet, and concludes that lawyers must use reasonable efforts to prevent unauthorized access to that information.
What the Opinion Says
Opinion 477R updates earlier guidance for a world of pervasive cyber threats. It states that, while unencrypted email is often permissible for routine communication, a lawyer must assess the sensitivity of the information and the risk involved, and may be required to use stronger safeguards — such as encryption or secure portals — for particularly sensitive matters. It calls for a fact-based, case-by-case judgment.
The Underlying Ethical Duties
The opinion flows from the ABA Model Rules of Professional Conduct — the duty of competence, which has been read to include technological competence, and the duty of confidentiality, which requires reasonable efforts to prevent unauthorized disclosure of client information. Opinion 477R applies those duties specifically to electronic communication and law firm cybersecurity.
