Confidentiality
Rules limiting access to or distribution of certain information.
Last updated
Confidentiality refers to a set of rules or a promise—often formalized through confidentiality agreements—that restricts who can access certain information or how that information can be shared. In the legal field, lawyers are generally required by law to keep all matters related to a client’s representation confidential. This duty is broader than the attorney–client privilege, which only protects direct communications between them. Both rules exist to encourage clients to be open with their lawyers, allowing for a vigorous defense.
Without this protection, a client might hide a seemingly damaging fact that a skilled lawyer could use to their advantage, or the opposing side could spring a surprise in court. However, most jurisdictions allow lawyers to break confidentiality if they believe a client is about to kill or seriously harm someone, cause major financial or property damage, or use the lawyer’s services to commit a crime or fraud. In these cases, disclosure is usually discretionary, not mandatory. A few states, like New Jersey and Virginia, have made such disclosure mandatory.
Some jurisdictions also require the lawyer to first try persuading the client to follow the law before revealing anything. These exceptions generally do not cover past crimes, even extreme ones like murder. The U.S. Supreme Court and many state supreme courts have affirmed the right of a lawyer to withhold information in such situations, arguing that otherwise no criminal defendant could get a zealous defense.
California is known for having one of the strongest confidentiality duties; until a 2004 amendment, its lawyers could not even disclose that a client was about to commit murder. Recent UK laws have also limited confidentiality for professionals like accountants, who must now report suspicions of fraud or even legitimate tax-saving schemes if unknown to tax authorities. In English law, a breach of confidence requires three elements, as set out in the 1968 case Coco v A N Clark (Engineers) Ltd: the information must have a “quality of confidence,” it must have been shared in circumstances that create an obligation of confidence, and there must be an unauthorized use that harms the person who shared it. An 1896 case involving a doctor, William Smoult Playfair, highlighted the gap between lay and medical views on confidentiality.
Lore & Background
Confidentiality, in a legal context, is a set of rules or a promise, often formalized through agreements, that restricts access to or distribution of certain information. For lawyers, this duty is broader than the attorney–client evidentiary privilege, which only covers communications between them. The purpose is to encourage clients to speak frankly, allowing lawyers to provide zealous representation. However, most jurisdictions have exceptions: a lawyer may disclose information if they believe a client will kill or seriously injure someone, cause substantial financial harm, or use the lawyer’s services to commit a crime or fraud.
In most states, this disclosure is discretionary under Rule 1.6 of the Rules of Professional Conduct, but a few jurisdictions, such as New Jersey and Virginia, make it mandatory. Before disclosing, some jurisdictions require the lawyer to first try convincing the client to obey the law. These exceptions generally do not cover past crimes, even extreme ones like murder, as affirmed by the U.S. Supreme Court and many state supreme courts. California historically had one of the strongest duties, requiring lawyers to protect confidences at “every peril to himself,” not even permitting disclosure of imminent murder until a 2004 amendment.
In the UK, recent legislation now requires professionals like accountants to disclose suspicions of fraudulent accounting or legitimate tax saving schemes unknown to tax authorities. The English law of breach of confidence, established in the 1896 case of Dr. William Smoult Playfair, highlighted the difference between lay and medical views when a doctor informed his wife about a patient’s pregnancy, resulting in huge damages. Medical confidentiality, rooted in the Hippocratic Oath, has traditionally been a non-negotiable tenet, though in the United States, HIPAA and state laws include exceptions, such as reporting gunshot wounds or impaired drivers. In the European Union, inspectors under Directive 2001/20/EC must maintain confidentiality during good clinical practice inspections.
Reader's Guide
Confidentiality serves as a foundational principle in both legal and medical fields, promoting trust and open communication. In law, it enables zealous representation by encouraging clients to share all relevant facts, even those that might seem incriminating. In medicine, it protects patient privacy under laws like HIPAA and the Hippocratic Oath, though exceptions exist for reporting gunshot wounds or impaired drivers.
The balance between confidentiality and public safety remains contested, with jurisdictions varying on mandatory versus discretionary disclosure. The concept also extends to professional contexts like accounting, where UK law now requires disclosure of fraudulent accounting. Overall, confidentiality is a dynamic legal and ethical concept, shaped by statutory rules, professional codes, and court decisions.
Frequently Asked Questions
What is Confidentiality in legal terms?
Confidentiality is a set of rules or a binding promise that restricts who may access certain information and how it can be shared. It operates through confidentiality agreements and professional duties in legal, medical, and other specialized fields, with the exact scope and exceptions shifting depending on the jurisdiction.
Where does medical confidentiality come from?
The protection of doctor–patient conversations traces back to the Hippocratic Oath and is now codified in the physician-patient privilege recognized in many jurisdictions. It ensures that patients can speak openly with their providers without fear that their disclosures will surface in legal proceedings.
Why is Confidentiality considered a foundational legal concept?
It underpins trust in every professional relationship where sensitive information flows—lawyers, doctors, therapists, and corporate officers all rely on it to function. Without a predictable rule limiting disclosure, clients and patients would withhold the very information those professionals need to help them, collapsing the system.
