MPRE Confidentiality Rules: The Core Duty Under Model Rule 1.6
Under the ABA Model Rule 1.6, the scope of protected information is expansive. It is not limited to secrets or "confidences" shared by the client; rather, it includes all information relating to the representation, whether it was acquired before, during, or after the professional relationship. This means that if a lawyer learns about a client’s business dealings through a third party or observes a client’s physical condition during a meeting, that information is protected. On the MPRE, a common distractor involves suggesting that information in the "public record" is not confidential. This is false. Even if a fact is technically public, a lawyer may not disclose it if it relates to the case, unless the information has become "generally known" in the community or industry—a much higher threshold than being merely discoverable in public files. The duty applies to all forms of communication, including oral, written, and electronic data, and covers even the identity of the client if revealing it would be detrimental to the client's interests.
Duration of the Confidentiality Duty
The obligation of attorney client confidentiality is perpetual. It does not terminate when the legal matter concludes, nor does it end when the lawyer-client relationship is formally severed. Most importantly for MPRE purposes, the duty survives the death of the client. Exam questions often present scenarios where a former client has passed away and a third party, such as an executor or a family member, seeks information. Unless a specific exception applies or the client provided informed consent prior to death, the lawyer must maintain silence. The rationale is to encourage full and frank communication; clients would be less likely to share sensitive details if they feared their secrets would be revealed after they were no longer around to protect their own interests. This survival of the duty contrasts sharply with many other contractual obligations, reinforcing the fiduciary nature of the legal profession.
Permissive Disclosures to Prevent Physical Harm
The 'Reasonably Certain' Standard for Death or Bodily Harm
One of the most critical exceptions to confidentiality involves the prevention of physical injury. Under Rule 1.6(b)(1), a lawyer may reveal confidential information to the extent the lawyer reasonably believes necessary to prevent future harm prevention in the form of "reasonably certain death or substantial bodily harm." The "reasonably certain" standard is a high bar. It applies if the harm is imminent or if there is a present and substantial threat that a person will suffer such harm at a later date if the lawyer fails to act. For example, if a client informs their lawyer that they have disposed of toxic waste in a way that creates a significant risk of contaminating a public water supply, the lawyer may disclose this information even if the illness or death might not occur for years. Note that the lawyer’s belief must be "reasonable"—meaning a prudent and competent lawyer would agree that disclosure is necessary to prevent the outcome.
Discretion and Scope of Permitted Revelation
It is vital for MPRE candidates to recognize that Rule 1.6(b)(1) is permissive, not mandatory. The rule states a lawyer may reveal, not must reveal. While a lawyer may face moral pressure to act, they generally do not violate the Model Rules by remaining silent in the face of threatened physical harm, unless another rule (such as the duty to the tribunal) intervenes. If a lawyer chooses to disclose, the "extent reasonably necessary" limitation applies. The lawyer must only reveal the minimum amount of information required to prevent the harm. For instance, if a client threatens to kill a witness, the lawyer should notify the authorities or the witness but should not disclose unrelated prior crimes the client committed. Over-disclosure is a disciplinary violation, even when a valid exception exists. Scoring on the MPRE often hinges on identifying whether the lawyer’s disclosure was narrowly tailored to the specific emergency at hand.
Disclosures for Financial Harm and the Crime-Fraud Exception
Preventing or Rectifying Financial Injury
The MPRE frequently tests the crime-fraud exception as it relates to financial interests. Under Rule 1.6(b)(2) and (3), a lawyer may disclose information to prevent a client from committing a crime or fraud that is reasonably certain to result in substantial injury to the financial interests or property of another. This exception specifically applies when the client has used—or is currently using—the lawyer's services to further that crime or fraud. If the client has already completed the act, Rule 1.6(b)(3) allows for disclosure to prevent, mitigate, or rectify the substantial financial injury. This is a crucial distinction from the physical harm exception: for financial harm, the lawyer's services must be "baked into" the misconduct. If a client commits a fraud entirely independent of the lawyer's work, the lawyer has no permissive right to disclose that past fraud under this specific subsection.
Client Use of Lawyer's Services in a Crime or Fraud
The duty to disclose client crime in the context of financial harm is a misnomer; like the physical harm exception, this is almost always permissive under Rule 1.6. The "services" requirement means the lawyer's work—such as drafting a contract, filing a disclosure statement, or issuing an opinion letter—was the vehicle through which the fraud was perpetrated. If the lawyer discovers that their work product is being used to swindle investors, they may break confidentiality to stop the scheme or help the victims recover their losses. On the MPRE, watch for scenarios where the client confesses to a past financial crime that did not involve the lawyer. In such cases, the exception does not apply, and the lawyer must remain silent. The policy here is to prevent lawyers from being used as "unwitting agents" of dishonesty, while still protecting the sanctity of the client's past secrets where the lawyer's hands are clean.
Disclosures for Self-Protection and Fee Collection
Asserting a Claim or Defense Against a Client
Rule 1.6(b)(5) provides a "self-defense" exception to the confidentiality rules. A lawyer may reveal confidential information to the extent necessary to establish a claim or defense in a controversy between the lawyer and the client. The most common application is a fee dispute. If a lawyer sues a client for unpaid legal fees, the lawyer may disclose confidential information about the work performed to justify the bill. This is an essential protection for the practitioner, ensuring that the duty of confidentiality is not used as a sword by the client to avoid legitimate financial obligations. However, the disclosure must still be limited; the lawyer cannot reveal embarrassing or damaging information about the client that is irrelevant to the fee collection. The MPRE often tests this by presenting a lawyer who reveals a client's unrelated criminal history during a fee hearing—this would be a violation of the rules.
Responding to Ethics Complaints or Malpractice Claims
The self-defense exception also applies when a lawyer must respond to allegations in any proceeding concerning the lawyer's representation of the client. This includes defending against a legal malpractice lawsuit or responding to a formal disciplinary investigation by the state bar. A lawyer does not have to wait for the commencement of a formal lawsuit to disclose; they may do so when a "charge" has been made, such as a client filing a grievance. The rule allows the lawyer to "set the record straight." For example, if a client accuses a lawyer of missing a filing deadline, the lawyer may reveal confidential communications showing the client explicitly instructed them not to file. The key for the MPRE is that the disclosure must be "defensive"—it cannot be used as a preemptive strike or as a tool for retaliation against a difficult client.
Confidentiality Conflicts with Other Duties
When Candor to the Tribunal (Rule 3.3) Trumps Confidentiality
While Rule 1.6 is primarily permissive, it is often overridden by Model Rule 3.3, which governs Candor to the Tribunal. This is one of the few instances where a lawyer has a mandatory duty to disclose client crime or fraud. If a lawyer, the lawyer’s client, or a witness called by the lawyer has offered material evidence and the lawyer comes to know of its falsity, the lawyer must take reasonable remedial measures. These measures include, if necessary, disclosure to the court. Rule 3.3(c) explicitly states that the duties of candor apply even if compliance requires disclosure of information otherwise protected by Rule 1.6. On the MPRE, this creates a hierarchy: the duty to prevent a fraud on the court is superior to the duty of confidentiality. If a client commits perjury, the lawyer must first attempt to persuade the client to correct it; if that fails, the lawyer may seek to withdraw; if withdrawal is not possible or will not remedy the situation, the lawyer must inform the judge.
Balancing Confidentiality with the Duty to Report Misconduct (Rule 8.3)
Another point of tension occurs under Rule 8.3, which requires a lawyer to report the professional misconduct of another lawyer. However, Rule 8.3(c) contains a critical limitation: it does not require the disclosure of information otherwise protected by Rule 1.6. This means that if a lawyer learns of another attorney's embezzlement while representing that attorney as a client, the duty of confidentiality prevails over the duty to report. The MPRE frequently tests this specific intersection. Candidates must remember that the "snitch rule" is subordinate to the confidentiality rule. A lawyer cannot be disciplined for failing to report a colleague if the knowledge of the colleague's misconduct is "information relating to the representation" of a client. This protects the integrity of the legal consultation process, even when the client is themselves a member of the bar.
Confidentiality in Specific Practice Contexts
Confidentiality and Corporate Clients
When representing an organization, the "client" is the entity itself, not the individual officers or employees. Therefore, the duty of confidentiality is owed to the corporation. Under Rule 1.13, if a lawyer for an organization knows that an officer is engaged in action that is a violation of a legal obligation to the organization, and that action is likely to result in substantial injury to the organization, the lawyer must "report up" to higher authority, such as the Board of Directors. If the highest authority fails to act, the lawyer may "report out" (disclose confidential information) only if and to the extent the lawyer reasonably believes necessary to prevent substantial injury to the organization. This "reporting out" is an extension of the Rule 1.6 exceptions, specifically tailored to the corporate environment. The MPRE often tests whether a lawyer wrongly disclosed information to the SEC or the public before exhausting internal remedies within the company.
Confidentiality in Joint Representations
In a joint representation (e.g., representing two co-defendants or a husband and wife in estate planning), the duty of confidentiality is complex. Generally, there are no "secrets" between the joint clients regarding the matter for which they are jointly represented. If one client shares information with the lawyer that is relevant to the other client's interests, the lawyer typically has a duty to share that information with the co-client. However, the lawyer should clarify this arrangement at the outset of the representation. If a conflict arises where one client demands secrecy, the lawyer may be forced to withdraw from representing both clients, as the duty of loyalty to one (requiring disclosure) clashes with the duty of confidentiality to the other (requiring silence). MPRE questions on this topic usually focus on the lawyer's failure to maintain a balance, or the lawyer's improper disclosure to one client of a secret that the other client clearly intended to keep private.
Modern legal practice introduces the duty of competence in technology. Rule 1.6(c) requires a lawyer to make "reasonable efforts" to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation. This is not a "strict liability" rule; a lawyer is not necessarily disciplined every time a data breach occurs. Instead, the MPRE assesses whether the lawyer took reasonable precautions based on the sensitivity of the data, the cost of safeguards, and the difficulty of implementing them. Using unencrypted email is generally considered acceptable for routine matters, but highly sensitive trade secrets might require more robust security. Additionally, the "inadvertent disclosure" rule (Rule 4.4(b)) dictates that if a lawyer receives a document relating to the representation of their client and knows it was sent by mistake, they must promptly notify the sender. This intersects with confidentiality by requiring the receiving lawyer to respect the possible breach of the opponent's confidential information.
