End-of-life notice: American Legal Ethics Library
As of March 1, 2013, the Legal Information Institute is no longer maintaining the information in the American Legal Ethics Library. It is no longer possible for us to maintain it at a level of completeness and accuracy given its staffing needs. It is very possible that we will revive it at a future time. At this point, it is in need of a complete technological renovation and reworking of the "correspondent firm" model which successfully sustained it for many years.
Many people have contributed time and effort to the project over the years, and we would like to thank them. In particular, Roger Cramton and Peter Martin not only conceived ALEL but gave much of their own labor to it. We are also grateful to Brad Wendel for his editorial contributions, to Brian Toohey and all at Jones Day for their efforts, and to all of our correspondents and contributors. Thank you.
We regret any inconvenience.
Some portions of the collection may already be severely out of date, so please be cautious in your use of this material.
Maryland Lawyer's Rules of Professional Conduct
Comment - Rule 1.6
 This Rule governs the disclosure by a lawyer of information relating to the representation of a client during the lawyer’s representation of the client. See Rule 1.18 for the lawyer’s duties with respect to information provided to the lawyer by a prospective client, Rule 1.9(c)(2) for the lawyer’s duty not to reveal information relating to the lawyer’s prior representation of a former client and Rules 1.8(b) and 1.9(c)(1) for the lawyer’s duties with respect to the use of such information to the disadvantage of clients and former clients.
 A fundamental principle in the client-lawyer relationship is that, in the absence of the client’s informed consent, the lawyer must not reveal information relating to the representation. See Rule 1.0(f) for the definition of informed consent. This contributes to the trust that is the hallmark of the client-lawyer relationship. The client is thereby encouraged to seek legal assistance and to communicate fully and frankly with the lawyer even as to embarrassing or legally damaging subject matter. The lawyer needs this information to represent the client effectively and, if necessary, to advise the client to refrain from wrongful conduct. Almost without exception, clients come to lawyers in order to determine their rights and what is, in the complex of laws and regulations, deemed to be legal and correct. Based upon experience, lawyers know that almost all clients follow the advice given, and the law is upheld.
 The principle of client-lawyer confidentiality is given effect by related bodies of law: the attorney-client privilege, the work product doctrine and the rule of confidentiality established in professional ethics. The attorney-client privilege and work-product doctrine apply in judicial and other proceedings in which a lawyer may be called as a witness or otherwise required to produce evidence concerning a client. The rule of client-lawyer confidentiality applies in situations other than those where evidence is sought from the lawyer through compulsion of law. The confidentiality rule, for example, applies not only to matters communicated in confidence by the client but also to all information relating to the representation, whatever its source. A lawyer may not disclose such information except as authorized or required by the Maryland Lawyers’ Rules of Professional Conduct or other law. See also Scope.
 Paragraph (a) prohibits a lawyer from revealing information relating to the representation of a client. This prohibition also applies to disclosures by a lawyer that do not in themselves reveal protected information but could reasonably lead to the discovery of such information by a third person. A lawyer’s use of a hypothetical to discuss issues relating to the representation is permissible so long as there is no reasonable likelihood that the listener will be able to ascertain the identity of the client or the situation involved.
Implied Authority to Disclose
 Except to the extent that the client’s instructions or special circumstances limit that authority, a lawyer is impliedly authorized to make disclosures about a client when appropriate in carrying out the representation. In some situations, for example, a lawyer may be impliedly authorized to admit a fact that cannot properly be disputed, or to make a disclosure that facilitates a satisfactory conclusion to a matter. Lawyers in a firm may, in the course of the firm’s practice, disclose to each other information relating to a client of the firm, unless the client has instructed that particular information be confined to specified lawyers.
Disclosure Adverse to Client
 Although the public interest is usually best served by a strict rule requiring lawyers to preserve the confidentiality of information relating to the representation of their clients, the confidentiality rule is subject to limited exceptions. Paragraph (b), however, permits disclosure only to the extent the lawyer reasonably believes the disclosure is necessary to accomplish one of the purposes specified. Where practicable, the lawyer should first seek to persuade the client to take suitable action to obviate the need for disclosure. In any case, a disclosure adverse to the client’s interest should be no greater than the lawyer reasonably believes necessary to accomplish the purpose. If the disclosure will be made in connection with a judicial proceeding, the disclosure should be made in a manner that limits access to the information to the tribunal or other persons having a need to know it and appropriate protective orders or other arrangements should be sought by the lawyer to the fullest extent practicable.
 Paragraph (b) permits, but does not require the disclosure of information relating to a client’s representation to accomplish the purposes specified in paragraphs (b)(1) through (b)(6). In exercising the discretion conferred by this Rule, the lawyer may consider such factors as the nature of the lawyer’s relationship with the client and with those who might be injured by the client, the lawyer’s own involvement in the transaction and factors that may extenuate the conduct in question. A lawyer’s decision not to disclose as permitted by paragraph (b) does not violate this Rule. Disclosure may be required, however, by other Rules regardless of whether the disclosure is permitted by Rule 1.6. See Rules 1.2(d), 3.3(a)(4), 4.1(b), 8.1 and 8.3. A lawyer representing an organization may in some circumstances be permitted to disclose information regardless of whether the disclosure is permitted by Rule 1.6(b). See Rule 1.13(c).
 Paragraph (b)(1) recognizes the overriding value of life and physical integrity and permits disclosure reasonably believed necessary to prevent reasonably certain death or substantial bodily harm. Such harm is reasonably certain to occur if it will be suffered imminently 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 take action necessary to eliminate the threat. Thus, a lawyer who knows that a client has accidentally discharged toxic waste into a town’s water supply may reveal this information to the authorities if there is a present and substantial risk that a person who drinks the water will contract a life-threatening or debilitating disease, and the lawyer reasonably believes disclosure is necessary to eliminate the threat or reduce the number of victims.
 Paragraph (b)(2) is a limited exception to the rule of confidentiality that permits the lawyer to reveal information to the extent necessary to enable affected persons or appropriate authorities to prevent the client from committing a crime or a fraud, as defined in Rule 1.0(e), that is reasonably certain to result in substantial injury to the financial or property interests of another and in furtherance of which the client has used or is using the lawyer’s services. Such a serious abuse of the client-lawyer relationship by the client forfeits the protection of this Rule. The client can, of course, prevent such disclosure by refraining from the wrongful conduct. Although paragraph (b)(2) does not require the lawyer to reveal the client’s misconduct, the lawyer may not counsel or assist the client in conduct the lawyer knows is criminal or fraudulent. See Rule 1.2(d). See also Rule 1.16 with respect to the lawyer’s obligation or right to withdraw from the representation of the client in such circumstances. Where the client is an organization, the lawyer should consult Rule 1.13(b).
 Paragraph (b)(3) addresses the situation in which the lawyer does not learn of a client’s criminal or fraudulent act in furtherance of which the lawyer’s services were used until after the act has occurred. Although the client no longer has the option of preventing disclosure by refraining from the wrongful conduct, there will be situations in which the loss suffered by the affected person can be prevented, rectified or mitigated. In such situations, the lawyer may disclose information relating to the representation to the extent necessary to enable the affected persons to prevent or mitigate reasonably certain losses or to attempt to recoup their losses. Paragraph (b)(3) does not apply when a person who has committed a crime or fraud thereafter employs a lawyer for representation concerning that offense.
 A lawyer’s confidentiality obligations do not preclude a lawyer from securing confidential legal advice about the lawyer’s personal responsibility to comply with these Rules, a court order or other law. In most situations, disclosing information to secure such advice will be impliedly authorized for the lawyer to carry out the representation. Even when the disclosure is not impliedly authorized, paragraph (b)(4) permits such disclosure because of the importance of a lawyer’s compliance with the law.
 If the lawyer knows that the lawyer’s services will be used by the client in materially furthering a course of criminal or fraudulent conduct, the lawyer must withdraw, as stated in Rule 1.16 (a)(1). After withdrawal the lawyer is required to refrain from making disclosure of the client’s confidences, except as otherwise provided in Rule 1.6 or in other Rules.
 If the lawyer knows that despite the withdrawal the client is continuing in conduct that is criminal or fraudulent, and is making use of the fact that the lawyer was involved in the matter, the lawyer may have to take positive steps to avoid being held to have assisted the conduct. See Rules 1.2(d) and 4.1(b). In other situations not involving such assistance, the lawyer has discretion to make disclosure of otherwise confidential information only in accordance with Rules 1.6 and 1.13(c). Neither this Rule nor Rule 1.8(b) nor Rule 1.16(d) prevents the lawyer from giving notice of the fact of withdrawal, and the lawyer may also withdraw or disaffirm any opinion, document, affirmation, or the like.
Dispute Concerning Lawyer's Conduct
 Where a legal claim or disciplinary charge alleges complicity of the lawyer in a client’s conduct or other misconduct of the lawyer involving representation of the client, the lawyer may respond to the extent the lawyer reasonably believes necessary to establish a defense. The same is true with respect to a claim involving the conduct or representation of a former client. Such a charge can arise in a civil, criminal, disciplinary or other proceeding and can be based on a wrong allegedly committed by the lawyer against the client or on a wrong alleged by a third person, for example, a person claiming to have been defrauded by the lawyer and client acting together. The lawyer’s right to respond arises when an assertion of such complicity has been made. Paragraph (b)(5) does not require the lawyer to await the commencement of an action or proceeding that charges such complicity, so that the defense may be established by responding directly to a third party who has made such an assertion. The right to defend also applies, of course, where a proceeding has been commenced.
 A lawyer entitled to a fee is permitted by paragraph (b)(5) to prove the services rendered in an action to collect it. This aspect of the rule expresses the principle that the beneficiary of a fiduciary relationship may not exploit it to the detriment of the fiduciary.
Disclosures Otherwise Required or Authorized
 As noted in Comment 7, Rules 3.3(b) and 4.1(b) require disclosure in some circumstances regardless of whether the disclosure is permitted by Rule 1.6. Circumstances may be such that disclosure is required under other Rules, for example, Rule 1.2(d), in order to avoid assisting a client to perpetrate a crime or fraud.
 Other law may require that a lawyer disclose information about a client. Whether such a law supersedes Rule 1.6 is a question of law beyond the scope of these Rules. When disclosure of information relating to the representation appears to be required by other law, the lawyer must discuss the matter with the client to the extent required by Rule 1.4. If, however, the other law supersedes this Rule and requires disclosure, paragraph (b)(6) permits the lawyer to make such disclosures as are necessary to comply with the law.
 A lawyer may be ordered to reveal information relating to the representation of a client by a court or by another tribunal or governmental entity claiming authority pursuant to other law to compel the disclosure. Absent informed consent of the client to do otherwise, the lawyer should assert on behalf of the client all nonfrivolous claims that the order is not authorized by other law or that the information sought is protected against disclosure by the attorney-client privilege or other applicable law. In the event of an adverse ruling, the lawyer must consult with the client about the possibility of appeal to the extent required by Rule 1.4. Unless review is sought, however, paragraph (b)(6) permits the lawyer to comply with the court’s order.
Acting Competently to Preserve Confidentiality
 A lawyer must act competently to safeguard information relating to the representation of a client against inadvertent or unauthorized disclosure by the lawyer or other persons who are participating in the representation of the client or who are subject to the lawyer’s supervision. See Rules 1.1, 5.1 and 5.3.
 When transmitting a communication that includes information relating to the representation of a client, the lawyer must take reasonable precautions to prevent the information from coming into the hands of unintended recipients. This duty, however, does not require that the lawyer use special security measures if the method of communication affords a reasonable expectation of privacy. Special circumstances, however, may warrant special precautions. Factors to be considered in determining the reasonableness of the lawyer’s expectation of confidentiality include the sensitivity of the information and the extent to which the privacy of the communication is protected by law or by a confidentiality agreement. A client may require the lawyer to implement special security measures not required by this Rule or may give informed consent to the use of a means of communication that would otherwise be prohibited by this Rule.
 The duty of confidentiality continues after the client-lawyer relationship has terminated. See Rule 1.9(c)(2). See Rule 1.9(c)(1) for the prohibition against using such information to the disadvantage of the former client.
Model Rules Comparison
Rule 1.6 retains elements of former Rule 1.6 language, incorporates some changes from the Ethics 2000 Amendments to the ABA Model Rules, and incorporates further revisions.
