Rule 4-1.6 Confidentiality of Information

The lawyer is part of a judicial system charged with upholding the law. One of the lawyer’s functions is to advise clients so that they avoid any violation of the law in the proper exercise of their rights. 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 4-1.18 for the lawyer’s duties with respect to information provided to the lawyer by a prospective client, rule 4-1.9(c) for the lawyer’s duty not to reveal information relating to the lawyer’s prior representation of a former client, and rules 4-1.8(b) and 4-1.9(b) for the lawyer’s duties with respect to the use of confidential 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 terminology 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 on experience, lawyers know that almost all clients follow the advice given, and the law is upheld. The principle of confidentiality is given effect in 2 related bodies of law, the attorney-client privilege (which includes the work product doctrine) in the law of evidence and the rule of confidentiality established in professional ethics. The attorney- client privilege applies 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 applies not merely 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 confidential information except as authorized or required by the Rules Regulating The Florida Bar or by law. However, none of the foregoing limits the requirement of disclosure in subdivision (b). This disclosure is required to prevent a lawyer from becoming an unwitting accomplice in the fraudulent acts of a client. See also Scope. The requirement of maintaining confidentiality of information relating to representation applies to government lawyers who may disagree with the policy goals that their representation is designed to advance.

Authorized disclosure A lawyer is impliedly authorized to make disclosures about a client when appropriate in carrying out the representation, except to the extent that the client’s instructions or special circumstances limit that authority. In litigation, for example, a lawyer may disclose information by admitting a fact that cannot properly be disputed or in negotiation by making a disclosure that facilitates a satisfactory conclusion. 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 The confidentiality rule is subject to limited exceptions. In becoming privy to information about a client, a lawyer may foresee that the client intends serious harm to another person. However, to the extent a lawyer is required or permitted to disclose a client’s purposes, the client will be inhibited from revealing facts that would enable the lawyer to counsel against a wrongful course of action. While the public may be protected if full and open communication by the client is encouraged, several situations must be distinguished. First, the lawyer may not counsel or assist a client in conduct that is criminal or fraudulent. See rule 4-1.2(d). Similarly, a lawyer has a duty under rule 4-3.3(a)(4) not to use false evidence. This duty is essentially a special instance of the duty prescribed in rule 4-1.2(d) to avoid assisting a client in criminal or fraudulent conduct. Second, the lawyer may have been innocently involved in past conduct by the client that was criminal or fraudulent. In this situation the lawyer has not violated rule 4-1.2(d), because to “counsel or assist” criminal or fraudulent conduct requires knowing that the conduct is of that character. Third, the lawyer may learn that a client intends prospective conduct that is criminal. As stated in subdivision (b)(1), the lawyer must reveal information in order to prevent these consequences. It is admittedly difficult for a lawyer to “know” when the criminal intent will actually be carried out, for the client may have a change of mind. Subdivision (b)(2) contemplates past acts on the part of a client that may result in present or future consequences that may be avoided by disclosure of otherwise confidential communications. Rule 4-1.6(b)(2) would now require the lawyer to disclose information reasonably necessary to prevent the future death or substantial bodily harm to another, even though the act of the client has been completed. The lawyer’s exercise of discretion requires consideration of 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. Where practical the lawyer should seek to persuade the client to take suitable action. In any case, a disclosure adverse to the client’s interest should be no greater than the lawyer reasonably believes necessary to the purpose.

Withdrawal If 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 4-1.16(a)(1). After withdrawal the lawyer is required to refrain from making disclosure of the client’s confidences, except as otherwise provided in rule 4-1.6. Neither this rule nor rule 4-1.8(b) nor rule 4-1.16(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. Where the client is an organization, the lawyer may be in doubt whether contemplated conduct will actually be carried out by the organization. Where necessary to guide conduct in connection with the rule, the lawyer may make inquiry within the organization as indicated in rule 4-1.13(b).

Dispute concerning lawyer’s conduct 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. In most situations, disclosing information to secure this advice will be impliedly authorized for the lawyer to carry out the representation. Even when the disclosure is not impliedly authorized, subdivision (c)(5) permits this disclosure because of the importance of a lawyer’s compliance with the Rules of Professional 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. The lawyer’s right to respond arises when an assertion of complicity has been made. Subdivision (c) does not require the lawyer to await the commencement of an action or proceeding that charges complicity, so that the defense may be established by responding directly to a third party who has made the assertion. The right to defend, of course, applies where a proceeding has been commenced. Where practicable and not prejudicial to the lawyer’s ability to establish the defense, the lawyer should advise the client of the third party’s assertion and request that the client respond appropriately. In any event, disclosure should be no greater than the lawyer reasonably believes is necessary to vindicate innocence, 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. If the lawyer is charged with wrongdoing in which the client’s conduct is implicated, the rule of confidentiality should not prevent the lawyer from defending against the charge. A charge can arise in a civil, criminal, or professional disciplinary 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. A lawyer entitled to a fee is permitted by subdivision (c) 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. As stated above, the lawyer must make every effort practicable to avoid unnecessary disclosure of information relating to a representation, to limit disclosure to those having the need to know it, and to obtain protective orders or make other arrangements minimizing the risk of disclosure. Subdivision (c)(7) allows a lawyer to respond to specific allegations published via the internet by a former client (e.g. a negative online review) that the lawyer has engaged in criminal conduct punishable by law. However, under subdivision (f), even when the lawyer is operating within the scope of the (c)(7) exception, disclosure must be no greater than the lawyer reasonably believes necessary to refute the specific allegations.

Disclosures otherwise required or authorized The attorney-client privilege is differently defined in various jurisdictions. If a lawyer is called as a witness to give testimony concerning a client, absent waiver by the client, rule 4-1.6(a) requires the lawyer to invoke the privilege when it is applicable. The lawyer must comply with the final orders of a court or other tribunal of competent jurisdiction requiring the lawyer to give information about the client. The Rules of Professional Conduct in various circumstances permit or require a lawyer to disclose information relating to the representation. See rules 4-2.3, 4-3.3, and 4-4.1. In addition to these provisions, a lawyer may be obligated or permitted by other provisions of law to give information about a client. Whether another provision of law supersedes rule 4-1.6 is a matter of interpretation beyond the scope of these rules, but a presumption should exist against a supersession.

Detection of Conflicts of Interest Subdivision (c)(6) recognizes that lawyers in different firms may need to disclose limited information to each other to detect and resolve conflicts of interest, for example, when a lawyer is considering an association with another firm, two or more firms are considering a merger, or a lawyer is considering the purchase of a law practice. See comment to rule 4-1.17. Under these circumstances, lawyers and law firms are permitted to disclose limited information, but only once substantive discussions regarding the new relationship have occurred. Any disclosure should ordinarily include no more than the identity of the persons and entities involved in a matter, a brief summary of the general issues involved, and information about whether the matter has terminated. Even this limited information, however, should be disclosed only to the extent reasonably necessary to detect and resolve conflicts of interest that might arise from the possible new relationship. The disclosure of any information is prohibited if it would compromise the attorney-client privilege or otherwise prejudice the client (e.g., the fact that a corporate client is seeking advice on a corporate takeover that has not been publicly announced; that a person has consulted a lawyer about the possibility of divorce before the person’s intentions are known to the person’s spouse; or that a person has consulted a lawyer about a criminal investigation that has not led to a public charge). Under those circumstances, subdivision (a) prohibits disclosure unless the client or former client gives informed consent. A lawyer’s fiduciary duty to the lawyer’s firm may also govern a lawyer’s conduct when exploring an association with another firm and is beyond the scope of these rules. Any information disclosed under this subdivision may be used or further disclosed only to the extent necessary to detect and resolve conflicts of interest. This subdivision does not restrict the use of information acquired by means independent of any disclosure under this subdivision. This subdivision also does not affect the disclosure of information within a law firm when the disclosure is otherwise authorized, for example, when a lawyer in a firm discloses information to another lawyer in the same firm to detect and resolve conflicts of interest that could arise in connection with undertaking a new representation.

Acting Competently to Preserve Confidentiality Paragraph (e) requires a lawyer to act competently to safeguard information relating to the representation of a client against unauthorized access by third parties and 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 4-1.1, 4-5.1 and 4-5.3. For example, a lawyer should be aware that generative artificial Intelligence may create risks to the lawyer’s duty of confidentiality. The unauthorized access to, or the inadvertent or unauthorized disclosure of, information relating to the representation of a client does not constitute a violation of paragraph (e) if the lawyer has made reasonable efforts to prevent the access or disclosure. Factors to be considered in determining the reasonableness of the lawyer’s efforts include, but are not limited to, the sensitivity of the information, the likelihood of disclosure if additional safeguards are not employed, the cost of employing additional safeguards, the difficulty of implementing the safeguards, and the extent to which the safeguards adversely affect the lawyer’s ability to represent clients (e.g., by making a device or important piece of software excessively difficult to use). A client may require the lawyer to implement special security measures not required by this rule or may give informed consent to forgo security measures that would otherwise be required by this rule. Whether a lawyer may be required to take additional steps to safeguard a client’s information in order to comply with other law, for example state and federal laws that govern data privacy or that impose notification requirements on the loss of, or unauthorized access to, electronic information, is beyond the scope of these rules. For a lawyer’s duties when sharing information with nonlawyers outside the lawyer’s own firm, see the comment to rule 4-5.3. 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. Whether a lawyer may be required to take additional steps in order to comply with other law, for example state and federal laws that govern data privacy, is beyond the scope of these rules.

Former client The duty of confidentiality continues after the client-lawyer relationship has terminated. See rule 4-1.9 for the prohibition against using such information to the disadvantage of the former client.
