As amended through December 28, 2023
Rule 1.6 - Confidentiality of Information
(a) A lawyer shall not reveal information relating to representation of a client unless the client consents after consultation, except for (1) disclosures that are impliedly authorized in order to carry out the representation, (2) disclosures of information that is generally known, and (3) as stated in paragraphs (b), (c) and (d).
(b) A lawyer shall reveal such information to the proper authorities, as soon as, and to the extent the lawyer reasonably believes necessary, to prevent the client or another person:
(1) from committing a criminal, illegal or fraudulent act that the lawyer reasonably believes is likely to result in death or substantial bodily harm or substantial injury to the financial interest or property of another; or
(2) from committing a criminal, illegal or fraudulent act that the lawyer reasonably believes is likely to perpetrate a fraud upon a tribunal.
(c) If a lawyer reveals information pursuant to RPC 1.6(b), the lawyer also may reveal the information to the person threatened to the extent the lawyer reasonably believes is necessary to protect that person from death, substantial bodily harm, substantial financial injury, or substantial property loss.
(d) A lawyer may reveal such information to the extent the lawyer reasonably believes necessary:
(1) to rectify the consequences of a client's criminal, illegal or fraudulent act in the furtherance of which the lawyer's services had been used;
(2) to establish a claim or defense on behalf of the lawyer in a controversy between the lawyer and the client, or to establish a defense to a criminal charge, civil claim or disciplinary complaint against the lawyer based upon the conduct in which the client was involved; or
(3) to prevent the client from causing death or substantial bodily harm to himself or herself;
(4) to comply with other law; or
(5) to detect and resolve conflicts of interest arising from the lawyer's change of employment or from changes in the composition or ownership, or resulting from the sale of a firm, but only if the revealed information would not compromise the attorney-client privilege or otherwise prejudice the client. Any information so disclosed may be used or further disclosed only to the extent necessary to detect and resolve conflicts of interest.
(e) Reasonable belief for purposes of RPC 1.6 is the belief or conclusion of a reasonable lawyer that is based upon information that has some foundation in fact and constitutes prima facie evidence of the matters referred to in subsections (b), (c), or (d).
(f) A lawyer shall make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client.

Official Comment (August 1, 2016)

Paragraph (d)(5) recognizes that lawyers in different firms may need to disclose limited information to each other to detect and resolve conflicts of interest, such as when a lawyer is considering an association with another firm, two or more firms are considering merger, or a lawyer is considering the purchase of a law practice. 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 such 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. Moreover, 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, paragraph (a) prohibits disclosure unless the client or former client gives informed written 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 pursuant to paragraph (d)(5) may be used or further disclosed only to the extent necessary to detect and resolve conflicts of interest. Paragraph (d)(5) does not restrict the use of information acquired by means independent of any disclosure pursuant to paragraph (d)(5). Paragraph (d)(5) also does not affect the disclosure of information within a law firm when the disclosure is otherwise authorized, such as 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.

Paragraph (f) requires a lawyer to act competently to safeguard information, including electronically stored 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 or entities who are participating in the representation of the client or who are subject to the lawyer's supervision. The unauthorized access to, or the inadvertent or unauthorized disclosure of, confidential information relating to the representation of a client does not constitute a violation of paragraph (f) 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 in writing 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, such as state and federal laws that govern data privacy or that impose notification requirements upon the loss of, or unauthorized access to, electronic information, is beyond the scope of these Rules.

Official Comment (September 1, 2018)

The Court adopts the comment in the Restatement (Third) of the Law Governing Lawyers on confidential information, which states:

Whether information is "generally known" depends on all circumstances relevant in obtaining the information. Information contained in books or records in public libraries, public-record depositaries such as government offices, or in publicly accessible electronic-data storage is generally known if the particular information is obtainable through publicly available indexes and similar methods of access. Information is not generally known when a person interested in knowing the information could obtain it only by means of special knowledge or substantial difficulty or expense. Special knowledge includes information about the whereabouts or identity of a person or other source from which the information can be acquired, if those facts are not themselves generally known.
