Tex. R. Disc. Prof'l. Cond. 1.05

As amended through June 28, 2024
Rule 1.05 - Confidentiality of Information
(a) Confidential information includes both privileged information and unprivileged client information. Privileged information refers to the information of a client protected by the lawyer-client privilege of Rule 5.03 of the Texas Rules of Evidence or of Rule 5.03 of the Texas Rules of Criminal Evidence or by the principles of attorney-client privilege governed by Rule 5.01 of the Federal Rules of Evidence for United States Courts and Magistrates. Unprivileged client information means all information relating to a client or furnished by the client, other than privileged information, acquired by the lawyer during the course of or by reason of the representation of the client.
(b) Except as permitted by paragraphs (c) and (d), or as required by paragraphs (e), and (f), a lawyer shall not knowingly:
1) Reveal confidential information of a client or a former client to:
(i) a person that the client has instructed is not to receive the information; or
(ii) anyone else, other than the client, the client's representatives, or the members, associates, or employees of the lawyer's law firm.
2) Use confidential information of a client to the disadvantage of the client unless the client consents after consultations.
(3) Use confidential information of a former client to the disadvantage of the former client after the representation is concluded unless the former client consents after consultation or the confidential information has become generally known.
(4) Use privileged information of a client for the advantage of the lawyer or of a third person, unless the client consents after consultation.
(c) A lawyer may reveal confidential information:
(1) When the lawyer has been expressly authorized to do so in order to carry out the representation.
(2) When the client consents after consultation.
(3) To the client, the client's representatives, or the members, associates, and employees of the lawyers firm, except when otherwise instructed by the client.
(4) When the lawyer has reason to believe it is necessary to do so in order to comply with a court order, a Texas Disciplinary Rule of Professional Conduct, or other law.
(5) To the extent reasonably necessary to enforce a claim or establish a defense on behalf of the lawyer in a controversy between the lawyer and the client.
(6) To establish a defense to a criminal charge, civil claim or disciplinary complaint against the lawyer or the lawyer's associates based upon conduct involving the client or the representation of the client.
(7) When the lawyer has reason to believe it is necessary to do so in order to prevent the client from committing a criminal or fraudulent act.
(8) To the extent revelation reasonably appears necessary to rectify the consequences of a client's criminal or fraudulent act in the commission of which the lawyer's services had been used.
(9) To secure legal advice about the lawyer's compliance with these Rules.
(10) When the lawyer has reason to believe it is necessary to do so in order to prevent the client from dying by suicide.
(d) A lawyer also may reveal unprivileged client information.
(1) When impliedly authorized to do so in order to carry out the representation.
(2) When the lawyer has reason to believe it is necessary to do so in order to:
(i) carry out the representation effectively;
(ii) defend the lawyer or the lawyer's employees or associates against a claim of wrongful conduct;
(iii) respond to allegations in any proceeding concerning the lawyers representation of the client; or
(iv) prove the services rendered to a client, or the reasonable value thereof, or both, in an action against another person or organization responsible for the payment of the fee for services rendered to the client.
(e) When a lawyer has confidential information clearly establishing that a client is likely to commit a criminal or fraudulent act that is likely to result in death or substantial bodily harm to a person, the lawyer shall reveal confidential information to the extent revelation reasonably appears necessary to prevent the client from committing the criminal or fraudulent act.
(f) A lawyer shall reveal confidential information when required to do so by Rule 3.03(a)(2), 3.03(b), or by Rule 4.01(b).

Amended May 25, 2021, effective 7/1/2021.


Confidentiality Generally

1. Both the fiduciary relationship existing between lawyer and client and the proper functioning of the legal system require the preservation by the lawyer of confidential information of one who has employed or sought to employ the lawyer. Free discussion should prevail between lawyer and client in order for the lawyer to be fully informed and for the client to obtain the full benefit of the legal system. The ethical obligation of the lawyer to protect the confidential information of the client not only facilitates the proper representation of the client but also encourages potential clients to seek early legal assistance.

2. Subject to the mandatory disclosure requirements of paragraphs (e) and (f) the lawyer generally should be required to maintain confidentiality of information acquired by the lawyer during the course of or by reason of the representation of the client. This principle involves an ethical obligation not to use the information to the detriment of the client or for the benefit of the lawyer or a third person. In regard to an evaluation of a matter affecting a client for use by a third person, see Rule 2.02.

3. The principle of confidentiality is given effect not only in the Texas Disciplinary Rules of Professional Conduct but also in the law of evidence regarding the attorney-client privilege and in the law of agency. The attorney-client privilege, developed through many decades, provides the client a right to prevent certain confidential communications from being revealed by compulsion of law. Several sound exceptions to confidentiality have been developed in the evidence law of privilege. Exceptions exist in evidence law where the services of the lawyer were sought or used by a client in planning or committing a crime or fraud as well as where issues have arisen as to breach of duty by the lawyer or by the client to the other.

4. Rule 1.05 reinforces the principles of evidence law relating to the attorney-client privilege. Rule 1.05 also furnishes considerable protection to other information falling outside the scope of the privilege Rule 1.05 extends ethical protection generally to unprivileged information relating to the client or furnished by the client during the course of or by reason of the representation of the client. In this respect Rule 1.05 accords with general fiduciary principles of agency.

5. The requirement of confidentiality applies to government lawyers who may disagree with the policy goals that their representation is designed to advance.

Disclosure for Benefit of Client

6. A lawyer may be expressly authorized to make disclosures to carry out the representation and generally is recognized as having implied-in-fact authority to make disclosures about a client when appropriate in carrying out the representation to the extent that the client's instructions do not 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. The effect of Rule 1.05 is to require the lawyer to invoke, for the client, the attorney-client privilege when applicable; but if the court improperly denies the privilege, under paragraph (c)(4) the lawyer may testify as ordered by the court or may test the ruling as permitted by Rule 3.04(d).

7. In the course of a firms practice, lawyers may disclose to each other and to appropriate employee's information relating to a client, unless the client has instructed that particular information be confined to specified lawyers. Sub-paragraphs (b)(1) and (c)(3) continue these practices concerning disclosure of confidential information within the firm.

Use of Information

8. Following sound principles of agency law, sub-paragraphs (b)(2) and (4) subject a lawyer to discipline for using information relating to the representation in a manner disadvantageous to the client or beneficial to the lawyer or a third person, absent the informed consent of the client. The duty not to misuse client information continues after the client-lawyer relationship has terminated. Therefore, the lawyer is forbidden by sub-paragraph (b)(3) to use, in absence of the client's informed consent, confidential information of the former client to the client's disadvantage, unless the information is generally known.

Discretionary Disclosure Adverse to Client

9. In becoming privy to information about a client, a lawyer may foresee that the client intends serious and perhaps irreparable harm. To the extent a lawyer is prohibited from making disclosure, the interests of the potential victim are sacrificed in favor of preserving the client's information-usually unprivileged information-even though the client's purpose is wrongful. On the other hand, a client who knows or believes that a lawyer is required or permitted to disclose a client's wrongful purposes may be inhibited from revealing facts which would enable the lawyer to counsel effectively against wrongful action. Rule 1.05 thus involves balancing the interests of one group of potential victims against those of another. The criteria provided by the Rule are discussed below.

10. Rule 5.03(d)(1) Texas Rules of Civil Evidence (Tex. R. Civ. Evid.), and Rule 5.03(d)(1), Texas Rules of Criminal Evidence (Tex R. Crim. Evid.), indicate the underlying public policy of furnishing no protection to client information where the client seeks or uses the services of the lawyer to aid in the commission of a crime or fraud. That public policy governs the dictates of Rule 1.05. Where the client is planning or engaging in criminal or fraudulent conduct or where the culpability of the lawyers conduct is involved, full protection of client information is not justified.

11. Several other situations must be distinguished. First, the lawyer may not counsel or assist a client in conduct that is criminal or fraudulent. See Rule 1.02(c). As noted in the Comment to that Rule there can be situations where the lawyer may have to reveal information relating to the representation in order to avoid assisting a client's criminal or fraudulent conduct, and sub-paragraph (c)(4) permits doing so. A lawyer's duty under Rule 3.03(a) not to use false or fabricated evidence is a special instance of the duty prescribed in Rule 1.02(c) to avoid assisting a client in criminal or fraudulent conduct, and sub-paragraph (c)(4) permits revealing information necessary to comply with Rule 3.03(a) or (b). The same is true of compliance with Rule 4.01. See also paragraph (f).

12. Second, the lawyer may have been innocently involved in past conduct by the client that was criminal or fraudulent. In such a situation the lawyer has not violated Rule 1.02(c), because to counsel or assist criminal or fraudulent conduct requires knowing that the conduct is of that character. Since the lawyer's services were made an instrument of the client's crime or fraud, the lawyer has a legitimate interest both in rectifying the consequences of such conduct and in avoiding charges that the lawyer's participation was culpable. Sub-paragraph (c)(6) and (8) give the lawyer professional discretion to reveal both unprivileged and privileged information in order to serve those interests. See paragraph (g). In view of Tex. R. Civ. Evid. Rule 5.03(d)(1), and Tex. R. Crim. Evid. 5.03(d)(1), however, rarely will such information be privileged.

13. Third, the lawyer may learn that a client intends prospective conduct that is criminal or fraudulent. The lawyer's knowledge of the client's purpose may enable the lawyer to prevent commission of the prospective crime or fraud. When the threatened injury is grave, the lawyer's interest in preventing the harm may be more compelling than the interest in preserving confidentiality of information. As stated in sub-paragraph (c)(7), the lawyer has professional discretion, based on reasonable appearances, to reveal both privileged and unprivileged information in order to prevent the client's commission of any criminal or fraudulent act. In some situations of this sort, disclosure is mandatory. See paragraph (e) and Comments 18-20.

14. The lawyers exercise of discretion under paragraphs (c) and (d) involves consideration of such factors as the magnitude, proximity, and likelihood of the contemplated wrong, 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 client's conduct in question. In any case a disclosure adverse to the client's interest should be no greater than the lawyer believes necessary to the purpose. Although preventive action is permitted by paragraphs (c) and (d), failure to take preventive action does not violate those paragraphs. But see paragraphs (e) and (f). Because these rules do not define standards of civil liability of lawyers for professional conduct, paragraphs (c) and (d) do not create a duty on the lawyer to make any disclosure and no civil liability is intended to arise from the failure to make such disclosure.

15. A lawyer entitled to a fee necessarily must be permitted to prove the services rendered in an action to collect it, and this necessity is recognized by sub-paragraphs (c)(5) and (d)(2)(iv). This aspect of the rule, in regard to privileged information, expresses the principle that the beneficiary of a fiduciary relationship may not exploit the relationship to the detriment of the fiduciary. Any disclosure by the lawyer, however, should be as protective of the client's interests as possible.

16. If the client is an organization, a lawyer also should refer to Rule 1.12 in order to determine the appropriate conduct in connection with this Rule.

Client Under a Disability

17. In some situations, Rule 1.02(g) requires a lawyer representing a client under a disability to seek the appointment of a legal representative for the client or to seek other orders for the protection of the client. The client may or may not, in a particular matter, effectively consent to the lawyer's revealing to the court confidential information and facts reasonably necessary to secure the desired appointment or order. Nevertheless, the lawyer is authorized by paragraph (c)(4) to reveal such information in order to comply with Rule 1.02(g). See also paragraph 5, Comment to Rule 1.03.

Mandatory Disclosure Adverse to Client

18. Rule 1.05(e) and (f) place upon a lawyer professional obligations in certain situations to make disclosure in order to prevent certain serious crimes by a client or to prevent involvement by the lawyer in a client's crimes or frauds. Except when death or serious bodily harm is likely to result, a lawyer's obligation is to dissuade the client from committing the crime or fraud or to persuade the client to take corrective action; see Rule 1.02(d) and (e).

19. Because it is very difficult for a lawyer to know when a client's criminal or fraudulent purpose actually will be carried out, the lawyer is required by paragraph (e) to act only if the lawyer has information clearly establishing the likelihood of such acts and consequences. If the information shows clearly that the client's contemplated crime or fraud is likely to result in death or serious injury, the lawyer must seek to avoid those lamentable results by revealing information necessary to prevent the criminal or fraudulent act. When the threatened crime or fraud is likely to have the less serious result of substantial injury to the financial interests or property of another, the lawyer is not required to reveal preventive information but may do so in conformity to paragraph (c) (7). See also paragraph (f); Rule 1.02(d) and (e); and Rule 3.03(b) and (c).

20. Although a violation of paragraph (e) will subject a lawyer to disciplinary action, the lawyer's decisions whether or how to act should not constitute grounds for discipline unless the lawyer's conduct in the light of those decisions was unreasonable under all existing circumstances as they reasonably appeared to the lawyer. This construction necessarily follows from the fact that paragraph (e) bases the lawyer's affirmative duty to act on how the situation reasonably appears to the lawyer, while that imposed by paragraph (f) arises only when a lawyer "knows" that the lawyers services have been misused by the client. See also Rule 3.03(b).


21. 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 1.15(a)(1). After withdrawal, a lawyer's conduct continues to be governed by Rule 1.05. However, the lawyer's duties of disclosure under paragraph (e) of the Rule, insofar as such duties are mandatory, do not survive the end of the relationship even though disclosure remains permissible under paragraphs (6), (7), and (8) if the further requirements of such paragraph are met. Neither this Rule nor Rule 1.15 prevents the lawyer from giving notice of the fact of withdrawal, and no rule forbids the lawyer to withdraw or disaffirm any opinion, document, affirmation, or the like.

Other Rules

22. Various other Texas Disciplinary Rules of Professional Conduct permit or require a lawyer to disclose information relating to the representation. See Rules 1.07, 1.12, 2.02, 3.03 and 4.01. In addition to these provisions, a lawyer may be obligated by other provisions of statutes or other law to give information about a client. Whether another provision of law supersedes Rule 1.05 is a matter of interpretation beyond the scope of these Rules, but sub-paragraph (c)(4) protects the lawyer from discipline who acts on reasonable belief as to the effect of such laws.

Permitted Disclosure or Use When the Lawyer Seeks Legal Advice

23. A lawyer's confidentiality obligations do not preclude a lawyer from securing confidential legal advice about the lawyer's responsibility to comply with these Rules. In most situations, disclosing or using confidential information to secure such advice will be impliedly authorized for the lawyer to carry out the representation. Even when the disclosure or use is not impliedly authorized, subparagraph (c)(9) allows such disclosure or use because of the importance of a lawyer's compliance with these Rules.
