Cal. Rules of Prof. Conduct, rule 1.0
Purpose and Function of the Rules of Professional Conduct
Text — 2026 edition, as the State Bar of California publishes it (read October 22, 2026)
(a) Purpose.
The following rules are intended to regulate professional conduct of lawyers through discipline. They have been adopted by the Board of Trustees of the State Bar of California and approved by the Supreme Court of California pursuant to Business and Professions Code sections 6076 and 6077 to protect the public, the courts, and the legal profession; protect the integrity of the legal system; and promote the administration of justice and confidence in the legal profession. These rules together with any standards adopted by the Board of Trustees pursuant to these rules shall be binding upon all lawyers.
(b) Function.
(1) A willful violation of any of these rules is a basis for discipline.
(2) The prohibition of certain conduct in these rules is not exclusive. Lawyers are also bound by applicable law including the State Bar Act (Bus. & Prof. Code, § 6000 et seq.) and opinions of California courts.
(3) A violation of a rule does not itself give rise to a cause of action for damages caused by failure to comply with the rule. Nothing in these rules or the Comments to the rules is intended to enlarge or to restrict the law regarding the liability of lawyers to others.
(c) Purpose of Comments.
The comments are not a basis for imposing discipline but are intended only to provide guidance for interpreting and practicing in compliance with the rules.
(d) These rules may be cited and referred to as the “California Rules of Professional Conduct.”
Notes and commentary — not rule text
Comment
[1] The Rules of Professional Conduct are intended to establish the standards for lawyers for purposes of discipline. (See Ames v. State Bar (1973) 8 Cal.3d 910, 917 [106 Cal.Rptr. 489].) Therefore, failure to comply with an obligation or prohibition imposed by a rule is a basis for invoking the disciplinary process. Because the rules are not designed to be a basis for civil liability, a violation of a rule does not itself give rise to a cause of action for enforcement of a rule or for damages caused by failure to comply with the rule. (Stanley v. Richmond (1995) 35 Cal.App.4th 1070, 1097 [41 Cal.Rptr.2d 768].) Nevertheless, a lawyer’s violation of a rule may be evidence of breach of a lawyer’s fiduciary or other substantive legal duty in a non-disciplinary context. (Ibid.; see also Mirabito v. Liccardo (1992) 4 Cal.App.4th 41, 44 [5 Cal.Rptr.2d 571].) A violation of a rule may have other non-disciplinary consequences. (See, e.g., Fletcher v. Davis (2004) 33 Cal.4th 61, 71-72 [14 Cal.Rptr.3d 58] [enforcement of attorney’s lien]; Chambers v. Kay (2002) 29 Cal.4th 142, 161 [126 Cal.Rptr.2d 536] [enforcement of fee sharing agreement].)
[2] While the rules are intended to regulate professional conduct of lawyers, a violation of a rule can occur when a lawyer is not practicing law or acting in a professional capacity.
[3] A willful violation of a rule does not require that the lawyer intend to violate the rule. (Phillips v. State Bar (1989) 49 Cal.3d 944, 952 [264 Cal.Rptr. 346]; and see Bus. & Prof. Code, § 6077.)
[4] In addition to the authorities identified in paragraph (b)(2), opinions of ethics committees in California, although not binding, should be consulted for guidance on proper professional conduct. Ethics opinions and rules and standards promulgated by other jurisdictions and bar associations may also be considered.
[5] The disciplinary standards created by these rules are not intended to address all aspects of a lawyer’s professional obligations. A lawyer, as a member of the legal profession, is a representative and advisor of clients, an officer of the legal system and a public citizen having special responsibilities for the quality of justice. A lawyer should be aware of deficiencies in the administration of justice and of the fact that the poor, and sometimes persons* who are not poor cannot afford adequate legal assistance. Therefore, all lawyers are encouraged to devote professional time and resources and use civic influence to ensure equal access to the system of justice for those who because of economic or social barriers cannot afford or secure adequate legal counsel. In meeting this responsibility of the profession, every lawyer should aspire to render at least fifty hours of pro bono publico legal services per year. The lawyer should aim to provide a substantial* majority of such hours to indigent individuals or to nonprofit organizations with a primary purpose of providing services to the poor or on behalf of the poor or disadvantaged. Lawyers may also provide financial support to organizations providing free legal services. (See Bus. & Prof. Code, § 6073.)
