Compendium of Professional Responsibility Rules and Standards, 2026 Edition: 2026 Edition

The Compendium presents models for ethical and professional conduct and standards for enforcing that conduct that have been developed by the American Bar Association. These models have been used as the foundation for most state regulations and as interpretive guidance for the courts in their resolution of professional responsibility issues. Despite the local variations in the way they have been adopted (occasionally significant), they serve to familiarize the reader with the philosophy of lawyer regulation and can be used to initiate review of substantive issues unfamiliar to the lawyer, student or scholar.

In addition, the Compendium contains a selection of federal Rules and Standards that are commonly needed in the general practice of law, and in practice before the SEC and IRS, and that impact upon a number of ethical rules of conduct, such as the rules regarding competence and meritorious claims and contentions. Information on the composition, jurisdiction and procedures of the ABA Standing Committee on Ethics and Professional Responsibility is included to explain how ABA ethics rules are formulated and interpreted. The 2026 Edition includes newly released ethics opinions.

This one volume includes:

• ABA Model Rules of Professional Conduct

• ABA Model Rules Related to Multijurisdictional Practice
