Introduction: Navigating Oregon's AI Landscape

Artificial intelligence tools have arrived in Oregon's legal landscape, bringing both powerful opportunities and ethical risks for solo and small firm practitioners. Unlike larger firms with dedicated ethics committees, you must navigate AI's complex ethical landscape personally while managing your practice.

Oregon's Formal Opinion No 2025-205 now directly addresses AI use in legal practice with qualified approval—meaning AI is permissible, but only with proper safeguards. This guide provides practical steps to ethically implement AI in your Oregon practice while meeting your professional obligations under Oregon Rules of Professional Conduct (RPC).

Understanding Oregon's AI Ethics Framework

Oregon permits lawyers to use AI tools with qualifications. The Oregon State Bar has established clear guidelines centered around several core ethical duties:

• Competence: Oregon RPC 1.1 requires lawyers to be competent in both the law and the tools used to provide legal services
• Confidentiality: Oregon RPC 1.6 mandates protecting client information when using technology
• Communication: Oregon RPC 1.4(b) requires providing enough information for clients to make informed decisions
• Supervision: Oregon RPCs 5.1 and 5.3 establish responsibility for overseeing AI use

The risks are significant. AI tools can generate "hallucinations" or fabricate cases and citations, as demonstrated in cases like Mata v. Avianca, where attorneys faced sanctions for submitting AI-generated false case citations. Understanding these risks is essential for ethical practice in Oregon.

Competence: Becoming AI-Proficient in Your Oregon Practice

Under Oregon RPC 1.1, competence now extends to understanding the technology you use. The Oregon opinion specifically states that "lawyers may utilize AI in their legal practice only if they have taken reasonable steps to become competent in the use of such technology."

Practical steps for meeting this obligation include:

• Start with focused learning: Begin with a single AI tool for a low-risk task, like drafting standard discovery requests relevant to Oregon Civil Procedure
• Weekly knowledge-building: Allocate 30 minutes weekly to learning about AI tools specifically applicable to Oregon practice
• Create verification protocols: Develop checklists to confirm any AI-generated Oregon case citations or statutory references
• Connect with local peers: Join Oregon State Bar sections addressing legal technology
• Regular ethics updates: Review Oregon Bar Bulletin articles quarterly for new guidance

Tools like Clearbrief's citation verification can support your competence obligation by automatically flagging potential errors in legal citations, helping ensure accuracy in Oregon court filings.

Protecting Client Confidentiality with AI in Oregon

Oregon RPC 1.6 takes on new dimensions when using AI. The Opinion specifically warns that some "GAI products may produce hallucinations or collect user prompts to train the product for use by other future users," creating confidentiality risks.

To maintain confidentiality in your Oregon practice:

• Review terms carefully: Examine data retention policies of AI tools before use
• Understand AI models: Oregon's opinion distinguishes between "open" and "closed" AI models; closed models generally offer greater confidentiality protection
• Obtain informed consent: Oregon requires client informed consent when using client information in open AI models
• Consider legal-specific tools: Platforms like Clearbrief offer enhanced security features with SOC 2, Type 2 certification and "Bring Your Own Storage" options that align with Oregon's closed-model AI preference
• Anonymize information: When using open models without consent, Oregon requires thoroughly anonymizing client information

Client Communication: Transparency About AI Use

Oregon RPC 1.4(b) requires providing clients with enough information to make informed decisions. The Oregon Opinion notes that while word processing and research databases are generally considered "impliedly authorized," newer AI technologies may need explicit disclosure.

For effective client communication:

• Update engagement letters: Include clear AI use policies in your Oregon practice agreements
• Evaluate case-by-case: Oregon requires individual evaluation of each matter to determine if AI use requires client notification
• Consider key factors: The opinion lists relevant factors including case type, technology novelty, client sophistication, data risks, and fee impacts of using AI
• Document client preferences: Record specific client instructions regarding AI use
• Demonstrate verification: Show clients how you verify AI outputs, such as through citation-checking tools like Clearbrief

Ethical AI Billing Practices for Oregon Attorneys

Oregon RPC 1.5 governs fees and expenses related to AI use. The opinion offers specific guidance:

• Bill only reasonable time: You may charge for case-specific research and drafting with AI
• No charging for AI competence: Oregon prohibits charging clients for time spent developing your AI competence
• Inform clients about costs: Disclose, preferably in writing, if you intend to charge for actual costs of using AI
• No general research billing: Clients may not be charged for AI-assisted research of a general nature
• Overhead vs. direct costs: For AI tools that can't be attributed to specific client matters, account for costs as overhead

Implementing AI Supervision in Small Oregon Firms

Even solo and small firms must establish clear AI policies under Oregon RPCs 5.1 and 5.3. The opinion emphasizes that managers must create "effective measures" and supervisors must make "reasonable efforts" to ensure compliance.

Practical approaches include:

• Develop a concise AI policy: Create a straightforward one-page guide for your Oregon practice
• Train staff appropriately: Conduct brief training on ethical AI use, emphasizing Oregon requirements
• Create review protocols: Establish clear procedures for reviewing AI-generated content
• Understand AI differences: Oregon emphasizes that supervisors must ensure staff understand the difference between open and closed AI models
• Document verification: Maintain records showing how AI outputs are verified before submission

Ensuring Candor to Oregon Courts

Oregon RPC 3.3 prohibits knowingly making false statements to a tribunal. The opinion cautions that "the most obvious way in which a lawyer could run afoul of Oregon RPCs 3.3 and 4.1 is through the submission of and reliance on unverified and fictitious cases, citations, quotes, or conclusions generated by AI."

To maintain court candor:

• Check court requirements: Verify whether Oregon courts have specific AI disclosure requirements
• Review all AI output: Carefully examine any case-specific facts or citations
• Verify cases exist: Confirm all AI-generated Oregon case law references
• Correct promptly: If errors are discovered, notify the court and correct without violating client confidences
• Use verification tools: Consider tools like Clearbrief that automatically verify citations against original sources

Conclusion: Balancing Innovation and Ethics in Oregon

Oregon's approach to AI in legal practice balances innovation with professional responsibility. By understanding the qualification requirements around competence, confidentiality, communication, and verification, small and solo practitioners can ethically harness AI's benefits while protecting clients and maintaining professional standards.

Remember that AI tools should enhance your legal judgment, not replace it. Each AI implementation requires thoughtful consideration of your ethical obligations as an Oregon attorney. By following these guidelines and leveraging appropriate verification tools, you can deliver more efficient and effective client service while maintaining full ethical compliance.
