On July 29, the American Bar Association (ABA) issued Formal Opinion 512. The opinion provides essential guidance on the use of generative artificial intelligence (AI) tools by lawyers. It joins a growing list of similar State-based ethics opinions issued by bar associations attempting to wrestle with the implications of generative AI.
The opinion underscores the importance of maintaining competence, confidentiality, and ethical billing practices in the age of AI. Though these basics are nothing new, the ABA opinion is sure to set a precedent when it comes to more nuanced areas like billing. Legal professionals can look to the opinion as they integrate advanced technologies into their practice.
The Core Tenets of ABA Formal Opinion 512
- Competence:
The ABA’s Formal Opinion 512 emphasizes that lawyers must possess a reasonable understanding of the capabilities and limitations of generative AI tools. This involves continuous learning and staying updated on the latest advancements in AI technology. Lawyers are expected to verify the accuracy of AI-generated outputs, ensuring they meet the client’s needs and legal standards . - Confidentiality:
Protecting client information remains paramount. According to ABA Formal Opinion 512, lawyers must ensure that any data processed by AI tools is secure and not exposed to unauthorized parties. This includes understanding how AI tools handle data and implementing robust safeguards to protect client confidentiality . - Ethical Billing Practices:
The opinion mandates that lawyers bill clients for the actual time spent on tasks, rather than the time saved due to AI efficiency. This means that if an AI tool significantly reduces the time required to complete a task, lawyers should only charge for the actual minutes worked, not for the hours saved. This ensures transparency and fairness in billing practices .
ABA Formal Opinion 512 Compatibility with State-Specific AI Ethics Rules
Several states have also issued their own guidelines on the use of AI in legal practice. They tend to align closely with the ABA’s recommendations:
California:
California was an early adopter of AI ethics rules. Back in November 2023, the State Bar of California provided guidelines for the use of generative AI. The “Practical Guidance for the Use of Generative Artificial Intelligence in the Practice of Law” was their influential early effort. [Check out our detailed review here] It has detailed guidelines similar to the ABA’s Formal Opinion 512. These guidelines emphasize competence, confidentiality, and transparency, requiring lawyers to disclose their use of AI to clients and to anonymize client data before inputting it into AI systems.

Florida:
The Florida Bar’s Ethics Advisory Opinion 24-1 from January 2024, highlights the need to prioritize client confidentiality, ensure accurate and competent practice, and avoid unethical billing practices. Florida’s guidelines also address the use of AI in lawyer advertising. They aim to ensure clients are aware when they are interacting with AI rather than a human lawyer .
Texas:
The Texas State Bar is in the process of drafting AI ethics rules, expected to align with the principles outlined in the ABA’s Formal Opinion 512. These guidelines will likely emphasize competence, confidentiality, and ethical billing practices .
