Your Client Is Talking to ChatGPT About Their Case. After 'Heppner,' That's a Discovery Problem.

Key Takeaways

• Clients increasingly consult ChatGPT for case strategy advice
• Heppner ruling mandates disclosure of AI-generated communications
• Defense teams must expand discovery to capture chatbot interactions
• Failure to preserve AI chats risks sanctions and evidentiary loss
• Law firms are drafting AI-use policies to mitigate risk

Pulse Analysis

The Heppner decision marks a watershed moment for legal discovery, extending traditional document preservation rules to the realm of generative AI. Courts now view prompts, responses, and even the metadata of ChatGPT sessions as potentially relevant evidence, especially when a client relies on the tool for case analysis or strategy. This judicial stance forces litigators to treat AI interactions with the same rigor as emails or memos, prompting a reevaluation of evidence‑collection workflows and e‑discovery platforms.

For defense attorneys, the practical implications are immediate. Discovery requests must be revised to explicitly demand logs of AI usage, including timestamps, prompts, and the AI’s outputs. Failure to secure these records can lead to spoliation claims, adverse inference instructions, or monetary sanctions. Moreover, firms must educate clients about the risks of informal AI consultations, ensuring that any advice derived from ChatGPT is documented and, where appropriate, vetted by counsel before reliance.

The broader industry response is evolving quickly. Law firms are drafting AI‑use policies that define permissible interactions, mandate preservation of chat transcripts, and outline client consent procedures. Technology vendors are adding features to export and archive chatbot sessions in formats compatible with e‑discovery tools. As AI becomes entrenched in legal practice, the Heppner precedent underscores the necessity for proactive compliance strategies, balancing innovation with the duty to preserve the truth in litigation.
