Q: Does a lawyer who uses AI to draft a document need to disclose this to the client?

The EU AI Act transparency obligation applies to interactive AI systems, not to AI used as a drafting aid. However, professional conduct rules in many jurisdictions are developing guidance on disclosure of AI use to clients. Lawyers should monitor their bar association's evolving guidance independently of the AI Act.

Q: What constitutes sufficient disclosure that a user is interacting with AI?

A clear, prominent notice at the start of an interaction — stating that the user is communicating with an AI system — generally satisfies the Article 50 requirement. Burying the disclosure in terms of service or using vague language (such as "automated assistant") is unlikely to be sufficient. --- *Last reviewed: 2026-05-19 by LawyerAI Editorial Team.*
