The EU AI Act designates certain AI systems as "high-risk" based on their intended use rather than their technical architecture. Annex III lists eight domains where AI systems are presumed high-risk, including employment decisions, access to essential services, and administration of justice. Systems in these categories must undergo conformity assessment, maintain technical documentation, and meet ongoing transparency and oversight requirements before they can be legally deployed in the EU.
Legal professionals must understand whether the AI tools they use — or advise clients on — fall into a high-risk category, because deployers as well as providers carry obligations. AI tools used in court proceedings, legal aid allocation, or employment-related legal work may meet the Annex III threshold. Failure to comply exposes both the vendor and the deploying law firm or legal department to regulatory enforcement.
