The EU AI Act (Regulation 2024/1689) entered into force on 1 August 2024 and represents the world's first comprehensive horizontal regulation of artificial intelligence. It applies a tiered risk classification — unacceptable, high, limited, and minimal risk — to AI systems placed on the EU market or affecting EU persons. Obligations vary by risk tier, with the most onerous requirements applying to high-risk systems and a phased enforcement timeline running through 2027.
Law firms and legal departments that procure or deploy AI tools must assess whether those tools fall under the Act's scope, particularly if they are used in HR, access to justice, or evidence analysis contexts. Legal professionals acting as deployers — not just vendors — bear direct obligations including risk management, transparency disclosures, and human oversight measures. Non-compliance carries fines of up to €35 million or 7% of global annual turnover.
