An AI system classified under Annex III of the EU AI Act as posing significant risk to health, safety, or fundamental rights, subject to conformity assessment before deployment.
EU RegulationThe EU AI Act's mandatory pre-deployment verification process confirming a high-risk AI system meets safety, transparency, and accuracy requirements before market placement.
EU RegulationThe EU's comprehensive AI regulation, in force August 2024, imposing risk-tiered obligations on AI developers and deployers — with legal sector compliance requirements escalating through 2026–2027.
EU RegulationThe EU AI Act's mandate that high-risk AI systems be designed to allow human monitoring, intervention, and override — directly applicable to legal AI tools used in client-facing or adjudicative contexts.
Move from this definition to role-based legal AI shortlists and the selection criteria that matter for each type of legal team.

ISO/IEC 42001, published in December 2023, is the first international standard specifying requirements for an artificial intelligence management system (AIMS). It follows the same high-level structure as ISO 27001 (information security) and ISO 9001 (quality), making it familiar to compliance teams. The standard covers AI risk management, impact assessment, data governance, and continual improvement processes across the AI lifecycle. Certification against ISO 42001 is voluntary but increasingly expected by enterprise clients and regulators.
Law firms and legal technology vendors that can demonstrate ISO 42001 certification — or alignment with its framework — signal to clients that AI is governed with documented controls rather than ad hoc practices. The standard is referenced in procurement questionnaires, and its risk assessment methodology maps well onto the EU AI Act's own risk management requirements. Firms advising clients on AI governance programmes should understand its structure and audit requirements.
