Navigating AI Legal Implications: A 2026 Guide for Professional Services Firms

Artificial Intelligence is already transforming the way professional services firms operate by improving efficiency, decision‑making, and client experience. But as adoption accelerates, so too do the legal, regulatory and ethical considerations.

Our Technical Director Matt Taylor recently attended an event held by the Moore Barlow team looking into the current “legal risks, responsibilities and realities” of using AI.

Recent guidance from UK regulators makes one thing clear: senior leaders must treat AI as a governed business process, not just a productivity tool.

The Evolving Regulatory LandscapeUK: ICO Guidance on AI

In the UK, the ICO has issued updated guidance which emphasises fairness, transparency and accuracy in AI systems, including requirements for clear lawful bases, strict purpose limitation, and strategies to mitigate algorithmic bias.

EU: AI Act and High-Risk Systems

Across the EU, the AI Act is now in force, setting risk‑based obligations that affect UK organisations serving EU clients or using EU‑trained tools. High‑risk systems—common in finance, employment, credit assessment and aspects of legal work—must meet stringent documentation, human oversight and data‑governance requirements.

Legal Profession Guidance from the Bar Council

For legal practitioners, the Bar Council’s updated 2025 guidance reinforces that lawyers remain fully responsible for the output of AI systems, and must safeguard confidentiality, accuracy and privilege, regardless of the tools used.

Key legal risks for professional services firms

Senior leaders in regulated industries should be aware of several high‑impact areas:

Data protection exposure

AI systems process large volumes of personal and sometimes sensitive data, triggering UK GDPR duties around lawful basis, explainability, automated decision‑making and transparency.

Bias, fairness & discrimination

AI‑driven decisions in hiring, client due‑diligence, credit scoring or matter triage may breach the Equality Act if not carefully assessed and audited.

Confidentiality & privilege

Use of external AI systems can inadvertently expose sensitive data, weakening legal privilege or breaching contractual obligations.

Accountability & liability

Firms remain liable for errors, hallucinations or inaccurate outputs produced by AI systems, particularly in client deliverables, financial assessments and legal work.

IP ownership & training‑data risks

Unlicensed training data and AI‑generated content raise copyright and ownership concerns.

Practical AI Compliance Steps for Senior Leaders

Below are practical steps you can implement immediately:

  • Create (or update) an AI governance policy aligned to ICO expectations on fairness, transparency and accuracy.
  • Conduct an AI‑specific Data Protection Impact Assessment (DPIA) for every tool processing personal data.
  • Define approved vs. banned use‑cases to ensure AI is used only in legally and ethically permissible scenarios.
  • Implement human‑in‑the‑loop review for all client‑facing outputs, particularly legal, financial and risk assessments.
  • Update contracts and supplier due‑diligence to cover training‑data sources, IP ownership, data‑handling and liability boundaries.
  • Train staff on responsible AI use, including confidentiality, privilege, and verification processes

Future-Proofing Your Professional Services Firm for AI

As AI adoption soars in the world of professional services, legal and regulatory obligations cannot be left as an afterthought. AI is beyond being just a productivity tool; it has significant implications for data protection, bias, confidentiality, liability, and intellectual property.

Implementing robust AI governance policies, which should include conducting thorough Data Protection Impact Assessments, ensures that all important human oversight, and allows staff to be trained in responsible AI use. This can help firms mitigate those legal risks whilst still harnessing the benefits that AI undoubtedly offers.

Staying ahead of both the UK and EU regulations is a compliance necessity that also protects your clients and maintains the trusting relationship that you have worked hard to build with them. Reputation is still everything; even in this AI driven world.
