Spanish legal experts recently gathered for a webinar titled “Ciclo de diálogos sobre la Inteligencia Artificial: Responsabilidad y diligencia profesional en el uso de la IA”, held on February 12, 2026. Moderated by Magistrate María del Mar Hernández from Madrid’s Provincial Court (Section 28), the discussion featured Magistrate Joaquín Delgado Martín from the National Court’s Criminal Chamber and Ana Martín García, Dean of the Zamora Bar Association and President of the Spanish General Council of the Bar’s Innovation and Technology Commission.
The session explored how AI tools are reshaping legal practice and judicial processes, urging lawyers and judges to adopt them responsibly amid growing ethical and legal pitfalls.
Core Topics: Risks and Ethical Challenges
Participants dissected the profound implications of algorithmic tools in sensitive fields like law. Key areas included:
- Legal and disciplinary liability: Lawyers face civil and professional sanctions if AI-generated outputs lead to errors, such as flawed case strategies or misfiled documents.
- Confidentiality and data protection: AI systems trained on client data risk breaches under GDPR, demanding strict oversight to prevent unauthorized disclosures.
- Evidentiary pitfalls: Phenomena like AI hallucinations (fabricated facts) and deepfakes threaten trial integrity, especially in witness testimonies or forensic evidence.
- Regulatory frameworks: The Spanish General Council of the Judiciary’s recent instruction and the Bar Associations’ White Paper emerged as vital guides for ethical AI integration.
As AI permeates drafting contracts, predicting outcomes and analyzing precedents, the panel stressed that blind reliance equates to negligence. “Diligencia profesional” (professional diligence) now requires verifying AI results, much like double-checking human research.
Key Insights from the Speakers
María del Mar Hernández: Setting the Stage
The moderator opened by framing AI’s dual role: a productivity booster for routine tasks (e.g., summarizing case law) and a potential liability trap in high-stakes litigation. She highlighted courts’ growing scrutiny of AI-assisted filings, citing early cases where hallucinated citations led to sanctions.
Joaquín Delgado Martín: Judicial Perspective
The National Court magistrate focused on criminal proceedings, warning that deepfakes could fabricate alibis or tamper with video evidence. He advocated mandatory disclosure of AI use in submissions, akin to expert witness rules, and praised the Judiciary’s instruction for mandating judicial training on AI biases.
Ana Martín García: Bar Association View
Representing lawyers, García emphasized deontological codes evolving to cover AI. She noted the White Paper’s call for “human-in-the-loop” protocols—lawyers must oversee, not outsource, judgment. Bar sanctions could mirror those for plagiarism if AI outputs violate originality duties.
Why This Matters for Legal Professionals
Spain’s webinar reflects a Europe-wide push as AI adoption surges: 40% of law firms now use tools like ChatGPT or Lexis+ AI, per recent surveys. Yet, without diligence:
- Civil risks: Clients sue for malpractice if AI errors cause losses.
- Disciplinary actions: Bar ethics boards probe confidentiality lapses.
- Judicial rejection: Courts dismiss AI-tainted evidence, delaying justice.
The dialogue urged proactive steps:
- Training mandates: Annual AI ethics courses for bar members.
- Tool audits: Vet vendors for transparency and bias mitigation.
- Disclosure norms: Flag AI assistance in filings to maintain trust.
Broader Implications for Justice and Society
This discussion underscores AI’s transformative yet precarious role in justice systems. While speeding up research and access to law, it amplifies inequalities if only elite firms afford premium tools. Regulators must balance innovation with safeguards, ensuring AI augments—not supplants—human reasoning.
The panel concluded optimistically: with rigorous diligence, AI can enhance equity and efficiency. Future sessions in the cycle will tackle AI in sentencing and predictive policing.
