Ester Martín

Her practice focuses on complex criminal proceedings, advising and representing both the prosecution and the defence at all stages (judicial investigations and criminal trials). She has represented senior executives and corporate entities in high-stakes matters involving significant legal, financial and reputational risk. Her profile covers a broad range of corporate criminal offences affecting listed companies, including environmental offences, corruption, tax fraud, money laundering, investment fraud, accounting irregularities, and offences arising from the marketing and sale of financial products.

In addition to her litigation practice, Ester regularly advises companies and other entities on corporate criminal liability, with a particular focus on the design, implementation and enhancement of compliance programmes, crime prevention frameworks and best practices in corporate governance.

She also has experience in internal investigations, both in pre litigation contexts and in response to whistleblowing reports, advising companies on corporate defence strategies and on their interactions with criminal, administrative and regulatory authorities.

Since 2023, Ester has been a Lecturer in Criminal Law at the Universidad Internacional de la Empresa (UNIE) in Madrid, combining her professional practice with a strong academic background.
