Trayectoria profesional

Asier Díaz Oliveri is an Associate Lawyer at Zabalgo Family Lawyers. He specialises in Family Law and criminal law matters arising in family contexts. His work focuses on the legal and strategic analysis of family disputes, particularly those affecting children, the family home, assets and personal relationships.

Education and specialisation

He holds a Law degree from the University of the Basque Country and completed the Master’s programme for access to legal practice at the Complutense University of Madrid. He has also completed specialist training in Family Law, Childhood and Succession at ISDE Law & Business School.

His international education includes studies in European Civil and Criminal Law at Maastricht University in the Netherlands. This experience supports a comparative perspective in matters with cross-border elements and in the study of different European legal systems.

Professional practice

Asier began his professional career in a general-practice firm and, following his placement at Zabalgo Family Lawyers, joined the team as a lawyer. Since then, he has focused on Family Law and criminal law matters connected with family disputes, combining technical analysis, procedural preparation and close attention to clients.

Institutional activity and legal commentary

He has moderated sessions organised by the Family and Succession Law Section of the Madrid Bar Association (ICAM), including a discussion on the evidential value of private-investigator reports in family and succession proceedings. This work complements a professional practice centred on evidence, case law and the practical issues arising in family proceedings.

He also contributes to legal commentary. He is the author of La vivienda, una preocupación decisiva en cualquier divorcio, published by Law&Trends, and has contributed to an analysis of recent Supreme Court case law in Family and Succession Law published in El Economista.

His objective is to offer clear and rigorous guidance in situations with a significant personal impact, helping clients assess their legal options before taking decisions that may have lasting consequences for their family.
