The Firm


BUFETE TRALLERO is a business criminal Law firm devoted to the resolution of conflicts and advice in complex litigations regarding companies, executives and assets. BUFETE TRALLERO carries out his activity mainly in Spain, Europe and Latin America, with a track record of more than thirty years for his main partner, Alfonso Trallero, as well as Prof. Miguel Bajo, who was pioneer of business criminal Law in Spain until his death in 2019.

During this long period of time, the Firm has positioned itself as a reference in the white-collar crime field. BUFETE TRALLERO is highly specialized in proceedings before the Supreme Court, the National Courts, and the Anti-Corruption Prosecutor's Office. Besides, the active participation of its members in the most important criminal cases of the Spanish judicial history of the last decades, many of them with international projection and relevance, has allowed the Firm to provide highly qualified advice to our clients for the resolution of conflicts involving them.
At the same time, the complexity of matters entrusted to us and the special dedication that we provide for such advice, have allowed the Firm to generate new references that lawyers and judges have considered to be valid answers to challenges in this area. All this, undoubtedly explains the several awards received by the Firm as well as Alfonso Trallero being selected by top legal directories, and the steady participation of its members in round tables, conferences and events addressing the complex issues that arise in the world of business criminal Law.

The Firm’s assistance combines the utmost legal rigor with the pursuit of excellence at work and absolute commitment to the client. We offer the best solution for each matter, with absolute respect for professional ethics and minding that Justice is applied as faithfully as possible. Always with honesty, discretion, customization, prudence, firmness and maximum technical competence.
Throughout this long journey, dedication and a vocation for excellence have defined our actions. Following the path set by our founders, the Firm has been growing without ever renouncing to a customized and attached to the client's interests approach. We believe in the importance of nuances and the fact that only a deep handcrafted dedication can offer the best solution to our clients' problems. That is why we face each new matter as an exciting challenge to respond to. Thus, although we start from the gathered vast professional experience and the previous satisfactory results in similar cases, we refocus each new assignment to achieve the best defense for the interests of our clients.


MIGUEL BAJO FERNANDEZ, who passed away in April 2019, founded Gabinete Jurídico Miguel Bajo in 1980, incorporating ALFONSO TRALLERO in 1991, with whom he finally co-founded BAJO & TRALLERO ABOGADOS in 2011.
