Award-Winning Spanish Law Firm Recognised in the Lawyer International – Legal 100 Awards 2025

Geijo & Associates, headquartered in Madrid, Spain, has firmly established itself as one of Europe’s leading firms in the fields of international criminal law, human rights, and cross-border defence. Under the direction of Arantxa Geijo Jiménez, the firm has gained global recognition for its expertise in high-stakes, multi-jurisdictional cases—particularly those involving INTERPOL Red Notices, extradition, and politically sensitive prosecutions.

With a clear mission to uphold justice beyond borders, Geijo & Associates has become a trusted name in the international legal community, providing legal clarity and strategic defence for individuals and organisations facing serious legal threats across continents.

Specialising in Complex International Legal Challenges

At its core, Geijo & Associates provides specialist legal counsel for international criminal defence and human rights matters. Their work spans:

Challenging INTERPOL Red Notices
Defending clients in extradition proceedings
Protecting human rights under international treaties
Advising on politically motivated prosecutions
Providing strategic legal representation in multi-jurisdictional disputes

These are not just legal services—they’re lifelines for individuals and organisations caught in politically charged or unjust legal proceedings. The firm’s clients include asylum seekers, political dissidents, journalists, NGOs, foreign nationals, and even state actors requiring discrete advisory services.

Recognised Legal Excellence – Legal 100 Award Winner 2025

In 2025, Geijo & Associates was awarded “International and Criminal Lawyer of the Year” by the Lawyer International – Legal 100 Awards. This recognition reflects not only the firm’s legal excellence, but also its moral conviction and leadership in protecting the fundamental rights of individuals worldwide.

“This award validates our unwavering commitment to justice and strengthens our resolve to keep challenging legal systems that abuse power,” said Arantxa Geijo, Managing Partner of the firm. “It is a testament to the dedication, expertise, and integrity of our entire team.”

The Legal 100 Awards are globally respected and highlight only the top firms in their category—underscoring the significant role Geijo & Associates plays on the world stage.

INTERPOL Defence – A Leading Global Practice

One of the firm’s key areas of expertise is INTERPOL defence. With misuse of Red Notices becoming increasingly common, especially by authoritarian regimes seeking to silence dissidents, the need for expert legal defence has never been greater.

Geijo & Associates has successfully challenged numerous unlawful Red Notices, helping clients restore their freedom of movement, protect their reputation, and reclaim control over their legal destiny. Their knowledge of INTERPOL’s internal mechanisms, combined with their understanding of international law and data protection, gives them a critical edge in this highly specialised area.

Cross-Border Legal Defence with Global Reach

International law isn’t just about understanding treaties—it’s about coordinating across legal systems, languages, and time zones. Geijo & Associates operates through a global network of trusted legal partners, interpreters, forensic experts, and human rights advocates to build airtight defence strategies for their clients.

With the ability to handle cases across Europe, Latin America, Africa, and the Middle East, the firm provides a rare combination of local understanding and international capability. Each case is handled with discretion, strategic foresight, and an unwavering focus on protecting the client’s dignity and legal rights.

Human Rights Advocacy at Its Core

Geijo & Associates is more than a law firm—it is a vocal advocate for global human rights. Whether representing clients facing persecution, challenging government overreach, or advising NGOs on international legal frameworks, the firm’s values remain rooted in justice, accountability, and the protection of civil liberties.

The firm frequently works in cases related to:

Torture and inhumane treatment
Freedom of expression and political speech
Unlawful detention
State corruption and abuse of process
Asylum and refugee law

Through these cases, Geijo & Associates not only defends individual rights but contributes to the broader fight for rule of law and democratic values across borders.

Educating the Next Generation of International Lawyers

Beyond casework, the firm is committed to mentoring young legal professionals and advancing education in international criminal law. Through internships, academic partnerships, and public legal seminars, Geijo & Associates is actively shaping the next generation of global human rights defenders.

Arantxa Geijo has also been invited to speak at several international law conferences, where she shares insights into INTERPOL reform, the future of extradition law, and ethical dilemmas in transnational justice.

Looking Ahead: Strategic Growth and Global Advocacy

Geijo & Associates is now entering a new phase of growth. In the coming years, the firm plans to:

Expand its presence in key jurisdictions
Launch training initiatives for young lawyers
Strengthen digital legal capabilities
Broaden its portfolio of public interest cases
Collaborate with regional human rights institutions

Their mission is clear: to continue defending the most vulnerable, challenge systemic injustice, and set a global standard for legal integrity.
