Immigration Attorneys in Spain

what guides us

Who We Are

We are the legal firm for foreigners in Spain. We are dedicated to solving problems for foreigners who live, want to live, or have interests in Spain, whether for work, business, family, studies, or investments.

Among the problems we solve are obtaining or renewing residence permits, setting up a branch or representative office for foreign companies, and obtaining Spanish nationality. We deal with issues such as divorce and prenuptial agreements between foreigners in Spain, international taxation, taxation of non-residents in Spain, international social security, inheritance, and cross-border debt claims.

We represent non-resident foreigners in the courts in Spain, we fight at all levels of Spanish and European justice against refusals of visas, residence permits or nationality, and we resolve disputes with the Tax Authorities, Social Security or the State Administration.

Mission

Protecting and defending the people who use our services from the complexities of Spanish bureaucracy, allowing them to enjoy all the good things our country has to offer.

Vision

To be the leading firm in Spain for immigration and international business expansion, recognized for our personal approach, speed, and efficiency, and for helping thousands of clients build their future in Europe.

Purpose

Our purpose is to ensure that every person and every company that chooses Spain can take that step with clarity, confidence, and support. We exist to transform bureaucracy into solutions that open up opportunities, and to closely accompany those who seek to grow, invest, or start a new stage of life in Spain and Europe.

How did we get started?

Our story

ILLAY Legal was founded as an immigration consultancy by two young Barcelona lawyers, Marc Pairó and Darío Cerisole, in early 2020, just before the pandemic. The two had been practicing immigration law in Barcelona for several years and decided to join forces. Shortly thereafter, another young Barcelona lawyer, María Prades, joined them.

Thanks to the team’s performance, satisfied clients continued to recommend ILLAY Legal to their friends and acquaintances, and the number of clients grew without advertising. It was decided to move to a model of specialization of functions.

In 2024, ILLAY legal entered into a business partnership with the renowned labor law firm Bufete Suárez de Vivero to continue expanding its immigration services to large companies and multinationals. The partnership made it possible to respond to requests for international tax, commercial, civil, labor, and social security services.

In 2025, ILLAY legal has more than 20 employees of 15 different nationalities who serve clients in more than 10 different languages, including Spanish, English, French, Brazilian Portuguese, Russian, Albanian, Turkish, Moroccan Arabic, Chinese, Serbian, Italian, Finnish, and Polish.
