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.

 Trustindex verifies that the original source of the review is Google. I had an amazing experience working with Dario and his team throughout my visa process. They made everything completely stress-free and were incredibly helpful every step of the way. Dario speaks excellent English, which made communication easy and comfortable, and he was always responsive, patient, and clear in explaining everything. He and his colleagues handled every detail with care, efficiency, and in a very timely manner, which gave me a lot of confidence and truly made my life so much easier throughout the entire process. By far the best lawyer I’ve worked with in Barcelona. I couldn’t have asked for a better experience and would highly recommend Dario and his team to anyone needing help with visas or immigration.

 Trustindex verifies that the original source of the review is Google. A friend recommended Illay Legal  to help obtain my permanent residency in Spain. Exceptional service! Marc explained every part of the process clearly and precisely. Once I provided all the necessary details, the team did all the work: pre-completed the necessary paperwork, helped retrieve padron and digital tax certificate, secured appointments in my preferred neighbourhood and checked in with me before and after both appointments. I subsequently switched both my tax and business accountancy contracts to Marc's firm and have enjoyed the same very high level of service. Communication via email and WhatsApp, and extremely responsive to answering any small or large questions/concerns. A huge endorsement to the whole team - I would highly reccomend. Regards Ismail

 Trustindex verifies that the original source of the review is Google. Lawyers I truly trust and genuinely enjoy working with. Huge thanks to Marc and Soundous for guiding me through a very stressful documentation process over the past few years. Together we managed to resolve a complicated situation I ended up in because of a bureaucratic issue with my previous paperwork. They have well-organized processes and a lot of experience with different kinds of cases — even the tricky ones. Whenever I was stressed or freaking out, they were always there to reassure and support me. That human approach means a lot. With them, you are in very good hands 💚
