About us
A Firm Created to Simplify International Mobility to Spain
Who we are
Legal clarity for international clients
After more than 10 years in the immigration sector, our founder, Maryem Essadik, recognized a recurring problem. International clients relocating to Spain were often forced to coordinate multiple providers across immigration, tax, real estate, and corporate matters, creating a fragmented and unnecessarily complicated process.
Marfour was created to change that.
Today, Marfour brings together immigration, tax, real estate, corporate, labor, and accounting services under one multilingual firm, providing international clients with a more seamless and efficient approach to relocation and investment in Spain.
As a boutique international law firm, we combine legal expertise with a highly personalized approach. Rather than offering one-size-fits-all solutions, we tailor our services to each client’s specific objectives, circumstances, and long-term plans.
With offices in Barcelona and Madrid, Marfour supports expatriates, investors, families, entrepreneurs, and companies navigating life and business in Spain.

I HIGHLY recommend Marfour International Law firm! The lawyers are organized, responsive, kind, and extremely competent. We were faced with a very rushed situation in regard to getting a student visa situation resolved quickly and we were facing a lot of challenges. The staff at Marfour knew exactly what to do and how to do it. They walked us through every step of the process. We had an extremely tight time frame for getting everything figured it, and the lawyers were able to help us meet this deadline. They explained very clearly how to overcome our obstacles to ensure compliance with the law. I very much would use them again.Publicado en Anna PorterTrustindex verifica que la fuente original de la reseña sea Google. Thanks for your great work and getting our NLVs.

Thanks and recommend this law firm and specially Marina and Carlota;Who helped during the whole process. Honestly without you girls we could not have done It. Thanks a lotPublicado en Melissa MetzgerTrustindex verifica que la fuente original de la reseña sea Google. We can’t recommend our lawyer, Carlota Monreal, highly enough for helping our family secure our Digital Nomad visas in Spain. She was patient, thorough, and always available to answer our many (many) questions. Having a family application can feel overwhelming, especially since we also had an adult “dependent” (18 year old) on the application, but Carlota handled everything with care and professionalism, giving us peace of mind in what can be a stressful situation. Her attention to detail, deep understanding of the process, and thoughtful responses to the visa office on our behalf made all the difference. We’re truly grateful for her support in receiving our positive resolutions and would highly recommend Carlota Monreal to any individual or family navigating Spanish immigration.Publicado en Jennifer BarriosTrustindex verifica que la fuente original de la reseña sea Google. The team at Marfour Law is wonderful, especially Marina and Marc. Both were very thorough in explaining complex processes and even cultural nuances. Marc has over 2 decades experience in Spanish tax law and was also incredibly kind, which was a pleasant bonus as we navigated my unique case. I highly recommend their services if you are looking for a professional, trust-worthy law firm.Publicado en Sara VratonjicTrustindex verifica que la fuente original de la reseña sea Google. I started collaborating with Marfour for my relocation to Spain, and the experience has been genuinely great. From day one, the team was kind, helpful, and incredibly timely. Marina, my first point of contact, clearly explained every step of the process and helped me understand the full picture of what I needed to prepare and what the relocation would look like. She patiently listened to my story and helped me choose the best way for my successful relocation. At that point, I was choosing with whom I could collaborate for my relocation, and Marina's proactive and supportive approach definitely made this decision easy for me. For the more complex questions, Marc immediately stepped in and took the time to walk me through every single detail I needed to know. He was so thorough, approachable, and his explanations and advice meant the world to me! Last but certainly not least, I would like to leave here a very special thanks to my dedicated lawyer, Carlota Monreal. I can confidently say that without her guidance, I would have felt completely lost in all the steps. Firstly, she is extremely knowledgeable and organized, and she made sure I was well prepared for each step of the process. Secondly, beyond her expertise, Carlota was always available to answer any question I had, calm my worries, and support me with her patience and a genuinely kind, human approach. That meant a lot to me! It makes a world of difference to go through a stressful process of relocation knowing you have someone you can trust by your side, not just on an expert level but on a human level, too. And as a result of all this, I got my visa! I’m truly glad I chose Marfour to support me in my relocation process and grateful for their whole team and their professionalism, clarity, and kindness. I recommend this team 100%.Publicado en Angel OnwukweTrustindex verifica que la fuente original de la reseña sea Google. I have had another very positive experience with Marfour International Law Firm, this time for my parents’ family reunification process. As with my previous HQP application, the service was handled with professionalism, clarity, and efficiency. I would especially like to thank Carlota Monreal for her excellent support and dedication. She handled this case with great care, clear communication, and attention to detail, guiding me through every step of the process. Thanks to her work, my parents’ residence permits were successfully approved. I highly recommend Marfour Law and Carlota Monreal for dependable and professional immigration legal services.
