I have approached Maria on more than one occasion for help and in each case I was given extensive, professional and correct advice both concerning our own property and Resort issues as well as personal problems. I cannot recommend highly enough. He recurrido a María en más de una ocasión para pedirle ayuda y, en cada caso, recibí un asesoramiento amplio, profesional y preciso, tanto sobre nuestra propiedad y el complejo turístico como sobre problemas personales. La recomiendo encarecidamente.

Fantastic and professional firm. They really stepped up during a negotiation with a tight deadline, working through multiple revisions with a singular focus on delivering the best possible results on my behalf. I was skeptical of contracting any legal help for the matter in question, and feel so vindicated because I could have never achieved the results they did. They truly have your back.

I had some questions about NLV visa and basic questions about taxes. Maria Castro was so kind to answer my emails and give me some guidance and even some interesting thing's I never thought of. Her answers were very concise and knowledgeable. The internet is full of misinformation. Go to a professional so you don't make a costly mistake. Thanks Maria. Now I know when I am ready who my lawyer will be.

The CostaLuz Lawyers were able to recoup 2 years worth of taxes paid in error to the Spanish government! I appreciate their professionalism and swift attention to detail. The office was always courteous and helpful. I had searched for help with my tax dilemma without success until I found CostalLuz! Thank you always!

Very professional and very knowledgable. Maria Luisa, María Carmen and Álvaro were extremely helpful. As a U.S. expat and permanent resident of Spain, I was having difficulty understanding why Spain was taxing me on my U.S. Social Security benefits. Álvaro helped me interpret the pertinent sections of the bilateral agreement and I came away with a much better understanding. I still have to pay taxes, but now I understand WHY. Thanks again to all of you!
