Introduce a clientLegal advice from foreigners to foreigners
Islo Law Firm is a Madrid practice specialised in Spanish immigration and sports law. It advises foreigners and expats on immigration procedures, residence and Spanish nationality, and advises athletes, clubs and agents on sports law, with a clear, personal approach.
The firm is led by Rafaela Dias, a lawyer registered in Brazil, Spain and Portugal. An expat herself, she worked at Sagardoy Legal & Expat for more than two years before leading Islo, and the practice keeps that perspective: legal advice from foreigners to foreigners.
The firm's own framing is that legal procedures create uncertainty and worry. So it explains each step of the process in plain terms, anticipates the difficulties, and adapts the legal solution to each client's situation.
“Legal advice from foreigners to foreigners, close, clear and adapted to each personal situation, at every step of the way.”
Registered in three countries
Rafaela Dias is registered as a lawyer in Brazil, Spain and Portugal, and spent more than two years at Sagardoy Legal & Expat before leading the firm.
