Practice head(s):


‘Audens’ technical quality is exceptional.’

‘In my opinion, Leandro Núñez García is probably one of the best lawyers specialised in data privacy in Spain. He is a benchmark and with technical and communication skills that place him among the best lawyers in the sector in our jurisdiction.’

‘Leandro Núñez has solved many problems for me on a day-to-day basis and has faced very complex national and international cases. In addition, the proximity and treatment is excellent.’

‘I have worked mainly with Marcos Judel and Leandro Nuñez and I can highlight from them, in addition to their professional value, their dealings with colleagues and with the client, and their good sense and closeness. It is very difficult to find colleagues who combine the legal and technological aspects and all of the above aspects so well.’

‘I have had the opportunity to work with several firms, well-known firms on many occasions, but what is a differentiating element of Audens is its client orientation, rigour, closeness and above all the dedication and adaptation of the entire team on occasions with very little margin of time to complex situations in which they accompany the client to the end.’

‘Audens is one of the best law firms that I have worked with in data protection due to proximity, knowledge, speed of response and quality.’
