‘Marlen Estevez has expertise in her field and customer service. She undoubtedly stands out from her competitors.’
‘The dispute resolution department at RocaJunyent in Madrid has been exceptional. The ability to understand, analyse, present alternatives and strategies, build trust, and analyse risks has been incredible.’
‘Marlen Estévez Sanz and Borja Díaz-Puertollano have demonstrated a level of availability and easy access that is rarely found in large law firms. The brilliance of their approach and their overall analytical capacity for the cases that have been put to them has been exceptional.’
‘Compared to other firms, RJ always finds an optimal response and an adequate perspective on which to defend client interests, whether they are in a dominant position or not. They also know how to identify whether it is better to establish a negotiation or litigate in each case, always prioritising the client's benefit.’
‘When it comes to litigation, their excellence in the knowledge and practice of law is very evident, we only have to refer to the results obtained. And when it comes to negotiating with the opposing party, they know how to perfectly identify when they are in a dominant position and when they are not, establishing the best solution in each case. We cannot be more grateful for Gonzalo Serrano Fenollosa's work, treatment, and results obtained.’
‘RocaJunyent is the best partner for procedural disputes and arbitration. They have a great team of professionals led by Marlen Estevez. They are fast and they know the business and sector or which is key, especially for in out-of-court negotiations. They stand out from the rest of the offices.’
