- ‘The team is very up-to-date on all topics. For us, what makes the Mijares team unique and different from other firms is the teamwork between the different areas; it is a comprehensive consultation that covers all angles, with very well-prepared lawyers.’
- ‘They have good coordination among themselves and with the different partners of the firm. It is common for other firms’ internal bureaucracy to make them slow; this is not the case here.’
- ‘They take an interest in understanding the case well in order to reach a solution. They know the subject matter, similar cases, and the reasoning behind the regulation.’
- ‘I have had frequent contact with the lawyer Paula Pérez Benítez; she knows the subject very well and is often aware of international trends. I find the way they divide each aspect of a problem to address it specifically is very effective.’
- ‘Eugenio Macouzet and Bernardo Solorzano, from the Real Estate team, are lawyers who stand out for their sharpness in the matters they handle. They pay great attention to detail and are always available.’
- ‘Gabriel Calvillo is a criminal lawyer, which is a novel background in this field, and he has very good knowledge of environmental crimes.’
