Excellent attention to detail and personal availability of partners and associates.

Warmth, empathy and agility.

The different lawyers have a lot of specialisation and very good coordination of cases as well as communication between themselves to resolve matters. They act and proceed quickly within the constraints of following the law and making everything transparent. The good thing about this is that many government offices have respect for them.

All the lawyers are very professional and specialists in their field. They fully adhere to the law, looking for solutions but ensuring the proper implementation of the law and within it. They are responsible in their actions and recommendations. Highly recommended. I deal with and admire Eduardo Mayora and Paola Galich.

Mayora & Mayora has teams which work well together, with highly qualified and fair-minded people. They provide reliable advice which gives us the information we need to make decisions about resolving complex situations.

We can see how interested the partners are in our cases from the way they dive into the subject matter – not just the legal theory and general regulations, but also the specific situation, which is an ideal combination to provide advice based on experience and knowledge of the individual case.
