Naveira Truffat Martínez Abogados (NTMA)

'A firm that stands out for its technical solvency', disputes-focused boutique Naveira Truffat Martínez Abogados (NTMA) specialises in representing private companies and corporations in complex, primarily commercial litigation, particularly in bankruptcy and restructuring cases. The team is co-led by commercial litigation expert Daniel Truffat ('one of the best jurists in Argentina') and Oscar Martínez ('a top-notch professional both technically and commercially'), who focus on advisory, corporate assistance and complex disputes. Another key name is Valentín Tomás Martínez, a younger partner whose 'outstanding technical solvency' and 'extensive commercial knowledge' has made him a client favourite; he handles contentious and non-contentious corporate, bankruptcy and reorganisation proceedings.

Practice head(s):

Daniel Truffat; Oscar Martínez


Our experience with Daniel Truffat and Gustavo Naveira is always excellent.  Having recently worked with both of them in a very complex case that involved a corporate conflict that was settled in commercial justice and in an arbitration before ICC, I can confirm that both Daniel and Gustavo have extensive knowledge of commercial and especially corporate law,. The collaboration of the Naveira Truffat firm was very important for the successful completion of the matter and I would not hesitate to turn to them in a similar case. I also worked with them in the Parmalat bankruptcy where their firm worked as an advisor to the bankruptcy receivership and there they also demonstrated their great knowledge of bankruptcy law.

Daniel Truffat stands out for his knowledge of bankruptcy law, while Gustavo Naveira is an expert in commercial law. Both stand out not only for their knowledge of the law but also for their fine judgment when recommending procedural strategies. Both also stand out for their depth and clarity in the writing of judicial writings.’

The collaboration of the firm in all the matters on which we have worked together has been impeccable. Their knowledge of the commercial jurisdiction also stands out since both of them have been judicial officials in the past, which allows them to have a very acute sense of the operation of the different courts.’

Daniel Truffat and Valentín Martínez: Daniel is one of the most respected lawyers in Argentina and together with Valentín they make up a highly technical and dynamic team when it comes to customer service and the quality of his work. These are the strengths of the team and what sets them apart from other elite law firms in Argentina.’

Daniel Truffat is one of the best commercial lawyers of his generation and is currently an obligatory reference in matters of property, corporate and bankruptcy law. The simple act of listening to him and being represented by him gives us enormous security and confidence in the outcome of our conflicts. It is what in Argentina we call a “registered trademark” – a guarantee of trust and results.’

For his part, Valentín Martínez is a young partner in the firm; we highlight his great technical solvency and his agility in answering our questions and carrying out the tasks we entrust him with. Likewise, Valentín also has extensive commercial knowledge of the market in which we operate, a fact that is extremely important for the work to be more efficient. Together with Daniel they make up an elite litigation team in Argentina.

What differentiates NTMA from other firms we have worked with is the direct dealings with the partners who are in charge of the issue (without delegating this task to a semi senior lawyer) as well as the fact that it has established partners and at the same time has promoted young members. It really is a law firm that definitely does not think only in the short term.’

Regarding the legal service, NTMA is characterised by the technical solvency of its partners and associates, by the speed with which they work and, above all, by the 24/7 availability of all the partners with whom we have had the possibility of working.

Currently, our reference partner is Valentín Martínez. Valentín is a young lawyer with whom we feel extremely comfortable and satisfied because he combines two qualities that I consider fundamental in a great lawyer. On the one hand, he possesses an outstanding technical solvency, a fact that should be valued even more considering his age. On the other hand, we highlight the fact that, due to his great technical solvency, Valentín is characterised by his close dealings with us, which makes us feel understood and valued as if we were his best client.’

In short, Valentín has become not only our lawyer, but also the person to whom we turn for any consultation or advice that we require, a fact that definitely transforms him into a professional who stands out in relation to the rest of his competitors.’

Regarding collaboration, NTMA is characterised by the personal attention of its partners who always work as a team in order to provide the best possible service. In terms of billing they have always been very transparent and we have never had any inconvenience.’

They manage a constant availability and predisposition. They had a great adaptation, management and responses in this time of pandemic.’

They provide a very personal, dedicated, professional service of great professionalism. They not only take the case seriously and professionally but also very personally; They have a predisposition to facilitate the process not only on the professional side but also on the personal side of the client, they accompany and help with everything inside and outside the firm advising on a whole.’

‘They have a great combination of young people and a career where they approach the issues both from the experience and professional training of years and from the imprint, strength and modernity of the young.’

NTMA is a firm that stands out for its technical solvency and reputation in the market. The matter that we deal with with them must surely be one of the most relevant legal matters in the Argentine market with enormous legal technical complexity.

The depth with which the NTMA team works on issues and its great technical solvency highlights them above the rest of the legal firms in Argentina.

Daniel Truffat and Oscar Martínez are a “duo” of lawyers who have worked shoulder to shoulder for many years and who feel very comfortable working as a team so that their virtues stand out even more. Daniel is one of the best jurists in Argentina and Oscar is his ideal complement, since he has great legal ingenuity and extensive commercial knowledge of all the issues he deals with.

Likewise, it is essential to highlight the work that Valentín Martínez has done for our company. Without prejudice to the support of Daniel and Oscar, it was he who was in charge of initially studying all the files in which our company had interests and later who has been in charge of projecting the totality of the submitted writings. He is probably the one who has the most in-depth knowledge of the entire history of the litigation in which the NTMA team assists us. His contribution is truly invaluable and it is worth highlighting him as one of the best young lawyers in Argentina.’

It is also worth highlighting the collaborative work method used in which several partners participate in the design of the strategy and in the preparation of the documents that we must present in the different litigation in which we advise.’

NTMA is one of the most prominent law firms in Argentina. In terms of conflict resolution they are really very good. Our company is dedicated to the financial sector, which by definition is very dynamic. We have been working with NTMA for 4 years now and they have really helped us a lot both in the task of ordering our litigious conflicts and in their correct management.’

What I highlight about NTMA and that distinguishes it from other law firms with which we have previously worked is its great dynamism and full-time availability to attend to our affairs, as well as its’ mix of established and younger partners. The relationship with NTMA began through a personal bond with Oscar Martínez who I consider a friend. He is truly a top-notch professional both technically and commercially. He is a person who perfectly understands our needs and our business, a fact that he collaborates a lot so that we can work as a team. Likewise, it is worth highlighting the work of Juan Sabia and Felipe Martínez, who attend and manage the day-to-day operations of all the consultations we make and who handle almost all of the litigation that we have in process. They are both truly excellent and they are responsible for ensuring that the relationship with NTMA has grown to the level it is today. Finally, it is also worth mentioning Valentín Martínez with whom we work on more specific issues and he has always responded exceptionally.’
