Agustí ­ Jausàs. Founder of JAUSAS

The majority of the medium- and large-sized Spanish law firms are the result of the unification of several firms. At Fieldfisher JAUSAS we have the honour of not being just the result of various mergers, but rather of the incorporations of renowned professionals to the same project.

Since its founding 50 years ago, the law firm has been growing as a prestigious firm thanks to the efforts and dedication of great professionals that have contributed to create the brand that Fieldfisher JAUSAS is today. Our story is told thanks to the experience of all our partners, associates, senior and junior lawyers, interns and each and all the technicians and other professionals that are part of our firm or have been part of it. All of them have contributed to lead us towards progress and growth in recognition and prestige.


The Beginning

Agustí Jausàs founded a law firm after five years of combining his work in a laboratory with an internship, to which he had been obliged to undertake to earn a living after the death of his father. The combination of both experiences was the key to his success and for years he held the exclusivity in legal services to pharmaceutical companies.

The 70's

Consolidation of international contacts

The relations of Agustí Jausàs with important foreign lawyers led him to be one of the first Spanish professionals to enter in the International Bar Association (IBA), the most important lawyer’s association on the international level. The links woven in the organization were consolidated during the decade of the 1970’s and would permit him to hold important posts. During more than eight years he served as co-chairman of the Section “Sales and Related Commercial Transactions”, the most important of the era.


The most important step

The legal market of Spain had for some time been the scenario of the creation of multidisciplinary offices. In this context, Jausàs merged with Nadal & Vidal de Llobatera, a firm dedicated to Commercial Law and Litigation. Both shared the concern of having solid contacts and alliances outside Spain in order to cover the needs of clients that were becoming increasingly international.


The JAUSAS era begins

Jausàs, Nadal & Vidal de Llobatera merged in 2003 with Foro Legal, which allowed the firm to take the qualitative step in invoicing and geographic presence on the national level. The partners decided then to keep the name of the oldest firm. The brand originated under which were grouped nearly 100 persons between our two offices and to which in these last ten years two other firms have been incorporated: March & Asociados, which joined in 2007, and A&S Sampere Abogados, which did so from 2012 to 2015. The law firm keeps its commitment to growth in order to remain among the main medium size law firms in Spain.
