J.L. Casajuana was born as a law firm in 1976, founded by our managing partner José Luis Casajuana Espinosa. Since then we have been offering our services to companies and individuals, in the field of national and international legal advice, in defense before courts and in arbitration proceedings.

Throughout these 40 years we have maintained the most demanding professional standards. But we have also understood the new needs that have emerged in recent times. The client has always required the close treatment of his trusted lawyer, but now he also requires a specialized lawyer for each problem, with training and experience in a specific legal area.

The evolution of our office has been accompanied by these new criteria. At present we have differentiated departments depending on the subject, composed of expert lawyers in each branch of Law.

We want to distinguish ourselves by providing quality services, based on personal treatment and permanent communication. Objectives that we achieve through specialization in each of the departments, attended by qualified professionals and experts, which allow the analysis of all aspects of the case raised and the coordination of the measures to be applied.

The secret of our success lies in having managed to combine the experience of a traditional office, with the modern organization of a specialized team and a balanced structure that allows us to offer a personalized service with the best value for money in the market.

J.L. Casajuana is the founder of a network of law firms in Spain that acts in coordination to offer a quality legal service.

It is an initiative of our Office, which arises in response to the need of our customers to intervene immediately in different areas of the national geography. The permanent collaboration of its members constitutes an added value to fulfill our commitments of punctuality and effectiveness.

The network has offices in all provinces and autonomous communities, which allows us to take urgent action without delay despite the distances.

The law firms that, like J.L. Casajuana, make up this network, offer national and foreign clients a unitary treatment before any judicial or extrajudicial problems.

Particularly, our Office has a special emotional and professional relationship with the Autonomous Community of Castilla La Mancha, where we have a large portfolio of clients. Therefore, we maintain a stable collaboration with Perales Casajuana Abogados, based in this Community, where both offices offer our services in a coordinated manner.

J.L. Casajuana has the honor of being part of a network of prestigious law firms with implantation in various countries that has similar profiles of quality and experience. The network has offices in important and strategic cities from a commercial and legal point of view.

Many of our clients require international legal advice, in which regulations and regulations of different countries must be confronted. There are legal proceedings involving more than one country that require prior legal analysis in different countries. And even it is frequent that the commercial relations of businessmen, manufacturers, importers or wholesalers need the knowledge of several national regulations.

Through the offices of this network we can give advice on foreign legislation quickly. And have the legal opinion of top legal experts.

This integration allows us to meet the needs of our customers for actions outside our borders, without displacement or communication difficulties.
