The practice was founded in 1989. After first steps essentially in Environmental and Labour Law, other legal branches were progressively practiced, such as Family, Criminal, Contentious-Administrative, Civil, Mercantile and Company Law.


Today, our wide range of specialisations in numerous branches endows us with a view of the greater picture, a necessary factor in all legal disciplines, while simultaneously enabling us to treat each individual case with the rigour that it deserves.

Mercantile Law

Advising companies and defending their interests includes the formulation, revision and negotiation of contract documents. There are also questions concerning the company’s very organisation, including the incorporation of Companies, the drawing-up and reformation of their articles of association, increases or reductions in capital, the merger and absorption of Companies, the separation and exclusion of partners and a long etcetera.


Jaime Casado Ruiz has served as professor in the Master for Lawyers at the University Pablo de Olavide.

Civil Law

Civil Law occupies an important place in the Practice's activities due to the fact that most of our client's consultational needs and most of the conflicts that affect them are directly or indirectly related to this branch of the Law. Within Civil Law are issues such as Sales, Inheritances, Insurances, Urban and Rustic Property Rental, Family Law and Traffic Law.

Administrative Law

On numerous occasions conflict between citizens or companies and the Administration is the inevitable result of the different Public Administrations' increasing intervention in, and regulation of, different aspects of daily life. 

Sectors such as Town Planning, Fiscal Law, the Administration's Patrimonial Liability, Expropriations, and matters concerning internal staff relationships within the Civil Service frequently require legal advice and intervention before the Administration through administrative appeals procedures or through actions brought in the Economic-Administrative Courts or before the Contentious-Administrative Courts and Tribunals. 

In the specific field of environmental law Jaime Casado Ruiz has developed consulting work as expert for private companies, the Ministry of Foreign Affairs of Spain and the European Union.

Labour Law

We treat Labour Relations in all of their different aspects, acting as advisors, defending parties in concrete cases and also acting as negotiators on behalf of individuals or collectives.

National and International Law

The practice takes a great interest in the global dimension of legal, mercantile and human relationships in today’s world.  


International Law is both studied and applied by the Practice, as indeed is the Law of third countries, an activity we undertake generally through co-operational links established with professionals in other geographical areas.  


Our knowledge of different languages (Spanish, English, French, German) allows us to be involved in examining legal or contractual documents as well as enabling us to keep fluent channels of communication open with clients, parties and interlocutors from third countries, such channels being a prerequisite for consultations, negotiations, and legal or arbitrational actions.  


Jaime Casado Ruiz is a member of the Seville’s Bar Association’s International Relations Committee, and of the European Lawyers’ Union.
