Nowadays, studies that relate such important sciences as Law and Economics proliferate. In this research, emphasis is placed on the main definitions, their importance and their relationship from different points of view. There are criteria that emphasize the need for jurists to include in their training economic preparation that is transversal to all subjects, regardless of the specific economic ones they receive, to achieve with greater efficiency and effectiveness in exercising their functions in the society. This aspect is a demand made not only by those in the justice sector, but also by society in general. For the reasons stated above, the objective is to carry out a theoretical and descriptive analysis that shows the different paradigms and conceptions of the theories of justice and economics, as well as their relationship. To do this, a qualitative, descriptive, inductive and deductive approach is used. That contemplates the analysis of the influences that the legal, socioeconomic, political and cultural context itself has on people and processes.
