The construction of computer programs for citizens who will live (in the future) in Smart Cities allows to propose some legal tools and theories that are necessary in such construction. The paper presents some reflections on these resources from the experience developed in the City 2.020 (Ciudad 2.020) project that builds the relevant services and programs to be used by citizens in that kind of city. This is a city where citizens and political representative want to reach the standards of quality of life, efficiency and sustainability, which should prevail in the cities of the 21st century attending to the rules established by approved policies and laws in all the world in that respect. It is possible to say that the project develops and puts into action a model of the sustainable intelligent city, which involves programming or applications that are part of the respective services learned from the behavior of its users: citizens. It is, therefore, essential that these programs have modules that extract from their use by citizens legal behavior models, integrated and reusable in new developments. The paper exposes the role that the theory of law must satisfy in the construction of these modules.
