The article is devoted to the application of some temporal systems, and especially of their language, in the legal sciences, mainly in the area of dogmatic law. The first part sets out the conditions that have to be satisfied by temporal systems in order to be applicable in these sciences. The second presents a short characterization of some tense logic systems and von Wright's And Then system. The third part contains examples of their application in the legal sciences. The article maintains that suitable temporal systems can provide a precise language by means of which one can formalize the propositions of legal language that contain specific tense expressions and create models for inferences that contain such propositions. The appropriate systems would also provide tools for checking the correctness of these inferences.
