Abstract: Although the formalization of legal documents is quite useful, they contain various kinds of if-then relations. In this paper, we aim at formalizing the prerequisite-effect structure in temporal/causal settings. We regard the progress of time as hereditary accessibility in temporal states, and thus we introduce Kripke semantics. Our ultimate objective is to construct a legal reasoning system, however, since those various kinds of logical relations may complicate the reasoning system we avoid to introduce multiple modal operators. We stay in simple intuitionistic logic, and we will extend it to include the prerequisite-effect structure. Then, the structure is defined in the augmentation of known facts, that is, the effect is immediately follows after the prerequisite is satisfied.
