In the paper the utilization of legal expert systems for simulation is presented. Law in a general form prescribes the frame of possible behavior of players in the domain regulated by it. A law can be considered as a set of rules forming a knowledge base and problems arising in the domain of its application should be answered based on it. In the last six years we developed a method to transform rules of law as it is published in statute-books into working expert systems. On the other hand simulation is the use of models to predict behavior of existing or planned real system. If we consider the law as a model of the reality it is regulating, the corresponding expert system could be considered as the implemented version of this model on computers. Now by the use of these expert systems we can perform simulation. This simulation means the examination of the possible behavior of the players which in some cases can be quantified by the use of statistical data. The method presented is particularly useful when one is framing new laws and wants to see the possible effects of the different proposed versions. Our method is mainly applicable for tax law, social security law, Finances Act or similar laws.
