Definition essence and model in Legal concepts

Although definitions is one of the main topics discussed in logic and talked a lot about it, but there is no comprehensive discussion in Etebari Sciences like law. It is because the definition of the concept and topics in the world of law, jurisprudence and the ethics is based on prior understanding of Etebar. In the world of law we deal with value concepts that on their definition we use descriptive statements (although in fact there is no describing here) and on the other hand deal with concepts or command that is used in statements such as must, haven’t to and can. Our presuppose is that we can achieve the definition of legal concepts. In this article we will look at some general theories the base of that we can be achieved the definition model of the legal concept. We want to present the definition model in law so that legal concepts can be expressed in this form.
