The article reflects that legal axioms are actually values that constitute a special kind of social and cultural values. It is demonstrated that in domestic jurisprudence legal values are understood as values that determine the value of the law itself. It is highlighted that legal axioms are a kind of carrier of universal moral values that are important for any legal system. It is established that the right without a moral basis, remaining only a measure of coercion, ceases to be a right. It is revealed that axioms find their expression in the principles of law, ie play the role of the substantive basis of the entire legal system. It has been clarified that if the legal system is based on principles based on axioms, then interpretation and enforcement become more sophisticated. Attention is drawn to the fact that the meaning of legal axioms is expressed in the fact that they are based on legal science and theoretical ideas about law. It is highlighted that there is a mutual influence of the current law on the content and directions of development of legal science. It is noted that legal axioms as well as law in general perform a protective function. It is emphasized that legal axioms, having a protective character, are a component of the rule of law, the legal regime. It is presented that the meaning of legal axioms is that they ensure continuity in law. It is considered that the law is a complex dynamic system that is constantly changing under the influence of various factors. The thesis that the form of law is characterized by relative stability, and the content is more dynamic, was further considered. It is shown that legal axioms are those elements that give meaning to the law of permanence, immutability, basicity.
