The matters of evading the law are, usually, imperative norms that impose certain ways of behavior and exclude a possibility of the parties to regulate their relationships through an agreement. For the sake of regulative security and providing legal effect of civil-legal relationship in foreign countries, it is recommended that the national court or the administrative authority, if there is a suspicion that some parties try to evade the foreign law, stop the process until the matter is not solved. After receiving a notification from a foreign organ on the procedure in international legal aid regarding this matter, the process may continue and a decision can be brought up depending on positive or negative answer. Specificity of evading the law consists in formal and legal proceeding of a client according to the letter of the law, but against the spirit of the law. If we add the fact that this is the matter for a foreign country and that application of different legal systems may be applied, we get an international dimension and a possibility of viewing the problem of fraus legis as a complex problem.
