Relevance of the topic. The sea has always been very important to the culture, identity, history and economic development of nations. The sea is both a way to transport goods and a connection with the people from other countries (Sencila, 2008). Lithuania is a maritime country. The sea has been of great importance to the life of every person since ancient times, but it was just the beginning of the interest in the ocean and that led to the legal regulation of shipping, fishing and other relations. Building the Maritime Law, as law itself, the biggest role was played by Roman law. Even Romanian people understood, that sea and air belong to everybody and could never become someone else’s property. The main problems. The Republic of Lithuania, as a subject of international maritime law, is not much studied and very broad topic. The following tasks: 1. To analyze the sea carrier’s powers and obligations, responsibilities according to the bill of lading. 2. To highlight the most relevant problems of the legal system. 3. To model a possible system efficiency strategy. The aim of the work is to investigate and evaluate the prevailing legal system in order to diagnose the problems of the system for its prognostic effectiveness. The paper concluded: The analysis of using International and Lithuania National legal acts in the situation with the strong international accent is very important in order to build a strong legal country. The novelty is that the Maritime Law is not so much investigated in Lithuania, although the contract examples can be found, but there are few analyzed court decisions highlighting the fundamental differences between Lithuania national and international law. The scientific novelty of the study lies in the fact that it is one of the several scientific works in international, based on valid international legal acts and legal acts of Republic of Lithuania. At the same time, the work focuses on insufficiently explored problems, which include both theoretical part and the analysis of international law practice in the field of control in international Maritime Law. The most important aspect is that the topic under consideration is directly related to the author’s work in logistics. It is not only a theoretical work, but also a practical one, which makes this work unique. As the result – after analyzing the court decision and legal acts of both international and national law, was concluded, that Lithuania court gives priority to national law, that do not have sense in the context of Maritime Law. The used methodology document analysis, information analysis, comparative analysis, logical – analytical methods.
