The article provides a scientific and practical analysis of international legal aspects relating to the issue of determining the exclusive jurisdiction of a dispute by means of a choice of court agreement, which is quite relevant, since the ratification of the relevant Convention, which was signed in 2014, took place during the martial law regime, which complicates the process of implementing the provisions of the Convention in the Ukrainian legal system. The author analyses the current Ukrainian legislation in the area of determining the jurisdiction of private law relations with a foreign element, in particular, proceedings in cases related to the jurisdiction determination procedure, and international documents in the area of choice of court agreements, such as the Laws of Ukraine «On International Private Law», «On Amendments to Certain Legislative Acts of Ukraine in connection with the Ratification of the Convention on Choice of Court Agreements», the Hague Convention on Choice of Court Agreements and the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. The author identifies certain problems of enforcement of the choice of court agreement in the judicial system of Ukraine and issues of procedural protection of the parties to the agreement. It is noted that currently there is no definition of an exclusive choice of court agreement in national legislation and there are problems in the enforcement of a Ukrainian court decision by other states where no agreement on legal assistance has been concluded. The difficulty of applying the Convention on Choice of Court Agreements in comparison with the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards has been proven, which may lead to differences in the practice of use among the countries that are parties to the Convention. The author identifies the need to expand Article 4-1 of the Law of Ukraine «On Private International Law» and improve the implementation of disputes involving an exclusive choice of court agreement. The author emphasises the need to resolve problematic issues, as this will positively affect the international legal image of the state and prepare further legislative changes for more effective synthesis of the legal systems of Ukraine and the EU member states.
