Аннотация: (English) In the era of growing globalization and international relations, foreign law and the application of international treaties assume special significance for national legal systems. This article will analyze in detail the legislative regulation of notarial acts in Ukraine with respect to foreign jurisdictions. The urgency of writing this paper arises not only from global trends toward erasing legal boundaries but also from unprecedented challenges posed by martial law, which has led to a mass movement of Ukrainian citizens and a sharp increase in cross-border legal relationships. An overview will therefore be provided regarding the relevant national legislative framework, more specifically about some important provisions under the Law of Ukraine "On Notariate" and under the Law of Ukraine "On International Treaties. It overviews, typifies, and profoundly analyses the principal types of international agreements that apply to notaries' work, with special emphasis placed on bilateral treaties on legal assistance and consular conventions. There are highlighted problem areas of existing law enforcement practice due to the absence of a standing order for international acts and difficulties in their implementation under present-day conditions. In conclusion, findings are formulated regarding the need to systematize existing international instruments, develop a unified approach to the conclusion of new treaties, and adapt notarial activities to the digital transformation for the effective protection of the rights and interests of individuals and legal entities. This article will be useful for notaries and legal practitioners specializing in private international law and cross-border transactions, as well as for employees of consulates and ministries.
