Implications of the Principle of Complementarity in International Private Relations A Comparative Study

Abstract

Abstract: The principle of complementarity in legal jurisdiction is reflected in the fundamental concepts of private international law. This interaction between national and international laws reflects and integrates to ensure the achievement of justice and the efficient resolution of international disputes within the legal jurisdictions that define the nature of these international legal actions.

In cases of conflict of laws and international jurisdiction, and extending to the enforcement of foreign judgments, different legal systems work in a complementary manner to determine the applicable law or the competent court, particularly in matters related to personal status, international contracts, civil liability, and other legal actions with international reach.

It contributes to strengthening judicial cooperation between states through mutual recognition and enforcement of legal rulings, which reduces legal contradictions and provides effective solutions for individuals and companies in the context of globalization.

Its role in achieving a balance between state sovereignty and the need to create flexible legal mechanisms to address cross-border disputes makes it an essential element in the development of private international law and ensuring the achievement of justice in a multi-systemic and interdependent legal environment. It also seeks to find legal formulas for global complementarity to achieve balance at the level of international private relations.
