This book investigates the procedural mechanisms and judicial standards governing the application of foreign law within domestic civil litigation systems. Sofie Geeroms, an expert in private international law, examines the tension between national sovereignty and the necessity of incorporating foreign legal norms. By analyzing the evidentiary and procedural hurdles courts face when identifying and applying foreign statutes, the author argues that the treatment of foreign law serves as a barometer for a legal system's openness to international integration.

Legal scholars and practitioners identify this work as a foundational text for understanding the intersection of procedural law and private international law. Readers frequently note the academic density of the prose, which makes it a primary resource for researchers focusing on comparative civil procedure.
