This casebook provides a comprehensive, accessible, and up-to-date analysis of family law from comparative and private international law perspectives. It emphasizes the need to examine complex cross-border family situations by comparing legal systems and understanding the jurisdictional overlay, with a particular focus on the United States. The casebook addresses some of the most intimate and legally complicated situations in which cross-border families find themselves, including the validity of foreign marriages, simultaneous divorce proceedings in multiple countries, the changing law in creating families using adoption and assisted reproductive technology, and how to remedy an international parental child abduction. In addition, the book dives into the importance of judicial assistance treaties and laws when understanding the legal issues, including the necessity to have proper service in a foreign country, obtaining evidence overseas, and authenticating foreign public documents. This book is a superb companion for law students and practitioners alike, and can readily be used in a traditional theory-based class and in practicum courses. It provides substantive material for a course on International Family Law, or can supplement a course on Family Law, International Law, or Comparative Law.
