Taiwan's Path Toward Sustainable Development Goal 5 in Private International Law

Sustainable Development Goal 5 (SDG 5) has different implications for countries. This paper explores Taiwan's path toward SDG 5 and examines the legal environment surrounding this path. Taiwan's unilateral implementation of UN conventions effectively bridges certain gaps between itself and the international community. Reforms in private international law and the legalization of same-sex marriage have further promoted gender equality from a conflict-of-laws perspective. The recognition of the exceptional validity of polygamous marriages illustrates the pursuit of justice in cross-border legal conflicts. It is observed that alternative applicable laws, ordre public , and overriding mandatory provisions serve as effective tools for states to advance SDG 5. Taiwan's traditional rules on ancestor worship associations collide not only with modern legislation on estate succession but also with foreign laws when the membership disputes involve foreign elements. This paper argues that the nature of rules on estate succession should be distinguished from that of ancestor worship or family lineage, and that SDG 5 is helpful in modernizing the local customary rules on ancestor worship associations. It further suggests that the provisions on legal persons in the Choice of Law Act 2010 may be applied by analogy to determine the governing law for the membership of unincorporated ancestor worship associations.
