This chapter first examines the international legal relationships that give rise to the formation of a family. It then analyzes the legal regulation of these aspects within the Colombian legal system. Subsequently, the chapter briefly discusses the relevant provisions of two proposals: the Draft General Act on Private International Law for Colombia, prepared by the Instituto Antioqueño de Derecho Internacional Privado in 2021, and the Draft Civil Code of Colombia presented by the Universidad Nacional de Colombia in 2023.
