Abstract

In Portugal and other countries in Europe, there is an increase in the number of couples who live together without getting married, known as de facto partnership. This is due not only to ideological and practical reasons, such as the perception that marriage is too formal or the legal impossibility of getting married in some cases. In particular, the text addresses the legal complexity of the family, focusing on the legal problems that arise in the patrimonial sphere of these de facto partnership. The regulation of the patrimonial effects of these unions varies from country to country, further complicating the situation when de facto partnership has an international context. In these cases, private international law plays an important role in determining the competent courts, the applicable law, and the recognition of decisions in other states. This article will focus on the problems that arise regarding the determination of the applicable law. For this purpose, European Regulation 2016/1104 establishes enhanced cooperation in the field of the patrimonial effects of registered unions, but leaves unregulated the patrimonial problems of unregistered couples, which continue to be governed by the national law of each member state.
