This paper is dedicated to exploring the concept of habitual residence of adults in the context of the Brussels IIa Regulation focusing on the best practices of national courts of the EU Member States. It not only offers a still rare to find examination of the application of this important EU law concept in multiple EU Member States, but also discloses some common European trends and misconceptions, thus helping to better understand the EU notion of habitual residence. The paper claims that in the absence of clear advice from the Court of Justice of the European Union as to how habitual residence of an adult is to be established for the purposes of Brussels IIa, some useful guidance can nevertheless be inferred from the national case law.

根据布鲁塞尔IIa法规建立成年人的惯常居住地：国家判例法中的最佳做法

本文致力于探讨《布鲁塞尔IIa法规》中成年人的惯常居住概念，重点关注欧盟成员国国家法院的最佳实践。它不仅为在多个欧盟成员国中应用这一重要的欧盟法律概念提供了检验的机会，而且还揭示了一些常见的欧洲趋势和误解，从而有助于更好地理解欧盟的惯常居住概念。该文件声称，在欧盟法院没有明确建议如何为布鲁塞尔IIa确立成年人的惯常居住地的情况下，仍然可以从国家判例法中推断出一些有用的指导。
