The concept of habitual residence is the most critical connecting factor in international family law. This article examines the interpretation of habitual residence under the Hague Conventions and the EU Brussels II-bis Regulation, the jurisprudence of the CJEU and the UK Supreme Court, and its reflections in Turkish practice.
In international family law, "habitual residence" is the fundamental connecting factor that determines which state has jurisdiction over decisions concerning the child, which law applies, and how decisions rendered are to be recognised. Key instruments such as the 1980 Hague Child Abduction Convention, the 1996 Hague Child Protection Convention, the 2007 Hague Maintenance Convention, and the EU Brussels II-bis Regulation are all built upon the concept of habitual residence. However, the definition of the concept is not contained in any international instrument; its content has been shaped largely through case law.
1. The Legal Significance of the Habitual Residence Concept
Habitual residence refers to the continuous and stable centre of a person's life. Unlike the concept of domicile, habitual residence reflects a factual situation rather than a legal connection. When a child is concerned, the concept becomes even more sensitive: as the child lacks the capacity to exercise independent will, the child's habitual residence is essentially determined by reference to the family environment, educational status, social integration, and the stability of daily life. This concept seeks to answer not the question "who the child is" but rather "where the child's life is centred."
2. Habitual Residence in the Hague Conventions
The 1980 Hague Convention uses the concept of the "child's habitual residence immediately before the wrongful removal" as the fundamental legal anchor of return proceedings. The jurisdictional rules of the 1996 Hague Convention (Article 5) are based on the child's habitual residence, while the 2007 Hague Maintenance Convention adopts the creditor's habitual residence as the connecting factor. The interpretive guides of the Hague Conference emphasise that habitual residence is a "factual" concept that must be evaluated according to the unique circumstances of each case. There is no single formula; a comprehensive, holistic assessment is required.
3. Habitual Residence in CJEU Jurisprudence: Mercredi and Beyond
The Court of Justice of the European Union (CJEU) has developed an autonomous interpretation of the habitual residence concept within the framework of the Brussels II-bis Regulation. In A v. Council, C-523/07 and Mercredi v. Chaffe, C-497/10, the CJEU enumerated the elements to be considered in determining habitual residence: the continuity and regularity of the child's physical presence, the reasons and circumstances of the move, knowledge of the language, school attendance, family and social relations, and the parents' intention. The CJEU has accepted that for very young children (particularly infants), habitual residence will essentially coincide with that of the primary caregiver (usually the mother). In OL v. PQ, C-111/17, the Court emphasised that mere intention is insufficient and that the factual situation is determinative.
4. The Brussels II-bis Regulation and Brussels II-ter (2019/1111)
The EU Brussels II-bis Regulation (2201/2003) introduced rules on jurisdiction, recognition, and enforcement among EU member states in matters of custody, divorce, and international child abduction. The Regulation confers jurisdiction on the courts of the member state of the child's habitual residence (Article 8). The Brussels II-ter Regulation (2019/1111), applicable since 1 August 2022, has modernised this framework, strengthened the child's right to be heard, and expedited the return procedure. Brussels II-ter operates in harmony with the 1980 Hague Convention and subjects the return procedure within the EU to stricter conditions.
5. UK Supreme Court Jurisprudence: Re A and Re B
In post-Brexit England, where the EU Regulations no longer apply, the concept of habitual residence nevertheless retains its central importance within the framework of the Hague Conventions. The UK Supreme Court has adopted the criterion of "the degree of the child's integration into a social and family environment" in determining habitual residence in A v. A (Children: Habitual Residence) [2013] UKSC 60 and Re B (A Child) [2016] UKSC 4. In Re B, Lord Wilson emphasised that habitual residence is answered not by the question "where the child's heart is" but rather by the question "where the child's life is centred." This approach is largely consistent with CJEU jurisprudence.
6. Reflections in Turkish Practice
Turkish family courts apply the concept of habitual residence in Hague return proceedings under Law No. 5717; however, the jurisprudence of the Turkish Court of Cassation on this issue lags behind international developments. In Court of Cassation decisions, habitual residence is sometimes confused with domicile, and administrative records are taken as the basis rather than the factual situation. Yet, under the principle of autonomous interpretation of the Convention, international case law should be guiding in the determination of habitual residence. Familiarity of Turkish legal practitioners with CJEU and UK Supreme Court jurisprudence is of decisive importance both in developing defence strategies and in ensuring Turkish courts' alignment with international standards.
7. Conclusion and Practical Recommendations
The concept of habitual residence is a technically appearing yet highly consequential connecting factor in international family law. The correct determination of this concept directly affects the outcome of return proceedings, the jurisdictional fate of custody disputes, and the effectiveness of cross-border protection measures. In cross-border family disputes, documenting objective elements of the child's life centre (school records, health files, social environment), establishing parental intention through concrete evidence, and preparing arguments consistent with international case law are of paramount importance.
