On March 12, 2026, the Court of Justice of the European Union (CJEU) ruled that EU member states must ensure that individuals can obtain official documents reflecting their gender identity where necessary to safeguard the effective exercise of European Union (EU) free movement rights.

The case concerned a Bulgarian national who was registered as male at birth but “always felt like a woman.” After moving to Italy, the applicant—who had undergone medical consultations and hormone treatment—faced practical difficulties in daily life due to the discrepancy between her appearance and the sex indicated on her Bulgarian identity documents. She therefore sought to have her female gender identity recognized in official Bulgarian records. Bulgarian authorities, including the Supreme Court of Cassation, refused, citing national law.

Citing Article 21 of the Treaty on the Functioning of the European Union and Directive 2004/38 on the right of EU citizens to move and reside freely, the Court held that discrepancies between a person’s gender identity and the gender indicated in official documents may create “serious inconvenience” in everyday life, particularly in cross-border situations. Such discrepancies, the Court found, are capable of hindering the exercise of the right to move and reside freely within the EU. 

The Court reaffirmed that civil status falls within the competence of member states but emphasized that national authorities must exercise that competence consistently with EU law. In particular, member states may be required to provide mechanisms enabling individuals to obtain identity documents consistent with their gender identity where failure to do so would undermine the effectiveness of EU citizenship rights.

The decision builds on earlier CJEU case law addressing gender reassignment and non-discrimination, including P v S and Cornwall County Council, and seems to form part of a broader line of jurisprudence linking personal status to the effective enjoyment of EU citizenship. It also follows recent developments concerning the rectification of gender-related data in national registers under EU law. The Court had already held that a member state must recognize and give effect to a change of gender and name lawfully acquired in another Member State where refusal would create discrepancies in civil status documents and thereby hinder the exercise of EU free movement rights.

The ruling does not harmonize national laws on gender recognition across EU member states. It does, however, require member states to ensure that individuals can obtain documentation consistent with their gender identity where inconsistencies would interfere with free movement. More broadly, the judgment reinforces an approach under which EU law requires the functional recognition of personal status across borders, while leaving the underlying substantive rules largely within national competence.
