Officials in Poland’s capital Warsaw announced on May 14th the first official recognition of a same-sex marriage from another EU country.  

Poland’s Supreme Administrative Court ruled in March that same-sex marriages contracted in other EU states must be recognised in Poland, incorporating a 2025 CJEU ruling in a case brought by Jakub Cupriak-Trojan and Mateusz Trojan.

However, Poland’s laws still define marriage as between a man and a woman, and the country is one of the last in Europe not to have legalised either same-sex marriage or civil unions—alongside Bulgaria, Romania, and Slovakia.

“This morning, we carried out the first transcription” of a same-sex marriage certificate, liberal Warsaw mayor Rafał Trzaskowski told the media.

Prime Minister Donald Tusk’s coalition is divided over the issue, but he had hinted on May 12th that the Warsaw municipality’s step was imminent.
