Same-sex couple Mima Simic and Marta Sisak walk hand in hand in Zagreb's downtown November 26, 2013. Croats voted in a referendum on Sunday to determine if marriage as a "union of man and woman" should be enshrined in the constitution, a move initiated by Roman Catholic groups and criticized as discriminatory by opponents. In Croatia, gay pride marches have become routine but same-sex partners still face many practical challenges. According to Susak, at present, she's unable to inherit her girlfriend's property, adopt children together, get married or even visit her if she ends up in an old people's home.
