Liechtenstein's Parliament has passed a registered-partnership law that will take effect in September.
The tiny European nation is between Switzerland and Austria.
All political parties supported the law, which could be, but probably will not be, subjected to a voter referendum, activist groups said.
Same-sex couples registered under the law will have the same rights as married people except in areas such as second-parent adoption, artificial insemination and surrogacy, according to the European Region of the International Lesbian, Gay, Bisexual, Trans and Intersex Association.
