Same-sex couples do not, however, have the right to register under Hungary's marriage law. Iceland's law is similar to Denmark's, allowing same-sex couples to register their partnerships in order to receive many of the rights of marriage, but registered couples cannot adopt children. Pisa and Florence allow same-sex couples to register as domestic partners. This country, too, has a nationwide partner registration law. Registered same-sex couples receive all the rights of heterosexual married couples, including pension, social security and inheritance rights.
Work is underway to simply amend the marriage laws to include same-sex couples without restrictions.
Registered partnerships are available. Many cities allow same-sex couples to register as domestic partners. Also, a nationwide law allows a widowed partner to remain in rental housing when only the deceased signed the lease. Spain is expected to take up the issue of nationwide registered partnerships by the end of the century. Sweden's law is similar to Denmark's, allowing same-sex couples to register their partnerships in order to receive many of the rights of marriage, but registered couples cannot adopt children.
