Same-sex marriage is legal in Northern Ireland as of Monday, bringing the country in line with the rest of the United Kingdom.
Same-sex marriage has been legal in England, Scotland, and Wales since 2014.
The law allows same-sex couples to register to marry, meaning that the first weddings will take place in February. It also legally recognizes those who are already married. Couples who currently have civil partnerships are not yet able to classify it as a marriage, although the Northern Ireland Office is set to begin a consultation on the matter later this year.
Heterosexual couples are now also allowed to enter into a civil union.
? Same-sex marriage was made legal in Sweden in 2009 and in Denmark in 2012. It is currently legal in 27 countries, including 16 in Europe.
