Same-sex marriage is now legal in Northern Ireland, sparking concern among religious and conservative leaders in the Christian-majority country.
As of Jan. 13, same-sex couples are able to register to marry in the country, and those who are already married will have their union recognized by law, according to the BBC.
Those who already have civil partnerships are not able to convert to a marriage.
The move marks the implementation of legislation passed through Westminster last year, which legalized both abortion and gay marriage. The implementation of the legislation brings the province in line with the rest of the United Kingdom, where gay marriage has been legal since 2014.
