Same-sex marriage became legal in Denmark on 15 June 2012. The bill for legalization, introduced by the government of Helle Thorning-Schmidt, was approved by the Folketing on 7 June 2012 and received Royal Assent on 12 June 2012. Same-sex couples were previously recognized through registered partnerships. Denmark was the eleventh country in the world to legalize same-sex marriage.
The status of marriage is different in Denmark's two constituent countries:
Registered partnerships (Danish: registreret partnerskab) in Denmark were created by a law enacted on 7 June 1989, the world's first such law, and came into force on 1 October 1989. Three attempts to expand the law in May 2003, another in June 2003, and another in June 2006 failed in Parliament. The law was successfully expanded in June 2009 and May 2010.
Registered partnerships had almost all the same qualities as marriage. All legal and fiscal rights and obligations were like those of opposite-sex marriage, with the following two exceptions:
Divorce for registered partners followed the same rules as opposite-sex divorces. Registered partners had to meet one of the following residency requirements to form a union: (1) one partner had to be a Danish citizen and be resident in Denmark, or (2) both parties must have been resident in Denmark for two years. Citizens of Finland, Iceland, and Norway were treated as Danish citizens for purposes of the residency requirements. Additionally, the justice minister could order that a citizen of any other country with a registered partnership law similar to Denmark's be treated as a citizen of Denmark.
In 2006, lesbian individuals and couples were given the right to have access to artificial insemination treatment.
On 17 March 2009, the Folketing introduced a bill that gave same-sex couples in registered partnerships the right to adopt jointly. This bill was approved on 4 May 2010 and took effect on 1 July 2010.
