Registered partnership

Registered partnership of two persons of the same sex aged 18 or over (Act on Registered Partnerships of 9 Nov. 2001/950). Partnership is registered by an authority entitled to perform civil marriage ceremonies. Registered partnership is dissolved when one partner dies or is declared dead, or when it is dissolved by court order.

The possibility to register partnerships started in Finland on 1 March 2002 and ended on the last day of February 2017 (Act to amend the Act of Registered Partnerships 250/2016). Starting from the beginning of March 2017, same-sex couples have been able to enter into marriage (156/2015).

As a result of the amendment to the Marriage Act, parties to a partnership registered in Finland can convert their partnership into a marriage by making a joint notification of this to the Digital and Data Services Office. A registered partnership continues as a marriage from the day on which the Digital and Data Services Office has received the notification.

In the statistics, registered partnerships that have been converted into marriages based on such notification are not included as contracted marriages in the annual statistics.
