What is a civil partnership in the UK?
- Legally recognised union between a same-sex couple.
- Couples in a civil partnership receive equal legal treatment including inheritance and next-of-kin arrangements
- Partnership ceremonies can be conducted in private, whereas marriage ceremonies must be public and can be conducted by clergy
- Failed partnerships require dissolution, like divorce

France introduced the Civil Solidarity Pact or PACS to give legal status to both heterosexual and same-sex couples.
Although a PACS does not give the same rights as marriage, it is nonetheless popular with couples.

Hot on the heels of their neighbours, Belgian citizens in opposite-sex relationships have been able to choose a civil union or "statutory cohabitation" over marriage since 2000.
The French PACS model also influenced Luxembourg.

Nevertheless, the law came into force on 1 January 2016.
Isle of Man, 2016
Men and women in Britain hoping to one day have a civil partnership can be inspired by the Isle of Man, which is a British Crown Dependency.
The island passed the law in August 2016.
