Recognition of same-sex unions in the British Overseas Territories

In the Sovereign Base Areas of Akrotiri and Dhekelia, only British military and civilian personnel can enter into same-sex marriages and civil partnerships.

[4] In July 2022, Labour Party Peer Lord Michael Cashman introduced a private member's bill in the House of Lords that would compel governors of each of the six British Overseas Territories where same-sex marriage is not currently legal (Anguilla, Bermuda, British Virgin Islands, Cayman Islands, Montserrat, and Turks and Caicos) to pass laws legalizing it.

The territories are also bound by the European Convention on Human Rights to pass laws legalizing some form of same-sex union, although to date only Bermuda and Cayman Islands have done so.

[24][25] On 23 February 2017, after consultation with the Governor of Saint Helena, the Tristan da Cunha Island Council agreed that a law to legalise same-sex marriage would go forward formally for adoption.

[26] An ordinance extending the Ascension Island same-sex marriage law to Tristan da Cunha went into effect on 4 August 2017 after being published in the government gazette on the same day.
