Recognized Same-sex marriage has been legal in South Georgia and the South Sandwich Islands since 13 March 2014, in accordance with the law in force in England and Wales, although the Foreign and Commonwealth Office only updated its travel advice website page to include a note about it in January 2018.
Nonetheless, a marriage between persons of the same sex was considered void ab initio in common law, and as such same-sex couples could not marry on the islands.
[8] The Government of the United Kingdom may also enact laws that are directly applicable to the territory, generally regarding matters of international relations.
Concerning matters not covered by local legislation or directly applied UK legislation, then, in accordance with the Interpretation and General Clauses Ordinance 1977, the law in force in England and Wales shall be in force in South Georgia and the South Sandwich Islands "in so far as the circumstances permit and provided they are not inconsistent with or repugnant to any Ordinance or Order in Council".
All marriages must be conducted in the vicinity of Grytviken, with the Norwegian Anglican Church being a popular location for ceremonies.
