Marrying abroad: what governs it, and what you end up holding

gov.uk frames it as a local-law question first: whether you can get married or register a civil partnership in your chosen country depends on local laws, and it lists the common blockers — you or your partner are not nationals of the country or do not meet residency requirements, or you want a same-sex marriage or civil partnership where that is not recognised. One conversion rule is stated flatly on the same guide: you may be able to convert a UK same-sex civil partnership into a marriage in some countries abroad, but you cannot convert an opposite-sex civil partnership into a marriage abroad.

Per the same guidance, in some countries you may be able to marry or register a civil partnership at a British embassy, consulate or high commission — what gov.uk calls a consular marriage or consular civil partnership. It is not universal: the guide directs you to check which countries offer it and the processes to follow, because host-country recognition is what makes the route available in the first place. The guide's own steps also cover getting proof that you are free to marry, which most foreign registrars ask for before they will book anything.

Whichever route you take, the operative document is the certificate issued where the marriage happened — the gov.uk guide carries a dedicated step for getting your marriage or civil partnership certificate. The work usually starts after the wedding: to use that certificate in a third country, expect the same chain every foreign document runs — legalisation and, where the language differs, a sworn translation. Between EU countries, check first whether the apostille is waived, because marriage is one of the covered areas.
