Do I need to legalize my UK divorce decree in the UK?

Yes. The Decree Absolute must be apostilled by FCDO Milton Keynes before being brought to Thailand for translation and amphur use.

Can the British Embassy issue a Certificate of No Impediment?

No. Since 2014 the embassy issues an Affirmation/Affidavit only; the Thai amphur accepts this in lieu of a CNI.

Should I use FCDO Apostille or UK Embassy legalization?

If you are already in the UK, FCDO Apostille (£30, 2 days) is cheaper. If you are in Thailand, UK Embassy Bangkok legalization is faster — no shipping needed.

Does Thailand's Apostille (since Dec 2024) replace MFA legalization?

Yes — for Hague-member receiving countries like the UK, a Thai-issued Apostille is now accepted directly. MFA legalization is the legacy path; Apostille is the new single-step.

Do UK Spouse visa documents need to be translated?

Yes. UKVI requires certified English translations of all non-English documents, including the translator's statement of competency, name, signature and date.

AI Quick Answer

How does a Thai citizen marry a United Kingdom national in Thailand?

The United Kingdom spouse obtains a Certificate of No Impediment (or equivalent affidavit) from the United Kingdom Embassy in Bangkok, has it translated into Thai and legalized by the Thai Ministry of Foreign Affairs, then registers the marriage at any Thai amphur with two witnesses. After registration, request the English Kor Ror 3 and re-legalize it via MFA for use in United Kingdom. Total time: 7-12 days.
