Must both Kor Ror 2 and Kor Ror 3 be translated?

It depends on the destination — some accept the certificate alone, others also want the register entry. Ask first.

Can an apostille be used instead yet?

Check the Department of Consular Affairs’ announcements and the entry-into-force status each time; until it applies, use the ordinary legalisation chain.

How long does the certified set stay valid?

Thailand does not set a general expiry, but receiving bodies often do, so ask the destination.

Thai marriage certificate with its English translation

Using a Thai marriage certificate abroad — certified copies, translation and the legalisation chain

Quick answer

Start with a registrar-certified copy of the marriage record from the district office, prepare a translation into the destination language, then have the original and translation legalised by the Department of Consular Affairs. In many cases the receiving country also requires a further step at its embassy in Thailand. The final criteria are always set by the body receiving the document.

Key facts and the responsible authority

Using a Thai marriage certificate abroad — certified copies, translation and the legalisation chain
Which document to use	The marriage certificate (Kor Ror 3) and/or the marriage register entry (Kor Ror 2), certified by the registrar, as specified by the receiving body
Who legalises in Thailand	The Department of Consular Affairs, Ministry of Foreign Affairs
The embassy layer	Many countries require their embassy in Thailand to certify after the Department of Consular Affairs; check with that embassy directly
Thailand’s apostille position	Thailand has moved to join the Apostille Convention, but replacing legalisation with an apostille depends on the entry-into-force date and official announcements — until then use the ordinary legalisation chain
Translation language	Usually English, unless the destination requires its own official language — ask before translating
Official fees and timing	Set by each authority and subject to change, so no figures are given here

Document checklist and the certification involved

Registrar-certified copy of the marriage record
Should be a recent certified copy within any validity window the destination applies
Translation into the destination language
Submitted together with the original for legalisation
Passports of both parties
Copies, to verify name spellings used in the translation
Power of attorney if someone files on your behalf
In the form and on the conditions the receiving office requires

Step by step

Obtain the certified copy: Request a registrar-certified copy of the marriage record from the district or khet office.
Confirm the destination’s criteria: Ask the receiving authority or embassy which version, which language and which certification layers are required.
Translate and proofread: Prepare the translation and verify names, dates and document numbers against the original before filing.
Legalise, then the embassy layer: File with the Department of Consular Affairs first, then with the destination embassy if required.

What to do

Order more than one certified copy at the outset — receiving bodies usually keep the set you file.
Photograph every page of the certified set before it leaves the country.
Ask the destination about validity windows first, to avoid repeating the whole cycle.

What to avoid

Do not submit an ordinary photocopy in place of a certified copy; it will not pass legalisation.
Do not self-translate and self-certify where the destination prescribes a specific translation format.
Do not copy another country’s sequence — certification layers differ between countries.
