Identity and civil-status documents
Passport, ID card, house registration, birth certificate, marriage or divorce record and single-status affidavit — the baseline set for almost every visa file, and the family most often rejected over name spelling.
Thai identity and civil-status records are issued by district registration offices under the Department of Provincial Administration. They are Thai-language documents, so a visa file abroad needs an English translation (or a translation into the destination's official language) plus legalisation by the Department of Consular Affairs before the destination embassy stage.
The most common failure is an inconsistent English spelling of the applicant's name across documents — a birth certificate translation that differs from the passport, or a married surname that does not match the current house registration. The safest rule is to follow the passport spelling and, where the source document differs, show both spellings in the translation so the officer can link the records.
Freshness matters too. Many embassies require recently issued certified extracts of registration records and status affidavits rather than older copies, so obtain new extracts before starting the translation and legalisation chain to avoid them expiring mid-process.
Foreign nationals filing inside Thailand face the mirror image: documents issued abroad must be certified in the issuing country and by that country's embassy in Thailand, or by the Royal Thai Embassy in the issuing country, before being translated into Thai and legalised for use with the Immigration Bureau or other Thai authorities.
Thailand still uses the traditional legalisation chain. The 1961 Hague Apostille Convention enters into force for Thailand on 28 February 2027, after the deposit of its instrument of accession on 30 June 2026 (source: HCCH). Until then, visa supporting documents must still pass through the Department of Consular Affairs and the destination embassy.
Supporting-document requirements vary by visa category, nationality and the embassy or consulate receiving the file, and they change over time. Always check the current checklist published by the receiving authority before you start.

Frequently asked questions
My birth certificate name differs from my passport. What should the translation say?
Use the passport spelling as the primary form and note the source-document spelling alongside it so the officer can see they refer to the same person. If the difference comes from a legal name change, attach the translated and legalised change-of-name certificate.
How long is a single-status affidavit valid?
Thai law sets no expiry, but receiving authorities usually impose their own recency rule. Check the embassy's published requirement and obtain the document as close to submission as practical.
Which comes first, the Ministry of Foreign Affairs or the embassy?
The Department of Consular Affairs always comes first. The embassy then certifies the consular officer's signature — it does not certify the content of the document itself.
Can I translate the documents myself?
Most authorities require a translation accompanied by a certificate of accuracy, and consular officers compare the translation against the original before legalising it. Self-made translations without certification usually fail at that stage.
Can Thailand issue an Apostille yet?
Not yet. The Convention enters into force for Thailand on 28 February 2027 (source: HCCH). Until then the consular plus embassy chain still applies.
