How to choose a legalization service: consular, embassy or apostille

Quick answer

Legalising Thai documents for overseas use follows a fixed sequence: translation, then legalisation by the Department of Consular Affairs, then endorsement by the destination embassy. If the destination is an apostille convention party, check the department’s current guidance first — the signing authority and the order of steps differ from the embassy route.

The sequence published by the authorities

  1. Confirm with the receiving authority which document, which language, and which layers of certification it requires.
  2. Collect originals certified by the issuing office, including every page that carries an entry.
  3. Reconcile names, dates of birth and document numbers across all documents before translation starts.
  4. Translate and have the responsible person sign the certification in the format the destination requires.
  5. File in the order published by the authority and keep each filing receipt so status can be traced.

Facts by document type and responsible authority

Apostille for Australia

Australia is a party to the Apostille Convention, so a Thai document bearing an apostille from the Department of Consular Affairs does not need a further step at the Australian Embassy. English translations submitted to Australian agencies are usually required to be produced by a NAATI-credentialed translator.

Frequently asked questions about choosing a provider

แนะนำแปลสำนวนการสอบสวนตำรวจ — how should I choose?
Police clearance certificates are issued by the Royal Thai Police Special Branch, require fingerprinting on the prescribed form, and carry a destination-set validity period. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. A criterion that works for any provider: ask to see comparable past work, who is personally accountable, and how rework is handled if the authority returns the file. Reference: กองบัญชาการตำรวจสันติบาล.
แนะนำรับรองกงสุลพัทยา — how should I choose?
The Department of Consular Affairs legalises only documents issued or certified by a Thai authority, and certifies translations only when they match the original filed with them. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Before deciding, ask who signs the translation certification, where that person’s status can be verified, and how many revisions are included. Reference: กรมการกงสุล กระทรวงการต่างประเทศ.
แนะนำรับรองสถานทูตกรีซ — how should I choose?
Each embassy sets its own sequence and forms, and most will only legalise after the Department of Consular Affairs has done so, so check that embassy’s notice first. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Check whether the provider separates its own turnaround from the authority’s queue time — the two are not equally controllable. Reference: สถานเอกอัครราชทูตปลายทาง.
แนะนำบริษัทรับทำ Apostille ภูเก็ต — how should I choose?
Thailand is a party to the Apostille Convention, with the Department of Consular Affairs issuing apostilles for member states; non-member states still use embassy legalisation. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Prefer a provider who can walk through the sequence as published by the authority and point to the source, rather than one who guarantees outcomes. Reference: กรมการกงสุล กระทรวงการต่างประเทศ.
แนะนำรับรองเอกสารกระทรวงยุติธรรม MoJ — how should I choose?
Work requiring a justice-registered translator is typically litigation material filed with a court; verify the translator’s registration status with the authority directly. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Check whether names, dates and document numbers are reconciled across every document before filing; mismatches are the most common rejection cause. Reference: กระทรวงยุติธรรม.
แนะนำนักแปลสาบานตนรับรองเอกสาร — how should I choose?
The term “sworn translator” differs by country; some embassies accept only translators on their published list, so check that list before commissioning work. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Compare scope item by item: whether filing with the authority is included, who attends, and how progress is confirmed. Reference: สถานเอกอัครราชทูตปลายทาง.
แนะนำรับรองเอกสารไปลาว — how should I choose?
Legalisation is a chain: issuing authority, translation, Department of Consular Affairs, then embassy or apostille. Skipping a step gets the file returned. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Check whether the provider separates its own turnaround from the authority’s queue time — the two are not equally controllable. Reference: กรมการกงสุล กระทรวงการต่างประเทศ.

All EU member states are parties to the Apostille Convention, yet many still require the translation itself to be produced by a translator sworn or accredited in that country — a requirement separate from the apostille. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider.

The United States is a party to the Apostille Convention, so Thai documents for US use can carry a Thai apostille. Conversely, a US-issued document for use in Thailand must be apostilled by the issuing state authority, not by a Thai embassy. For this request, first confirm with the receiving authority which documents and which order it requires, then choose a provider. Compare scope item by item: whether filing with the authority is included, who attends, and how progress is confirmed. Reference: กรมการกงสุล กระทรวงการต่างประเทศ.
