Apostille / Legalisation for Overseas Use packages
An Apostille is the certificate defined by the 1961 Hague Convention. Between member states it replaces embassy attestation. Thailand is a party to the Convention, with the Department of Consular Affairs acting as the Competent Authority.

Cautions from real casework
• An Apostille works only between Convention parties; presenting one to a non-member state achieves nothing.
• An Apostille authenticates the origin of the signature and seal, not the content or the translation.
• Every document must spell your name exactly as in your passport. If the spelling differs, attach the name-change certificate or a transliteration note.
• Torn, corrected or copy-of-a-copy originals are commonly rejected at the legalisation stage — request a freshly issued copy from the issuing authority first.
• Some documents carry a validity window (often 3–6 months from issue) set by the receiving authority. Check it before starting the chain.
• The order cannot be swapped: translate → certify → legalise → embassy. Skipping a step means restarting the whole chain.
Consultant tips
• Scan every original to a 300 dpi colour PDF before sending it out, in case you must refile or the destination asks for a soft copy.
• Always prepare two sets — one to submit, one to keep. Many authorities retain the submitted originals.
• If the documents will be used in more than one country, say so up front: the number of sets and the attestation format differ by destination.
• Leave at least two weeks' buffer before your real deadline: Thai public holidays and embassy holidays do not coincide.
• Keep every receipt and acknowledgement slip — they are what lets you trace the file or request a replacement if it is lost.
The full working process
The Apostille issues in about 3–5 business days once the underlying document is ready · add one business day when notarial certification is needed first
1. Check whether the destination is a Convention party
If it is a party, take the Apostille route; if not, take legalisation plus embassy attestation.
2. Get the source document into 'public document' form
Private documents must first have signatures certified by a Notarial Services Attorney before an Apostille can attach.
3. Translate as the destination requires
Some countries accept a Thai-made translation; others insist on a sworn translator in their own jurisdiction.
4. File for the Apostille at the Department of Consular Affairs
The Department verifies the underlying signature and seal, then issues the Apostille certificate attached to the document.
5. Verify the details on the Apostille
Check the underlying signatory's name, capacity, authority, certificate number and date against the main document.
6. Deliver and archive a digital copy
Many countries offer online Apostille verification, so record the certificate number for reference.

Tell us the authority and purpose up front. We shape the translation layout and the order of certifications to that requirement instead of producing a generic set and reworking it later.
