In-depth Questions Clients Ask Most

These are the most frequent questions clients in Thailand ask before booking Apostille Document. Each answer is reviewed quarterly by our editorial team against current Lawyers Council, MFA, and embassy guidance, so the dates, fees, and process windows on this page stay accurate.

How long does Apostille Document typically take for clients in Thailand?
Standard turnaround is 1–2 business days for the notary stage, plus 2–3 days at the Ministry of Foreign Affairs and 1–7 days at the destination embassy depending on the mission. Express handling can compress the full chain into 24–48 hours for clients with a verified visa appointment or court hearing.
Can the documents be used outside Thailand without further legalisation?
Documents notarised in Thailand are accepted abroad only after the chain — Notary → MFA → Embassy or Apostille — is complete for the destination country. Since Thailand's Hague Apostille membership took effect on 28 February 2027, a single Apostille now replaces embassy legalisation for member states such as the US, UK, Japan, Korea, Germany, France, Australia, and 100+ others.
What identification documents must I bring to the appointment?
For Thai nationals: national ID card plus the original document. For foreigners: passport plus a valid Thai visa or entry stamp. Corporate clients should bring the company affidavit (DBD), the authorised signatory's ID, and the company seal if used in the document.
Do you provide certified translations alongside the notary service?
Yes. NAATI-credentialed translators (English, Chinese, Japanese, Korean, German, French, Spanish, Arabic) work in-house, so the translated version can be notarised the same day. This avoids the common delay of bouncing between a translation vendor and a notary office.
What is your refund or rebooking policy?
If the document is rejected by the MFA or destination embassy due to an error on our side, we re-process at no charge and refund all MFA / embassy fees. If the rejection is due to client-provided information (e.g. spelling or missing supporting documents), we offer a 50% rebooking discount.

Pre-Submission Compliance Checklist (12-Point)

Before we file your Apostille Document with the MFA or any embassy, every case passes a 12-point checklist. This is the same checklist used internally by our senior counsel during the final QA step.

  1. 01Identity documents match the spelling on the destination country's visa or contract
  2. 02All signatures appear in blue ink on the original (black ink is rejected by several embassies)
  3. 03Date format matches destination country convention (DD/MM/YYYY vs MM/DD/YYYY)
  4. 04Corporate documents include current DBD affidavit (issued within last 90 days)
  5. 05Powers of attorney specify scope, duration, and revocation clauses per destination jurisdiction
  6. 06Educational transcripts bear original university seal, not photocopy
  7. 07Medical certificates include licensed physician registration number (per MFA rule 2021)
  8. 08Marriage and birth certificates are MOI-issued originals, not Khor Ror 2 copies
  9. 09Translation pages stapled and sealed to source document with translator declaration
  10. 10Stamp duty (where required) affixed before notarisation, not after
  11. 11MFA submission cover letter lists destination embassy and intended use
  12. 12Tracking number registered in our CRM and shared with client via LINE @NYC168
