Order Apostille Certification — send the file, we handle the rest
Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026; the Convention enters into force for Thailand on 28 February 2027. Until then Thai documents still require MFA legalisation plus destination-embassy attestation.
If you would rather not deal with the counters yourself, send photos of your documents first. We confirm the exact document set, the certification route the receiving authority accepts, and a realistic timeline before any work begins.

What sets the pace on this service
| Stage | Who acts | What sets the pace |
|---|---|---|
| 1. Case assessment and document check | Our team + client | Starts as soon as complete copies arrive; duration depends on how complete the Apostille Certification file is. |
| 2. Prepare translations and supporting papers | Translator + second reviewer | Depends on page count and terminology complexity; rush scheduling is possible. |
| 3. Filing with the authority | Our team ↔ the relevant authority | Governed by the relevant authority's queue and discretion at the time, so we do not promise a fixed completion date. |
| 4. Follow-up and handling objections | Our team | If more documents or corrections are requested we refile continuously rather than restarting the process. |
| 5. Final check and delivery | Our team + client | Verified before forwarding, with a complete archived set kept for future filings. |
Where files get rejected — and how we prevent it
- Relying on claims that Thailand is already bound in 2026 and planning on that basis
- Translating before the latest original is issued, forcing a re-translation
- The document is older than the receiving authority accepts
- The destination requires its own official language, not English
- Not keeping colour copies at each stage, making loss recovery difficult

Advisers, not just a processing vendor
Our team has advised on cross-border document work for over 15 years. Before any filing we tell you which document set the receiving authority actually accepts, which certification route fits, and where a faster lawful alternative exists. If a case should not proceed as planned, we say so and propose what will work.
We do not simply process paperwork — we advise throughout the case. With more than 15 years of experience we review your documents before anything is filed, flag where rejection risk sits, and sequence the full chain end to end. If you would rather not run the process yourself, send the documents for a no-obligation review first.

What are the end-to-end steps for Apostille?
We review the facts and source documents, assemble and verify the file, submit to the Department of Consular Affairs, follow up on official queries, and hand over the result with a full copy set. For Apostille a case manager tracks every stage and reports status. Call +66 83-249-4999 · LINE @NYCLI · nyclegal@ilc.ltd
Which documents are required for Apostille?
The baseline set is your ID or passport, the original documents relating to Apostille, proof of connection (house registration, company affidavit or the underlying contract) and a power of attorney if a representative attends. The exact list follows the Department of Consular Affairs requirements on the filing date; we send a case-specific checklist first.
How long does Apostille take?
Turnaround depends on the Department of Consular Affairs queue, how complete the file is, and public holidays. We give a case-specific estimate after reviewing the actual documents and update it if anything changes — do not plan travel around generic figures found online for Apostille.
What costs are involved in Apostille?
Costs split into official fees at the published government rate and our professional fee. Fees are quoted case by case based on complexity and document volume — ask our team before work starts. For Apostille we confirm the cost breakdown in writing before work starts, so nothing is added mid-way.
Who is eligible to apply for Apostille?
Eligibility is set by the Department of Consular Affairs rules and generally turns on your personal status, your connection to the document or matter, and valid identification. Applicants abroad can usually act through a power of attorney. We confirm eligibility for Apostille before any filing.
Can Apostille be handled while I am overseas?
In many cases yes, through a power of attorney certified in the form required where you live; some documents must additionally pass a Thai embassy before use in Thailand. Only steps that legally require personal appearance cannot be delegated. We sequence Apostille to minimise travel.
