“Which authority handles online 90-day reporting and what documents are required?” falls within an end-to-end service that combines document preparation, translation, signature certification, consular legalisation and coordination with the destination mission into a single file. The people who search for it are usually preparing a filing against a fixed deadline, recovering from a rejected submission and trying to identify the missed step, or coordinating documents for several people at once.
In practice, each step sits with a different body: the issuing office, the Notarial Services Attorney, the Department of Consular Affairs, and the destination country’s diplomatic mission. Knowing which body owns which step makes it possible to judge how many stages a bundle needs, and which of them cannot be corrected without starting again.
This is a baseline set. Individual receiving authorities may add requirements, so confirm with the destination body first.
Record how many stages each document needs, who certifies it, and what must finish first, so no step has to be redone.
Check personal names, company names, addresses and dates across the whole bundle before any certification begins.
Original → translation → signature certification / legalisation → destination mission. Doing these out of order forces a restart.
Verify the number of sets, the seals, the binding, and that issue dates are still within the destination’s validity window.

|---|---|
| Notarial Services Attorney certification | For privately drafted instruments — powers of attorney, affidavits, consent letters — signed in the attorney’s presence. |
| Legalisation at the Department of Consular Affairs | Where a foreign authority needs confirmation of the Thai issuing office’s signature and seal, or of the translation. |

| Thailand’s Apostille status | Thailand acceded to the Apostille Convention on 30 June 2026 and it enters into force for Thailand on 28 February 2027. No Apostille is issued in Thailand before that date. |
