Case example — Notary Public: bilingual commercial contract (Mukdahan → the United Kingdom)

Following the order the authorities expect, this type of file runs through 5 main steps, starting with "Confirm what the FCDO Legalisation Office accepts: the document format required and how many layers of certification apply." and ending with "Run a final checklist before handover and flag the follow-up risks if the receiving authority asks for further documents.". The receiving body is the FCDO Legalisation Office, which checks both the content and the order of certification. Skipping a step usually means the file is returned and the process restarts.

Prepare Name or surname change certificate (if any) · The signatory's original passport or Thai ID card · Most recent company affidavit (for corporate applicants) · Copy of the house registration before the first step. Names in English must match the passport spelling on every document, and a freshly issued copy is safer when the receiving authority sets a validity window.

In practice, the working estimate is roughly 7–10 working days, depending on government queues and public holidays. Allow extra time when several layers of certification are required or when originals travel between provinces.

The destination authority accepts documents issued no more than 3–6 months earlier — the fix is: Request a freshly issued copy before starting certification rather than reusing an older one. Checking this single point before filing removes the most common cause of a second round.
