Frequently asked questions
How to use these guides and where the official rules live
Who writes these guides and how current are they?
They are written by the ILC document team from casework on notarial services, certified translation, and consular legalization in Thailand. Each article shows its publication or update date. Where a rule comes from a government authority, we link the official source so you can verify the current wording yourself.
Can I rely on an article instead of the authority's own instructions?
No. Treat the guides as orientation for planning. Requirements change, and the binding version is always the current notice published by the Thai authority, the destination embassy, or the immigration department that will receive your file.
Do the guides cover documents issued outside Thailand?
Yes. Several articles explain the inbound route: certification in the issuing country first, then Thai translation, then certification of that translation by the Department of Consular Affairs before submission to a Thai office such as a district office, the Land Department, or Immigration.
Why do the articles avoid stating fixed fees and turnaround days?
Government fees and queue times are set by each authority and change without notice, so quoting a fixed number would mislead readers. We describe the sequence of steps and the factors that lengthen it, and we give a current quotation for our own work directly on request.
Are the English guides translations of the Thai articles?
They are written for a different reader rather than copied. The English set assumes a foreign applicant dealing with Thai offices, so it explains which office issues each document and what a foreign authority will expect to see on the certified translation.
How do I ask about a case the guides do not cover?
Send a scan of the document and name the authority that will receive it. That pair determines the certification chain. You can reach the team by phone, email, or LINE, and we will confirm the steps that apply before any work begins.
