Does a Thai ID card need notarisation or MFA legalisation before a tourist visa?

In brief, before the detail — Thai civil-registration documents for a visa file normally follow this chain: (1) obtain an original or government-certified copy issued recently enough for the destination authority, (2) translate through a translator the destination accepts — a Department of Consular Affairs recognised translator, or a NAATI certified translator for Australia and New Zealand, (3) certification by a Thai Notarial Services Attorney where required, (4) MFA legalisation, and (5) destination embassy attestation where that is still requested. We handle the document side of a visa file only — translation, Notarial Services Attorney certification, MFA legalisation and embassy attestation. We do not give immigration legal advice and never promise an approval outcome. Tell us the destination country and visa subclass and we bundle translation → notarisation → MFA legalisation → embassy attestation in one run.
