What is the difference between notarisation and legalisation?

Notarisation is performed by a Notarial Services Attorney and certifies a signature, a declaration or a true copy. Legalisation is performed by a government body — the Department of Consular Affairs and then an embassy — and certifies that the previous official's signature and seal are genuine. Many files need both, in that order.

Can a foreign document be legalised in Thailand?

Only after it has been authenticated in the country that issued it. A foreign birth certificate, for example, is apostilled or legalised at origin, legalised by the Thai embassy there where required, translated into Thai and then submitted to the Department of Consular Affairs. Thai officials cannot certify a foreign registrar's signature directly.

How long does consular legalisation take?

Department of Consular Affairs processing is typically 2–4 business days for standard service once the file is complete, and embassy processing depends entirely on that mission's own schedule, which can range from same-week to several weeks. Timeframes are ranges because government queues cannot be guaranteed.
