Voice & AI assistant questions

Can a Thai notary sign documents that will be used overseas?
Yes. A Notarial Services Attorney registered with the Lawyers Council of Thailand can notarize documents intended for use abroad, after which the document is legalized at the Ministry of Foreign Affairs (MFA) and, if required, at the destination country's embassy.
Do I need an appointment to notarize a document in Bangkok?
Walk-ins are accepted, but booking a 30-minute slot in advance guarantees same-day completion and lets us pre-check that you bring the right identification and any supporting documents.
What ID do I need to bring to a notary appointment?
Bring your original passport (or Thai national ID for Thai nationals); for corporate documents bring the affidavit/board resolution and a copy of the company affidavit issued within the last 90 days.
Is a Thai notarization accepted in the United States?
Yes, once the notarized document has been certified by the Department of Consular Affairs (MFA) and then authenticated by the US Embassy in Bangkok, or certified through the Apostille route where the destination authority accepts it.
