Notarial Services Attorney vs MFA legalization — which do you need?
In Thailand, notarial certification is performed by lawyers licensed by the Lawyers Council of Thailand, while MFA legalization certifies the seal and signature of Thai officials so a document can be used abroad. Many files need both, in sequence.
Bottom line: Documents you sign yourself (POA, affidavits, certified copies) start with a notarial attorney. Thai public records (household registration, birth certificate, transcripts) start with translation and MFA legalization.
