Practitioner guidance — Certification by a Notarial Services Attorney

Competent authority: Lawyers Council of Thailand

Practitioner guidance

  • Thailand has no standalone Notary Public office; certification is performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand.
  • The signatory must sign in front of the attorney and present an original passport or Thai ID card.
  • Bring the complete original document, including blank and stamped pages.
  • Tell the attorney the destination country and authority in advance, since the certification wording differs by use.
  • If the document is for overseas use, plan the next steps (MFA legalisation, Apostille or embassy) from the start.

Pitfalls — why documents get rejected

  • Foreign-language forms with no translation for the signatory to understand.
  • Describing the role as international 'Notary Public' when the Thai system uses a different designation.
  • Signing in advance — the attorney cannot certify a signature made out of their presence.
  • Presenting a passport copy instead of the original on the day.
  • Documents containing alterations or strike-throughs without initials.
