Signature Certification notarisation for Overseas — Thailand

Legal basis

Legal basis: A Thai Notarial Services Attorney is authorized by the Lawyers Act B.E. 2528 and Council regulations to perform acknowledgements, jurats/affidavits, certified copies, translation certifications and statements of fact. For overseas, consular legalization plus the destination embassy attestation is required after MFA. Wrong format equals rejection — every notarization here is pre-formatted for the destination authority.

Service workflow

Workflow for Signature Certification in Thailand: (1) submit scans plus destination purpose, (2) we audit format/language/affidavit suitability for overseas, (3) you sign in front of the Notary Public at our office or your preferred location, (4) ID is verified and the notarial seal applied, (5) originals, copies and certified translation are bundled with a cover letter, (6) MFA legalizes the notary signature, (7) the overseas embassy/consulate attests, (8) tracked delivery to you or directly to the destination authority.

Fees and pricing

Notary fee for Signature Certification ranges from ฿500 to ฿1,200 per set, varying with page count, complexity and language. Same-day rush adds 30-50%; on-site notary in Thailand adds travel fee. MFA and overseas embassy fees are billed as government pass-throughs — every quote includes the full breakdown.

Turnaround timeline

Typical timeline: notary appointment day 1 → MFA 1-3 business days → overseas embassy 2-7 business days, totaling ~3-10 business days subject to embassy queue. Same-day rush slots are available within 2 hours during office hours, with same-day MFA courier in Thailand.

Audience-specific pain points

Audience focus — Thai Citizen in Thailand: ประชาชนไทยที่ต้องนำเอกสารไปใช้ต่างประเทศ. Common rejection causes from overseas include wrong jurat/affidavit phrasing, uncertified translations, or out-of-order legalization. Our pre-check workflow eliminates these failure modes; if overseas rejects due to our error, we refund the notarial fee.

Frequently asked questions

Can a Thai Notary Public certify a Signature Certification for use in overseas?

Yes. A Lawyers-Council-licensed Notarial Services Attorney can notarize Signature Certification for overseas. After notarization, the document is sent for MFA legalization and, if needed, the overseas embassy or consulate. Hague members accept Apostille only.

What is the fee for notarizing this document?

Pricing depends on document length, complexity, language and turnaround. Refer to the price table on this page for tier-based pricing.

How long does notarization take?

Most notarizations are completed within 1 hour by appointment. Same-day rush is available. Combined Notary + MFA + embassy normally takes 3-7 business days.

What should I prepare before meeting the notary?

Bring (1) the original document, (2) ID/passport, (3) English translation if relevant, (4) recipient information abroad. We pre-check format compliance for overseas before each notarization.

Is remote notarization available?

For acknowledgements the notary must verify the original. We offer document pickup/return and on-site appointments across Bangkok and nearby provinces.

Are Thai-language documents accepted in overseas?

Most overseas authorities require English or their official language. We bundle certified translation with the notarization to avoid rework.
