Frequently Asked Questions

How long does Administering Oaths take?
Usually completed within 1 business day. Express service within 2 hours is available in Bangkok.
Is Administering Oaths accepted overseas?
Yes, worldwide. After legalisation by Thailand's MFA Consular Department and the destination embassy. Hague Apostille is accepted in 130 Contracting Parties (Thailand joined in 2025).
What is the starting fee?
From Request a quote/set up to Request a quote depending on volume and language pairs.
Can I pre-sign the document?
No. Thai law and professional ethics require the signature to be witnessed in the Notary's presence.
Do you offer mobile / on-site service?
Yes. Our attorneys travel across all 50 Bangkok districts and 5 surrounding provinces. Travel fees apply.

Legal Framework & Source of Authority

The service operates under the Lawyers Council of Thailand's 2008 regulation (and subsequent amendments) on the registration of notarial services attorneys. Only attorneys who pass the Council's training and exam are licensed; clients can verify license status through the Council's public registry.

Thailand uses a Notarial Services Attorney system instead of the western Notary Public model. A licensed attorney may certify signatures, identity, status, and copies for both domestic and international use, recognised by Thai courts, the Ministry of Foreign Affairs, and foreign embassies.

Authority is rooted in the Civil and Commercial Code, the Lawyers Act, and the Lawyers Council's regulations — covering oath administration, true-copy certification, and negotiable-instruments protests under the Bills of Exchange Act.

International Use (Apostille / Legalisation)

From 28 February 2027 (entry into force for Thailand), Thailand has been a contracting state of the Hague Apostille Convention (HCCH 1961). Documents issued in Thailand may now be used directly in 130 Contracting Parties with a single Apostille — no destination-embassy step required.

For non-Apostille states, the full legalisation chain applies: attorney → Thai MFA Consular Department (Chaeng Watthana / MRT Khlong Toei) → destination embassy in Bangkok.

Apostille only authenticates the official's signature/seal — not the substantive content. The document still has to comply with the destination country's law.

Common Real-World Scenarios — Administering Oaths

Foreign nationals who need education, financial, or property documents accepted by government offices, banks, or universities back home.

Thai companies signing contracts with counterparties in China, Japan, Korea, Germany, or the United States and filing documents with foreign courts or regulators.

Cross-border families registering marriages, adoptions, or estate matters overseas.

Fees, Turnaround & Required Documents

Fees depend on page count and complexity, and include pre-review, the notarial act, stamp duty, and duplicate originals. Most jobs finish the same day.

Adding MFA legalisation extends the timeline by ~2-3 business days and adds an official fee of THB 400-800 per set.

Risks & What to Avoid

Avoid providers who claim to be 'Notary Public' without a Lawyers Council license — documents certified by an unauthorised person are rejected by the MFA and embassies on sight.

Do not pre-sign the document. Professional ethics require the signature to occur in the attorney's presence.

How to Choose the Right Notarial Services Attorney

Verify the attorney's license number against the Lawyers Council registry, check experience with the target jurisdiction (CN/JP/KR/EU/US), and confirm availability for on-site service across Bangkok and upcountry provinces.

Additional frequently asked questions

Do I have to sign in person before the attorney?
For signature attestation, yes — the signer must appear with an original passport or Thai ID card and sign in the attorney's presence. Certified true copies and certain fact attestations can be handled from originals without a fresh signature, depending on what the receiving authority requires.
Can the attestation be used abroad immediately?
It depends on the destination. Many countries additionally require legalisation by the Department of Consular Affairs, Ministry of Foreign Affairs, and sometimes by their own embassy in Bangkok. Confirm the receiving party's chain before starting so the work is not repeated.
Do Thai-language documents need translation first?
If the recipient is a foreign authority, an English translation (or the official language of that country) is normally required, and the translation itself may need certification. The correct order is translate, certify the translation, then legalise.
What is needed to certify corporate documents?
Typically a company affidavit issued by the Department of Business Development within the recency window the recipient allows, ID or passport of the authorised director, the company seal if one is used, and the document to be attested. Scope and requirements are confirmed case by case by phone, LINE or email.
How long does an attested document stay valid?
The attestation itself has no expiry, but recipients such as embassies, banks and universities commonly require documents issued within the last 3–6 months. Always check the recipient's recency rule first.
What if the destination authority rejects the document?
Ask for the rejection reason in writing. Most rejections come from wording of the attestation clause, the order of the legalisation chain, or a translation that does not match the required format — each of which can be corrected without redoing the whole set.

How this connects to the next step

When the source document is in Thai, prepare the certified translation into the destination language before the notarial appointment, because the notary certifies signatures on the bundle that already contains the translation. The full sequence is set out in our step-by-step workflow.

In depth: the real requirements and why documents get rejected — Notary Public

Written from the competent authority's published rules, not marketing copy.

Notarial work in Thailand is performed by lawyers registered with the Lawyers Council of Thailand who hold the notarial services endorsement. Verifying that the certifier's registration is current is a step the document owner can and should perform before discussing wording or scheduling.

Conditions you actually have to clear

  • For a true-copy certification, the original must be produced on the day; comparison against an image file is not accepted by most authorities.
  • If the signatory cannot read the language of the instrument, an interpreter must be present and that fact recorded in the certificate.
  • The signatory must appear in person with an unexpired passport or national ID card; a scan sent in advance cannot substitute for appearance.

Common causes of rejection

  • Signing in advance and asking for a backdated certificate — the attestation of signing in the certifier's presence would not match the facts, and the receiving body normally rejects the whole file.
  • Using signature-witnessing wording when the destination asked for a certified true copy; the two forms are not interchangeable.

The safest approach is to obtain the receiving authority's requirements in writing first, then match the certificate wording and the chain order to them. If anything is unclear, send us the destination country and the intended use by phone, LINE, or email before any signing appointment.

Practitioner guidance — Certification by a Notarial Services Attorney

Competent authority: Lawyers Council of Thailand

Practitioner guidance

  • 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.
  • For companies, bring a recent company affidavit and evidence of directors' signing authority.

Pitfalls — why documents get rejected

  • A company affidavit older than the destination accepts.
  • 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.

In-depth questions and answers — Certification by a Notarial Services Attorney

Answers follow the competent authority's published requirements, not marketing copy.

What if our Certification by a Notarial Services Attorney case has unusual conditions?

For edge cases — mismatched names across documents, foreign-issued records, or a tight deadline — have the set reviewed first, then reconfirm the conditions with Lawyers Council of Thailand. Ask our staff by phone, LINE or email for scope and timing (we do not publish fees on the page because they depend on the document type and destination). This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How long does Certification by a Notarial Services Attorney take?

Turnaround is not fixed: it depends on the queue and rules of Lawyers Council of Thailand, the document type, and the receiving office abroad. For that reason we do not publish a fixed figure. Plan a buffer before your real deadline and ask our staff by phone, LINE or email for the current queue before booking travel. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Does the result of Certification by a Notarial Services Attorney expire?

Validity is set by the receiving office, not by the service provider. Many offices accept only recently issued documents, so confirm the destination's window first and only then start the process with Lawyers Council of Thailand, to avoid the document expiring while it waits in the queue. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Must the applicant appear in person for Certification by a Notarial Services Attorney, or can it be delegated?

Some steps require the document owner to sign or appear; others accept a power of attorney. It depends on the rules of Lawyers Council of Thailand and on the document type, so confirm before booking an appointment rather than travelling and being turned away. Our staff can clarify by phone, LINE or email. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Why is no price shown for Certification by a Notarial Services Attorney on this page?

Scope varies widely per case — page count, languages, number of certification rounds, and the official fees charged by Lawyers Council of Thailand under its published schedule.

This is general guidance; requirements and processing times change — verify with the competent authority before filing.
