FAQ
Do I need MOFA after notarization?
Depends on the destination. US, UK, Australia, and Canada accept notarized visas directly. Court use abroad usually requires MOFA authentication + embassy legalization. Apostille Convention countries (China, Hong Kong, France, Germany) need an Apostille — we handle the full chain.
Can I use this service outside Bangkok?
Yes — e-notarization via Zoom + EMS nationwide, or in person at our Khon Kaen, Udon Thani, Nong Khai, Phitsanulok, and Chiang Mai branches. Mobile service available in Bangkok metro.
Must the document be in English?
No — we notarize in Thai, English, Chinese, Japanese, German, French, and more. For overseas use we recommend pairing with a certified translation.
Can a Thai company notarize a PoA for overseas use?
Yes — directors sign before the NSA with company affidavit + signing authority. We chain with Apostille or MOFA + embassy legalization for China, US, UK, and beyond.
Can an Affidavit of Single Status be used for marriage abroad?
Yes — we issue an Affidavit of Marriageability in English, notarize it, pair with the Thai Kor.Ror.2, and authenticate at MOFA for foreign marriage registration.
Service Knowledge Base
Notarial Services Attorney (Notary Public) Knowledge Base
Common questions about signature and document certification by a Notarial Services Attorney in Thailand, and the follow-on MFA legalisation step. (64+ search topics covered)
Do I have to sign in person?
Yes for signature certification and sworn statements: you must appear with your original passport or Thai ID and sign in front of the attorney. For true copies you must bring the original document. If you are abroad, the practical route is to use a notary in your country of residence, or to schedule the appointment for your next trip to Thailand.
What makes a power of attorney fail abroad?
Authority drafted too broadly for the receiving bank or registry, names not matching the passport letter for letter, no expiry or scope for the transaction, and a missing legalisation layer. We draft the scope to the destination's requirement and check the spelling chain across passport, source document and translation before certifying.
Do you travel to clients or work outside Bangkok?
Yes. Our offices are in Bangkok (Lat Phrao), Khon Kaen and Udon Thani, and we attend hospitals, client offices and government premises by appointment. For provinces without an office we quote travel time and cost before confirming the booking.
Is notarisation alone enough for use abroad?
It depends on the receiving party. Universities, employers and many private counterparties accept an attorney certificate on its own. Foreign government bodies and courts usually require the next layer: legalisation by the Department of Consular Affairs of the Thai Ministry of Foreign Affairs, then legalisation by the destination country's embassy in Thailand. Always ask the receiving party in writing before you start.
Can you certify copies of my passport for an overseas bank account?
Yes, with the original passport presented. Many banks require the certificate to be within three months and to use specific wording such as “certified true copy of the original seen by me”. Send us the bank's form or instruction email before the appointment so the wording matches exactly.
What if the destination rejects the document?
If the rejection stems from something on our side — a typo, wording that does not match the instruction you gave us, or a missing certification layer — we redo the work at no service charge. New government fees follow the official tariff. Decisions that are within the discretion of the receiving authority remain outside our control.
Can Thailand issue an apostille yet?
Not yet. Thailand deposited its instrument of accession to the 1961 Apostille Convention on 2026-06-30, and per the HCCH depositary notice the Convention enters into force for Thailand on 28 February 2027. Until then Thai documents follow the two-step consular route. We plan document timing around whichever route applies on your filing date.
Affidavit or statutory declaration — which one do I need?
Both are written statements confirmed before an authorised person. Affidavits use sworn wording and appear mostly in litigation; statutory declarations use declared wording and appear mostly in administrative matters such as confirming status or a relationship. We follow the form the receiving authority prescribes and never draft wording beyond what the deponent actually knows.

Service Playbook
Notarial Services Attorney in Thailand — scope and documents
Thailand has no separate notary profession. Certification is performed by a Notarial Services Attorney licensed by the Lawyers Council, who certifies signatures and signing in their presence — not the truth of the content.
Documents to prepare
- • The document to be signed, left unsigned until the appointment
- • Original passport or Thai ID of every signatory
- • Recent company affidavit if signing for a legal entity
- • Company seal where the articles require it
- • Any wording template the destination requires
- • An interpreter or translation if a signatory cannot read the document language
Step-by-step process
- 1. Send the draft for review — We confirm which form of certification and wording the destination expects.
- 2. Attend the signing — Signatories appear in person with original identification.
- 3. Attorney issues the certificate — The certification carries the attorney's seal and registration number.
- 4. Continue the chain if needed — For foreign government use, the file proceeds to consular legalisation and beyond.
Pitfalls and rejection causes
- • Pre-signed documents cannot be certified as signed in the attorney's presence.
- • Signature certification is not a statement that the content is correct or enforceable.
- • Some jurisdictions demand specific certificate wording — check before booking.
- • Company affidavits older than the destination's limit are commonly rejected.
Tips from our team
- • Coordinate multi-party signings into a single appointment.
- • Prepare two spare sets in case several wet-ink copies are needed.
- • Tell us the document language ahead so an interpreter can be arranged.
Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.
Route Comparison
Notarial services attorney vs government certification
Many cases lose weeks simply because the wrong certifying party was chosen at the start.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Notarial services attorney | The receiving party is private — a university, bank or overseas counterparty | Attorney licensed by the Lawyers Council of Thailand | Usually same day | Some foreign government bodies require a further consular layer on top |
| Consular legalisation | The receiving party is a foreign government authority | Department of Consular Affairs, MFA Thailand | Variable, by queue and channel | Some private documents must have signatures notarised before consular submission is possible |
| Layered certification (attorney + consular + embassy) | Commercial contracts, powers of attorney, or documents used in foreign legal proceedings | Attorney with the Department of Consular Affairs and the destination embassy | Variable — allow several weeks | Skipping a layer usually means the whole bundle is rejected |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Advisory Service
We do not just process documents — we advise you through the whole case
Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
Route assessment
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Pre-submission review
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
Timeline planning
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
Rejection recovery
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.
Rather not learn by trial and error? Send your case details and document photos for a review — reach us on LINE, phone or email during business hours.
Practical Q&A
Practical questions · Near me / DIY / Required documents
Where can I find a notary public near me in Thailand?
Thailand has no US/UK-style notary public. The authorised signatory is a “Notarial Services Attorney” licensed by the Lawyers Council of Thailand under Royal Patronage, so the work must be done at a firm with such a licensed lawyer. Our main offices are Lat Phrao 95 (Bangkok), Khon Kaen and Udon Thani, with meeting points near BTS/MRT stations and city malls. Ask our team by phone, LINE or email for the most convenient point.
Can I notarise a document myself without a firm?
No. Only a lawyer holding the Lawyers Council notarial-services licence may certify. What you can prepare yourself is the paperwork: the correct original or true copy, and your ID. Signature certification requires you to sign in front of the attorney, so do not sign the document in advance.
Which documents do I need to bring for notarisation?
At minimum: (1) your original passport or Thai ID card; (2) the exact document version you will submit; (3) for company signatories, a company affidavit dated within the period your recipient accepts, plus the seal if used; (4) the destination country and receiving authority, because the wording of the certificate and any onward steps (for example whether MFA legalisation is needed afterwards) depend on the destination.
Practical advice & cautions
Notarial services in Thailand: advice and cautions
Before you start
Add a translation for foreign-language documents
If the document will be used with Thai authorities or filed at an embassy, prepare a translation alongside it to avoid follow-up requests.
Bring original documents, not photos or scans
A certified true copy must be compared against the original in person. If the original is abroad or lost, obtain a certified reissue from the issuing authority first.
Tell us the destination authority first
What happens after notarisation differs by country and receiving authority. Some accept the attorney's certification alone; others require further authentication by the Department of Consular Affairs and the destination embassy. Naming the country and authority up front lets us sequence the work correctly.
Confirm the document list before you travel to us
The type of certification, number of sets and the follow-on steps change what you must bring. Contact our team by phone, LINE or email to confirm first.
Common reasons documents get rejected
Expecting an apostille issued in Thailand
Thailand is not a party to the Apostille Convention. Documents for overseas use follow authentication by the Department of Consular Affairs and the destination embassy instead.
Expired ID or mismatched name spelling
Names must match your passport. If you changed your name or the spelling differs, bring the supporting change-of-name evidence.
Assuming Thailand has a common-law notary public
It does not. Certification is performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand. If your recipient specifically requires a Notary Public, confirm in advance that they accept this form of certification.
Believing certification validates the content
Certification covers facts observed in person — that the person signed, or that a copy matches the original. It does not certify that the statements are true or legally effective abroad.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
