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 Thai documents need to be translated?

Usually yes, into English or the official language of the destination. The widely accepted approach is for the translator to sign a declaration in front of the attorney so the original and the translation are certified together. For Australian filings that specify NAATI, use a NAATI translation instead, because some authorities accept only that format.

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.

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.

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.

What does a company need to bring?

A company affidavit or certificate of incorporation issued within the destination's accepted window, ID or passport of the authorised director, the company seal if the articles require it, and a board resolution when the transaction requires one. Directors must sign in front of the attorney; pre-signed documents can only be handled as certified copies.

How do I verify that the attorney is properly registered?

Ask to see the lawyer's licence and the Lawyers Council registration for notarial services. Every certificate should show the attorney's full name, licence number, signature and seal. If in doubt you can ask the Lawyers Council of Thailand to confirm the registration.

Does a certification expire?

There is no statutory expiry, but receiving parties commonly require certification within three or six months, especially banks, immigration authorities and company registries. Start the process once your filing date is known so the certificate is still inside that window when you submit.

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.

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. 1. Send the draft for review — We confirm which form of certification and wording the destination expects.
  2. 2. Attend the signing — Signatories appear in person with original identification.
  3. 3. Attorney issues the certificate — The certification carries the attorney's seal and registration number.
  4. 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.

RouteWhen to useCertifying authorityApprox. durationRejection risk
Notarial services attorneyThe receiving party is private — a university, bank or overseas counterpartyAttorney licensed by the Lawyers Council of ThailandUsually same daySome foreign government bodies require a further consular layer on top
Consular legalisationThe receiving party is a foreign government authorityDepartment of Consular Affairs, MFA ThailandVariable, by queue and channelSome 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 proceedingsAttorney with the Department of Consular Affairs and the destination embassyVariable — allow several weeksSkipping 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

  • 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.

  • 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.

  • The signer must sign in front of the attorney

    Signature certification confirms the signature was made in person, so bring a valid original ID card or passport and do not sign the document in advance.

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.

  • Stopping before the follow-on steps

    Many files are rejected because they stop at the attorney's certification when the recipient also required consular and embassy authentication. Plan the full chain from the beginning.

  • 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.

  • 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.

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.
