Before commissioning this work

A power of attorney may contain conditions set by a bank, land office or foreign recipient. Obtain that institution’s form and signing instructions before asking for a seal; a different form may not serve the intended purpose.

Copy certification does not establish that the document’s contents are legally correct, and witnessing a signature is not a review of every contract term. If legal advice or drafting is needed, request it as a separate scope.

Corporate signing requires more than a passport. Ask what evidence establishes the signatory’s authority and whether a board resolution, company record or representative document is needed for the particular transaction.

Thailand deposited its instrument of accession to the 1961 Apostille Convention on 2026-06-30, and the Convention enters into force for Thailand on 28 February 2027. Before that date, a Thai apostille cannot replace required authentication. Confirm whether the recipient requires translation, consular legalisation or another certificate; not every document needs notarisation or embassy authentication.

Official references

Confirm the recipient’s current instructions before submitting originals. References identify authorities, not endorsement of this provider.

Why clients choose us for this

  • Distinguish witnessing a signature from certifying a copy
  • Check the attorney’s relevant registration before commissioning
  • Review signatory identity and representative authority
  • Confirm whether the receiving office needs any later authentication

Documents commonly handled

A non-exhaustive list — bring anything you're unsure about.

  • Unsigned document or recipient-provided form
  • Original passport or identity document
  • Original record for any requested copy certification
  • Evidence of authority to sign for a company, where applicable

Step-by-step process

  1. 1

    1. Confirm the requested act

    Send the form and the recipient’s instructions. Clarify whether it needs a witnessed signature, affidavit or certified copy.

  2. 2

    2. Arrange identity and authority checks

    Ask staff which originals and representative documents the attorney needs and confirm appointment availability.

  3. 3

    3. Complete the relevant notarial act

    For a witnessed signature, do not sign beforehand unless the attorney gives instructions. The attorney determines the appropriate identity, presence and signing checks.

  4. 4

    4. Check the next submission step

    Keep a copy and confirm the recipient’s delivery and any authentication requirements. Do not assume every notarised document needs an embassy chain.

Frequently asked questions

Q. Should I sign before my appointment?

For signature witnessing, normally leave the form unsigned until the attorney gives instructions. Copy certification and other acts have different requirements; send the requested wording before booking.

Q. Does notarisation guarantee overseas acceptance?

No. The receiving office decides which act and certifying professional it accepts. Some require further signature authentication and others do not; obtain written instructions for your document.

Q. How do I verify the professional?

Ask for the attorney’s name and relevant Notarial Services Attorney registration details, then check with the Lawyers Council of Thailand. No unverified headcount or credential number is a substitute for checking the individual assigned.

Q. Is drafting included in the fee?

Not necessarily. Document drafting, legal advice, witnessing and later authentication are separate scopes. Request an itemised written quote before agreeing the work.

What to prepare before filing Notary

  • Original document required for Notary (or a freshly issued certified copy within its validity window)
  • Copy of national ID or passport, signed and dated as a true copy
  • Power of attorney (if a representative will handle it) with a 30 THB revenue stamp
  • Destination details: country, receiving authority, purpose, and required deadline

Notary: the working sequence

  • 1. Send scanned copies of the Notary source documents via LINE/email for a free initial review.
  • 2. We confirm eligibility and issue a written quote with a committed turnaround.
  • 3. You deliver originals to our office (or book a Bangkok pickup) and pay a 50% deposit.

  • 5. Final documents are scanned and emailed for your review before physical dispatch.
  • 6. We ship by EMS domestically and DHL/FedEx internationally, with tracking numbers.

Why Notary filings get rejected

  • Dates that disagree across documents — this must be fixed at the issuing agency; it cannot be corrected at the translation stage.
  • Skipping MFA legalization before the embassy step — this costs multiple trips and several weeks.
  • Submitting an uncertified photocopy instead of the original — the receiving office will not review it and you rejoin the queue.
  • Using a translator without an official seal — the MFA and embassies will not accept it, and the chain restarts.

Common Pitfalls (From Field Experience)

  • Signing before arriving at the notary — the signatory must physically sign in the notary's presence.
  • Using an expired passport or ID on the day of notarization voids the certification.
  • Self-translating documents rather than using a Ministry of Justice–listed translator often causes rejection abroad.
  • Conflating Notary with Apostille — Thailand is not (yet) a Hague Apostille state, so documents still require MFA + destination-embassy legalization.

Scope of work: Notary Public / Notarial Services Attorney

Signature witnessing, certified true copies, affidavits and translation certification by a Thai Notarial Services Attorney, for documents used by overseas authorities or counterparties.

This service fits you when

  • You must sign a contract, power of attorney or overseas form that says it has to be notarised
  • You need certified copies of a passport, ID card or degree for a job, study or overseas bank application
  • You need an affidavit or statutory declaration in the wording the receiving side requires
  • You want a lawyer's certification attached to a translation before it goes to the MFA or an embassy

When another route is the right one

  • If the destination asks for an Apostille or consular legalisation, notarisation alone is not enough — we map the full chain
  • Thai civil records such as birth certificates usually need translation plus MFA certification, not notarisation
  • If the destination is Australia and wants a NAATI translator, the NAATI route applies instead

What the service includes

  • Checking the destination's requirement first and choosing the correct certificate type
  • Formatting the document and drafting the jurat / acknowledgement wording
  • Booking the in-person signing with the attorney and verifying photo ID
  • Seal, signature and register number issued under Lawyers Council rules
  • High-resolution scans sent first, originals couriered to your address

What is not included

  • Government and courier fees charged by the receiving authority (billed at cost, always quoted before we start)
  • Any guarantee of approval by a government office or embassy — that decision stays with the officer in charge
  • Sourcing original documents that only you can request in person

Notary Public process and required documents

Notarial work is usually completed within one business day; the signer must appear in person with original documents before the notarial services attorney.

Step-by-step process

  1. 1Pre-check your fileSend a scan and tell us the destination country/authority so we can confirm the correct certificate type (signature, true copy, affidavit or translation certification).
  2. 2Format and draft the certificateWe lay out the document, add the correct jurat or acknowledgement wording and mark where you must sign in front of the attorney.
  3. 3Sign in personThe signer presents an original ID or passport and signs before the attorney at our office or at an agreed location.
  4. 4Seal and registerThe attorney signs, seals and records the certificate number so the notarisation can be verified later.
  5. 5Continue the chain if neededIf the destination requires it, we carry the file through MFA legalization and embassy attestation, or prepare the apostille set, so you never queue yourself.

Documents you need to prepare

  • The original document (scan in advance, original on signing day)
  • Original ID card or passport of every signer
  • For companies: company affidavit issued within 6 months plus a power of attorney
  • The destination country and authority the document is filed with

Common pitfalls to avoid

  • Do not sign in advance — signature certification requires signing before the attorney.
  • A Thai notarial attorney certifies signatures and copies, not the truth of the content.
  • Some countries require MFA and embassy steps afterwards; check the chain before you start.

Compare the options before you decide

Apostille route vs embassy legalisation route

The destination country decides whether a file ends at an Apostille or still needs the embassy. Confirm the country's convention status first: the two routes use a different order and different paperwork.

AspectApostille routeEmbassy legalisation route
When it appliesDestination is a party to the Apostille ConventionDestination does not accept an Apostille
Final authorityDepartment of Consular Affairs, Ministry of Foreign AffairsThe destination country's embassy or consulate in Thailand
Typical number of stepsFewer — the chain ends at the central authorityMore — central authority first, then the embassy
Approximate timeframeShorter, still subject to the authority's queueLonger, because the embassy appointment queue is added
Common rejection causeTranslation does not match the original, or the copy was not issued by the authorityThe embassy's own form or language requirement was not followed

Verify the current convention status and embassy conditions before filing.

Thailand's notarial attorney vs a foreign Notary Public

Thailand has no Notary Public office in the international sense. Equivalent work is performed by a Notarial Services Attorney licensed by the Lawyers Council of Thailand.

AspectThailand: notarial attorneyAbroad: Notary Public
Who is authorisedAn attorney licensed for notarial services by the Lawyers CouncilA notary appointed by the state or a court
ScopeSignature certification, true copies, affidavits and translations where the law allowsVaries by jurisdiction
Usual next stepFile with the Department of Consular Affairs, then Apostille or embassyUsually the country's own central authority
In-person requiredYes — you sign in front of the certifying attorneyGenerally yes

Where the receiving body uses its own terminology, follow that wording rather than claiming an equivalent title.

Filing it yourself vs letting NYC run the chain

Every step can be done alone. This table compares the real workload of each option so the decision rests on time and rejection risk rather than marketing claims.

AspectDo it yourselfNYC handles it
Checking destination rulesRead each authority's notice yourself and confirm by phoneChecked before you start, with the order the receiving authority accepts
TravelSeveral agencies with queues that rarely line up in one dayDocuments move by courier or online except where the law requires you in person
Rejection riskOne mismatch — a name spelled differently from the passport — restarts the chainNames, dates and stamps are cross-checked before every filing
Status trackingYou follow up with each authorityStatus updates at each stage, and we handle the fix if a file is returned
Advisory roleNo one to compare options when your case falls outside the manualYou get advice on the options before work starts, not just execution

Government fees and timeframes change; ask for an assessment of your own case before you start.

5 mistakes that get notarised documents rejected abroad

Most problem files are not caused by the document itself, but by the order of steps and small identity details before signing.

  1. 1. Signing the document before meeting the attorney

    Why it matters: Signature notarisation must happen in front of the certifying attorney.

    How to avoid it: Bring the document unsigned and sign it at the appointment.

  2. 2. Expired ID or a name spelled differently across documents

    Why it matters: Identity must be verified from valid ID and the spelling must match exactly.

    How to avoid it: Check expiry dates and English name spelling across the whole set first.

  3. 3. Assuming a Thai notarial certification equals a foreign Notary Public

    Why it matters: Thailand uses Notarial Services Attorneys; some receivers ask for further legalisation.

    How to avoid it: Confirm with the receiving authority whether consular legalisation is also required.

  4. 4. Certifying a copy without presenting the original

    Why it matters: True-copy certification requires the physical original for comparison.

    How to avoid it: Always bring the original, even if scans were reviewed in advance.

  5. 5. Missing company documents when a director signs

    Why it matters: Signing authority must be evidenced or the certification can be challenged.

    How to avoid it: Bring a recent company affidavit plus the signatory's ID or passport.

What the common mistakes actually cost

Almost every failure in notarial signature certification by a licensed attorney happens during preparation, not at the counter, and the real cost is the TIME needed to repeat the chain. Below is what each mistake comes from, how long it typically adds, and how to avoid it.

MistakeWhy it happensTime costHow to prevent it
Filing an incomplete set — missing an ID copy or a power of attorneyCompleteness is checked at the counter; an incomplete file is not accepted at all.Typically adds 1–5 working days per return trip.Work from a written checklist and re-check it before leaving, including every copy that needs a signature.
Planning without allowing for public and embassy holidaysEmbassies close on both Thai and home-country holidays, so the real calendar is shorter than it looks.Typically adds 3–9 working days around a long holiday period.Check the holiday calendar of every body involved before fixing a travel or filing date.
Running the chain in the wrong order — embassy before the consular departmentEach body only certifies the signature of the body immediately before it in the chain.Typically adds 5–12 working days and forces a re-filing from the skipped stage.Confirm the route with the receiving authority before starting, or have us map the chain up front.
Self-translating, or using a translator the destination does not recogniseSome countries accept only registered translators, others only translations certified by a Thai government body.Typically adds 4–10 working days for a fresh translation and a restarted chain.Ask the destination exactly which form of translation it accepts, then match the translator to that form from the start.
Using an old copy instead of a freshly issued oneMany destinations accept documents issued within the last 3–6 months only, and some require a clean, legibly sealed reissue.Typically adds 5–15 working days for the trip back to the district registrar.Check the destination's freshness rule first, then request several certified copies in a single visit.

Deep timeline: what can run in parallel

The windows below are approximate and depend on each authority's queue. Stages marked as parallel can start alongside the previous stage — that is where the total calendar time is actually reduced.

  1. 1. Document review and certificate wordingsame day

    We confirm whether you need a signature certification, a true-copy certification, or a statement of fact — each uses different wording.

  2. 2. Signing appointment in person1–2 working days

    The signatory must appear with an original ID or passport at the moment of signing.

  3. 3. Certificate issued and sealedsame day

    The certificate is issued with a register number and logged under Lawyers Council rules.

  4. 4. Onward legalisation, if the destination requires it3–10 working dayscan run in parallel

    For overseas use the file may still pass the consular department and then the embassy, in that order.

Note: all windows are general estimates, not guarantees. Actual timing depends on how complete your file is and on the queues at the authorities involved.

We work as advisers, not only as a document-running agency

Our team has worked on documents, translation and legalisation for more than 15 years, combining notarial attorneys licensed by the Lawyers Council of Thailand with translators the receiving authorities accept. Every case starts with advice on the correct route and only then moves to execution — we do not simply run whatever is handed to us.

Before we start — mapping the document route

We confirm whether your file ends at an Apostille or still needs the embassy, whether a freshly issued copy is required, and which form of translation the receiving authority accepts. This is where most time is saved, because it is where most people choose wrongly and restart.

While preparing — consistency checks

We match the spelling of your name against the passport, check the issue date against the validity window the destination applies, verify stamps and signatures, and confirm the translation matches the original line by line.

While filing — coordination with the authorities

We file in the order each authority expects, follow the queue, and report status as it moves. If an authority asks for more paperwork, you hear about it immediately, together with the options for fixing it.

After delivery — practical guidance

We explain which bodies this set can be filed with, how to store the originals, and how many certified sets to request up front if you expect to use them again, so you do not repeat the whole chain later.

Cases where advice up front changes the outcome

  • The applicant is upcountry or abroad, so the power of attorney and courier plan must be arranged carefully.
  • Documents are needed for several countries at once, each with a different order of certification.
  • Documents have a limited validity window and every item must still be valid on the day of filing.
  • The name on an older document does not match the current passport because of a name change or a different transliteration.

If you are unsure which route your case takes, send photos of the documents and name the destination country or authority. We map the sequence and the paperwork first; you then decide whether to run it yourself or hand it over.
