Frequently asked questions

What is a Notary Public in Thailand?

Thailand uses Notarial Services Attorneys licensed by the Lawyers Council of Thailand. They perform core functions including signature certification, certified true copy, affidavits, powers of attorney, contracts, translation certification and fact certification.

How is the fee calculated?

Fees depend on document type, language, number of signatories, and any onward MFA or embassy steps. Ask our team for a quote via LINE @THAIL or 064-2894888.

Do I need to appear in person?

Signature certification normally requires the signer to appear with original ID so identity can be verified. Some copy certifications can be assessed from documents sent in advance; we confirm what applies to your case.

Will my embassy accept the notarization?

Notarization by a registered Notarial Services Attorney is a common first step before MFA or embassy legalization. Each receiving authority sets its own rules, so we check its current checklist before submission.

Where are your offices?

We have two offices: Bangkok (61 Soi Lat Phrao 95, Wang Thonglang) and our Khon Kaen head office (680/45 Na Mueang Road). Other provinces are served through partner attorneys; ask us which option fits your location.

How long does it take?

Timing is assessed based on your documents, the number of sets and any onward legalization. We give you an estimate once we have reviewed your file.

Can you help with translation into Thai or English?

Yes. We can arrange translation and certification of the translation for common language pairs. Tell us the languages involved and we will confirm availability before starting.

Can you handle the full chain (notary + MFA + embassy)?

We can coordinate translation, notarization and the onward MFA and embassy steps as one managed workflow. Each authority's own requirements and processing still apply.

What should I bring for a signature certification?

Bring the unsigned document, your original passport or Thai ID card, and any instructions from the receiving authority. Do not sign in advance — the attorney must witness the signature.

Can a company director sign on behalf of a Thai company?

Yes, if the director has signing authority. Bring a recent company affidavit (DBD certificate) showing authorised directors and the signing conditions, plus the company seal if the articles require it.

Can I get an Apostille for a Thai-issued document?

Do not assume a Thai-issued document can receive an Apostille in Thailand. Check the current status and the receiving authority's required legalization path before preparing the document.

Can you notarize a document written in a foreign language?

Often yes, but the attorney must understand what is being certified. A translation may be needed so the signer and attorney both know the content. We review the document first.

What documents cannot be notarized?

We decline documents that appear falsified, incomplete, signed under pressure, or where identity cannot be verified. A notary certifies acts such as signatures or copies; it does not guarantee that the content is legally valid.

Can I get a certified copy of my degree or passport?

Yes. Bring the original; the attorney compares it with the copy and certifies it as a true copy. Some universities or authorities require their own certification instead, so check the receiving institution's rules.

Related services and next steps

Notarization is usually one step in a longer document chain. These pages cover what typically comes before and after it.

Who acts as a notary in Thailand

Thailand has no civil-law style Notary Public office. The work is done by a Notarial Services Attorney — a Thai lawyer who has completed training and is registered with the Lawyers Council of Thailand. The attorney certifies facts witnessed in person: that the signer is the person named on the ID and signed in front of them, or that a copy matches the original produced. A notarial certificate does not confirm that the contents are true or legally valid in the destination country.

Common requests

  • Signature certification on powers of attorney, contracts and child travel consent letters
  • Certified true copies of passports, degrees and company affidavits
  • Affidavits and statutory declarations, e.g. single status or name variations
  • Corporate documents for overseas bank accounts, tenders or foreign authorities

What usually comes after notarisation

Many foreign authorities require a chain: Thai government documents go to the Legalization Division of the Department of Consular Affairs, then to the destination country's embassy. Private documents usually need the notarial certificate first, then the same chain. Thailand acceded to the Apostille Convention on 30 June 2026; it enters into force on 28 February 2027, and until then the legalisation chain still applies. We confirm the destination country and receiving authority before starting.

What to bring on signing day

  • Original passport or Thai ID for every signer
  • The unsigned document — it must be signed in front of the attorney
  • Originals for any certified copy
  • For companies: a recent company affidavit and proof of director authority
  • Any form or instruction from the receiving authority

Why documents get rejected

The usual causes are documents signed in advance, names that do not match the passport, outdated form versions, or a skipped legalisation step. We check these before booking. Appointments are available at our Bangkok and Khon Kaen offices or through our partner network in every Bangkok district and every province. Service fees: ask our staff for a quotation. Consular and embassy fees follow each authority's published schedule.

Frequently asked questions

Can a Thai notary certify a translation?

The attorney can certify that the translator signed the translation declaration in person, not that the translation is accurate. If the authority requires a specific credential such as NAATI, use a translator with that credential.

What if the signer is upcountry or abroad?

Within Thailand we can arrange a partner appointment near the signer. Abroad, signing usually has to happen before a local notary or Thai embassy — check with the receiving authority first.

Can I get an Apostille instead of consular legalisation now?

Not yet. The Convention takes effect for Thailand on 28 February 2027; until then consular and embassy legalisation applies.
