Key takeaways
Only attorneys registered with the Lawyers Council of Thailand under the Lawyers Act B.E. 2528 may certify
You must sign in front of the attorney and present an original passport or Thai ID card
Documents used abroad usually also require MFA Department of Consular Affairs legalization and/or destination-embassy endorsement

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.
In depth: the real requirements and why documents get rejected — Notary Public
Written from the competent authority's published rules, not marketing copy.
Many applicants treat the notary stamp as a single, final step. In practice it is the first link in a certification chain that often continues through the Department of Consular Affairs and the destination embassy. The order of that chain is set by the receiving country, and reversing it is the most common reason a file comes back.
Conditions you actually have to clear
The signatory must appear in person with an unexpired passport or national ID card; a scan sent in advance cannot substitute for appearance.
When signing for a company, a recently issued company affidavit and evidence of signing authority consistent with the registered restrictions are required.
The certificate must state the date, the place, the signatory's name, the identification method, and the certifier's registration number; a missing element makes the certificate incomplete abroad.
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.
Real customer questions, answered by our attorneys
Selected from our knowledge base of 3,300+ real questions we have answered.
What are the correct procedures for obtaining authentication at a Royal Thai Embassy abroad?
Consular / Apostille
Quick summary for expats, HR and law firms to "What are the correct procedures for obtaining authentication at a Royal Thai Embassy abroad?" — Typical documents: house registration, birth/marriage/divorce certificates, name-change records, death certificates, single-status letters, police clearance, degrees and transcripts, company affidavits, VAT Por.Por.20, financial statements, powers of attorney and cross-border contracts. Government fee is THB 200 per stamp for the normal service (2–3 business days) and THB 400 per stamp for same-day express (file before 11:30). Our end-to-end agency fee starts at THB 1,500–4,500 per set depending on volume and urgency. Send a photo of the document to LINE @Thainotary and we will quote the chain, cost and timeline within 15 minutes.
Process in brief: (1) assemble the complete file before filing — partial filings lose a queue slot; (2) match every spelling to the passport; (3) file the whole set together so the stamps carry one date; (4) inspect the stamps at the counter; (5) ship with tracked delivery.
What to prepare: the original, a signed certified-true copy, a completed application form, a contact number reachable during office hours, and the name of the destination authority so the correct certification format is applied.
Common pitfall: self-made or machine translations are usually refused — reviewers check the letterhead, the translator's certification wording, and whether every stamp on the original has been rendered.
Practitioner's tip: send us photographs of the documents before work begins. We will confirm the correct chain, an honest timeline, and anything still missing so you do not lose a filing slot.
If the destination changes its rules mid-process, does affidavits and statutory declarations have to start over?
Notary Public
Quick summary for expats to "If the destination changes its rules mid-process, does affidavits and statutory declarations have to start over?" — In Thailand notarial services are performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand — the document is then eligible for MFA legalization or Apostille (in force from 28 February 2027 (entry into force for Thailand)) before use overseas. Standard turnaround is 1 business day; same-day service is available by appointment for straightforward files. Walk-in and mobile-notary appointments both available — call 094-895-8999 to confirm a slot.
Process in brief: (1) decide whether the destination requires an original or a certified true copy; (2) prepare a power of attorney if you cannot attend; (3) translate in the required format; (4) file and monitor the queue; (5) verify whether supporting documents are also required at destination.
What to prepare: the original, a signed certified-true copy, a completed application form, a contact number reachable during office hours, and the name of the destination authority so the correct certification format is applied.
Common pitfall: self-made or machine translations are usually refused — reviewers check the letterhead, the translator's certification wording, and whether every stamp on the original has been rendered.
Practitioner's tip: send us photographs of the documents before work begins. We will confirm the correct chain, an honest timeline, and anything still missing so you do not lose a filing slot.
Who is eligible for legalising a Thai document for use abroad, and which situations are rejected before they even start?
Consular / Apostille
Short answer to "Who is eligible for legalising a Thai document for use abroad, and which situations are rejected before they even start?" — Standard outbound chain: original from the issuing Thai authority → certified English translation → MFA certification of the translation/signature → destination-embassy legalisation in Bangkok (only for non-Apostille countries). Typical documents: house registration, birth/marriage/divorce certificates, name-change records, death certificates, single-status letters, police clearance, degrees and transcripts, company affidavits, VAT Por.Por.20, financial statements, powers of attorney and cross-border contracts. Send a photo of the document to LINE @Thainotary and we will quote the chain, cost and timeline within 15 minutes.
Process in brief: (1) confirm whether the receiving body wants an Apostille or embassy legalisation; (2) obtain the certified original from the issuing authority; (3) translate through an accepted translator; (4) certify translation and signature; (5) keep high-resolution colour scans of every page before the file leaves Thailand.
What to prepare: an intact original that is not torn or laminated, evidence of any name change where the document does not match your current name, a passport copy, and a power of attorney with ID copies of both grantor and agent.
Common pitfall: many destinations accept documents only within 3–6 months of issue or certification. Missing that window means re-issuing and re-certifying the entire set, so plan backwards from the real filing date.
Practitioner's tip: if the same document is needed by several authorities, produce all copies in one round — it saves time and keeps the certification format consistent across the sets.
How long does a notarised a written affidavit for filing with a foreign court stay valid, and what window do receiving authorities usually impose?

What to prepare: the original, a signed certified-true copy, a completed application form, a contact number reachable during office hours, and the name of the destination authority so the correct certification format is applied.
Common pitfall: self-made or machine translations are usually refused — reviewers check the letterhead, the translator's certification wording, and whether every stamp on the original has been rendered.
Practitioner's tip: send us photographs of the documents before work begins. We will confirm the correct chain, an honest timeline, and anything still missing so you do not lose a filing slot.
If the destination refuses legalising a Thai document for use abroad, can notarisation by a Notarial Services Attorney be used instead?

Our end-to-end agency fee starts at THB 1,500–4,500 per set depending on volume and urgency. Send a photo of the document to LINE @Thainotary and we will quote the chain, cost and timeline within 15 minutes.
Process in brief: (1) confirm the original was issued by the competent authority and is still within the accepted validity window; (2) have it translated by a translator the destination accepts; (3) obtain certification of the signature/translation; (4) add destination-embassy legalisation only where Apostille is not accepted; (5) proof names, dates and reference numbers before dispatch.
What to prepare: the full original set, colour scans of every page for translation proofing, an English spelling list for all people and place names, and any extra items listed on the destination authority's own checklist.

How will the Hague Apostille Convention entering into force for Thailand on 28 February 2027 change legalisation for documents sent to India?
Consular / Apostille
Short answer to "How will the Hague Apostille Convention entering into force for Thailand on 28 February 2027 change legalisation for documents sent to India?" — Standard outbound chain: original from the issuing Thai authority → certified English translation → MFA certification of the translation/signature → destination-embassy legalisation in Bangkok (only for non-Apostille countries). Typical documents: house registration, birth/marriage/divorce certificates, name-change records, death certificates, single-status letters, police clearance, degrees and transcripts, company affidavits, VAT Por.Por.20, financial statements, powers of attorney and cross-border contracts. Send a photo of the document to LINE @Thainotary and we will quote the chain, cost and timeline within 15 minutes.
Process in brief: (1) tell us the destination country and purpose so the correct chain is set from day one; (2) re-issue the original if it is older than the destination's limit; (3) translate and proofread twice against the source; (4) certify in the correct order; (5) return the sealed set with a digital copy for your records.
What to prepare: the full original set, colour scans of every page for translation proofing, an English spelling list for all people and place names, and any extra items listed on the destination authority's own checklist.
Common pitfall: never unstaple or re-bind a certified set. Removing the staple is treated as breaking the seal and the destination may reject the whole file; photocopy without dismantling it.
Practitioner's tip: keep colour scans of every certified page. If a courier loses the set, digital copies make re-issue and verification dramatically faster.

In which order should the same-day express counter and a second legalisation at the destination embassy be done so nothing has to be repeated?
Consular / Apostille
Quick summary for expats, HR and law firms to "In which order should the same-day express counter and a second legalisation at the destination embassy be done so nothing has to be repeated?" — Standard outbound chain: original from the issuing Thai authority → certified English translation → MFA certification of the translation/signature → destination-embassy legalisation in Bangkok (only for non-Apostille countries). Typical documents: house registration, birth/marriage/divorce certificates, name-change records, death certificates, single-status letters, police clearance, degrees and transcripts, company affidavits, VAT Por.Por.20, financial statements, powers of attorney and cross-border contracts. Send a photo of the document to LINE @Thainotary and we will quote the chain, cost and timeline within 15 minutes.
Process in brief: (1) confirm the original was issued by the competent authority and is still within the accepted validity window; (2) have it translated by a translator the destination accepts; (3) obtain certification of the signature/translation; (4) add destination-embassy legalisation only where Apostille is not accepted; (5) proof names, dates and reference numbers before dispatch.
What to prepare: the original or a certified extract from the issuing authority, a copy of the holder's ID or passport, a power of attorney if someone files on your behalf, and the exact English spelling of every name as it appears in the passport.
Common pitfall: many destinations accept documents only within 3–6 months of issue or certification. Missing that window means re-issuing and re-certifying the entire set, so plan backwards from the real filing date.
Practitioner's tip: treat the destination authority's own published checklist as the final reference; country-specific rules change, and we will review that checklist with you before filing.
