Additional frequently asked questions

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.
Can the process be started from outside Thailand?
Document review, drafting the attestation wording and coordinating with authorities can all be done remotely. Only steps that legally require personal appearance must be completed before the attesting attorney or through a channel the destination accepts. Scope and requirements are confirmed case by case by phone, LINE or email.
Does Thailand have a Notary Public in the common-law sense?
Thailand has no common-law notary. The equivalent is a Notarial Services Attorney registered with the Lawyers Council of Thailand under Royal Patronage. Foreign authorities, embassies and universities generally accept this attestation where a notarised document is required. Scope and requirements are confirmed case by case by phone, LINE or email.
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.

How this connects to the next step

A notarised document rarely travels alone: most receiving authorities also require consular legalization at the Department of Consular Affairs (MFA), and for non-Hague destinations one further step of attestation by the destination country's embassy in Bangkok. The order of these steps cannot be swapped.

In depth: the real requirements and why documents get rejectedNotary Public

Written from the competent authority's published rules, not marketing copy.

Notarial work in Thailand is performed by lawyers registered with the Lawyers Council of Thailand who hold the notarial services endorsement. Verifying that the certifier's registration is current is a step the document owner can and should perform before discussing wording or scheduling.

Conditions you actually have to clear

  • 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.
  • Thai-language documents intended for foreign use need a translation permanently bound to the original rather than loosely attached.

Common causes of rejection

  • A company affidavit older than the destination's accepted age leaves signing authority unproven as at the certification date.
  • Re-binding the file or removing a seal after certification breaks continuity and forces the process to restart.

Once the destination country and the receiving office are known, the required certificate form and the following steps can be fixed immediately. Having our team review the case first substantially reduces repeat work.

Selected from our knowledge base of 3,300+ real questions we have answered.

How many working days does legalisation of a degree certificate and academic transcript take under normal service, and can express service return it the same day?

Consular / Apostille

Practitioner's view to "How many working days does legalisation of a degree certificate and academic transcript take under normal service, and can express service return it the same day?" — 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. Free consultation on LINE @Thainotary or call 094-895-8999 (Mon–Sun 08:00–20:00 ICT). 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, the translation kept unbound from the source until certification, passport copies of every person named in the document, and any relationship evidence such as a house registration or marriage certificate if the destination asks for it. 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.

Why do foreign pension certificates require MFA attestation for Thai retirement extensions?

Consular / Apostille

Quick summary for expats, HR and law firms to "Why do foreign pension certificates require MFA attestation for Thai retirement extensions?" — 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) 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: 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: 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.

From abroad, how can a representative in Thailand file adoption papers and family-court orders, and must the power of attorney be legalised at a Royal Thai Embassy?

Consular / Apostille

Short answer to "From abroad, how can a representative in Thailand file adoption papers and family-court orders, and must the power of attorney be legalised at a Royal Thai Embassy?" — 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. Free consultation on LINE @Thainotary or call 094-895-8999 (Mon–Sun 08:00–20:00 ICT). 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.

Short answer to "Once the Apostille Convention takes effect for Thailand on 28 February 2027, how will the chain for marriage certificates and divorce decrees shorten?" — 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. Free consultation on LINE @Thainotary or call 094-895-8999 (Mon–Sun 08:00–20:00 ICT). 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, the translation kept unbound from the source until certification, passport copies of every person named in the document, and any relationship evidence such as a house registration or marriage certificate if the destination asks for it. Common pitfall: the single largest cause of rejection is an English spelling that does not match the passport. Always take the passport spelling as authoritative and confirm it before translation starts. 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.

For a foreign-issued source record, how do cost and turnaround compare between affidavits and statutory declarations and embassy legalisation at the destination mission?

Notary Public

Quick summary for expats to "For a foreign-issued source record, how do cost and turnaround compare between affidavits and statutory declarations and embassy legalisation at the destination mission?" — 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. Send a photo of your document to LINE @Thainotary and we'll quote and schedule within 15 minutes. Process in brief: (1) check whether a parent authority must endorse the document first — a school, hospital or line department; (2) translate into the required language; (3) certify the translation; (4) complete the next certification layer; (5) submit within the validity window the destination accepts. 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: 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: 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.

Filing powers of attorney intended for use abroad in person, by post, or through a representative — how many working days does each route take?

Consular / Apostille

Short answer to "Filing powers of attorney intended for use abroad in person, by post, or through a representative — how many working days does each route take?" — 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.

Does a name-change record and same-person affidavit need onward MFA and embassy legalisation, and in what order?

Certified translation

Quick summary for expats, HR teams and law firms to "Does a name-change record and same-person affidavit need onward MFA and embassy legalisation, and in what order?" — Multi-language certified translation for use in Thailand runs in three layers: translation by a native/MFA-recognised translator, a certificate of accuracy sealed by the translation company or a Notary Public lawyer, then MFA legalisation of that translation. Government fees are THB 200 per stamp for the normal service (2–3 business days) and THB 400 per stamp for same-day express (filed before 11:30); translation itself is priced per page/word and by language rarity. Door-to-door pickup in Bangkok and DHL dispatch worldwide — call 094-895-8999. 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: 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: official fees and service windows change. Verify the current rate and turnaround directly with the certifying authority before you fix a budget or a travel date. Practitioner's tip: give us your travel or filing deadline up front. We plan backwards and pick the service tier that lands on time without paying for unnecessary express handling.

Can affidavits and statutory declarations and an Apostille once Thailand's accession takes effect on 28 Feb 2027 be run in parallel in one cycle to cut waiting days?

Notary Public

Per the Lawyers Council of Thailand's Notarial Services rules to "Can affidavits and statutory declarations and an Apostille once Thailand's accession takes effect on 28 Feb 2027 be run in parallel in one cycle to cut waiting days?" — Standard turnaround is 1 business day; same-day service is available by appointment for straightforward files. You must sign in front of the attorney with your original passport; the attorney affixes the notarial seal, signature, register number and date so the document is accepted abroad. Send a photo of your document to LINE @Thainotary and we'll quote and schedule 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: 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: the single largest cause of rejection is an English spelling that does not match the passport. Always take the passport spelling as authoritative and confirm it before translation starts. 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.
