Notary Public
Notary Public in Thailand: required documents, step-by-step process, professional tips, common pitfalls and how our 15+ year consulting team handles the whole chain for you.
Documents to prepare
- Original passport or Thai ID of every signatory (must be shown in person)
- The full document to be notarised, all pages, unsigned
- The original document when a certified true copy is required
- Company affidavit issued within 6 months plus company seal (for corporate signatories)
- Any wording or form template required by the receiving party
Step-by-step process
- Pre-check the document — Send a scan; a consultant confirms which notarial act the receiving party actually needs.
- Choose the certificate wording — Wording is matched to what the university, court, bank or foreign authority accepts.
- Book the attorney — At our office, or on-site for corporate clients.
- Sign before the attorney — Signatories show original ID and sign in the attorney's presence.
- Seal and register — The Notarial Services Attorney signs, seals and records the act in the register.
- Onward legalisation (if used abroad) — Filed with the MFA and the destination embassy in the correct order.
- Delivery and archive — Collected or couriered with tracking; a scanned copy is retained for later verification.
Common pitfalls to avoid
- A Notarial Services Attorney must witness the signature live; a pre-signed document cannot have its signature notarised.
- Thai notarisation is not a Common Law Notary Public; many destinations still require MFA legalisation afterwards.
- A company affidavit older than six months is usually rejected as proof of signing authority.
- Jurat, acknowledgement and certified true copy are not interchangeable — pick the act the receiving party names.
- Incomplete page sets or unreadable copies will not be certified.
Compare your options
| Option | Best for | Watch out for |
|---|---|---|
| Thai Notarial Services Attorney | Documents where the receiver only needs a signature witness, certified copy or affidavit | The signer must sign in front of the attorney; pre-signed papers do not qualify |
| MFA legalisation after notarisation | Documents filed with foreign government bodies or embassies | Sequence is fixed: translate, certify, legalise, then embassy |
| A Notary Public in the destination country | When the signer is already abroad, or the receiver insists on Common Law form | Travel and time cost; Thai documents usually need translation first |
Not sure which route fits your case? Send us the documents and the receiving authority's name — our consultants will confirm the correct chain before you spend time on any office visit.
Consultant tips
- Tell us the receiving authority first — each notarial act suits a different purpose.
- Bring the original passport or Thai ID; a copy alone cannot support signature witnessing.
- For company files, obtain a fresh affidavit within three months of the appointment.
- Send photos of every page in advance so we can pre-check before you travel to the office.
- If the document goes abroad, plan MFA legalisation and the embassy step from day one.

Frequently asked questions and answers
What exactly does Notary Public cover?
Notary Public covers document preparation, translation where required, certification by the competent authority and — when the document is used abroad — legalisation through the Ministry of Foreign Affairs and the destination embassy. Our consultants confirm the exact chain for your specific document before you start.
Which documents do I need to prepare first?
Original passport or Thai ID of every signatory (must be shown in person) • The full document to be notarised, all pages, unsigned • The original document when a certified true copy is required • Company affidavit issued within 6 months plus company seal (for corporate signatories) • Any wording or form template required by the receiving party
How long does the whole process take?
In-office certification is usually same-day. Ministry legalisation and embassy steps depend on each authority's queue, so we give a written timeline per case after reviewing your documents.
Can you handle everything for me?
Yes. This is the option most clients choose: you send the documents, our consulting team maps the requirements, prepares, certifies, files and delivers, and we stay available if the receiving authority asks for anything more.
Any tips that make the process faster?
Tell us the receiving authority first — each notarial act suits a different purpose. • Bring the original passport or Thai ID; a copy alone cannot support signature witnessing. • For company files, obtain a fresh affidavit within three months of the appointment. • Send photos of every page in advance so we can pre-check before you travel to the office. • If the document goes abroad, plan MFA legalisation and the embassy step from day one.
How much does it cost?
Fees depend on document type, language and the authorities involved. Contact our team via phone, LINE or email for a written quotation before any work starts.
Are you only a filing agency?
No. With 15+ years of practice we act as consultants first: we advise on which route is valid, what the receiving body will accept, and which steps you can safely skip — then execute the work for you.
What happens if the authority rejects a document?
We pre-check against the destination checklist to avoid it. If a rejection still happens on work we handled, we correct and refile it as part of the same engagement.
Do you serve clients outside Bangkok or overseas?
Yes — nationwide in Thailand and for Thai nationals and foreign nationals abroad, using couriered originals and digital pre-checks.
Prefer not to handle this yourself?
Our consulting team has advised on document chains for over 15 years. Send your documents and we handle preparation, certification, filing and delivery end to end — and advise you at every decision point.
