Notary for Visa Applications
Which visa documents need notarization?
Commonly: consent letters for children travelling, sponsor letters, affidavits, bank statements, and true copies of passports and degrees. Requirements depend on the embassy and visa type. Check the embassy's checklist before you notarize anything.

Bring the current visa checklist and the exact form before arranging certification. Our Bangkok (Lat Phrao 95) and Khon Kaen teams can help identify the document, signature and translation work requested; the receiving authority decides what it accepts.
Common visa notarizations
- ✓ Passport copies where certified copies are requested
- ✓ Parental consent using the recipient's wording
- ✓ Sponsor declarations with the required witness category
- ✓ Relationship declarations on the prescribed form
- ✓ Birth or marriage record copies, if required
- ✓ Supporting document translations in the accepted format
Before you sign a country-specific form
A visa checklist does not automatically require every supporting document to be notarized. A German Verpflichtungserklärung is an official undertaking, not an ordinary invitation made equivalent by a Thai notarial stamp. Australian and Canadian declarations may specify who can witness them. We check the instructions rather than promise that one Thai certificate fits every country.
For an initial enquiry, send the destination, visa type, form or checklist and intended submission date through LINE. Bring original identification and any originals needed for copy certification to the appointment; do not pre-sign unless the form expressly permits it.
FAQ
- Does every visa application require notarized documents?
- No. Use the current checklist for the destination and visa category. Some recipients accept ordinary copies or bank-issued records; others specify certified copies, a declaration or a particular witness. Do not notarize a whole file by default.
- Can a Thai notarial attorney witness every foreign declaration?
- Not automatically. The prescribed form may restrict the witness category. Confirm that the recipient accepts a Thai Notarial Services Attorney before signing, particularly for statutory declarations and official sponsorship undertakings.
- What should I bring to a visa notarial appointment?
- Bring the checklist, unsigned form, original photo identification and originals for any true-copy certification. Parental consent may also require relationship or parental-authority evidence. We confirm the document list before arranging an appointment.
- Is legalization or translation always needed after notarization?
- No. Follow the recipient's instructions. Where an outbound Thai document needs consular legalization before 28 February 2027, check the Thai MFA and destination embassy route. A notarial stamp does not guarantee visa approval.
- How do I obtain a quote?
- Send the visa category, destination and requested document list for a free initial enquiry. Certification, translation and any authority charges are scoped after review; legal advice and document work are not advertised as free.

Thailand has no notary public — it has Notarial Services Attorneys
Applicants raised in common-law jurisdictions arrive expecting a notary public in the English or American sense. Thailand does not have that office. What exists is the Notarial Services Attorney, a Thai lawyer licensed by the Lawyers Council of Thailand under its notarial services regulation and entitled to attest signatures, certify copies as true to the original, administer oaths and affirmations, and witness the execution of documents. The credential is a lawyer's licence with a notarial endorsement, and it carries a registration number that the receiving authority can check.
That distinction matters for visa work because the phrase on the checklist is usually 'notarised'. A consular officer in Bangkok knows what a Thai notarial attestation looks like. An overseas recipient may specify a particular witness or certificate. A clearly drafted English attestation states what was certified and the attorney's registration, but does not cure a witness category the recipient does not accept.
Notarisation is also not legalisation. A notarised copy is a statement about what the attorney saw. Where the receiving country needs a chain of authentication, the notarised document then goes to the Department of Consular Affairs and, until 28 February 2027 when the Apostille Convention takes effect for Thailand, on to the destination embassy in Bangkok.
Which visa documents actually need notarisation
| Document | Typical destination requirement | What the attestation must say |
|---|---|---|
| Passport copy | Only where the applicable checklist requests certification | Certified a true copy of the original produced to the attorney |
| Bank statement copy | Study and visitor applications | True copy; the bank's own certification is preferred where obtainable |
| Sponsorship or affidavit of support | Student and family visit visas | Signature attested; deponent identified by passport |
| Parental consent for a minor travelling | Where the travel authority requests witnessed consent | Follow the required signatories and provide parental-authority evidence |
| Property or company ownership evidence | Visitor visas showing ties | True copy of the land office or DBD extract, not of a photocopy |
| Statutory declaration of relationship | Family visit and partner visas | Oath or affirmation administered, wording matching the destination's prescribed form |
How a session runs and what to bring
- Send drafts before the appointment: Affidavit and declaration wording should be reviewed against the destination's prescribed form first. This helps identify any wording or witness issue before attendance.
- Bring originals, not copies: A true-copy certification requires the attorney to see the original. A copy of a copy cannot be certified, however clear it is.
- Bring photographic identification for every signatory: Passports for foreign nationals, Thai ID cards for Thai signatories. The attestation records the identification relied on.
- Sign in the attorney's presence: A signature already on the page can only be acknowledged, which some destinations do not accept in place of attestation.
- Decide the onward chain at the same appointment: If MFA certification and embassy legalisation will be needed, the document set is assembled differently from the outset.
Language, translation and the order of operations
Where the underlying document is in Thai, ask the recipient which translation format it accepts and whether the original, translation or translator's declaration needs certification. Translation, notarial attestation and consular legalisation are separate acts; the sequence follows the recipient's checklist, not a universal four-step rule.
For destinations that require the translation itself to be certified by the Department of Consular Affairs, the MFA has its own formatting expectations and will check the transliteration of names against the passport. We fix the transliteration once, at the start, and use it consistently across every document in the file, because a first name spelled two ways across a bundle reads as a discrepancy rather than a typo.
Common mistakes and how we avoid them
More questions we are asked
- Is a Thai notarial attestation accepted internationally?
- Acceptance is decided by the receiving authority. Check its witness category, certificate wording and authentication requirements before ordering a Thai notarial attestation.
- Can you notarise a document I email over?
- A true-copy certification requires sight of the original. Signature attestation requires the signatory to attend. Drafting and review can be done remotely beforehand.
- Do both parents need to attend for a minor's travel consent?
- Both signatures normally need attesting. Where one parent has sole parental power, bring the court order or registration proving it and we draft accordingly.
- Will an apostille replace this in 2027?
- The Convention enters into force for Thailand on 28 February 2027. Check the HCCH status, whether it applies between Thailand and the destination, and the document category. An Apostille authenticates origin; it does not guarantee acceptance of the contents.
- How long is a notarised document valid?
- A certificate records the act on its stated date. The receiving authority may impose its own document-age requirement; confirm that window before arranging certification.

Frequently asked questions
- Does Thailand have notaries public?
- Thailand uses Notarial Services Attorneys registered with the Lawyers Council of Thailand for notarial acts within their permitted scope. Acceptance abroad depends on the recipient. Ask which certifier, wording and any additional authentication it requires; notarial certification is not the same as an Apostille.
- What documents can a Notarial Services Attorney certify?
- Commonly certified items include signatures on powers of attorney, affidavits and statutory declarations, certified true copies of passports and corporate documents, company resolutions and share transfer forms, sponsorship and consent letters, and the identity of a signatory for foreign banks, universities and courts. The attorney certifies the signing act or copy fidelity — not the truth of the content.
- Do I have to sign in person?
- Yes. The attorney must see the signatory in person together with the original passport or Thai ID before certifying a signature, which is the core safeguard of the service. Remote or scanned signatures cannot be certified. Mobile appointments at your office, condominium lobby or a nearby café are available if you cannot come to ours.
- How much does notarial certification cost and how fast is it?
- Attorney notarial certification starts at the current official rate per document, with the final price depending on the number of documents, signatories and whether the appointment is mobile or out of hours. The certification itself is completed during the appointment; only the subsequent MFA and embassy steps add working days.
