Notarial Services & International Documents
Notarial Services Attorney, certified translation and legalisation for use abroad

This practice covers certification by a Notarial Services Attorney, certified translation, and legalisation of documents so they can be used abroad — or so foreign documents can be used in Thailand. The order of the steps is what usually goes wrong: the receiving authority's requirement is confirmed first, then translation, certification and legalisation follow in the sequence that authority accepts.

Pitfalls and common misunderstandings
Confirm the requirement before starting
Different countries and institutions accept different forms and sequences. Starting without the receiving authority's requirement in writing is the main reason documents come back and have to be redone.
Sequence errors cannot be patched
Translating after certification, or legalising before the certification the authority expects, usually means repeating steps from the beginning. The order is set at the outset for that reason.
Certification confirms form, not the underlying facts
A Notarial Services Attorney certifies matters such as a signature or that a copy corresponds to the original. It is not a verification of the truth of the document's contents, and no one should represent it that way.
Notarial certification, certified translation and legalisation
Most files need more than one of these. This shows what each step actually does.
| Point | Notarial certification | Certified translation | Legalisation |
|---|---|---|---|
| What it does | Certifies a signature, a copy or a declaration | Produces a translation with a certification of accuracy | Confirms the document for official use in another jurisdiction |
| Who performs it | A Notarial Services Attorney | A qualified translator, certified as required | The authority or channel the destination accepts |
| Needed when | The receiving party requires certified signatures or copies | The document is not in the required language | The destination requires official confirmation |
| Typical inputs | Original document and the signatory's identification | The source document and the target language | The certified and translated document |
| Common pitfall | Certifying a document the destination does not accept in that form | Translating before the final version is confirmed | Doing it before the certification step it depends on |
We confirm the requirement of the specific receiving authority before beginning, so the sequence is right the first time.
Hand the whole matter to the firm
Because translation, notarial certification and legalisation are handled in the same office, the file moves through the steps in the correct order without being passed between separate providers. Fees are quoted per document set after we see the requirement.
Notarial Services & International Documents: frequently asked questions
- What does a Notarial Services Attorney in Thailand do?
- A lawyer licensed as a Notarial Services Attorney certifies matters such as a signature, that a copy corresponds to an original, or a declaration made before them. It confirms form and execution rather than verifying that the document's contents are true.
- Which comes first, translation or certification?
- It depends on the receiving authority. Some require the original certified first and then translated; others require a certified translation before legalisation. Because reversing the order usually means redoing the work, we confirm the requirement before starting.
- Does Thailand issue an apostille?
- Thailand's legalisation of documents for overseas use runs through its own channel rather than an apostille under the Hague Convention on Legalisation. Which form your destination accepts should be confirmed with that receiving authority before the file is prepared.
- Can a power of attorney be signed here and used abroad?
- Yes, and it commonly requires certification of the signature, a certified translation into the destination language, and legalisation. The wording also has to satisfy the receiving institution, so send their template or requirement if you have one.
- How can a foreign document be used in Thailand?
- Usually it is certified in its country of origin, then translated into Thai with the translation certified, and legalised through the route the Thai receiving authority requires. Different Thai authorities can require slightly different forms.
- How long does the whole process take?
- It depends on the document type, the destination and the channels involved, and parts of it are outside the firm's control. We tell you which steps have external timelines so you can plan submission deadlines with a margin.
- Do I have to attend in person?
- Certification of your own signature requires you to sign before the Notarial Services Attorney with identification. Certification of copies and translation work can often proceed without you present once the originals are available.
- My document was rejected abroad. Can it be fixed?
- Often yes, but it usually means repeating the steps in the correct sequence. Send the rejection notice, because it normally states exactly which form the receiving authority requires, which is what determines the corrected route.
