Frequently asked questions
What Types of Document Certification Are Available?
There are several types of document certification and translation certification, depending on the purpose of use and the requirements of the receiving authority. Common types include:
- Translation certification by a translator or translation company
- Notarial certification by a Notarial Services Attorney
- Document legalization by the Department of Consular Affairs, Ministry of Foreign Affairs of Thailand
- Certification by an embassy or consulate
- Certification by the authority that originally issued the document
The appropriate type of certification depends on the requirements of the receiving authority. Before proceeding with document translation and legalization, it is recommended to confirm with the relevant authority which type of certification is required.
How does standard translation differ from certified translation?
Standard translation converts your document into another language. Certified translation adds a signed statement or company certification that confirms the translation is accurate and complete. You usually need certified translation for official use, such as visas, courts, schools, and government offices.
What Is Translation Certification by a Translator or Translation Company?
Translation certification by a translator or translation company is a process in which the translator or translation service provider confirms that the translation has been prepared based on the original document or a copy provided by the client and that the translated content accurately reflects the source document to the best of the translator’s ability.
However, some authorities may not accept translator or translation company certification alone and may require additional certification or legalization by another authorized authority.
Therefore, clients should check the requirements of the receiving authority before requesting certified translation services.
What Is Notarial Certification?
Notarial certification in Thailand is a certification performed by a lawyer who has completed the required training and has been authorized by the Lawyers Council of Thailand to provide certain notarial services.
Depending on the nature of the document and the requirements of the receiving authority, notarial certification may include:
- Certification of signatures
- Certification of copies of documents
- Certification that a person signed a document in the presence of the Notarial Services Attorney
The scope of notarial services depends on the type of document and the specific requirements of the authority or organization where the document will be submitted.
When do you need legalization from the Department of Consular Affairs?
You may need legalization when a receiving authority asks for official validation of your document for use in Thailand or overseas. The exact steps depend on the document type and where you will submit it. In many cases, translation comes first, followed by any required notarization or legalization.
What steps are usually needed to use a foreign document in Thailand?
You usually start by checking the requirements of the agency that will receive the document. Then you translate it, and complete any needed certification, notarization, or legalization. The exact process depends on the document type and the receiving authority.
How Can Thai Documents Be Used Overseas?
Before using a Thai document abroad, it is important to determine the language into which the document must be translated and which authorities must certify or legalize the document.
Depending on the destination country and the type of document, the process may include:
- Certification of the original document
- Translation of the document
- Legalization by the Department of Consular Affairs, Ministry of Foreign Affairs of Thailand
- Certification or legalization by the embassy or consulate of the destination country
The required procedure varies depending on the destination country, document type, and requirements of the receiving authority.
Which documents usually need translation and certification?
Common examples include passports, birth certificates, marriage certificates, academic transcripts, diplomas, company registration records, contracts, court papers, and immigration documents. The exact requirement depends on where you submit the document.
Do you always need to provide the original document for translation?
Not always. A clear scan or photo is often enough for translation. If you need certification, notarization, or legalization, you may need to show the original document later. You should confirm the required format before you place your order.
How Is Court Document Translation Different from General Translation, and Why Should It Be Handled by Professionals?
Documents intended for submission to a court require a high level of accuracy, completeness, and consistency with the original document. Court translations should not summarize, omit, alter, or inaccurately interpret the content of the source document.
The wording of a translated document may directly affect the consideration of evidence and, in some cases, the outcome of legal proceedings. Errors in translation, inappropriate legal terminology, or discrepancies between the translation and the original document may affect the credibility of the document, allow the opposing party to challenge its accuracy, or prevent the court from fully understanding the intended meaning of the original document.
Our team has experience in legal document translation and court document translation for various types of legal proceedings. Our translation process includes review by lawyers and relevant language specialists to ensure that the translated documents are accurate, complete, consistent with the original, and appropriate for use in court proceedings.
For documents intended for use in litigation, professional legal translation and careful document review are essential to minimize the risk of translation errors and ensure that the document properly communicates the meaning of the original.
How do I get a quotation for my document?
