ISO 18587 LinguaVox provides certified translation services for companies, public bodies, law firms, universities, marketing teams and private clients who need multilingual content handled with precision, confidentiality and a clear delivery workflow. The company has worked in translation since 2000 and manages projects in more than 150 languages.
Certified translation is usually requested when a translated document has to be submitted to an authority, institution, university, employer, court, immigration body, bank or corporate department. The exact certification format depends on the destination country, the receiving organisation and the type of procedure.
Specialist certified translation services
This service is intended for documents that have to be submitted to public authorities, courts, universities, consulates, notaries, banks or foreign institutions. Each request is assessed by source language, target language, country of use, subject matter, file format and deadline. A legal document, an industrial manual, a website, a medical report and an audiovisual script should not be treated as the same kind of task.
The workflow may include translation, independent revision, terminology control, file preparation, delivery checks and multilingual project coordination. Not every project needs the same level of intervention, but every project should have a clear scope before work begins.
The word "certified" is not used identically in every country. In some cases, a certificate of accuracy from the translator or agency is enough. In others, the receiving body may require a sworn translator, a notarial step, a physical copy, an electronic signature, an apostille or legalisation. LinguaVox can prepare the translation, but the client should always confirm the specific requirements of the authority receiving the document.
Typical documents and files
Common materials include birth, marriage and death certificates, criminal record certificates, academic transcripts, university degrees, diplomas, powers of attorney, court decisions, company deeds, immigration files, passports, residence permits and official identification documents. Corporate clients may also need certified translations of articles of association, tax certificates, commercial register extracts, board resolutions, bank documents, public tender material or compliance records.
We can also assess less standard files once the client explains the purpose of the translation, the target audience, the required format and any authority or platform that will receive the final version.
When a document contains technical, legal, medical, financial, scientific or commercial terminology, the assignment is based on more than the language pair. The project manager weighs subject-matter knowledge, any reference material, approved terminology and the level of risk involved.
Workflow and quality checks
The process starts with file analysis. After the quote is approved, the project is assigned to a suitable translator or reviewer and instructions are prepared. Larger projects may need a glossary, file engineering, priorities by document type or staged deliveries.
Revision is not a last-minute correction. It checks meaning, terminology, numbers, names, formatting and fitness for the target market. When the service is contracted under an ISO 17100 workflow, bilingual revision by a second qualified person is part of the process.
For official files, the final checks also focus on names, dates, stamps, signatures, seals, handwritten notes, institutional names and page order. These elements can matter as much as the main text, because the receiving authority may compare the translation with the source document.
Certified, sworn, notarised and legalised translations
Certified translation should not be confused with sworn translation in Spain, notarised translation in some jurisdictions or legalisation of a document. A certified translation usually carries a declaration confirming that the translation is accurate and complete. A sworn translation in Spain is signed and stamped by a sworn translator appointed by the Spanish Ministry of Foreign Affairs. Notarisation and apostille are separate formalities, and may concern the document, the translator's declaration or another administrative step.
Because requirements vary, the safest approach is to identify the receiving country and authority before ordering. This avoids paying for a format that is not required, or receiving a digital copy when a paper version is needed.
Requesting a reliable quote
The most reliable way to request a quote is to send the original files and explain the language pair, deadline, country of use and delivery format. If certification, DTP, terminology management, urgent delivery or several target languages are involved, those elements should be assessed from the beginning.
LinguaVox prepares quotations with the real workflow in mind. Word count matters, but so do the file format, the intended use, the review requirements, the subject matter and whether the translation will be published, submitted to an authority or used in a business-critical process.
Frequently asked questions
What is included in certified translation services?
The service can include file review, professional translation, terminology checks, a certificate or statement of accuracy and delivery in the agreed format. Independent revision, layout work, printed delivery or multilingual coordination can be added when the project requires them.
Are certified and sworn translations the same?
Not always. "Certified translation" is a broad term in English, while "sworn translation" refers to specific systems such as the Spanish sworn translator system. The correct format depends on the destination country and the authority receiving the document.
What documents are commonly certified?
Common documents include civil certificates, academic records, criminal record certificates, powers of attorney, company deeds, immigration files, court documents and corporate records. If the receiving body has issued specific instructions, send them with the source files.
Can a certified translation be delivered digitally?
In many cases, yes, but it depends on the receiving authority. Some bodies accept secure PDF delivery or electronic signatures, while others may require a printed copy, an original signature, a stamp, a notarial step or another administrative format.
What information do you need to quote a certified translation?
Please send the complete document, the source and target languages, the destination country, the receiving authority, the deadline and the preferred delivery format. If the document contains stamps, handwritten notes, poor scans or several pages, send the full file rather than an extract.
