Technical, business and medical translation, certified for the receiving authority

In short

Specialised translation splits into three groups with different requirements: (1) technical and engineering material such as specifications, manuals and safety standards; (2) business and legal material such as contracts, financial statements and powers of attorney; and (3) medical material such as medical certificates, treatment histories and test results. The deciding factor is the receiving authority. Australian bodies normally expect a translation by a NAATI-certified translator; documents used in Thailand or lodged with an embassy usually need the Department of Consular Affairs to certify the translation, and some private documents must first pass a Notarial Services Attorney. We build a project glossary and review every file twice, but we never guarantee the receiving authority's decision.

Fields we cover

  • Technical and engineering

    Manuals, material specifications, drawings, safety standards and product certificates, where terminology and units must stay consistent across the whole set.

  • Business and legal

    Contracts, financial statements, board resolutions, company certificates and powers of attorney. Binding wording is rendered literally, never interpreted.

  • Medical and health

    Medical certificates, treatment histories, laboratory results, prescriptions and insurance claim documents, keeping drug names, units and reference ranges exactly as in the source.

  • Academic and intellectual property

    Research papers, theses and IP filings, preserving citation structure and field-specific terminology.

How the work runs

  1. Identify the receiving authority first

    The certification format depends on the receiver, not the document type, so we need to know the body, the country and whether paper or digital delivery is required.

  2. Build a project glossary

    Agree terminology, organisation names, job titles and units in advance so every file in the set matches.

  3. Translate and review twice

    A translator in that field drafts, a second reviewer checks substance and figures, then formatting is matched to the source.

  4. Match the certification to the receiver

    NAATI for Australian bodies, Department of Consular Affairs legalisation for use in Thailand or embassy lodgement, and a Notarial Services Attorney for certain private documents.

Where projects go wrong

  • Inconsistent terminology between files in the same submission, which undermines credibility.
  • Errors in figures, units or medical reference ranges.
  • Smoothing contract language until the legal meaning shifts.
  • Leaving seals, signatures or endnotes untranslated.
  • Choosing a certification format the receiving authority does not accept.

Frequently asked questions

Do technical and official documents use the same translators?

Not necessarily. Official records require exact form and authority names; technical work requires field terminology. We assign by field and share a glossary when files belong to one submission.

Do medical documents need a doctor's endorsement?

The source should be issued by a clinician or facility with the practitioner's registration number. The translation is the translator's responsibility; some receivers require additional certification, so check the requirement first.

Can a translated contract be enforced directly?

A translation is supporting material, not a replacement for the original. Courts and counterparties may designate which language version governs, so state this in the contract itself.

Which file formats can I send?

Scanned PDFs, native source files and clearly legible photographs. Send native files for tables or engineering drawings so the layout can be reproduced closely.

Does specialised work take longer?

Usually longer than standard civil records, because of glossary work and substantive review. We quote a working-day range after seeing the actual files.

How is confidentiality handled?

Access is limited to the assigned translator and reviewer, and we can sign a confidentiality agreement on request.

Specialised translation questions

Reviewed August 2026. Requirements change — confirm with the receiving authority before lodging.

What counts as specialised translation?

Work where accuracy depends on subject knowledge rather than language alone: engineering and technical files, contracts and corporate records, financial statements, and clinical or pharmaceutical documents. These are assigned to translators with a track record in that field.

How is terminology kept consistent across a long project?

A glossary is agreed at the start, applied by the translator and checked by a second linguist at review. For repeat clients the glossary is retained so later batches match earlier deliveries.

Can technical drawings and tables be reproduced?

Layout is mirrored as closely as the source allows, including tables, headings, stamps and signature blocks. Where an element cannot be reproduced it is described in a bracketed translator's note rather than silently dropped.

Do medical translations need a certified translator too?

If an Australian body will receive the document, the same certification requirement applies as for any other document. Clinical accuracy is a separate matter handled by assigning a translator experienced in medical text.

How is confidentiality handled for commercial documents?

Files are shared only with the translator and reviewer working on the job, and a confidentiality undertaking can be signed before files are sent if your side requires one.

What counts as a specialised translation?

Material where a wrong term changes the meaning: medical records, pharmaceutical documentation, engineering specifications, patents, financial statements and litigation documents. These are matched to a translator with subject knowledge, not just the language pair.

Can I supply my own glossary?

Yes, and it is strongly encouraged for technical and corporate work. A client glossary of product names, job titles and internal terminology is applied consistently across the set and kept for future jobs so later documents match earlier ones.

How is confidentiality handled for sensitive documents?

Files are shared only with the translator and reviewer assigned to the job, transferred over the channel you choose, and not published or reused. Where your organisation requires its own confidentiality undertaking, send it with the request.
