Practical playbook: Multi-language Certified Translation

Translation for official use must be complete, faithful to the source layout, and issued with a certification the receiving authority accepts — plus a legalisation chain where the document crosses borders.

Documents to prepare

  • Complete scan of every page, including reverse sides and seals
  • Passport spelling reference for all names
  • Any glossary or previous translations for consistency
  • The receiving authority's translation requirements

Steps and method

  1. 1. Requirement check

    Confirm the target language, certification type and whether legalisation is needed.

    Typical timeframe: 1 day

  2. 2. Translation and review

    Translate the full document and run an independent review of names, dates and figures.

    Typical timeframe: 1–5 business days

  3. 3. Certification

    Issue with the translator's certification, and notarisation where the recipient requires it.

    Typical timeframe: 1–2 business days

  4. 4. Legalisation chain

    Add MFA legalisation plus Apostille or embassy legalisation depending on the destination.

    Typical timeframe: 3–15 business days

Consultant tips

  • Give the destination country up front — certification requirements differ sharply between them.
  • Check whether the recipient accepts digital signatures or insists on wet-ink copies.

Pitfalls to avoid

  • Omitting stamps, footnotes or reverse-side text makes the translation incomplete.
  • Machine translation without a responsible certifier is not accepted for official use.

Company-certified translation vs consular-certified translation

The receiving party decides which certification is accepted — check before ordering.

Doing it yourself vs having iVC manage the whole process

Both routes are valid. They differ in the time you spend, the risk of documents being returned, and whether an adviser reviews everything before submission.

We work as advisers, not just a document courier

More than 15 years of casework (since 2011) in translation, certification and visa document preparation shows us the patterns behind repeated rejections, so we plan around them from the start.

Case assessment first
We review the profile, destination country and receiving authority before recommending a certification route.
A document plan per person
We sequence what must be re-issued, translated first, and certified in which order.
Risks flagged early
We point out the usual rejection triggers, such as name spelling that differs from the passport or document age limits.
Follow-through to the end
Regular progress updates, and immediate options if the authority requests more documents.
Advice after completion
The same set is often reused in the next step; we check whether it still qualifies or needs re-issuing.

If you would rather not chase each step yourself, send the case details for an assessment first, then decide.
