What the reviewer examines
The precise scope should be agreed for the document. It may include omissions, mistranslations, inconsistent terms, figures, references, grammar and register. In a machinery manual, safety warnings and part names deserve attention. In an agreement, a negation, exception or defined term can change the reading of a clause. If you need a separate report of findings as well as corrected text, say so when requesting a quotation.
An existing translation can read naturally and still be wrong. A clause might assign a duty to the wrong party while sounding entirely plausible in English. That is why legal translation and technical translation require subject-aware review. A generic list of substitutions cannot determine whether an expression has the right function in the document.
Bilingual review and monolingual proofreading
Bilingual review checks the target against its source. Monolingual proofreading improves the target text's spelling, grammar and style without establishing whether it faithfully represents another document. Both can be useful, but they answer different questions. If your concern is missing information or altered meaning, provide both files. If the text was written directly in the final language, a monolingual edit may be the appropriate service.

Tell us how much intervention you want. You may need tracked corrections, comments explaining material errors or a clean publication copy. If the company has a style guide, a preferred tone or approved terms, send them. A review should distinguish an objective mistake from a legitimate stylistic alternative rather than presenting every preference as an error.
When machine translation is involved
If the existing target is machine output, post-editing may be the right workflow. It needs an agreed outcome, a view of the raw output and an understanding of the source material. Some checks overlap with review, but the effort cannot be priced from the label alone. If the output contains repeated omissions or distorted sentences, retranslating particular sections may make more sense than repairing each one.
For a website, localisation may also require checking the text on screen. A sentence can be correct in a spreadsheet yet be cut off in a button. For a brochure or report, multilingual typesetting can ensure that corrections remain visible and attached to the right figures after layout.
Preparing the material
Supply the source and translation in matching, clearly named versions. Editable files make tracked changes easier. Add glossaries, earlier client comments and any passages that have already received formal approval. Where a project contains several documents, identify which target corresponds to which source; comparing files from different revisions can produce misleading findings. We can agree whether the return should contain tracked changes, a clean copy or both.

Where a term allows several defensible choices, the client's product or procedure may decide which one to use. Recording that decision prevents conflicting corrections across chapters. We distinguish a problem inherited from the source from an error introduced in translation, so the author of the original can address it appropriately.
The source version matters particularly for clinical and financial work. Medical translation can contain sensitive values and negative findings; financial translation connects figures across tables and commentary. A reviewer needs to trace those relationships, not just read isolated sentences.
Deciding whether review is worthwhile
Volume, languages, subject, initial quality and the agreed depth all affect the quotation. A representative sample can show whether review is proportionate or whether some passages need a new translation. Our quality approach starts with the intended use and ends with a usable file, not merely a cleaned-up line of text. See the wider translation services or send the files through the quote form.
Frequently asked questions
Can I send only the translated file?
We could consider a monolingual edit, but bilingual review needs the source as well. Without it, omissions and changes of meaning cannot be checked. Please identify matching versions of the two files.
Do you review work translated elsewhere?
We can assess an existing translation regardless of who produced it. Its origin does not establish its quality. A sample and the source allow us to determine whether review is a useful route and what scope is needed.
Can I receive tracked changes?
Yes, that can be agreed according to the file format. Tell us whether you also need a clean copy or comments explaining significant findings. These deliverables should be specified in the quotation.
How does review differ from post-editing?
Post-editing starts from machine output and is defined by the intended result and intervention required. Review evaluates an existing target against its source under an agreed scope. We need to see the material to select and price the workflow.
Does reviewing a file make it a sworn translation?
No. Spanish sworn translation has separate professional authorisation and certification requirements. Review cannot grant that status to an ordinary document. Check what the receiving body requires before ordering formal work.
