Plain-English definitions of 70 terms used across UK visa applications, certified translation, immigration, and legal authentication. Cross-linked to the relevant document, language, and service pages.
Terminology specific to certified, sworn, and official document translation.
A translation accompanied by a signed statement from the translator confirming it is a true and accurate representation of the original. UKVI, HMCTS, USCIS, and most UK regulators accept certified translations without further notarisation. The certification statement must include the translator’s name, qualifications, contact details, and the date of translation.
A certified translation that has been signed in front of a notary public, who verifies the translator’s identity (not the accuracy of the translation). Not required for standard UK visa applications, but sometimes requested for documents being sent overseas or used in jurisdictions that operate sworn-translator systems.
A translation produced by a translator who has been sworn in by a court and is on a public register of authorised translators (common in Spain, France, Germany, Italy, and Poland). The UK does not operate a sworn-translator system; the UK equivalent for legal purposes is a certified translation with a statement of truth. Where a document has to be submitted in Germany or Spain, we supply a sworn translation (beglaubigte Übersetzung / traducción jurada) — select the country on the quote form.
The signed declaration appended to a certified translation by the translator, attesting that the translation is true and complete to the best of their knowledge. UKVI requires it to include the translator’s name, qualifications, contact details, and the date of certification.
The qualifications, professional memberships, and registration numbers of the translator who produced a certified translation. Often include CIOL/ITI/ATC membership, university degrees in translation, and registration with professional bodies. UKVI does not require specific credentials, but the certification statement must list whatever credentials the translator holds.
An electronic signature on a PDF. A certified translation for UKVI does not need a cryptographic digital signature — UKVI asks for a signed certification statement with the translator’s or company’s details. Visa upload portals can reject PDFs with broken or locked digital signatures, so certified translations are best delivered as plain, unlocked PDFs.
The practice of translating a finished translation back into the source language to check fidelity. Used in high-stakes legal and medical contexts but not required by UKVI. Adds cost and time without changing the certification status of the original translation.
The source language is the language of the original document; the target language is the language of the translation. UKVI requires the target language to be English (or Welsh for documents submitted in Wales).
Apostille, notarisation, and how foreign documents become valid in the UK.
A certificate issued under the 1961 Hague Convention that authenticates the origin of a public document for use in another signatory country. Apostilles authenticate the document itself, not its translation. UKVI does not require an apostille on translations, but documents sent overseas often need one.
The official confirmation that a signature, seal, or stamp on a UK document is genuine, so it can be used overseas. In the UK, legalisation is handled by the Foreign, Commonwealth & Development Office (FCDO). For Hague Convention countries the apostille process replaces full legalisation.
The international treaty that established the apostille as the standard authentication for public documents moving between member countries. Over 120 states are party to it, including the UK, US, Spain, France, Germany, India, and most EU and Latin American countries.
A qualified lawyer authorised to authenticate documents and signatures for use overseas. Notarisation does not certify the accuracy of a translation — it certifies the identity of the signer. In England and Wales, notaries are regulated by the Faculty Office of the Archbishop of Canterbury.
Visa routes administered by UKVI and the documentary requirements that apply to each.
