What is an affidavit translation?
An affidavit translation is the certified rendering of a sworn written statement from one language into another, accompanied by a signed statement of truth from the translator, so the translated affidavit can be used as evidence in UK courts, USCIS filings and overseas legal proceedings.
When is an affidavit translation required?
An affidavit translation is required whenever a sworn statement is submitted to a court, government body or university in a language different from the one in which it was written, including UK court proceedings, USCIS immigration files, marriage certificates for cross-border use, and Hague Convention apostille legalisation.
What is the difference between certified, sworn and notarised affidavit translations?
A certified translation is signed by the translator with a statement of truth; a sworn translation is signed before a court-authorised sworn translator (common in EU jurisdictions); a notarised translation is a certified translation whose translator signature is witnessed by a notary public; an apostilled translation adds FCDO legalisation for Hague Convention use.
What information is included in a certified affidavit translation?
A certified affidavit translation includes the full translated statement, the translator’s affidavit of translation, the translator’s name, qualifications, signature and date, the source and target languages, a statement of truth, page count, and the agency’s ISO 17100 certification stamp.
What are the specific formatting and seal requirements for an affidavit translation?
A UK affidavit translation must mirror the source document’s formatting, carry the ISO 17100 agency stamp on every page, be signed by the translator on the affidavit of translation page, and be bound with the source document so the receiving authority can verify the translation is complete.
How much does a certified affidavit translation cost in the UK?
A certified affidavit translation in the UK costs from £30 per page including VAT, with additional fees for notarisation (typically £30–£75 per signature), apostille legalisation from the FCDO (£30 per document), and a 25–50% surcharge for same-day rush turnaround.

How it works
How does the affidavit translation process work?
The affidavit translation process follows five steps: send the source document for a quote, a certified translator produces the translation, an editor and proofreader run the ISO 17100 TEP workflow, the translator signs the affidavit of translation, and the bundle is delivered by email with notarisation or apostille on request.

Complete guide
Everything you need to know
Certified translation of sworn statements for UK courts, USCIS, UKVI and overseas legal proceedings requires a professional translator, a signed statement of truth and — for some receiving authorities — notarisation or an apostille from the FCDO.
When is an affidavit translation required?
An affidavit translation is required whenever a sworn statement is submitted to a court, government body or university in a language different from the one in which it was written, including UK court proceedings, USCIS immigration files, marriage certificates for cross-border use and Hague Convention apostille legalisation. Documents must be translated and certified before filing; an uncertified translation is refused.
Do I need an affidavit translation for UK court proceedings?
You need an affidavit translation for UK court proceedings whenever a sworn statement in a foreign language is filed as evidence, because HMCTS requires all written statements to be in English and signed by the translator with a statement of truth. Our Legal Translation Services handle translations of legal documents filed under the Civil Procedure Rules, including affidavits, witness statements and exhibits.
Do I need an affidavit of translation for USCIS?
USCIS requires a certified translator’s affidavit of translation for every non-English document in an immigration file — including marriage certificates, birth certificates and police records — signed by the translator and attesting the translation is complete and accurate. U.S. Department of Justice rules make English translation mandatory for immigration court filings. Our Immigration Translation Services deliver USCIS-ready bundles with the translator’s affidavit attached.
Do I need an affidavit translation of a marriage certificate?
You need an affidavit translation of a marriage certificate when it is submitted to a UK court, the Home Office, USCIS or a university, because the receiving authority accepts marriage certificates only when translated and certified by a professional translator. Order through our Marriage Certificate Translation service for USCIS, UKVI and HMCTS acceptance.
When is an apostille or Hague Convention legalisation also required?
An apostille under the Hague Convention is also required when the translated affidavit will be used in a foreign signatory state, in which case the FCDO legalises the notary’s or solicitor’s signature after the translation is complete. The Hague Convention covers 126 signatory states that accept an apostille in place of consular legalisation. Order the full chain via our Apostille Translation Services.
What is the difference between certified, sworn and notarised affidavit translations?
A certified translation is signed by the translator with a statement of truth; a sworn translation is signed before a court-authorised sworn translator (common in EU jurisdictions); a notarised translation is a certified translation whose translator signature is witnessed by a notary public; an apostilled translation adds FCDO legalisation for Hague Convention use.
| Type | Who certifies | Typical receiving authority | Added cost |
|---|---|---|---|
| Certified | Professional translator, statement of truth on ISO 17100 letterhead | HMCTS, UKVI, Home Office, USCIS, UK universities | From £30 per page |
| Sworn Translation Services | Court-authorised sworn translator | EU civil-law courts (Spain, France, Germany, Italy) | Quoted per document |
| Notarised Translation Services | Notary public witnesses translator signature | Overseas courts, foreign consulates | £30–£75 per signature |
| Apostilled | FCDO legalises notary/solicitor signature | Hague Convention states (126 signatories) | £30 per document + FCDO fee |
Which affidavit translation type does your receiving authority need?
UK courts and UKVI accept a certified affidavit translation with a signed statement of truth; overseas courts often require sworn or notarised translations; Hague Convention states additionally require an apostille from the FCDO. Confirm the requirement with the receiving authority before the translation process begins, or send us the request letter and we route the file to the correct certification tier.
Can a solicitor certify a translation in the UK?
A solicitor can witness the translator swearing the affidavit of translation and can notarise the translator’s signature, but the translation itself must still be produced and signed by a professional translator qualified in the relevant language pair. A solicitor’s role is to administer the oath, not to translate.
Can I translate my own affidavit and submit it?
You cannot translate your own affidavit and submit it, because UK courts, USCIS and UKVI require the translation to be signed by an independent professional translator who swears the translation is a true and accurate representation of the source document. The Government of Canada’s IRCC applies the same rule and refuses translations by the applicant or family members — the UK, US and Canadian standard is consistent on this point.

How it works
Will my certified affidavit translation be accepted by courts and official bodies?
A certified affidavit translation produced by an ISO 17100 certified UK agency is accepted by UK courts (HMCTS), UKVI, the Home Office, USCIS, universities and overseas authorities, because it is signed by a professional translator with a statement of truth and can be notarised or apostilled when the receiving authority requires it.
Are your translations accepted by everyone?
Our translations are accepted by every UK court, UKVI, the Home Office, USCIS, the Hague Convention apostille chain, and the vast majority of universities and provincial or territorial organizations worldwide, and we guarantee acceptance or reissue the translation free of charge. Acceptance rules follow ATC (Association of Translation Companies) and EUATC standards.
Which receiving authorities have specific affidavit translation requirements?
UKVI and the Home Office require the translator’s contact details on every page; USCIS requires the translator’s affidavit of translation attached; the FCDO requires a solicitor’s or notary’s signature before apostille. Common receiving-authority translation requirements:
- HMCTS / UK courts — statement of truth, translator signature, English throughout.
- UKVI / Home Office — translator name, signature, date, contact details on every page.
- USCIS — translator’s affidavit of translation attached to every non-English document.
- FCDO apostille — solicitor or notary signature before legalisation.
- UK universities — certified translation on agency letterhead with ISO 17100 stamp.
