What is professional legal document translation with certification?
Professional legal document translation with certification is the rendering of a legal document into another language accompanied by a signed statement of accuracy from a qualified translator or ISO 17100 agency, accepted by UK courts, the Home Office, Companies House, and overseas authorities as an official equivalent of the source.
How does certified translation differ from sworn, notarised, and apostilled translation?
Certified, sworn, notarised, and apostilled translations sit on a four-tier acceptance ladder: certified carries a translator’s statement of accuracy (UK standard), sworn is signed by a court-registered translator in civil-law countries, notarised adds a notary public verifying identity, and apostilled adds FCDO authentication under the 1961 Hague Convention.
Which UK authorities accept certified legal translations?
UK authorities accepting certified legal translations include the Home Office for visa and settlement applications, HM Courts and Tribunals Service for foreign-language evidence, Companies House for foreign company filings, the General Register Office for civil records, and UK ENIC for academic credentials.
Which legal document types do we translate?
We translate 12 core legal document types with certification: commercial contracts, court judgments, affidavits, statutory declarations, powers of attorney, wills and probate documents, patents, articles of association, birth certificates, marriage certificates, divorce decrees, and police clearance certificates.
How much does certified legal document translation cost in the UK?
Certified legal document translation in the UK starts from £30 per page under ISO 17100 quality control, with pricing driven by source word count, language pair, document complexity, and whether notarisation or apostille layers are added.
How fast can a certified legal translation be delivered?
Certified legal translations are delivered same-day for civil documents under 1,000 words placed London before 11:00 GMT, within 24 to 48 hours for legal and academic packs, and on agreed milestones for projects above 10,000 words, all under ISO 17100 quality control.
Complete guide
Everything about certified legal document translation in the UK
UK-facing legal document translation demands more than linguistic accuracy: it demands a certification statement mapped to the correct receiving authority, produced under ISO 17100 quality control, and issued in a form the Home Office, HMCTS, Companies House, and overseas ministries will actually accept.
What is professional legal document translation with certification?
Professional legal document translation with certification is the rendering of a legal document into another language accompanied by a signed statement of accuracy from a qualified translator or ISO 17100 agency, accepted by UK courts, the Home Office, Companies House, and overseas authorities as an official equivalent of the source.
The service combines three components:
- Translation — performed by a legal-specialist linguist qualified in the source and target languages.
- Revision — performed by a second qualified linguist under ISO 17100.
- Certification — a signed statement on agency letterhead confirming the translation is true and complete against the original.
What does the certification statement contain?
A UK certified translation carries seven mandatory elements: translator or agency name, credentials, signature, date, contact address, source and target languages, and an explicit declaration that the translation is a true and accurate rendering of the original.
| # | Mandatory element | Purpose |
|---|---|---|
| 1 | Translator or agency name | Identifies the certifying party |
| 2 | Credentials (ITI, CIOL, ISO 17100) | Evidences competence |
| 3 | Signature | Legal attestation |
| 4 | Date of certification | Anchors validity in time |
| 5 | Contact address | Enables authority follow-up |
| 6 | Source and target languages | Fixes the linguistic scope |
| 7 | Statement of accuracy and completeness | Declares fidelity to the original |

Who is qualified to certify a legal translation in the UK?
In the UK a certified translation is produced by a professional translator holding a recognised qualification, working through an ISO 17100 agency, or a member of the ITI or CIOL; a solicitor or notary is only required when the receiving body specifies notarisation. The Chartered Institute of Linguists (CIOL) and the Institute of Translation and Interpreting (ITI) are the two professional bodies UK authorities recognise for certification signatures.
How does certified translation differ from sworn, notarised, and apostilled translation?
Certified, sworn, notarised, and apostilled translations sit on a four-tier acceptance ladder: certified carries a translator’s statement of accuracy (UK standard), sworn is signed by a court-registered translator in civil-law countries, notarised adds a notary public verifying identity, and apostilled adds FCDO authentication under the 1961 Hague Convention.
| Tier | What it adds | Where it applies | Typical use |
|---|---|---|---|
| Certified | Translator’s signed statement of accuracy | UK — Home Office, HMCTS, Companies House, GRO, UK ENIC | Visa, court evidence, filings |
| Sworn | Court-registered translator’s stamp | France, Spain, Germany, Italy, Poland | Civil-law jurisdictions |
| Notarised | Notary public verifies translator identity | UAE, China, some US states, embassies | Overseas academic and corporate use |
| Apostilled | FCDO authenticates the notary’s signature | 1961 Hague Convention states | Cross-border legalisation |
When is a sworn translation required instead of certified?
A sworn translation is required when the receiving authority sits in a civil-law jurisdiction such as France, Spain, Germany, Italy, or Poland, where only court-registered sworn translators (traducteur assermenté, traductor jurado, vereidigter Übersetzer) can produce legally admissible translations. Sworn translator status is not a UK legal category; UK certified translations are re-routed through partner sworn translators when the destination country demands it.
When is a notarised translation required?
A notarised translation is required when a foreign authority, university, or embassy demands independent verification of the translator’s identity by a notary public, common for documents destined for the UAE, China, and some US states. The notary verifies the translator’s identity and witnesses the signature — the notary does not certify the accuracy of the translation itself. Notarisation carries a separate fee on top of the certified translation.
When is an apostille required on a translated document?
An apostille is required when a notarised translation crosses borders between the UK and another Hague Convention state; the FCDO Legalisation Office in Milton Keynes issues the apostille that authenticates the notary’s signature. Under the 1961 Hague Apostille Convention the apostille replaces consular legalisation, so once affixed the document is accepted directly by the destination state without further embassy stamps.
Which UK authorities accept certified legal translations?
UK authorities accepting certified legal translations include the Home Office, HMCTS, Companies House, the General Register Office, and UK ENIC, each with its own document-to-authority routing. The table below maps the most frequently translated documents to the receiving body.
| Document | Receiving authority | Certification tier required |
|---|---|---|
| Birth certificate | GRO / Home Office | Certified |
| Marriage certificate | GRO / Home Office | Certified |
| Divorce decree | HMCTS / Home Office | Certified |
| Commercial contract | HMCTS (if disputed) | Certified |
| Company filings / articles | Companies House | Certified |
| Academic transcript | UK ENIC / UCAS | Certified |
| Power of attorney (outbound EU) | Foreign notary / court | Notarised + Apostilled |
| Police clearance certificate | Home Office | Certified |
How does the Home Office assess a certified translation?
The Home Office accepts a certified translation when it carries the translator’s full name, credentials, signature, date, contact details, and a statement confirming accuracy and completeness against the original document. Visa, settlement, and citizenship caseworkers verify the seven mandatory elements against the visa application guidance; missing any one triggers a request for further information and delays the case.
What do UK courts require for foreign-language evidence?
HMCTS requires a certified translation of any foreign-language evidence submitted in civil, family, or criminal proceedings, with the translator prepared to attend as an expert witness if the translation is challenged. Under the Civil Procedure Rules and Criminal Procedure Rules, any exhibit not in English must be filed alongside a certified English translation, and the translator is required to swear an affidavit.
Which legal document types do we translate?
We translate 12 core legal document types with certification: commercial contracts, court judgments, affidavits, statutory declarations, powers of attorney, wills and probate documents, patents, articles of association, birth certificates, marriage certificates, divorce decrees, and police clearance certificates.
- Commercial contracts — sale, distribution, employment, licensing.
- Court judgments — civil, family, commercial rulings.
- Affidavits and statutory declarations — sworn statements for litigation and immigration.
- Powers of attorney — general, specific, enduring.
- Wills and probate — testaments, grants of representation, inheritance filings.
- Patents and IP filings — routed through our Expert Technical Translation Services in London for technical accuracy.
- Articles of association — for Companies House and foreign registries.
- Civil status certificates — birth, marriage, divorce, death.
- Police clearance certificates — DBS and foreign equivalents.
How are contracts and commercial agreements handled?
Contracts and commercial agreements are translated by legal-specialist linguists under ISO 17100 two-linguist review, preserving defined-term consistency, clause numbering, and jurisdictional terminology across English and the target language. Complex legal terminology in contracts, patents, and court documents drives higher per-page rates because it demands specialised expertise, terminology research, and multi-stage quality control.
How are civil status documents handled?
Civil status documents such as birth, marriage, and divorce certificates are translated and certified same-day for pages under 1,000 words placed before 11:00 GMT, formatted to mirror the source layout for Home Office and GRO acceptance. Stamps, seals, and signatures on the source are described in brackets — [round seal, blue ink, GRO Southport] — so caseworkers match the certified translation against the original at a glance.

How fast can a certified legal translation be delivered?
Certified legal translations are delivered same-day for civil documents under 1,000 words placed in London before 11:00 GMT, within 24 to 48 hours for legal and academic packs, and on agreed milestones for projects above 10,000 words, all under ISO 17100 quality control. Every job passes through a two-stage process — translation by a CIOL- or ITI-qualified linguist followed by independent revision — so speed never comes at the expense of the accuracy standard that UK courts and the Home Office require. For urgent immigration matters, a same-day turnaround is available on most civil-status documents, including birth certificates, marriage certificates, and police clearance letters, provided the order is placed before the 11:00 GMT cut-off. Larger litigation bundles and corporate packs are scheduled with a dedicated project manager who issues milestone updates so that solicitors and in-house counsel always know exactly where their documents stand.
| Volume | Document type | Turnaround SLA |
|---|---|---|
| Under 1,000 words | Birth, marriage, divorce, police certificates | Same-day (order before 11:00 GMT) |
| 1,000–5,000 words | Contracts, judgments, statutory declarations | 24–48 hours |
| 5,000–10,000 words | Litigation bundles, corporate packs | 3–5 working days |
| Above 10,000 words | Discovery, patent portfolios, M&A | Milestone delivery, agreed schedule |
Pricing starts from £30 per page under ISO 17100, and a fixed quote is confirmed within 60 minutes during business hours. Rush fees are transparent and agreed upfront — there are no hidden charges added after delivery.
About
How is quality and confidentiality controlled under ISO 17100?
Quality and confidentiality are controlled through ISO 17100 two-linguist workflow, translator credential checks, terminology management, GDPR-aligned handling, NDA coverage on request, and encrypted file delivery, with every certified file traceable to the assigned linguists and reviser. The same controls govern our wider Professional Translation Services in the UK.
- Two-linguist workflow — every translation revised by a second qualified linguist.
- Credential verification — degrees, ITI/CIOL membership, and experience checked before assignment.
- Terminology management — client-specific glossaries preserved across projects.
- GDPR handling — files stored on UK/EU servers, deleted after project close on request.
- NDA coverage — mutual NDA issued on request before file upload.
- Encrypted delivery — TLS in transit, AES-256 at rest.
What does ISO 17100 require from translators?
ISO 17100 requires each translator to hold a recognised translation degree, an equivalent language qualification plus two years’ full-time experience, or five years’ full-time professional translation experience, and every project to be revised by a second linguist. The standard also specifies project management, resource management, and traceability of every file back to the linguists who produced it.
In which languages do we certify legal translations?
We certify legal translations across 200+ language pairs, covering every major language family and a wide range of rare and less-resourced languages. Whether the document originates from a European civil registry, a Middle Eastern court, or an East Asian corporate authority, we hold CIOL- and ITI-qualified translators for that language combination who are specifically experienced in legal terminology and the formatting conventions expected by UK receiving authorities. Our network has been built over more than 15 years and has been applied to over 300,000 documents, which means that even lower-volume languages such as Tigrinya, Sinhala, or Igbo are served by verified specialists rather than generalist linguists.
- European — French, German, Spanish, Italian, Portuguese, Dutch, Polish, Ukrainian, Romanian, Bulgarian, Greek, Czech.
- Middle Eastern — Arabic (MSA and dialects), Farsi, Hebrew, Turkish, Kurdish.
- East Asian — Mandarin, Cantonese, Japanese, Korean — the Korean pair is delivered through our Korean Translation Services London.
- South Asian — Hindi, Urdu, Bengali, Tamil, Punjabi, Gujarati, Sinhala.
- African — Somali, Swahili, Amharic, Tigrinya, Yoruba, Igbo.
Every certified translation, regardless of language pair, carries the same core certification statement: the translator’s or agency’s name, signature, date, contact details, a statement of accuracy, and the source and target languages — the precise elements that the Home Office, HMCTS, and Companies House require for acceptance. Court video and hearing recordings requiring transcription and translation are handled through our Subtitle Translation Services in London and issued with a matching certification statement for HMCTS submission.
How do you order a certified legal translation in London?
To order a certified legal translation in London, upload a scan or photograph of each document, confirm the target language and receiving authority, approve the fixed quote, and receive the signed certified PDF by email with hard copies posted on request. The process is designed to be straightforward whether you are a private individual preparing a visa application or a solicitor assembling a litigation bundle. Our team is accepted by UKVI, the Home Office, HM Passport Office, HMCTS, Companies House, and a wide range of government bodies, so you can name the exact authority at the point of ordering and we will ensure the certification statement meets that body’s specific requirements.
- Upload a scan or clear photograph of every page, including stamps and reverse sides.
- Confirm the target language and the receiving authority (Home Office, HMCTS, Companies House, GRO, UK ENIC, or overseas).
- Approve the fixed quote and SLA within 60 minutes during business hours.
- Receive the signed certified PDF by email; hard copies are dispatched by tracked post on request.
- Add notarisation or apostille layers when the destination country requires them.
Original documents do not need to be posted to us — a clear scan or photograph is sufficient for the vast majority of legal and official documents. If the receiving authority specifically demands a wet-ink hard copy, we dispatch by tracked and signed-for post. For documents that must also be notarised or authenticated with an apostille for use overseas, those additional layers are arranged as part of the same order, keeping the process under a single point of contact.
