What we do
Our services
What are translation services for litigation and international law?
Translation services for litigation and international law convert legal documents, evidence, and oral testimony between languages under certified quality control, so foreign-language material is admissible before English courts, tribunals, and international arbitral panels without procedural challenge.
Which legal documents require certified translation for litigation?
Legal documents requiring certified translation for litigation include contracts, witness statements, expert reports, disclosure exhibits, pleadings, court orders, corporate records, powers of attorney, and correspondence.
What are the admissibility rules for translated evidence in English courts?
Admissibility rules under CPR Practice Direction 32, paragraph 23 require that any exhibit not in English be accompanied by a translation, verified by a statement of truth, and filed with the witness statement.
What is the difference between certified, sworn, notarised, and apostilled translation?
Certified translation carries a translator’s signed accuracy statement; sworn translation is produced by a court-registered sworn translator in civil-law jurisdictions; notarised translation adds a notary’s identity verification; apostilled translation carries a Hague Convention certificate legalising the notary’s signature for foreign use.
How does translation work in international arbitration?
In international arbitration, translation is governed by the tribunal’s procedural order and the seat rules.
Which languages are covered for legal translation in London?
Legal translation London covers 200+ languages under ISO 17100 quality control, including the highest-demand pairs for UK disputes: Arabic, Russian, Mandarin, Cantonese, Korean, Japanese, French, German, Spanish, Portuguese, Italian, Polish, Turkish, Farsi, Ukrainian, and Hebrew.
Cross-border disputes place foreign-language contracts, witness accounts, and disclosure exhibits at the centre of the record. Certified legal translation for UK-seated litigation, cross-border disputes, and international arbitration under ISO 17100 quality control turns that material into court-ready evidence, and sits inside our broader Translation Services in London and the UK practice.
What are translation services for litigation and international law?
Translation services for litigation and international law convert legal documents, evidence, and oral testimony between languages under certified quality control, so foreign-language material is admissible before English courts, tribunals, and international arbitral panels without procedural challenge. The service anchors on ISO 17100:2015, the international standard specifying translator qualifications, mandatory revision by a second linguist, and documented project management. Every engagement is handled by qualified, experienced translators who understand the crucial need for accurate and faithful translations — precision errors in litigation documents carry procedural and strategic consequences that cannot be undone at the hearing stage.
Our translation and interpreting service has been trusted by 19 of the UK’s top 20 law firms and seven of the top ten law firms globally, a record that reflects the consistency and rigour our teams bring to every matter. Nine of our top ten clients have worked with us for at least five years, which demonstrates the depth of trust built through repeated, high-stakes instruction. That sustained relationship matters in litigation: counsel and their clerks need a partner who already understands their file-naming conventions, confidentiality requirements, and filing deadlines — not one learning those norms mid-matter.
- Quality standard: ISO 17100 certified, with two-linguist workflow (translation + revision).
- Language coverage: 200+ languages, including Arabic, Russian, Mandarin, French, German, Spanish, and Polish.
- Starting price: £30 per page.
- Turnaround: Same-day before 11:00 GMT for civil documents under 1,000 words; 24–48 hours for standard legal packs; milestone delivery for projects above 10,000 words.
- Certification options: Certified, sworn (via partner sworn translators abroad), notarised, and apostilled.
- Confidentiality: Matter-specific NDAs and an encrypted client portal protect every file from instruction to delivery.
Which four workflows sit inside a litigation translation engagement?
Litigation translation splits into four distinct workflows: disclosure review translation, evidential translation, court-filed certified bundles, and hearing interpretation. Each workflow carries different accuracy standards, deadline pressures, and admissibility requirements under English civil procedure and international arbitration rules. Disclosure review translation is gist-level for volume triage, escalating to full ISO 17100 human translation for priority documents. Evidential translation demands complete fidelity to source meaning, because any ambiguity in a translated contract clause or witness exhibit is exploited in cross-examination. Court-filed certified bundles must satisfy CPR Practice Direction 32, paragraph 23, which requires that any translation of a foreign-language exhibit be verified by a statement of truth — a requirement our certified output satisfies as standard. Hearing interpretation, whether consecutive or simultaneous, is delivered by sworn interpreters whose professional standing withstands challenge from opposing counsel.
| Workflow | Purpose | Accuracy standard | Typical output |
|---|---|---|---|
| Disclosure review translation | Filter foreign-language custodian data for relevance and privilege | Gist + priority full translation | Reviewer-ready summaries and tiered translations |
| Evidential translation | Prepare exhibits, contracts, and witness material for the record | Full human translation, two-linguist ISO 17100 | Certified English translation with accuracy statement |
| Court-filed certified bundles | File exhibits under CPR PD 32 paragraph 23 | Certified with statement of truth | Bundle-ready PDF with certificate and translator identity |
| Hearing interpretation | Live testimony at trial or arbitration hearings | Consecutive or simultaneous, sworn interpreters | On-site or remote interpretation; transcript optional |
Who instructs legal translation in a UK dispute?
Solicitors, barristers’ clerks, in-house counsel, litigation funders, and expert witnesses instruct legal translation in a UK dispute. Instructions arrive from magic-circle firms, boutique disputes practices, insurance panel counsel, and international arbitration teams seated in London. Each instructing party has a distinct set of requirements: solicitors need court-compliant certified output; barristers’ clerks need bundle-ready formatting; in-house counsel need confidentiality structures that satisfy their group legal policies; and litigation funders need reliable translated records to underwrite their risk assessment. Our teams are structured to serve all of these requirements simultaneously, with segregated linguist pools allocated per matter to prevent cross-contamination of confidential information.
- Solicitors preparing witness statements with foreign-language exhibits.
- Barristers’ clerks needing hearing bundles filed at the High Court of Justice.
- In-house counsel managing multi-jurisdiction contract disputes.
- Litigation funders reviewing foreign-language corporate records for due diligence.
- Expert witnesses producing reports referencing foreign statutes, filings, or scientific data.
Which legal documents require certified translation for litigation?
Legal documents requiring certified translation for litigation include contracts, witness statements, expert reports, disclosure exhibits, pleadings, court orders, corporate records, powers of attorney, and correspondence. Each foreign-language exhibit filed at court must be accompanied by a verified English translation.
| Document type | Typical use in dispute | Certification level |
|---|---|---|
| Contracts and commercial agreements | Breach, interpretation, governing-law arguments | Certified |
| Witness statements | CPR Part 32 evidence at trial | Certified with statement of truth |
| Expert reports | CPR Part 35 expert evidence | Certified |
| Disclosure exhibits | CPR Part 31 / Disclosure Pilot bundles | Certified or gist depending on tier |
| Pleadings and court orders | Foreign-court filings served on UK parties | Certified |
| Foreign judgments | Recognition and enforcement | Certified, often notarised or apostilled |
| Corporate records | Directors’ duties, corporate veil, group structure | Certified |
| Powers of attorney | Authority to act, settlement authority | Certified, often notarised |
How are contracts and commercial agreements translated for disputes?
Contracts and commercial agreements for disputes are translated clause-by-clause with defined terms preserved, governing-law citations retained, and a certificate of accuracy attached. Translators cross-reference dual-language originals to flag drafting ambiguities that become issues at trial.
- Defined terms rendered consistently against a matter-specific glossary.
- Governing-law and jurisdiction clauses translated with source-jurisdiction citation format retained.
- Discrepancies between language versions flagged in a translator’s note for counsel.
- Signature blocks, dates, and execution formalities transcribed verbatim.
How are witness statements and expert reports translated?
Witness statements and expert reports are translated with a statement of truth in both languages, first-person voice preserved, and technical terminology aligned to the CPR 35 expert framework. Translators do not alter substance, hedges, or qualifications made by the witness. Technical evidence relying on engineering, IT, or finance content is handled by linguists briefed against our Expert Technical Translation Services in London workflow.
How is disclosure and e-discovery material translated at scale?
Disclosure and e-discovery material is translated in tiered workflows: keyword-hit review in the source language, priority-document human translation, and gist translation of the long tail. Volumes above 10,000 words move to milestone delivery under ISO 17100.
- Foreign-language keyword search against custodian data in-language.
- Reviewer briefing with bilingual summaries of hits.
- Priority human translation of hot documents for evidential use.
- Gist translation of the long tail for relevance triage.
- Certified translation of documents selected for trial bundles.
How are pleadings, court orders, and judgments translated?
Pleadings, court orders, and judgments are translated with formal court formatting preserved, case citations retained in their original jurisdiction format, and party names rendered consistently. Translations of foreign judgments used for enforcement carry a certificate of accuracy for the receiving court.
What are the admissibility rules for translated evidence in English courts?
Admissibility rules under CPR Practice Direction 32, paragraph 23 require that any exhibit not in English be accompanied by a translation, verified by a statement of truth, and filed with the witness statement. Failure to comply risks the evidence being disallowed at trial.
- Identify every foreign-language exhibit annexed to a witness statement.
- Prepare a certified English translation for each exhibit.
- Attach a signed statement of truth naming the translator and confirming accuracy.
- File the translation with the witness statement, not separately.
- Serve the translated bundle on all parties within the CPR-mandated timetable.
What does CPR PD 32 paragraph 23 require?
CPR PD 32 paragraph 23 requires the party filing a witness statement exhibiting a non-English document to file a translation and confirm the translator’s identity. The translation is verified by a signed statement of truth. The certificate names the translator, states their qualifications, and confirms the translation is a true and accurate rendering of the source.
How does the Civil Evidence Act 1995 treat translated documents?
The Civil Evidence Act 1995 admits hearsay evidence subject to notice requirements, and translated documents are treated as secondary evidence of the original. Courts retain discretion to weigh a translation’s reliability when the certification standard is contested, which raises the practical stakes on translator credentials, ISO 17100 process, and audit trail.
What is the difference between certified, sworn, notarised, and apostilled translation?
Certified translation carries a translator’s signed accuracy statement; sworn translation is produced by a court-registered sworn translator in civil-law jurisdictions; notarised translation adds a notary’s identity verification; apostilled translation carries a Hague Convention certificate legalising the notary’s signature for foreign use.
| Type | Who signs | Where accepted | Typical use |
|---|---|---|---|
| Certified | Translator or agency | UK courts, tribunals, most common-law jurisdictions | Witness exhibits, contracts, pleadings for High Court filings |
| Sworn | Court-registered sworn translator | France, Spain, Germany, Italy, Poland, Brazil | Documents filed at civil-law courts abroad |
| Notarised | Notary public witnessing translator affidavit | Various government and immigration authorities | Documents requiring identity verification of the translator |
| Apostilled | Designated authority under the 1961 Hague Convention | 130 contracting states | Notarised documents travelling to a Hague member state |
See also our Online Certified Translation Services in the UK for remote instruction of the certified tier without in-person notary attendance.
When does a UK court accept a certified translation?
A UK court accepts a certified translation when it carries the translator’s or agency’s signed statement of accuracy, contact details, credentials, and date. No notarisation is required for filing at the High Court, County Court, or First-tier Tribunal unless a specific order says otherwise.
When is a sworn translation required for foreign proceedings?
A sworn translation is required for foreign proceedings when a civil-law jurisdiction mandates a court-registered sworn translator’s stamp on evidence, corporate records, or judgments filed at their courts. Civil-law jurisdictions requiring sworn translators include France, Spain, Italy, Germany, Poland, and Brazil. English common law does not use sworn translators; certified suffices at home.
When is notarisation or an apostille needed?
Notarisation is needed when the receiving authority requires a notary to verify the translator’s identity; an apostille is needed when the notarised document travels to a Hague Convention state. Non-Hague states require consular legalisation at the destination country’s embassy.
- Document origin in a Hague state, destination Hague state: notarise, then apostille.
- Document origin in a Hague state, destination non-Hague state: notarise, then consular legalisation at the destination embassy in London.
- Document origin in a non-Hague state: follow the origin country’s authentication chain, then UK consular legalisation.
- Domestic UK court filing only: certified translation alone; no notary or apostille required.
The Hague Convention of 5 October 1961 has 130 contracting parties and abolishes consular legalisation between them.
How does translation work in international arbitration?
In international arbitration, translation is governed by the tribunal’s procedural order and the seat rules. LCIA, ICC, SIAC, and UNCITRAL rules leave language choice to the parties or tribunal, and translation costs are recoverable as legal costs in the final award.
How do LCIA, ICC, SIAC, and UNCITRAL rules treat language?
LCIA Article 17, ICC Article 20, SIAC Rule 22, and UNCITRAL Article 19 give the tribunal discretion to fix the arbitration language and require translations of exhibits in another language. Practice varies from English-only bundles to fully bilingual filings.
| Rules | Language provision | Practical effect |
|---|---|---|
| LCIA | Article 17 | Tribunal fixes language and orders translations of non-language exhibits |
| ICC | Article 20 | Arbitral tribunal determines language of the arbitration absent party agreement |
| SIAC | Rule 22 | Tribunal determines language and translation duties |
| UNCITRAL | Article 19 | Tribunal determines language and may order translations of documentary evidence |
Are translation costs recoverable in an arbitral award?
Translation costs are recoverable in an arbitral award as part of the costs of the arbitration under LCIA Article 28, ICC Article 38, and UNCITRAL Article 40. Successful parties recover reasonable translation invoices backed by ISO 17100 certificates and page-count evidence. Enforcement of foreign arbitral awards under the New York Convention 1958 requires a certified translation of the award for the enforcing court.
Languages
Which languages are covered for legal translation in London?
Legal translation in London covers more than 200 languages under ISO 17100 quality control, including the highest-demand language pairs arising from UK commercial disputes, international arbitration, family law, immigration appeals, and criminal proceedings. Every language pair is served by translators who are not only fluent but who carry subject-matter experience in legal, financial, or regulatory documentation — because linguistic fluency alone is insufficient when the source document is a share purchase agreement, a foreign court order, or a civil-law notarial deed.
- Middle East and North Africa: Arabic, Farsi, Hebrew, Turkish, Dari, Pashto.
- CIS and Eastern Europe: Russian, Ukrainian, Polish, Romanian, Bulgarian, Czech, Slovak, Serbian, Croatian.
- East Asia: Mandarin, Cantonese, Korean, Japanese, Vietnamese, Thai, Indonesian.
- Western Europe: French, German, Spanish, Portuguese, Italian, Dutch, Greek, Swedish, Danish, Norwegian.
- South Asia: Hindi, Urdu, Punjabi, Bengali, Gujarati, Tamil, Sinhala.
- Africa: Swahili, Amharic, Tigrinya, Somali, Yoruba, Igbo.

What is included in a certified legal translation quote?
A certified legal translation quote includes source-word or page count, target language, certification wording, notarisation or apostille fees where required, turnaround time, and delivery format. Rush surcharges apply only for out-of-hours delivery outside the same-day 11:00 GMT window.
- Source word count or standardised 250-word pages.
- Target language and any variant (e.g., Simplified vs Traditional Chinese, European vs Brazilian Portuguese).
- Certification wording appropriate to the receiving court or tribunal.
- Notary or apostille fees itemised separately.
- Delivery format: PDF, DOCX, hard-copy courier, or secure client portal upload.
How fast can urgent litigation translations be delivered?
Urgent litigation translations are delivered same-day for civil documents under 1,000 words placed before 11:00 GMT, within 24 to 48 hours for legal and document packs, and on agreed milestones for projects above 10,000 words — all produced under ISO 17100 two-linguist quality control so that speed never compromises the accuracy standard required for court admissibility.
Deadline management is one of the most operationally critical aspects of litigation support. Court filing deadlines, arbitration timetable orders, and without-notice application windows are fixed and non-negotiable. Our dispatch model is structured so that instructions received before 11:00 GMT in London enter the same-day workflow immediately, with a translator allocated within minutes and a project manager assigned to monitor progress through to delivery. For larger matters — multi-party disclosure exercises or hearing bundles running to tens of thousands of words — milestone delivery schedules are agreed at instruction, giving the legal team a reliable production timetable they can present to the court or tribunal.
| Volume | Turnaround | Cut-off / note |
|---|---|---|
| Under 1,000 words (civil documents) | Same day | Instruction before 11:00 GMT, London |
| 1,000–5,000 words | 24–48 hours | Working-day placement |
| 5,000–10,000 words | 3–5 working days | Working-day placement |
| 10,000+ words | Milestone delivery | Scoped and confirmed at instruction |
Every delivery includes the certified accuracy statement required for court filing, so the instructing solicitor receives a bundle-ready document rather than raw translated text that still requires post-processing. Where a matter requires both translation and simultaneous telephone or face-to-face interpretation support — for example, a client conference or an urgent without-notice hearing — both services can be instructed through a single point of contact, eliminating coordination delays when time is shortest.
About
How is confidentiality and legal privilege protected?
Confidentiality and legal privilege are protected through NDA-first onboarding, segregated linguist pools per matter, encrypted file transfer, UK-hosted storage, and a strict no-machine-translation policy on litigation files. Translators sign matter-specific confidentiality undertakings before receiving any document.
- NDA-first onboarding: signed before source files leave counsel’s custody.
- Segregated linguist pools: matter-specific teams, no cross-instruction sharing.
- Encrypted transfer: TLS-secured portal, no email attachments for privileged material.
- UK-hosted storage: data resident in the UK for the life of the matter.
- No-MT policy: machine translation prohibited for any litigation matter file.
How is conflict of interest checked before instruction?
Conflict of interest is checked before instruction by cross-referencing party names, counsel firms, and subject matter against active and past matter files. Where a conflict exists, the instruction is declined or ring-fenced with an alternative linguist team and separate project management.
How do you instruct a translation team for a live matter?
To instruct a translation team for a live matter, send the source files with the target language, deadline, certification level, and any court or tribunal filing date; a fixed quote is issued within one working hour under a matter-specific NDA. Instructions placed before 11:00 GMT enter the same-day delivery workflow automatically, with a dedicated project manager allocated from the moment of instruction.
The instruction process is designed to impose no friction on busy litigation teams. Solicitors and barristers’ clerks working on live matters cannot afford the delays that come from lengthy onboarding processes, back-and-forth on pricing, or uncertainty about who is handling their files. Our model resolves all three concerns: files are transmitted through an encrypted client portal, pricing is fixed and confirmed within the hour, and every matter is allocated to a segregated linguist team operating under a matter-specific confidentiality agreement. Nine of our top ten clients have returned to us repeatedly for at least five years, which reflects the operational reliability that litigation practices require from a translation partner.
- Send source files via the encrypted client portal or secure link — all formats accepted including PDF, Word, and scanned exhibits.
- State the target language and any regional variant required by the receiving court or jurisdiction.
- Confirm the certification level: certified (for UK courts), sworn (for civil-law jurisdictions), notarised, or apostilled under the 1961 Hague Convention.
- Specify the deadline and any hard court or tribunal filing date so the team plans quality-review cycles within the available window.
- Sign the matter-specific NDA returned with the fixed quote — returned within one working hour of instruction.
- Approve the quote to trigger immediate allocation to the dedicated, segregated linguist team for this matter.
- Receive delivery in the agreed format — bundle-ready PDF with the certificate of accuracy and translator identity attached as standard.
Where a matter requires sworn translation for use in a civil-law jurisdiction such as France, Germany, Spain, Italy, or Poland, or where documents must proceed to notarisation and apostille, those requirements are captured at the instruction stage and coordinated as a single managed workflow. The instructing solicitor receives one set of compliant documents rather than managing multiple separate suppliers across jurisdictions.
