Simultaneous Interpretation — Legal
The weight of words. Preserved in every language.
What is simultaneous interpretation for the Legal Sector?
Simultaneous interpretation for the legal sector is the real-time translation service for international arbitration (CAM-CCBC, ICC, ICSID), cross-border M&A legal due diligence, contract negotiations with foreign parties, and hearings with judges, arbitrators and international counsel — with specific legal vocabulary and unrestricted terminological rigor.
Why lingo for the Legal Sector
Binding terminological precision
"Estoppel" is not "impediment." "Warranty" is not "guarantee." lingo's legal glossary maintains functional equivalence between common law and civil law.
Professional privilege respected by design
Standard contract with a 5-year post-termination bilateral confidentiality clause. Audit trail with SHA-256 hash when needed.
Calibrated by the criticality of the legal act
Arbitration hearings and depositions require an experienced human interpreter, with more than 20 years of accumulated financial-legal specialization.

CAM-CCBC arbitration hearing with a foreign witness
8-hour session with a witness testifying in English, tribunal in Portuguese. Specialized human interpreter — no AI in acts that produce legal effects.
Cross-border M&A legal due diligence
Legal DD in parallel with financial DD. lingo interpreted full M&A cycles — Admix × Aon, CMA CGM × Santos Brasil.
ISDA Master Agreement negotiation
Negotiation session with a foreign counterparty. Terms like "cross-default" and "close-out netting" carry specific legal effects that admit no paraphrase.
Regulatory meeting with the DOJ or SEC
Meetings with American regulators require precision and record-keeping. lingo prepares a specific glossary with the team before every meeting.
Brazilian witness deposition via letters rogatory for a US proceeding
Discovery of a Brazilian witness in US civil litigation, with a specific protocol to preserve admissibility of the testimony before a foreign court.
Cross-border intellectual property licensing negotiation
Session between a Brazilian company and a European licensor covering royalties, territorial exclusivity clauses and patent milestones — technical IP terminology in English alongside parallel commercial negotiation.

Why international arbitration grew in Brazil over the last decade
The volume of international arbitrations involving Brazilian parties has grown steadily since the mid-2010s, as foreign private equity funds and international strategic buyers began requiring arbitration clauses (instead of Brazilian courts) as a standard condition in M&A and joint venture contracts. This changed the profile of the work lingo interprets: it's now common for the same dispute to go through CAM-CCBC (local seat, international rules) or ICC Paris, with witnesses and technical experts testifying in English or Spanish before a multilingual arbitral tribunal. lingo interprets these proceedings with the same rigor a judicial hearing would demand — the difference is that, in arbitration, the interpreter often has to navigate between the foreign counterparty's common law terminology and Brazil's civil law tradition within the same session, without either side noticing the transition. Tribunal secretaries increasingly expect a written record alongside the interpreted testimony, which is why lingo's audit-trail practice — verifiable transcripts with an integrity hash, never permanently stored audio — has become as relevant to arbitration counsel as the interpretation itself. Tribunals seated in Brazil under CAM-CCBC rules have also grown more comfortable admitting witnesses who testify partly in Portuguese and partly in English within the same hearing, which places additional demands on the interpreter to track register and legal nuance across both languages without flattening either one.

How to hire — quote in 60 seconds
Reach out via WhatsApp (+55 11 97534-6423) or the calculator at lingo.com.br/orcamento. Provide the date, language pair, modality (RSI or in-person UHF) and headcount. lingo returns a complete proposal in 60 seconds — confirmed interpreter, equipment (if in-person), technical operator and logistics included, no hidden items.
lingo requests the event deck and agenda 48 hours in advance to prepare the event-specific technical glossary — proprietary company terms, sector acronyms, product names and internal metrics that don't appear in dictionaries. For recurring mandates, the glossary accumulates session by session. After 12 months of monthly boards, the interpreter knows the company's internal vocabulary as well as any senior executive. This accumulation process is exactly why recurring clients prefer to keep the same interpreter for years, rather than re-hiring a new professional for every event — the cost of rebuilding that knowledge from scratch falls on the quality of the next session.
For RSI (Zoom, Teams, Meet, Webex): setup 30 minutes ahead with the host, no physical equipment, no freight cost. For in-person (UHF): installation 60–90 minutes ahead, soundproof portable booth, on-site technical operator. For hybrid: both modalities run in parallel. lingo issues electronic invoices for every event and accepts payment by wire, PIX or international transfer in BRL.
Documented portfolio with verifiable mandates
lingo operates exclusively in the premium corporate market for more than 20 years. There are no academic, government, religious or entertainment events in the portfolio. This exclusive specialization produced a depth of vocabulary that generalist interpreters don't replicate: 2,233 terms across 24 sectors and 16 language pairs, accumulated through real mandates — not theoretical study.
Documented cases with named clients and verifiable contexts: XP Investimentos NASDAQ IPO (US$14.9B, 2019), CMA CGM × Santos Brasil (R$6.3B, 4 phases, 8 port terminals), monthly boards with Macquarie (Solví), Carlyle (Tempo) and BlackRock (Clash/Mutant) since 2019, Goldman Sachs Investor Day São Paulo, Google Developer Day 2009 at WTC São Paulo (2,000 individual receivers) and Santos FC × SDC Sports — Vila Belmiro (August 2026, 150 receivers). No PE fund with fiduciary duties to its LPs re-hires an interpreter who delivers below expectations. Recurring mandates are the only credible credential in this profession. Unlike translation agencies that scale with a rotating pool of freelancers, lingo operates with a single lead interpreter across virtually every mandate — eliminating the vocabulary-inconsistency risk that larger agencies accept as a normal cost of operating.
How lingo prepares vocabulary for the Legal Sector
Terminological accuracy in the Legal Sector is built before the event, not during. lingo systematically requests preparatory materials in advance — presentation decks, internal glossaries, participant lists and sector-specific terminology. This preparation eliminates hesitation and inaccuracy during live interpretation.
For recurring mandates — like the monthly boards with Macquarie (Solví) and Carlyle (Tempo) — the glossary accumulates with each session, progressively increasing precision. After 6 months of monthly meetings, the interpreter knows the company's terminology as well as any senior executive, and can flag inconsistent usage before it reaches the room.
In-person vs. remote for the Legal Sector
For the Legal Sector events, the modality depends on the event's type and size. Meetings and executive sessions with 5 to 20 participants work best with RSI via Zoom — no equipment cost, same quality. Conferences, investor days and trade shows with 50+ participants require the in-person system with individual UHF receivers and a portable booth. Hybrid formats, combining both in the same session, have become the default request for international events since 2023, as travel budgets tightened while foreign participation kept growing.
lingo operates both modalities at the same level of excellence, and has held active remote mandates with Carlyle, Macquarie and BlackRock since 2019 — proving that RSI does not compromise quality in high-stakes corporate contexts.
What sets lingo apart in the Legal Sector
Brazil's simultaneous interpretation market has few professionals with a documented portfolio in high-stakes corporate contexts. Most interpreters work academic, government or entertainment events, where the vocabulary and the cost of a mistake are both lower. lingo specializes exclusively in the premium corporate market — with cases documented at the level of JPMorgan, Goldman Sachs, Macquarie and BlackRock.
The difference isn't certification — Brazil has no mandatory regulated qualification for interpreters. It's the clients: when Macquarie, Carlyle and BlackRock return month after month, the quality is self-evident. Recurring mandates are the only credible signal of consistency in this profession.
