What's at stake

In legal work, translation isn't a detail — it's the risk

An ambiguous term in an arbitration clause. A literal rendering that changes the meaning of a contractual obligation. An interpreter who hesitates during a deposition and compromises the testimony. In your world, these aren't rework — they're lawsuits, losses and lost credibility.

My job is to make sure language is the one variable you don't have to fear: meaning, tone and intent preserved, with precise legal terminology on both sides of the table.

Frequently asked

Frequently asked questions — legal & arbitration

Do I need a sworn (certified) translation?

Official documents for court use may require a sworn translation, produced by a public sworn translator. For contracts, legal opinions, arbitration submissions and communication between parties, specialized technical translation meets the highest standards. Tell me about your case and I'll point you to the right path.

Do you handle remote international arbitration?

Yes. Remote simultaneous interpreting (RSI) via professional platforms such as KUDO and Interprefy, with the same precision as on-site work and no travel cost — ideal for hearings and meetings with parties in different countries.

How is confidentiality handled in sensitive cases?

Absolute confidentiality. I work regularly with sensitive documents and negotiations and sign an NDA whenever required.

What's the difference between simultaneous and consecutive interpreting in hearings?

In simultaneous interpreting, the rendering happens in real time — ideal for long hearings and conferences. In consecutive interpreting, the interpreter speaks during pauses — often preferred in depositions and examinations, where each answer must be recorded precisely.

Which languages are available?

Interpreting and translation between Portuguese, English, Spanish and French. Translation also in Italian, German and Mandarin.
