Yes. The Ministério das Relações Exteriores and Brazilian diplomatic missions route diplomatic correspondence, treaty drafts, and ministerial briefings through our Brasília diplomatic-translation pool. We work in formal Brasiliense Portuguese register and pair this with Hague Convention apostille at the receiving cartório when the document is destined for an embassy or foreign authority.

Why Day Translations
Calibrated to Brasília's diplomatic working day.
Since 2007 we’ve been the linguistic operations layer for the Itamaraty (Ministério das Relações Exteriores), the Supremo Tribunal Federal, the Câmara dos Deputados and Senado Federal, the Banco Central do Brasil, the Esplanada dos Ministérios, and the ~150 embassies and consular missions concentrated along the Avenida das Nações. Sworn (juramentado) Portuguese-Spanish-English translators for Mercosul filings; STF court-certified interpreters; embassy legalization runners working the Setor de Embaixadas.
That same Brasília operations layer runs on ISO 17100 quality and ISO 27001 security with HIPAA-aligned protocols and a SOC-2 readiness program — calibrated to the city’s actual working day. An Itamaraty diplomatic note in the morning, an STF certified-translation submission in the afternoon, and a Banco Central regulatory disclosure that evening all route through the same audit-ready vendor without you switching providers mid-week.
How we work
From file receipt to DOU-ready filing.
- 01
Diplomatic & federal intake
Files received over encrypted transfer; mapped against DOU (Diário Oficial da União) publication windows, STF court calendars, Itamaraty diplomatic-correspondence cycles, and Mercosul filing deadlines. Glossary aligned with Day's Brasília domain bank — diplomatic Portuguese register, federal procurement vocabulary, Mercosul trade lexicons, embassy legalization terminology.
- 02
Itamaraty & STF juramentado pairing
Sworn (tradutor juramentado) Portuguese-English-Spanish translators dispatched for STF and Itamaraty work; technical regulatory linguists assigned to Banco Central and Esplanada submissions; multilateral conference-grade simul teams routed to ministerial summits; Mandarin and Arabic linguists matched to Asian and Middle Eastern mission requirements.
- 03
DOU & embassy-legalization delivery
Signed Statement of Accuracy, certified Portuguese-Spanish-English document formatted for STF or Itamaraty submission, DOU-compliant federal-procurement pack for publication, and on-site interpreter dispatch when the diplomatic reception demands it. Hague apostille and embassy legalization handled in-house when the receiving authority requires it.

Why Brasília
Built for Brasília's deadline-bound workflows.
When DOU publication windows collide with STF court calendars and an embassy legalization needs to happen the same week — these are the operational realities the federal capital demands, and what we set up our work around.
