Two Portuguese-speaking worlds, one certified translation desk
Portuguese arrives on our desks from two registry traditions: Brazil, where a cartório issues certidões and stamps recognitions on nearly everything, and Portugal, where the conservatória keeps assentos in its own format and phrasing. EKO 4 National Translation Service translates both, every working day — complete and word for word, seals and recognition stamps included, with a signed accuracy affidavit on official letterhead and our wet stamp, all backed by a 100% acceptance guarantee.
Brazilian paperwork carries details that decide cases. A certidão exists as inteiro teor (the full transcript) or breve relato (the summary), and the receiving authority often insists on one of them; the margins hold averbações, the annotations where divorces, name changes and corrections are recorded. We translate the annotations as faithfully as the main entry, and tell you free of charge if your receiver typically wants the other form. Serving all 50 states since 1991 — express 24-hour delivery available.

Why EKO 4 for this language
Inteiro teor or breve relato
Both forms of a Brazilian certidão cross our desks daily. We translate the one in your hands — and flag it early, at no cost, when your receiving authority usually demands the full transcript instead.
Margins read, not skimmed
Averbações carry the legal history of a record — divorces, name changes, corrections. Every annotation and the registrar stamps around it are translated word for word, because that is where officers look first.
Certification USCIS recognizes
A signed accuracy affidavit on official letterhead, wet-stamped — the complete 8 CFR 103.2(b)(3) package, standing behind our 100% acceptance guarantee.
Need it official? One order covers the whole chain
Certified translation, notarization and apostille — handled in-house, in a single online order, wherever in the country you are.
Certified translation
Word-for-word translation with a signed accuracy affidavit, official letterhead and wet stamp — accepted by USCIS, courts and authorities nationwide.
Notarization
A licensed notary notarizes your translation 100% online — no office visit, ready as fast as the next business day.
Apostille
We obtain the apostille from the correct competent authority — the issuing state’s Secretary of State, or the U.S. Department of State for federal documents — end to end.
Portuguese translation — questions & answers

EKO 4 National Translation Service delivers professional, human translation
in up to 72 languages — coast to coast
Every certified translation at EKO 4 is produced by a vetted human linguist — educated, widely experienced and genuinely at home in both of their languages. That is what allows us to stand behind a 100% accuracy guarantee across more than three decades of work.
From our first project in 1991 to the 50,000+ clients we serve today, the formula has never changed: careful translators, disciplined proofreading and honest service. It is why a first order so often becomes a working relationship that lasts for years.
EUROPEAN
ASIAN, AFRICAN, MIDDLE EASTERN
No translation leaves our hands on a single pass. Before any linguist joins EKO 4 they are recruited, vetted, interviewed and examined; once on a project, their work moves through editors and project managers who proofread it again before it ever reaches you. That layered process is the machinery behind our 100% accuracy guarantee.
Most of our 500+ translators and editors have spent years inside international, multi-cultural projects, so the finished document does not merely say the right words — it speaks to the audience, authority or market it was written for.
Professionalism, precision and fair pricing, backed by a 100% quality guarantee. Wherever in the country you are, EKO 4 speaks your language — explore all of them on our languages page.
