Official Spelling Standards
TL;DR
Portuguese has two official spelling standards, one used in Portugal and one in Brazil, even after a 1990 agreement tried to unify them. We match your translation to the correct variant so it reads naturally to the receiving authority.
- Brazil's Certidão de Nascimento and Portugal's Registo Civil certificates are genuinely different document formats, not just the same certificate
- Both Portugal and Brazil are long-standing Hague Apostille members
- Same $22.99 per page rate and 24 hour turnaround as every language on this hub
Why Portuguese Translation Is Different
Portuguese is officially one language, but Portugal and Brazil spell it differently, and a 1990 agreement meant to unify the two spelling systems didn't fully succeed. US Census Bureau data tracks Portuguese among the languages spoken across immigrant communities in the US, spanning all of its variants.
In 1990, Portugal, Brazil, and several other Portuguese-speaking countries signed an agreement meant to unify Portuguese spelling across the language. It took a long time to actually implement. Portugal made the new spelling mandatory in official documents starting in 2015, Brazil in 2016. This matters for your translation because a document translated into the wrong variant can read strangely to someone familiar with the other one, even though the underlying language is the same.

How Portuguese Spelling Varies by Country
Even with the 1990 agreement in place, spelling didn't fully unify. Roughly 1,000 words changed their spelling in Brazil under the reform, while more than 5,000 changed in Portugal, since the two countries were reconciling toward a common middle ground rather than one adopting the other's existing spelling outright. Real differences in spelling and civil-registry terminology remain between the two variants today.
We match your translation to the variant that fits your document's country of origin, whether that's Portugal, Brazil, or another Portuguese-speaking country like Cape Verde, Angola, or Mozambique. Angola and Mozambique generally follow closer to the European spelling standard, while remaining fellow signatories of the 1990 agreement.
Common Portuguese Documents We Translate
| Country | Common documents |
|---|---|
| Brazil | Certidão de Nascimento (birth certificate), Certidão de Casamento (marriage certificate) |
| Portugal | Registo Civil birth and marriage certificates |
| Cape Verde | Civil documents, one of the original signatories of the 1990 Orthographic Agreement |
Angola and Mozambique also use Portuguese as an official language, and we translate documents from both regularly, generally closer to the European spelling standard.

Portuguese Script and Spelling Conventions
Portuguese uses standard Latin script, with a few marks that don't appear in English.
- Nasal vowels are marked with a tilde, as in São or Não
- Cedillas appear under the letter c in words like ação
- Spelling conventions differ between the European and Brazilian variants even for the same word. We match the variant to your document's origin
Portuguese Document Authentication & Apostille Process
Both Portugal and Brazil are long-standing Hague Apostille members, so authentication for documents from either country is generally straightforward. It's the original document that gets apostilled, not the translation itself. Our Countries We Cover page has more detail if your document is from a different Portuguese-speaking country.
