Brazilian Certidões

Two details cause more delays with Brazilian civil documents than anything else, and both are avoidable.

Inteiro Teor vs Breve Relato. A Brazilian certidão can be issued as a short-form summary (breve relato) or a full verbatim transcript (inteiro teor). Many US and foreign authorities require the full version, because the summary omits the registry history. We flag this when we review your document, before you pay for a translation you can't use.

Averbações - the Marginal Annotations. Brazilian birth and marriage certificates record later legal events in the margins: marriages, divorces, name changes, recognition of paternity, court orders. These are part of the certified document. We translate every averbação in full, with the date and registry action.

We also reproduce the registry references that identify the record, cartório, livro, folha, termo, exactly as they appear.

European and Brazilian Portuguese

Portuguese is not one single standard. European Portuguese, used in Portugal and much of Africa, and Brazilian Portuguese differ in vocabulary, grammar and style, and using the wrong variant makes a document read as foreign, or worse, causes confusion in official use. A certificate from Brazil and one from Portugal should be handled by a translator native to that variant.

PoliLingua assigns every project to a translator native to the correct variant. This page covers European Portuguese and general certified Portuguese translation, for Brazil-specific projects, see our dedicated Brazilian Portuguese translation services. Tell us the country of origin and destination in your quote request and we'll match the right translator.
