| PT-PT and PT-BR confused | Vocabulary, grammar and register differ (comboio/trem, estar a fazer/estar fazendo). The wrong variety reads as foreign to the target audience and, for an authority, misses the brief. | We fix the target variety before the project and hold it consistent through translation memory and a style guide. |
| Address wrong (você / tu / o senhor) | In Brazil você is neutral; in Portugal it can sound distant, where tu or o senhor is used. The wrong form of address strikes the wrong tone in a contract or letter. | We set the register and address to the target variety and the document type deliberately. |
| Nasal vowels ã / õ and cedilla ç dropped | ç, ã and õ carry meaning (coração, São Paulo); a missing mark changes the pronunciation and sometimes the word — critical on names and certificates. | Diacritics are set correctly and checked against the source, so names and terms are preserved. |
| Acordo Ortográfico misapplied | The 1990 Agreement aligned some spellings but did not unify the varieties. Applied wholesale, it produces inconsistent or wrong forms for the target. | We apply the current orthography correctly for the chosen variety, not as a blanket switch. |
| False friends between DE and PT | Terms that look familiar diverge in law and administration; a literal rendering imports the wrong legal concept. | A specialist checks the terminology and keeps legal and administrative terms demonstrable, not literal. |
| PALOP usage overlooked | The African PALOP countries (Angola, Mozambique and others) use European Portuguese with local administrative terms. Treated as generic PT-PT, some references miss. | We set the terminology for the specific target country, including the PALOP states, not a generic European default. |
| Certification abroad ≠ German authorisation | A German court-authorised translator is not automatically admitted in Portugal or Brazil, and the apostille and local forms differ by country. | We clarify which country the document is for and set the right form; Portugal and Brazil are Hague parties, so we check the apostille in advance. |
