| Transliteration: ISO 843 vs. ELOT 743 vs. passport | The registry office wants ISO 843 (Γεώργιος → Georgios), the passport carries the ELOT 743 form, relatives write "Yorgos" or "George". Where the versions diverge, the authority doubts the identity. | We apply the required standard and note the passport spelling, so all forms are assigned to the same person. |
| Katharevousa read as modern Greek | Documents into the 1970s are often in the archaic Katharevousa, with grammar and vocabulary that differ from today's Dimotiki. Read as modern Greek, terms and endings are misconstrued. | Native specialists familiar with Katharevousa render older certificates in their historical register, not by modern analogy. |
| Polytonic accents and breathings dropped | Older and church documents use the polytonic system (several accents, the rough and smooth breathings). Stripped or misread, a word or name shifts. | The polytonic marks are read correctly and their bearing on the word retained. |
| Final sigma ς confused with σ | Greek writes σ inside a word and ς at the end (Οδυσσέας). Mixed up, a name looks wrong to the receiving office. | The correct sigma form is set by position, and names checked character by character against the source. |
| Cases and genders flattened | Greek has three genders and four cases; endings carry who acts on whom. Rebuilt from German word order, relations in an official text go wrong. | We write from Greek case grammar, with the correct endings, not reconstructed from German. |
| Greek ≠ Cypriot administrative usage | Greece and Cyprus share the standard language but differ in some administrative terms and document forms. The wrong convention misses the receiving body. | We set the terminology and document form for the target country — Greece or Cyprus — deliberately. |
| Certification abroad ≠ German authorisation | A German court-authorised translator is not automatically admitted in Greece, and for use there the apostille question and local forms differ. | We clarify where the document applies and set the right form — a certified translation for Germany, or the route valid in Greece or Cyprus, with the apostille checked in advance. |
