| Montenegrin treated as Serbian | The two are close, but Montenegrin is a standard language of its own with its own Pravopis. Serbian material misses the Montenegrin norm — and, for Montenegrin authorities, the brief. | We translate exclusively into standard Montenegrin, to the current Pravopis, and keep it cleanly apart from Serbian. |
| The letters Ś and Ź resolved or dropped | The 2009 Pravopis introduced Ś and Ź for soft sibilants (śever, iźutra). Written as sj/zj or omitted, the text falls short of the current norm. | We set Ś and Ź correctly in Latin (and с́/з́ in Cyrillic) to the current orthography. |
| Latin and Cyrillic mixed up | Both scripts are official; the receiving body may expect one or the other. The wrong script, or a mix, looks wrong on an official document. | We fix the target script in advance and hold it consistently through the document. |
| Ijekavian base overwritten | Montenegrin is consistently ijekavian (mlijeko, not mleko). An ekavian form imported from Serbian breaks the norm. | We keep the ijekavian reflex throughout, as the standard requires. |
| Seven cases and vocative flattened | Montenegrin has seven cases including the vocative, three genders and verbal aspect. Rebuilt from German word order, relations and address in an official text go wrong. | We write from Montenegrin case grammar, with correct endings and aspect, not reconstructed from German. |
| Outdated conventions used | Because the norm is young, older or ad-hoc conventions circulate. Using them diverges from the current Pravopis the authority applies. | We work to the current Pravopis and verify terminology, not to superseded conventions. |
| Certification abroad ≠ Austrian authorisation | A Austrian court-sworn translator is not automatically admitted in Montenegro, and the apostille and local forms differ. | We clarify where the document applies and set the right form; Montenegro is a Hague party, so we check the apostille in advance. |
