| Belarusian treated as Russian | Belarusian is its own language, not a dialect of Russian. Given to a Russian translator, the result carries Russisms, wrong word choices and a spelling that Belarusian authorities immediately read as foreign. | The job goes to Belarusian native speakers who keep Belarusian and Russian forms reliably apart. |
| Orthographies mixed (Tarashkevitsa vs Narkamauka) | Classical and official spelling write many words differently (e.g. клясычны vs класічны). Mixed together, the text reads inconsistent and looks doubtful to an authority. | We fix the target orthography before the project and keep it consistent throughout — classical or official, depending on purpose. |
| The letter ў confused | The short u (ў, "u karotkaje") is its own letter, not у or в. Overlooked, the word changes — in a name, a factual error against the ID. | ў is set correctly and, in names, checked character by character against passport and original. |
| Name romanisation: wrong scheme | The registry office wants a letter-faithful romanisation; the official Belarusian scheme (Łacinka-based) writes Віцебск → "Viciebsk", while a Russian-influenced passport reads "Vitebsk". If the forms diverge, the authority doubts the identity. | We apply the required scheme and note the passport spelling, so both forms are matched to the same person. |
| Akanne "corrected" (o instead of a) | Belarusian writes unstressed o as a (малако "malako"). "Fixing" it to the Russian молоко produces wrong Belarusian. | Belarusian spelling is kept, rather than importing Russian forms. |
| Dzekanne/tsekanne dropped | Before soft vowels д becomes дз and т becomes ц (дзень not Russian день). Missing, the word is not correctly written Belarusian. | Dzekanne and tsekanne are applied by the rules — self-evident to a native speaker. |
| Place names Russian instead of Belarusian | Toponyms circulate in Belarusian and Russian-derived forms (Мінск/"Minsk", historically Менск/"Mensk"; Гомель/"Homieĺ"). The wrong form in a certificate is a factual error. | Place names are set in the officially required form and, where needed, given an explanatory note. |
| Soviet/Russian-language records misread | Many certificates from the BSSR or Soviet era are Russian-language or carry different authority names and forms than today's Belarusian documents. Not knowing the formats, stamps and endorsements get transferred wrongly. | Our translators know Soviet and present-day, Russian and Belarusian templates, and render authority names, stamps and marginal notes correctly. |
