Cyrillic Script & Transliteration Issues
Bulgarian uses a Cyrillic alphabet with characters like Ъ (representing a vowel, unlike Russian where it's a hard sign) and Щ (pronounced "sht" in Bulgarian, not "shch" as in Russian). Misidentifying Bulgarian as Russian and applying Russian transliteration rules causes name errors in court records and immigration filings.
Post-Communist Administrative Terminology
Bulgarian legal and civil documents retain terminology from the communist era — references to "народен съвет" (people's council), "ТКЗС" (collective farms), and older document formats. Interpreters must accurately explain these historical institutional references when they arise in testimony about document provenance or personal history.
EU vs. National Document Formats
Since Bulgaria's 2007 EU accession, documents may be issued in EU multilingual format or traditional Bulgarian format. Interpreters must understand both systems and recognize the different administrative authorities — община (municipality), ГРАО (GRAO civil registry), and НЗОК (National Health Insurance Fund) — referenced in testimony.
Definite Article Suffixation
Bulgarian uniquely attaches definite articles as suffixes with three demonstrative forms: "документът" (the document-this), "документа" (the document-that). In legal testimony, witnesses may use different article forms for the same concept, and interpreters must recognize these as referring to the same entity without confusion.
