| Tigrinya treated as Amharic | Tigrinya and Amharic share the Ge'ez script but are separate, not mutually intelligible languages. Hand a Tigrinya document to an Amharic translator "because it's the same letters" and you get mistakes or blanks. | We confirm the source language first and assign a native Tigrinya specialist — kept separate from Amharic. |
| Wrong vowel order in the fidäl | Each Ge'ez character is a consonant in one of seven vowel orders; the shapes differ only slightly. Read the order wrong and the name, place or word changes — often silently. | Names and terms are read character by character in the correct order and checked against the passport or original. |
| Origin Eritrea / Tigray not recognised | Tigrinya certificates come from Eritrea or from Ethiopia (Tigray). Issuing authorities, date systems and the legalisation route differ; miss the origin and the authority name and date are placed wrongly. | We identify the origin from the authority, emblem and form language and render the official designations of the right country. |
| Ethiopian date copied 1:1 | Ethiopian (Tigray) certificates usually date in the Ethiopian calendar — 7–8 years behind the Gregorian, with 13 months. Carried over unchanged, age, majority or deadlines no longer add up. | Every date is converted transparently and, where useful, shown with the original; for Eritrean documents the system used there is applied. |
| Ge'ez numerals ፩ ፪ ፫ misread | Dates, file numbers and amounts can carry Ge'ez number signs (፩=1, ፪=2, ፲=10). Left in place or misread, the figure flips. | Ge'ez numerals are converted unambiguously to Arabic figures and checked digit by digit against the original. |
| Father's name filed as a surname | As in Ethiopia, the name is a given name plus the father's given name; there is no inherited family name. File the father's name as a "surname" and translation, passport and register drift apart. | The name parts are transferred exactly as in the passport and their function (given name / father's name) is explained — without inventing a family name. |
| Ge'ez punctuation overlooked | Tigrinya uses the word separator ፡ and the sentence stop ። instead of spaces and full stops. Careless copying or OCR splits or fuses words — names and numbers slip. | The source is captured character-exact; word separators and stops are set correctly so names, places and figures stay cleanly apart. |
