For example when you apply for Turkish citizenship your father's name is let's say Philipos, and you have a father with that name until he also becomes a Turkish citizen with a new name let's say Filip. Now you have to update your ID.

I've heared that some police or military people change their name because they killed many terrorists.

But the most comman provlem is with birth dates. Some of my friends had such birth dates in their IDs; 0.0.1984 or 5.12.1885 (should be 1985). Why? Actually they have birth certificate in Bulgaria, even with hours. But when they become citizen of Turkey an idiot public service officer wrote wrongly to a paper, now you need to prove that you were born in that date with diplomatically certified and translated birth certificate that you have optained from your home country wich is possible but long and boring process. Instead they auto corect to middle of the year; 1.7.1984.

Especially some eastern places before 90s didn't wrote their birth dates because you know, is a "boring paper work" for them.

Or a parent says that their douther's name is Gizem but the public servant writes İzem.

This is why this country is called a developing country. They can't write something propery.
