Pick the driving licence authority, not the ordinary registration counter, when you book, and come in person to sign.
Bring your old licence, identity card or passport with current registration evidence, and a biometric photograph. For an older paper licence issued elsewhere, obtain a Karteikartenabschrift from the issuing authority; ask Chemnitz about records from the former Volkspolizei-Kreisamt Karl-Marx-Stadt. The city says this extract is unnecessary for licences issued from 1 January 1999. Confirm the accepted photo format before using a passport-photo code.
