1. Formalities before Leaving
Before you leave Stuttgart you have to de-register at the Bürgerbüro with the green cancellation form (Abmeldung) which is available at any Bürgerbüro.
Check canceling formalities with your private insurance company. If you quit working for the University of Stuttgart as an employee, the statutory health insurance will automatically expire, too.
Before you leave Stuttgart you should consider closing your bank account. Please go to the bank in person and return your bank cards.
