In Berlin a person can leave the church only through the local court. The city’s service portal states: Der Austritt kann nicht online erklärt werden! The exit cannot be declared online. A declaration through an authorized person is not allowed. The fee is 30 euros.
In June 2021 the city administration of Karlsruhe answered a question from its council about waiting times. The average wait for an appointment to leave the church was about seven weeks. Before the pandemic it had been ten days.
