According to the latest changes in the law, the deregistration of the secondary residence may again be officially carried out at the registration office of the secondary residence,
but it may also continue to be carried out at the registration office of the future sole or main residence, e.g. a secondary residence in Koblenz may again be deregistered at the Koblenz registration office.
