(1) There are no grounds for a registration requirement under section 17 (1) and (2) if a person who is registered at a residence in Germany moves into collective accommodation or other officially provided housing in order to
1. perform compulsory military service pursuant to the Compulsory Military Service Act (Wehrpflichtgesetz) or voluntary military service pursuant to the Act on the Legal Status of Military Personnel (Soldatengesetz),
2. perform federal volunteer service pursuant to the Federal Volunteer Service Act (Bundesfreiwilligendienstgesetz),
3. perform civilian alternative service pursuant to the Act on Civilian Alternative Service (Zivildienstgesetz),
4. perform a service as referred to in Division 4 of the Act on the Legal Status of Military Personnel,
5. serve in the Bundeswehr as a career service member or temporary career volunteer or as a police officer in the Federal or Land police, unless residing at the accommodation for more than 12 months,
6. take part as a public service employee in courses or specialised studies for basic or advanced training.
(2) Anyone who is registered in Germany in accordance with section 17 or section 28 and moves into a residence for a stay of no more than six months is not required to register or deregister at this residence. Anyone who has not moved out of this residence after six months have elapsed is required to register with the registration authority within two weeks. As regards persons who otherwise live abroad and are not registered in Germany in accordance with section 17 (1), this requirement applies after three months have elapsed.
(3) The exception to the registration requirement under subsection (2) does not apply to
1. ethnic German resettlers and their family members if they are assigned a place of residence pursuant to section 8 of the Federal Expellees Act (Bundesvertriebenengesetz) and
2. asylum applicants or other foreigners who temporarily move into a reception centre or other assigned housing.
To meet the registration requirement under subsection (2) in conjunction with sentence 1 no. 2, the body responsible for keeping the records of persons in reception centres may submit the data required for registration to the registration authority in the form of a list. A copy of the record kept pursuant to foreigners law may be submitted instead of a list. In both cases, submission in electronic form is permissible.
(4) As regards a person who has been deprived of his or her liberty by judicial decision, section 17 (1) does not establish a registration requirement as long as
1. the period of enforcement of the deprivation of liberty does not exceed three months or
2. the data subject is registered in Germany in accordance with section 17 or section 28 and the period of enforcement of the deprivation of liberty does not exceed 12 months.
Otherwise, the management of the detention facility is required to notify the registration authority responsible for the site of the detention facility within the two weeks following the person’s admittance and release; the data subject is to be informed. The notification contains the data to be included in the registration form. The notification takes the place of registration as required by section 23 (1).
