(1) Where a person has registered with a registration authority, this authority is to inform the registration authority responsible for the previous place of residence and the registration authorities responsible for the person’s other residences thereof by transferring to them the data referred to in section 3 (1) nos. 1 to 18 of the person in question (acknowledgement). As regards persons moving to Germany from abroad, the registration authority responsible for the last residence in Germany is to be informed as the registration authority responsible for the previous place of residence. The data are to be transferred without delay and no more than three working days after registration; section 10 (2) applies accordingly.
(2) The data transferred are to be processed by the registration authority responsible for the previous place of residence without delay. The registration authority responsible for the previous place of residence is to inform the registration authority responsible for the new place of residence without delay, and no more than three working days after receiving the acknowledgement, about the facts referred to in section 3 (2) no. 1, no. 2 (d), nos. 3, 4, 7, 8 and 11 and whether the data referred to in sentence 1 differ from the previous data (assessment of the acknowledgement). If registration authorities in the same Land are involved, Land law may provide for more detailed regulations on the data transfer.
(3) If the data referred to in section 3 (1) and (2) nos. 4, 7 and 8 are updated, the registration authorities responsible for any other residences of the data subject are to be informed without delay if the data are necessary for them to carry out their tasks. If a person required to register on whom data of the persons referred to in section 3 (1) nos. 9, 15 and 16 are stored outside the area of responsibility of the registration authority dies or moves away, the registration authority responsible for these persons is to be informed of the update without delay.
(4) If the registration authority enters a block on releasing information within the meaning of section 51 in the population register, or if it lifts such a block, it is required to inform the registration authority responsible for the last previous residence or the new residence and the registration authorities responsible for any other residences thereof without delay. These registration authorities are to enter the block on releasing information within the meaning of section 51 in the population register without delay and are to delete it when it has been lifted. Sentences 1 and 2 apply accordingly to conditional blocks on releasing information within the meaning of section 52, with the proviso that such blocks are not lifted.
(5) If any international treaties provide for a procedure for sharing such information with bodies abroad, the agreements in these treaties take precedence over the provisions of subsections (1) to (3).
(6) Data transfers and the sharing of information between registration authorities are free of charge.
