Kfz: Zulassungsbescheinigung Teil I (Fahrzeugschein)

The registration certificate part I has replaced the vehicle registration document. The person entered in the registration certificate Part I is the keeper of the corresponding vehicle. The term "keeper" originates from § 833 BGB. According to this, the holder is the person who uses the vehicle for their own account (i.e. pays the costs and can actually dispose of the vehicle; this is often not the owner of the vehicle. The registration certificate part II is therefore not proof of ownership, but ultimately only facilitates the registration process, as it is assumed that the person holding the registration certificate part II is authorized to dispose of the vehicle.
There is no general obligation to exchange the old vehicle registration certificate for the new registration certificate part II. A new vehicle registration certificate is automatically exchanged if a new one has to be issued anyway (e.g. because it has been lost, regardless of whether the old vehicle registration certificate is still available or if a new registration certificate Part I has to be issued.

Part I registration certificates (vehicle registration certificates) that have been invalidated will be returned to the owner after the vehicle has been taken out of service.

The transfer of entries in the "Remarks" field of the previous vehicle registration certificate to the new ZB I sometimes causes problems. In principle, the new field 22 of the registration certificate part I is used to transfer these entries. If there is not enough space there, a supplementary sheet is issued, sometimes also attached. Check that all information is transferred correctly when the new documents are issued and complain about any discrepancies as soon as possible.

If you instruct a third party to deregister your vehicle, they will need a written authorization from you; they must also present your identity document (in the original) to the registration office. The third party must have the correct identity document with them in order to identify themselves.

Contact the registration office in your district or city. Responsibility depends on the place of residence of the vehicle owner (main residence according to the identity card).

In the case of legal entities, it is the registered office of the main branch or the registered office of the branch; this also applies to a general partnership, limited partnership or a registered merchant.
