As the vehicle owner, what change must you report to the relevant licensing authority?

In German traffic law, when you own a vehicle, you are required to notify the licensing authority if certain personal details change. Specifically, you must report changes to your home address and your name. This ensures that official records are accurate and correspondence reaches you correctly. However, changes to your third-party insurance are not directly reported by you to the licensing authority; instead, insurance companies handle their own notifications. Therefore, always remember to inform the authority about changes in your address or name to comply with legal requirements.
