Question about re-registration of a car within the family

Hello, I want to take over the vehicle from my father. The registration plates can remain on the car, the insurance is to be changed. The following is required: Registration certificate Part II (vehicle letter) Registration certificate Part I (vehicle note) Current proof of valid main examination (HU) (car new not necessary) Registration plates for registered vehicles (Not necessary because I keep the registration plates?) Electronic insurance confirmation number (eVB) Eligibility (SEPA or combined mandate with IBAN and BIC) for tax passport including registration confirmation (no identity card available). Do I really need a registration confirmation? So now my questions: Is the list complete? Does my father have to go with you? He can’t go with you due to illness. Is a authorisation sufficient or do I need nothing because I have the vehicle license? Many thanks for your efforts Mando
