hello, I sold a used car for the first time on 15.07.15, I had paid the fee for my car insurance until the end of the year in advance. on the same day I reported to the registration office AND the insurance (ADAC) the sale, with all the data of buyers and sellers including addresses, personal card numbers and signatures. in order to get to the paid insurance amounts the insurance requires the certification of the kfz registration office via the registration, this te Now informs me that although the car has been registered by me, it has still not been registered by the owner and you would only inform the insurance company after re-registration. I do not reach the buyer by phone. what should I do now? is there a time limit until you have to have registered the car after a purchase? why does the kfz registration office cause MIR problems? it is MIR only about the registration confirmation and that has been proven. How would you behave? Greetings
