Question about death Father: Transfer of the SF class to mother or children?

Hello together, My father died 1 week ago and since my mother is full of grief, I take care of everything. Anyway, there is now a tricky situation because of my father’s car. It was registered to my father and the insurance just as only on him. My parents are immigrated to Germany in 1989, however, also the driver’s license from the country of departure was accepted, which is why my father had SF 30. My mother also had a driver’s license in our old home t, who has been recognized in Germany, but she has practically never driven a car in Germany. Accordingly, she has practically no driving experience, but I would not necessarily tie this to the insurance company now. Or am I obliged to tell the truth here? My sister is 29 and has SF 1/2 due to various incidents and I am 31 with SF 9 (also not completely harm free). That means we could both improve our SF if we take it from the father. It would be ideal if my mother would take over the SF 30 now (indicated that my father was driving primarily and that she was only “unpleasant” and that she would actually start driving for the next 7 years. I would also spend a few hours in the driving school (theory + practice) and we would also spend only a few hours in the driving school (theory + practice) and we would only spend a few hours in the driving school. n Buy automatic car to make it easier. But unfortunately my mother is undecided Now I have presented the facts and now the questions come to this: 1. I read that the insurance requires proof that spouses/children were also traveling with the insured vehicle. What should this look like? 2. Can my mother take over the SF 30 completely and use it also over the next 7 years? 3. Is it problematic if the insurance at the end of the yes Mres is terminated after the SF acquisition? Currently the car is sold and therefore there is no insurance requirement at the moment. 4. Can my sister or I take over the SF classes and what would it look like? Thank you
