I will present a hypothetical example. Sale of a used car: the buyer and the seller enter into a contract of sale and purchase, but do not arrange for a transfer because the buyer wants to take out insurance with a personal agent. According to the law, the buyer has 15 days to arrange the insurance, during which time the old owner is liable for anything that happens to the car sold. Any damage caused by the buyer is covered by the seller's insurance, which seems unfair and illogical to me. How to insure the seller in such a case????
