Case: Aunt Zhang bought a second-hand car from Xiao Liu and asked Xiao Liu to go with her to go through the car ownership registration formalities. Xiao Liu claimed that he had lost the relevant documents, and the transfer procedures were very complicated, so he could obtain the ownership of the car without going through the registration procedures for car transfer. So, can the ownership be obtained without registration when the car is transferred? According to this case, ownership can be obtained. Article 224 of the Civil Code stipulates that the establishment and transfer of the real right of movable property shall become effective upon delivery. Therefore, when the seller delivers the automobile to the buyer in the automobile sales relationship, the buyer obtains the ownership of the automobile. However, it should be noted that according to the provisions of Article 225 of the civil code, the establishment, change, transfer and extinction of the property rights of ships, aircraft and motor vehicles shall not oppose bona fide third parties without registration. Therefore, there are risks if registration is not handled. Therefore, Aunt Zhang should still advocate to handle the transfer registration.
