However, if the transfer formalities are not handled, the sales agreement between the two parties is only valid between the buyer and the seller and cannot be against others. That is to say, in real life, if the transfer formalities are not handled, others can think that the vehicle still belongs to the seller, and there are other legal relationships with the seller such as lease and mortgage around the vehicle. At this time, the rights of car buyers will not be protected.
Therefore, it is recommended to handle the transfer formalities in time after purchasing the vehicle to avoid unnecessary troubles.
