When buying and selling vehicles, as long as both parties sign a sales agreement, the seller will deliver the vehicle to the buyer, and the contract will come into effect, and the ownership of the vehicle will also be transferred to the buyer.

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.
