Brazil vehicle transfer: procedures for sale communication

In Brazil, the sale of a vehicle requires formalizing the transfer with the relevant traffic department (Detran) to update public records and define legal responsibilities. According to the Brazilian Traffic Code (CTB), simply handing over keys or signing a private contract does not automatically update the vehicle's registration.

To avoid liability for future traffic violations or debts, the seller should perform a sale communication through Detran or an integrated notary office. While the buyer has 30 days to complete the registration, the seller should ensure the communication is recorded to prevent being held jointly responsible for penalties incurred after the sale. Documentation such as the signed transfer document (ATPV-e or physical CRV), protocols, and proof of delivery should be retained.
