What should I do with the V5C when I sell my car?

GOV.UK says sellers must notify DVLA of the buyer's full name and address. When the vehicle stays in the UK, the buyer gets the green new-keeper slip so they can tax and register the vehicle.

DVLA also warns sellers not to share photographs or copies of the V5C document reference number before sale because it can be misused to obtain fraudulent documents.

Keep the DVLA confirmation that you are no longer the keeper. That confirmation is important if parking, tax or enforcement correspondence later arrives for events that happened after the sale.

For 'What should I do with the V5C when I sell my car?', keep a written record of the exact vehicle, seller details and checks you relied on before payment. That evidence is far more useful later than relying on memory or verbal promises.
