The V5C logbook explained

The V5C, usually called the logbook, is the vehicle's registration certificate. It shows who is responsible for taxing the car, not who owns it.

By the VehicleFile editorial team · Updated · 2 min read

What is on the V5C

  • The registration number and the vehicle identification number (VIN).
  • The name and address of the registered keeper.
  • Make, model, colour, engine size, fuel type and CO2 emissions (section V.7), which decide the vehicle tax rate.
  • The date of first registration and the number of previous keepers.
  • The 11-digit document reference, which you need to tax or SORN the vehicle online.

The logbook also states that the registered keeper is not necessarily the legal owner. A car on finance, for example, belongs to the lender until it is paid off.

When you sell a car

  1. Tell DVLA online using the 11-digit reference. This is instant and free.
  2. Give the buyer the green new keeper slip (V5C/2). Do not give them the rest of the logbook if you told DVLA online. Destroy it.
  3. Any full months of tax are refunded to you automatically. Cancel any Direct Debit only after DVLA confirms.

When you buy a car

  • Check the VIN on the logbook matches the VIN on the car, usually at the base of the windscreen and on a plate in the door frame.
  • Check the name and address match the seller, and look for the DVLA watermark.
  • Make sure you get the new keeper slip. You need its 12-digit reference to tax the car before you drive away.
  • Your new logbook should arrive within 4 weeks. If it does not arrive within 6 weeks, contact DVLA.

Changing your name or address

You must update the V5C if you move or change your name. Address changes can be done online for free. You can be fined up to £1,000 for not telling DVLA.

Lost or damaged logbook

Apply for a replacement online, by phone or by post using form V62. It costs £25. If you are the registered keeper and your details have not changed, you can usually apply online and get it within about 5 working days.
