If the V5C logbook does not check out, stop the sale right there. No other document tells you more about a vehicle's identity - and no other document is more commonly faked.
What Is the V5C Logbook?
The V5C logbook is the vehicle registration certificate issued by the DVLA. Every road-legal vehicle in the UK has one. It records the registered keeper, the vehicle's identity details, and its registration history.
The name "logbook" is informal but widely used. The official name is V5C. You will hear both used interchangeably.
The V5C logbook is the first document you should check when viewing any used car. It takes five minutes to examine properly.
What the V5C Logbook Contains
The V5C records:
- The registered keeper's name and address
- The vehicle make, model, and colour
- The VIN (Vehicle Identification Number)
- The engine number and size
- The date of first registration
- The number of previous keepers (not their names)
- A unique 11-digit document reference number
The number of previous keepers and the dates of registration changes are important context when assessing a vehicle's history.
What the V5C Does Not Prove
The most important thing to understand: the V5C logbook is not proof of ownership.
The registered keeper is the person responsible for taxing and licensing the vehicle. That person is not necessarily the legal owner. A fleet operator may be the keeper while a company director drives the car. A finance company may retain legal ownership while the customer is listed as keeper.
If a seller claims the V5C proves they own the car, they are wrong. Run a finance check to confirm no outstanding hire purchase, PCP, or logbook loan exists against the vehicle.
A full check at check.bad-drivers.uk covers finance, stolen markers, and write-off records alongside keeper history - everything the V5C will never show.
How to Check the V5C Logbook When Viewing a Car
Do this before any money changes hands.
Check the VIN. The VIN on the V5C must match the VIN stamped on the vehicle. It is on a plate in the engine bay, on a sticker inside the driver's door frame, and visible through the windscreen at the base of the dashboard on the driver's side. All three should match each other and the V5C.
Check the engine number. It is stamped on the engine block. Location varies by manufacturer. Compare it to the V5C.
Check the colour. Simple, but regularly missed. The V5C colour should match the car in front of you.
Check the document reference number. It must be 11 digits. Fraudulent V5Cs often get this wrong.
Check the watermark. Hold the V5C to the light. You should see a DVA crown pattern throughout the paper. Genuine V5Cs are printed on security paper. Photocopied or printed fakes will not have it.
Check for handwritten changes. Any crossing out or handwritten alterations are invalid. The DVLA issues a new certificate for any changes.
Red Flags on a V5C Logbook
Multiple keepers in a short time. A car that has had four or five keepers in three years needs a clear explanation.
Current keeper registered very recently. If the seller only registered the car days before listing it, ask why.
Address mismatch. If the V5C address is completely different from where the seller says they live, push for an explanation.
No V5C at all. A lost logbook is sometimes genuine. It is also a common tactic when a car is stolen or cloned. Do not complete a purchase without one. Ask the seller to apply for a replacement (form V62) before the sale.
What Happens at the Point of Sale
When you buy a car, the seller must complete the relevant section of the V5C and send it to the DVLA. You should receive a new V5C in your name within a few weeks.
Keep the green new keeper slip (section 6) from the V5C at the time of purchase. This is your proof that you are the new keeper while the DVLA updates its records. You will need it for taxing the vehicle.
FAQ
What is a V5C logbook?
The V5C logbook is the vehicle registration certificate issued by the DVLA. It records the registered keeper, vehicle identity details, and registration history. It is not proof of ownership.
Does the V5C prove ownership of a car?
No. The V5C records the registered keeper, not the legal owner. A finance company may own the car while the driver appears on the V5C. Always run a finance check alongside checking the V5C.
What should I check on a V5C logbook before buying?
Check the VIN matches the vehicle, the colour matches, the keeper address matches the seller's location, and the document reference number is 11 digits. Hold it to the light to check the DVA crown watermark. Any handwritten changes invalidate the document.
