V5C logbook explained — what to check and how to transfer ownership
What a V5C logbook shows, how to spot a fake, and how to tell the DVLA about a sale so ownership transfers to the new keeper correctly.
A V5C, often called the logbook, is the document that records a car's registered keeper, its technical details and its history of keepers with the DVLA. It does not prove who legally owns the car. Selling or buying a used car in the UK, both parties need to get the V5C right, because a mistake here can leave the seller liable for a car they no longer have or leave the buyer unable to tax and drive it.
What is a V5C logbook?
The V5C is issued by the DVLA and lists the registration number, make, model, colour, engine size, VIN (chassis number), first registration date, and the name and address of the registered keeper. It also has a new keeper supplement, called the V5C/2, which the seller tears off and hands to the buyer at the point of sale.
The V5C is proof of who the DVLA has recorded as keeper, not proof of legal ownership. Ownership is usually shown by other documents: a purchase invoice, a finance agreement, or a hire purchase settlement letter. Someone can be the registered keeper without owning the car outright, for example if it is on finance.
Does the V5C prove ownership?
No. The V5C proves who is registered as keeper for tax and correspondence purposes. Legal ownership can sit with a finance company even while someone else is the registered keeper. This is exactly why a vehicle history check for outstanding finance matters as much as checking the V5C. Before you commit to a used car, run through the full used car buying checklist and see our guide on checking outstanding car finance.
What should I check on a V5C before buying?
- Match the VIN. The VIN on the V5C should match the VIN on the car, usually stamped at the base of the windscreen and often under the bonnet or in the door sill area too.
- Match the registration number on the document to the plate on the car.
- Check the watermark. A genuine V5C has a DVL watermark visible when held up to the light. If it looks flat, photocopied or printed on plain paper, walk away.
- Check the document reference number and date of issue. A very recently issued V5C on an older car is not automatically a problem, but ask why. It can mean a replacement was ordered after the original was lost, or that the car has recently changed keeper.
- Check the seller's name and address match the V5C, and match their ID. A private seller should be selling from the address shown on the document. If they cannot show any matching ID, treat that as a warning sign.
- Check the number of previous keepers. Several keepers in a short space of time can point to a car that people keep passing on because of a recurring problem.
- Check the serial number sequence. Genuine V5Cs have the document reference number printed in red along the top edge. Fresh, non-consecutive-looking print or a document that looks reprinted is a red flag.
None of these checks confirm outstanding finance or write-off history, so pair them with a full vehicle history check. Our guide comparing an HPI check with MOT history explains what each type of check actually covers.
How do I tell the DVLA I have sold my car?
The seller is responsible for notifying the DVLA of a sale. This is done in one of two ways:
- Online, using the 11-digit reference number from the V5C, which is the quickest route.
- By post, filling in section 6 of the V5C (sometimes still called the "new keeper" section on older documents) and sending it to the DVLA, while giving the buyer the V5C/2 new keeper supplement.
The buyer then receives a new V5C in their own name, usually within 5 to 7 working days when done online, though postal notifications can take up to 4 weeks. Until the new V5C arrives, the buyer can still drive and tax the car using the New Keeper Supplement (V5C/2) reference. The seller should keep the confirmation, or a copy of the posted section, as proof they told the DVLA of the sale and the date.
Failing to notify the DVLA promptly matters because until the change is processed, the previous keeper can still receive fines, tax reminders or correspondence linked to the car. Read our full guide on selling a car privately in the UK for the step-by-step sale process, including what to do with the sale receipt.
What if the seller has no V5C?
Treat this as a serious warning sign, not a minor inconvenience. A missing V5C can mean:
- It has genuinely been lost, in which case the seller should be able to explain and ideally show they have applied for a replacement.
- The car is not really theirs to sell.
- The car has an undeclared finance agreement or other issue the seller does not want checked.
If a seller offers to sell without a V5C, or says one is "on its way" with no evidence, do not hand over money or the car. A genuine seller can apply for a replacement V5C, which costs £25 and can be done online or by post, and should be willing to wait for it before completing the sale. If you have already agreed a price and the seller is trustworthy and known to you, it is still safer to wait for the replacement document than to proceed on trust alone.
What if I've lost my V5C?
Apply for a replacement directly with the DVLA, either online or by post. It costs £25 and is sent to the address the DVLA already holds on file for the registered keeper, so you cannot use this route to change the address at the same time as a first-time replacement without extra steps. If you are about to sell the car, get the replacement sorted first rather than trying to sell without it.

Frequently asked questions
Is a V5C the same as a logbook?
Yes. "Logbook" is the common name for the V5C registration certificate. They refer to the same document issued by the DVLA.
Can I drive a car without a V5C?
You can drive a car you have just bought using the New Keeper Supplement (V5C/2) reference while the full V5C is processed, provided the car is taxed and, where required, has a valid MOT. You should not buy a car where the seller has no V5C and no explanation for its absence.
How long does a V5C transfer take?
Notifying the DVLA online is usually processed quickest, with the new V5C normally arriving within 5 to 7 working days. Postal notifications generally take longer, typically up to 4 weeks.
Does the V5C show if a car has finance owing on it?
No. The V5C only shows the registered keeper and vehicle details, not finance status. Always run a vehicle history check to see if there is outstanding finance before you buy.
What should I do with the V5C after buying a car listed on Motofly?
Check the VIN, watermark and seller details as described above before you pay, then complete the DVLA notification with the seller so the new V5C is issued in your name. Keep the New Keeper Supplement safe until the full V5C arrives. Browse used cars on Motofly with MOT history and tax status already shown on every listing.
