Before you pay for a used car, check that the V5C logbook has a "DVL" watermark, that its serial number isn't in a range GOV.UK lists as possibly stolen, and that the VIN, engine number and keeper's address all match the car and the seller. Then make sure the seller tells DVLA about the sale and hands you the green new keeper slip. Vehicle tax doesn't transfer, so you need to tax the car yourself before driving it away.
What the V5C does and doesn't prove
The V5C, or vehicle log book, records the registered keeper: the person responsible for taxing the car and dealing with DVLA. It doesn't prove ownership. A car on hire purchase or PCP, a lease car or a company car will have a perfectly normal V5C even though a finance company, leasing firm or employer owns it. That's why a V5C check sits alongside a finance check, not instead of one. See our guide to outstanding car finance checks.
What the V5C can do is tell you whether the paperwork, the car and the seller belong together. If any of the three don't match, stop.
V5C checks before you hand over money
1. Watermark and serial number
GOV.UK tells buyers to look for a "DVL" watermark, visible when you hold the page up to the light, and to check the serial number. It lists two ranges of V5Cs that might be stolen:
- BG8229501 to BG9999030
- BI2305501 to BI2800000
If the serial number falls within either range, don't buy the car and call the police as soon as it's safe, on 101 or on 999 in an emergency.
2. Is it the latest logbook?
Run the reg through the free DVLA vehicle enquiry. It shows the date the last V5C was issued. That date should match the issue date printed on the logbook you're holding. If DVLA issued a newer one, the document in front of you has been replaced, perhaps after being reported lost, and you need to know why.
3. Does the V5C match the car?
GOV.UK says to check that the VIN and the engine number match the logbook. Compare:
- The registration number on the plates.
- The VIN, at the bottom of the windscreen, on the VIN plate and stamped into the body. All of them should match the V5C exactly.
- The engine number, if you can find it. The handbook or a garage can show you where it is.
- Make, model, colour, engine size and fuel type. A colour change should be recorded on the V5C.
- The date of first registration, which should also match the DVLA enquiry and the car's age in the advert.
4. Does the V5C match the seller?
- The keeper's name should match the seller's photo ID.
- View the car at the address on the V5C, not in a car park or lay-by.
- If the seller isn't the registered keeper, ask why. "I'm selling it for a friend" means you need to speak to the keeper.
5. Does the keeper history fit the story?
The V5C shows the number of previous keepers, and its issue date usually marks the last change of keeper. A seller describing "the family car for years" whose logbook was issued six weeks ago is a reason to dig deeper. Several short ownerships can also point to a car people keep getting rid of.
6. Insist on the original
Only accept the original paper V5C. A photo or photocopy proves nothing. GOV.UK also tells sellers not to share the document reference number or copies of the logbook, because they can be used for fraud. Don't ask for them before you view, and be cautious of a seller who sends them unprompted.
Do the V5C check before the test drive, not after. Once you've driven the car and agreed a price, it's much harder to walk away from a document that doesn't look right.
When there's no V5C
You'll hear "it's in the post", "it's with DVLA" or "I've lost it". Sometimes that's true, but without the logbook you can't do any of the checks above, and it's a common feature of stolen and cloned car sales.
- The safest option is to wait until the seller has a replacement. Online or by phone it usually costs £25 and takes 5 to 7 working days, according to GOV.UK.
- If you buy anyway, you'll need to apply for a new registration certificate yourself on form V62. You're relying entirely on the seller's word about who they are and what the car is.
How change of ownership works
What the seller does
In a private sale, GOV.UK says the seller must:
- Give you the green "new keeper" slip from the V5C.
- Tell DVLA about the sale, giving your full name and address.
The quickest way is online, and the seller can do it on their phone while you're there. DVLA updates the record straight away and emails a confirmation. The online service can't be used if the seller has already posted the V5C. The seller should also remove any private number plate they want to keep before the sale.
Ask to see the confirmation before you leave. If the seller insists on posting the V5C later, write down the date and keep your receipt, because until DVLA's record changes, fines and tax reminders can still go to them, or end up with you.
What you do as the new keeper
- Tax the car before you drive it. GOV.UK is explicit that the tax isn't transferred when you buy a vehicle. Use the reference number on the green new keeper slip at the online vehicle tax service, or declare the car off the road (SORN). The seller's tax is cancelled and they get a refund for any full months left.
- Insure it before you drive it, including the drive home. You can check a car's insurance status on the Motor Insurance Database.
- Wait for your new V5C. DVLA posts it to the address the seller gave. Chase DVLA if it hasn't arrived after a few weeks, because if you leave it too long you may have to pay for a replacement.
- Set an MOT reminder. Cars need an MOT every year once they're three years old.
Buying from a dealer
A dealer handles the DVLA notification through the motor trade service, but you still need to tax and insure the car before driving it. Ask the dealer to show you the V5C before you sign. A dealer who has only just bought the car may not have a V5C in their own name, which is normal, but the document should still pass every check above.
Using the V5C with other checks
The V5C is one part of the paperwork. Before you pay, also:
- Check the MOT history, which shows every result and the recorded mileage. Our guide to reading MOT history explains what to look for.
- Run a stolen check. See how to check if a car is stolen.
- Consider a paid history check for finance, write-offs and mileage records. carVertical accepts a reg or VIN and its GB report can include these where records exist, along with photos from past listings. One report costs £31.99 with the code KALOGB (£39.99 without), and if you're choosing between three cars, a three-report pack works out at £16.79 a car with the code.
Done in that order, the free checks catch most problems before you've spent anything, and the paid check fills in what DVLA and DVSA don't record.
Frequently asked questions
Is the V5C proof of ownership?+
No. The V5C shows the registered keeper, the person responsible for the car with DVLA. That isn't always the legal owner, for example when the car is on finance or leased.
What are the stolen V5C serial numbers?+
GOV.UK lists two ranges of V5C serial numbers that may be stolen: BG8229501 to BG9999030 and BI2305501 to BI2800000. If the logbook falls in either range, don't buy the car and contact the police.
Does the vehicle tax transfer when I buy a used car?+
No. Tax isn't transferred to the new keeper, so you must tax the car before you drive it, using the reference number on the green new keeper slip. The seller gets a refund for any full months left.
Should I buy a car without a V5C?+
It's best not to. Without the logbook you can't check the watermark, serial number or keeper details, and you'll need to apply for a new one on form V62. A genuine seller can get a replacement from DVLA first.
Who tells DVLA about the change of ownership?+
In a private sale the seller tells DVLA, ideally online while you're there, and gives you the green new keeper slip. DVLA then posts a new V5C to you.
