V5C Logbook Explained: Your Vehicle Registration Document

#What the V5C actually is

The V5C is the registration certificate held by DVLA, with a printed version sent to the registered keeper. It does not prove ownership. It only records who is responsible for the vehicle for tax, fines, and DVLA correspondence. A keeper can be different from the legal owner, for example when a car is on finance or used as a company car.

#How to spot a real V5C

A current V5C has a red and blue front cover, watermarked paper, and a holographic DVLA logo. There are two visible printed numbers on the front: the registration mark, and the V5C document reference number used to update online. Old style blue V5Cs are no longer valid. If a seller hands you one, ask for a fresh one before completing the sale.

#Sections you need to know

The V5C is split into several lettered sections. You do not need to memorise every one but a handful matter when buying or selling.

• Section 1: registered keeper details. Must match the seller you are speaking to.
• Section 2: new keeper details, completed by the buyer when the car changes hands.
• Section 6: declaration. Both seller and buyer sign here.
• Section 9: green new keeper supplement. Hand this to the buyer at the moment of sale.
• Section 10: yellow sell-or-transfer slip. Sent to DVLA by the seller.

#When you must update it

You must tell DVLA whenever any of the registered details change. There is no fee for most updates and almost all can be done online with the 11 digit reference number on the V5C. The legal duty is on you as keeper. Failing to update can lead to a £1,000 fine.

• You sell or transfer the vehicle.
• You buy or are given a vehicle.
• You change address.
• You change name (after marriage for example).
• You modify the vehicle in a way that changes its specification, including engine swap or colour change.
• You scrap or export the vehicle.

#Selling a car the right way

When you sell, complete sections 2, 6 and 9 with the buyer. Hand the buyer the green slip from section 9, then go online at gov.uk to notify DVLA of the sale, or post the rest of the V5C to DVLA. The buyer cannot tax the car without that green slip, so make sure they leave with it.

You will get an automatic refund for any whole months of remaining tax. The new keeper gets a fresh V5C in the post within four weeks. Until that arrives, the green slip is their proof of keeper status.

#Buying a car the right way

Always inspect the V5C before paying. Match the VIN on the V5C to the VIN stamped on the chassis (usually under the bonnet or on a panel by the windscreen) and to the engine number. Check the previous keeper count, the recorded mileage at last MOT (free at gov.uk), and any V5C reference numbers that look altered or laminated.

A common scam is a stolen car sold with a forged V5C cloned from a similar legitimate vehicle. Always run an HPI or DVLA vehicle enquiry check on the registration before paying.

#Changing address or name

Move house and you must update the V5C with the new address before the next tax renewal. Do this online with the V5C reference number. There is no fee. If you do not update and a parking or speeding fine arrives, it goes to the old address and you will not see it until enforcement chases you.

Change of name, for example after marriage, is also free. You may need to send a marriage certificate or deed poll for verification.

#Engine, colour and modification changes

Cosmetic colour changes (a respray) and major mechanical changes (engine swap, body kit, conversion to LPG) all need to be reported. DVLA may want photographs and a receipt. Failing to report changes can lead to insurance issues and potentially a Q registration if the changes are extensive.

#Lost or damaged V5C

If you lose your V5C or it is destroyed, apply for a replacement at gov.uk. The fee is £25 and the new document arrives in around five working days. If a replacement V5C arrives suspiciously fast, ask why before you accept it as proof of legitimacy.

#How the V5C ties to other paperwork

The V5C, your insurance certificate, your MOT and your tax all join up. Insurers cross-check the registered keeper. DVLA cross-checks tax against the V5C. The MOT history is filed against the same VIN. Keep them aligned and you avoid almost all of the paperwork problems that cause first-year drivers grief.
