The V5C Logbook Guide: What Buyers and Sellers Need to Know

The V5C Logbook Guide: What Buyers and Sellers Need to Know

The V5C — commonly called the "logbook" — is the most important document linked to a vehicle in the UK. Issued by the DVLA, it tracks the registration and taxation history. But it's also the source of much confusion, and mistakes can be costly for both buyers and sellers.

Whether you're buying a used car or selling your own, knowing what the V5C is — and what it isn't — matters.

The Most Important Fact: The V5C is NOT Proof of Ownership

This is the biggest misconception in the used car market. The V5C states it clearly on the front cover: "This document is not proof of ownership."

The V5C records the registered keeper — the person responsible for taxing the car, getting it MOT'd, and paying speeding fines or parking tickets. The registered keeper and legal owner are often the same person, but they don't have to be.

For example, if you buy a car on finance (HP or PCP), you're the registered keeper (your name is on the V5C), but the finance company is the legal owner until the debt is settled. This is why a premium history check is essential — if you buy from a registered keeper who still owes finance, the finance company can legally repossess it from you. Verify a vehicle's details for free before you view any car to cross-reference the V5C information against the official MOT and tax records.

For the Buyer: Checking the V5C

When you view a used car, checking the V5C is vital. Never buy from someone who "can't find" the logbook.

1. Verify the Watermark

The DVLA issues V5Cs on specific paper. Hold it up to the light and you should see a "DVL" watermark. This is a basic check against crude forgeries.

2. Match the Details

The V5C is the car's identity card. Make sure the details on the paper match the physical car:

• Vehicle Registration Mark (VRM): The number plate.
• Make and Model: Does it match?
• Colour: Does it match the car? If it's been wrapped or resprayed and the V5C hasn't been updated, that's a red flag.
• Vehicle Identification Number (VIN): This is crucial. Find the VIN on the car (usually through the bottom of the windscreen or stamped under the bonnet) and make sure it matches the 17-character string on the V5C exactly. A mismatch suggests the car could be cloned or stolen.

3. Check the Address

If you're buying privately, the address on the V5C should be where you're viewing the car. Buying from a layby or pub car park from someone whose address doesn't match the V5C is very risky.

4. What is the "New Keeper Slip"?

When you buy the car, the seller keeps the main V5C to notify the DVLA. They must give you the green "New keeper slip" (Section 10 or V5C/2). You need this to tax the car before driving it away. You can't legally drive on the previous owner's tax.

For the Seller: Your Responsibilities

When selling, getting the V5C wrong can leave you liable for the buyer's future parking fines or speeding tickets.

1. Notify the DVLA Immediately

It's your legal duty to tell the DVLA the car has been sold. You can fill out the V5C and post it, but it's far safer and faster to do it online via GOV.UK.

You need the 11-digit reference number from the front of the V5C. Once done, the DVLA updates their records instantly and you get an email confirmation. Destroy the remaining V5C.

2. Give the Buyer the Green Slip

Detach the green "New keeper slip" and give it to the buyer. They need it to tax the car immediately.

3. Reclaiming Unused Tax

When you notify the DVLA, any full months of remaining vehicle tax are automatically refunded to you by cheque. Tax can't transfer to the new owner.

What if the V5C is Lost?

If you're selling and have lost your V5C, don't sell until you get a replacement. Apply online or by phone via the DVLA — it costs £25 and arrives within 5 working days.

If you're buying and the seller says the logbook is lost, walk away. You can apply for a new one using a V62 form, but then you have no way to verify the seller's identity or the car's true details at the point of sale.

The V5C is a simple document, but it needs careful handling. Treat it with the importance it deserves for a smooth, secure deal. Check any registration before you commit to a viewing — matching the V5C details against the official record is your first line of defence against logbook fraud.
