Short answer
Yes – in the UK the term “log book” is the common name for the V5C registration certificate issued by the DVLA. It records who the registered keeper is and provides the official vehicle details.
What the V5C (log book) actually contains
The V5C is a three‑page paper document that shows:
- The vehicle’s registration number, make, model and colour
- The VIN (Vehicle Identification Number) and engine size
- The name and address of the registered keeper
- Key dates such as the date of first registration
It does not prove legal ownership – that is established by a bill of sale or finance agreement – but it is the primary proof of who is responsible for road tax, MOT and insurance.
Other “log books” you might encounter
Dealers and owners sometimes keep a separate service log book that records oil changes, tyre rotations and other maintenance. That book is useful for assessing the car’s condition, but it is not a legal document and has nothing to do with registration.
Why the distinction matters when buying used
When you’re considering a used car, the V5C is the document you should check against the vehicle’s registration number. It lets you verify that the seller is the registered keeper and helps you spot red flags such as:
- Missing or altered V5C details – could indicate a stolen vehicle or an attempt to hide a previous write‑off
- Discrepancies between the V5C and the MOT history from the DVSA
- Outstanding finance that would appear on a finance check but not on the V5C
Running a full vehicle history check on motorpeek.com will cross‑reference the V5C data with the DVLA, DVSA, PNC and insurance write‑off databases, giving you a clear picture before you commit.
How to read the V5C correctly
Look for the “New Keeper” section (section 6) – it should be blank if the car is being sold. The “Registered Keeper” details (section 2) must match the seller’s ID. The “Vehicle Details” (section 1) should align with the information shown on the MOT certificate and any service records.
What to do if the V5C is missing or incomplete
A missing V5C is a warning sign. The seller can apply for a replacement V5C (V5C/2) from the DVLA, but you should request proof that the replacement has been issued before finalising the purchase. Never rely solely on a photocopy – ask to see the original document.

Frequently asked questions
Can I trust a photocopy of the V5C as proof of a car’s history?
A photocopy can be useful for reference, but it is not a legal document. Always ask to see the original V5C and confirm the details with a live vehicle history check.
What is the difference between a V5C and a V5C/2?
The V5C is the original registration certificate. A V5C/2 is a replacement issued when the original is lost, stolen or damaged. Both carry the same information, but the replacement should be accompanied by a DVLA receipt.
If the V5C shows a different keeper than the seller, should I walk away?
Yes. A mismatch suggests the seller is not the registered keeper, which could mean the car is stolen, has outstanding finance, or is being sold without the proper authority. Insist on a correct V5C before proceeding.
