One of the most persistent misconceptions in used car buying is that the V5C logbook proves who owns a car. It doesn't. The V5C is a registration document — it records who is registered as the keeper, which is not necessarily the same as who owns the vehicle. The legal owner of a car under a hire purchase agreement is the finance company, not the person whose name is on the V5C. The V5C records the keeper; ownership is a separate legal question determined by how the vehicle was acquired and whether any finance is outstanding.
This distinction matters because people regularly use the V5C as a shortcut for ownership verification when it isn't. It's useful but not definitive. What it is definitively useful for is the registration transfer process — completing the change of keeper when a car changes hands, whether by private sale, dealer sale, gift, or inheritance.
This guide covers the full process: how to complete a private sale transfer, what each section of the V5C means, what to do when the V5C isn't present, and the connected questions about road tax that catch buyers out.
What the V5C actually is
The Vehicle Registration Certificate (V5C) is a DVLA document that records the registered keeper of a vehicle, the vehicle's basic specification, and its registration history. It's burgundy red, typically between one and three pages when printed, and is issued by the DVLA to whoever is the registered keeper at the time of issue.
The V5C records: the registration number, make, model, colour, engine size, VIN/chassis number, date of first registration, registered keeper name and address, and brief registration history. It's the core document used to notify the DVLA of a change of keeper, apply for duplicate documents, and — for DVLA purposes — confirm the current registered keeper at any given time.
What it doesn't record: whether the vehicle has outstanding finance, whether it has been stolen, whether it's been in an accident, or whether the registered keeper is the legal owner. For those questions, a vehicle history check is the correct tool.
Transferring ownership in a private sale — the standard process
When a private sale completes, both the seller and buyer have responsibilities to DVLA. The process has been simplified through the online notification system, but the paper route via the V5C remains valid and is how most private sales are completed.
Section 6 — the new keeper supplement. In the current V5C format, the bottom section (sometimes called the "green slip" in older versions, though the colours have changed) is the new keeper supplement. When a private sale completes, the seller completes this section with the sale date and hands it to the buyer. The buyer keeps this as temporary confirmation of the transfer while the new V5C is being processed.
The seller's responsibility. The seller must notify the DVLA that they have sold the vehicle. This can be done online at the DVLA's vehicle management service using the V5C reference number — the quickest method, which notifies DVLA immediately. Alternatively, the seller completes the relevant section of the V5C and posts it to the DVLA address printed on the document. The seller should do this on the day of the sale, not days or weeks later.
This matters for the seller because road tax and any penalties related to the vehicle — including parking fines and camera-detected offences — continue to be associated with the registered keeper until the DVLA processes the transfer. A seller who fails to notify promptly can find themselves receiving correspondence about a car they no longer own.
The buyer's responsibility. The buyer receives the new keeper supplement and waits for a new V5C to arrive from the DVLA, which typically takes two to four weeks. If no V5C arrives within six weeks, the buyer can contact the DVLA. The buyer should also retain any receipts, bank transfer records, or written sale agreements from the transaction as documentary evidence of the purchase.
Buying through a dealer
When buying through a dealer, the transfer process is usually handled by the dealership. The dealer notifies the DVLA, completes the paperwork, and the buyer should receive a new V5C in their name within a few weeks of purchase. If you haven't received a V5C after six weeks from a dealer purchase, contact the dealer first, then the DVLA if the dealer can't resolve it.
What to do if there's no V5C
This is one of the most frequently encountered complications in private used car buying. The current keeper doesn't have the V5C — it was lost, never arrived, or exists somewhere in the house but can't be located. Should you proceed?
A missing V5C on an otherwise clean, well-presented car with a verifiable service history is not automatically a red flag. V5Cs do get lost. What matters is whether the rest of the documentation makes sense — service history, MOT certificates, previous V5C if available, and a seller who can explain when and how the V5C went missing.
What's more concerning: a seller who is vague about when they acquired the car, who can't produce any documentation beyond the car itself, or who seems uncomfortable with questions about the V5C's absence. A genuine owner with nothing to hide can explain a missing V5C clearly.
Proceeding without a V5C is legally possible. A buyer who purchases without the V5C needs to apply for a new one from the DVLA (form V62, available on the DVLA website) after the purchase. The application costs £25 and requires proof of keeper status. It's a manageable process but adds friction that's worth knowing about before you commit to a purchase.
The one scenario where a missing V5C should make you stop entirely: the seller has a V5C but it doesn't match the car. A V5C where the VIN, registration number, colour, or specification doesn't match the physical vehicle in front of you is either evidence of a mistake or evidence of something more serious. Don't proceed until you can account for every discrepancy.
Road tax — it does not transfer with the car
This catches buyers out regularly enough to be worth stating plainly. Road tax is not transferred when a car is sold. The seller's tax is cancelled automatically by the DVLA when the transfer is processed, and the seller receives a refund for any complete months remaining. The buyer must tax the vehicle before driving it on the road — it is illegal to drive an untaxed vehicle except in very specific circumstances.
Taxing a newly purchased car is straightforward: you need the new keeper supplement (the section of the V5C the seller gives you) and a valid MOT. You can tax online using the reference number from the new keeper supplement. The tax starts from the date you apply, so there's no benefit to delaying.
The seller who tells you "there's eight months of tax left on it, it's included in the price" is either confused or misleading you. The tax doesn't transfer. The seller gets a refund for the remaining full months. The buyer pays from the day they take ownership.
Checking the DVLA records before you buy
Before completing any purchase, you can check the basic DVLA record for a vehicle using the registration number via the DVLA vehicle enquiry service. This shows the make, colour, engine size, tax status, and MOT expiry — all publicly available. It confirms whether the car is currently taxed, whether it's SORN, and that the basic specification matches what the seller is claiming.
It doesn't show keeper history or the full ownership record — for that, a full vehicle history check is needed. But the free DVLA check is a sixty-second step that should always precede any viewing.

ULEZ and Clean Air Zone considerations
If you're buying a car for use in London or any city with a Clean Air Zone, check the vehicle's Euro emission standard before completing the transfer. The V5C records the engine specification from which the Euro standard can be determined, and the TfL and relevant local authority websites let you check a registration number against their compliance requirements.
This is worth doing before purchase rather than after, because a non-compliant car in a ULEZ or CAZ zone incurs daily charges that can make a cheap purchase considerably less cheap in practice. Petrol cars registered before September 2006 and diesel cars registered before September 2015 are the categories most likely to be affected. Check before you buy.
After the transfer — what to do next
Once you have the new keeper supplement and have notified the DVLA (or confirmed the dealer has done so), the immediate practical steps: tax the car if it isn't already taxed, arrange insurance before driving (your insurer will need the registration number), and keep all sale documentation in a safe place. The new V5C will arrive within a few weeks — keep it with the car's other documentation.
If you plan to change the registered address — because you've moved, or the car is being registered at a new address — you can update the V5C via the DVLA's online service once the initial transfer is complete.
The whole process, when the paperwork is in order on both sides, takes about ten minutes to initiate and a few weeks for the new V5C to arrive. The complications arise when documentation is missing, mismatched, or — in worst cases — fabricated. The due diligence before the sale is what prevents those complications.
