What documents do I need to sell my car in the UK?
Whether you are selling your car privately, part-exchanging it at a dealership, or selling it to an online buying service, having the right documentation in order before the sale makes the process smoother, protects you legally, and helps you achieve the best possible price. Missing or incorrect paperwork is one of the most common reasons car sales fall through or attract lower offers.
This guide covers every document you are likely to need, explains what each one does, what to do if you have lost any of them, and how to transfer ownership correctly once the sale is complete.
The V5C logbook: the most important document
The V5C registration certificate — commonly called the logbook — is the single most important document in any car sale. It is issued by the DVLA and records the registered keeper of the vehicle, the vehicle identification number (VIN), engine number, colour, and technical specifications. It is not proof of ownership in a legal sense — it records the registered keeper, not the legal owner — but in practice it is the primary document buyers and dealers use to verify that the person selling a car has the right to do so.
Without a V5C, selling your car is significantly harder. Most dealers and online buying services will reduce their offer or decline to buy a car without one. Private buyers are strongly advised never to buy a car without seeing the original V5C, and a responsible seller should always be able to produce it.
The V5C contains a yellow section (section 6 in older documents, or a yellow ‘sell, transfer or part-exchange your vehicle to a motor trader’ slip in newer ones) which the buyer needs when notifying the DVLA of the change of keeper. Keep the green ‘new keeper supplement’ section (V5C/2) separate — this is what a private buyer uses to tax the vehicle immediately while waiting for their new V5C to arrive from the DVLA.
What to do if you have lost the V5C
If you cannot find your V5C, you need to apply for a replacement before selling. You can apply online via the GOV.UK website or by post using form V62. The replacement fee is £25. DVLA typically issues a replacement within five working days when applied for online. Do not attempt to sell a car using a V5C that does not show you as the registered keeper — update it first if your details have changed.
Be cautious of buyers who say a missing V5C is not a problem — this is a known tactic in car fraud, where criminals try to buy cars cheaply using the absence of the logbook as leverage, or where the car itself may have a problematic history that the buyer knows about. A legitimate buyer will always wait for the correct paperwork.
The MOT certificate
A valid MOT certificate confirms that the car met the minimum roadworthiness standards at the time of the test. Buyers and dealers will check the MOT status and history on the GOV.UK MOT history tool, which is publicly accessible using the registration number. This tool shows the date and result of every MOT, the mileage recorded, and any advisories or failure points.
Having a current MOT — particularly one with several months remaining — adds value to the car, as the buyer does not face an immediate re-test cost. A car with an expired MOT can still be sold, but it cannot be driven on the road by the buyer until a new MOT has been passed (other than to a pre-booked MOT appointment). Many buyers will factor the cost and inconvenience of an imminent MOT into their offer.
The physical MOT certificate is less critical than it used to be, since the DVLA holds digital records. However, having a complete file of physical MOT certificates provides additional confirmation of the car’s mileage history and is worth presenting if you have kept them.
Service history records
Service history is not a legal requirement for selling a car, but it has a significant effect on value and buyer confidence. A full service history — a stamped service booklet or documented service records at every recommended interval — demonstrates that the car has been maintained correctly and gives buyers confidence in its mechanical condition.
Gather everything you have: the manufacturer’s service booklet with dealer stamps, any receipts from independent garage services, and any receipts for work done such as cambelt changes, brake replacements, or tyre replacements. If the car has been serviced at a main dealer with electronic records, check whether you can download or print the service record from the manufacturer’s customer portal before the sale.
Even a partial service history — some records but not all — is better than presenting nothing. Present what you have clearly and honestly, rather than hoping the gap goes unnoticed. Buyers and dealers will assess the records carefully.
Finance settlement documentation
If your car is subject to an outstanding finance agreement — PCP or HP — you cannot legally sell it without settling the finance first, because the finance company legally owns the vehicle until the final payment is made. Selling a financed vehicle without the lender’s knowledge or without settling the agreement is potentially fraudulent.
Before selling, contact your finance company and request a settlement figure. This is the amount required to pay off the agreement in full. They are required to provide this within seven working days under the Consumer Credit Act 1974. The settlement figure will be valid for a specific period — typically 10 to 28 days — and should be requested as close to the sale date as practical.
If you are selling to a dealer or part-exchanging, the dealer will typically handle the settlement directly with your finance company as part of the transaction. Ask the dealer to confirm this in writing before proceeding. If you are selling privately, you will need to settle the finance yourself before transferring the car to the buyer, or arrange for the buyer to pay the settlement directly to the finance company and pay you any remaining equity separately.
Any buyer or dealer you deal with should run an HPI check on the car before purchase. This check reveals whether there is outstanding finance registered against the vehicle. A buyer who purchases a car with outstanding finance in good faith can have the car repossessed by the finance company — which is why responsible buyers always check, and why sellers should be transparent about any outstanding agreement.
The car’s keys and spare keys
While not a document, both sets of keys — or all sets if there are more than two — should be present for the sale. A missing spare key is a legitimate deduction in a dealer’s offer, since replacement keys for modern cars with electronic fobs can cost £150–£400 or more from a main dealer. If you have lost a spare key, disclose this upfront rather than hoping it is overlooked.
Additional documents that add value
The following documents are not legally required but make a material difference to buyer confidence and achieved price: the original purchase invoice or order form (confirms when the car was first registered and at what specification), manufacturer warranty documentation and any remaining warranty (if the car is still within the original warranty period), recall completion letters (if the car has been subject to a manufacturer recall, evidence that the work was carried out is reassuring to buyers), road tax information (road tax is no longer transferable between keepers and is automatically cancelled when the car changes hands — the seller receives a refund for any unused complete months, and the buyer must tax the vehicle before driving it).
How to transfer ownership correctly
When you sell your car, you must notify the DVLA that you are no longer the registered keeper. Failure to do so means you remain on the DVLA’s records as the keeper — which could result in you receiving penalty charge notices, fines, or other correspondence relating to the car after the sale.
The process depends on whether you are selling to a private buyer or to a dealer. When selling to a private buyer, complete the new keeper section of the V5C (the green V5C/2 slip) and give it to the buyer. Keep the main V5C document and send the relevant section to the DVLA — or, more easily, use the GOV.UK ‘Tell DVLA you’ve sold a vehicle’ service online. You will receive a confirmation and any road tax refund within four to six weeks. When selling to a dealer or trade buyer, the dealer handles the DVLA notification. Give the yellow section of the V5C to the dealer and keep the main document to send to DVLA yourself, or follow the dealer’s specific instructions — they will advise on their process.
Do not give the entire V5C to a buyer and assume they will notify the DVLA. This is a common mistake that leaves you legally exposed if the buyer does not register the change promptly.
Cancelling your insurance
Once the car has been sold and ownership transferred, contact your insurer to cancel your policy. Do not cancel before the sale is complete — you need the car to remain insured until the point of handover. Most insurers will provide a pro-rata refund for any unused portion of your policy, minus a cancellation fee. Check your policy’s cancellation terms before the sale so you know what to expect.
If you are part-exchanging and driving away in a new car the same day, check that your new car is insured before you leave the forecourt — do not assume your existing policy automatically covers a replacement vehicle.
Quick-reference document checklist
The following summarises what to have ready before selling your car. V5C logbook: essential for all sales — apply for a replacement if lost (£25, GOV.UK). MOT certificate: physical copy helpful, digital records are held by DVLA. Service history: stamped booklet and any receipts — present everything you have. Finance settlement letter: required if the car has outstanding finance — obtain from your finance company before sale. All keys: both sets including spare if available — missing keys will reduce the offer. Purchase invoice: optional but adds buyer confidence. Warranty documentation: if still within manufacturer warranty period.
