Selling a car in the UK involves more than just handing over the keys. To ensure a smooth and legal transaction, you need the right paperwork to transfer ownership correctly and avoid future liabilities. Missing documents can lead to delays or complications with the DVLA, putting both the seller and buyer at risk. 

Additionally, factors such as outstanding finance, personalised plates, and vehicle tax rules can affect the sale process. Selling a car also involves navigating regional regulations, emission standards, and safety considerations. Understanding these requirements will help ensure you complete the sale efficiently, avoid penalties, and secure the best deal possible.

1. Vehicle Log Book (V5C) – The Most Important Document

The V5C registration certificate, commonly referred to as the log book, is the primary document needed to sell a car in the UK. It records the registered keeper of the vehicle and is issued by the Driver and Vehicle Licensing Agency (DVLA). Without a valid V5C, transferring ownership becomes complicated, and buyers may hesitate to complete the purchase.

What is the V5C Log Book?

• The V5C confirms vehicle ownership and provides important details such as the registration number, make, model, and current keeper’s information.
• It is not proof of legal ownership, but it is essential for notifying the DVLA when a car is sold or transferred.
• If you have lost your V5C, you can apply for a replacement through the DVLA for a £25 fee before selling your vehicle.
• If the car has had multiple owners, the V5C will list previous registered keepers, which may influence the vehicle’s resale value.

How to Transfer the V5C to the Buyer

• If selling privately, complete Section 6 of the V5C and provide the buyer with the green “new keeper” slip.
• If selling to a dealership, fill out the motor trade section.
• Notify the DVLA online (gov.uk) or via post to confirm the sale.
• Ensure all details are accurate to avoid any post-sale disputes.
• If the car is being exported, additional documentation may be required, including customs declarations and export permits.

2. Proof of Sale – Protecting Both Parties

A bill of sale or receipt is highly recommended to provide written proof of the transaction. This ensures both the seller and buyer have a record of the agreement and can prevent disputes. Many private sellers overlook this step, which can lead to complications if the buyer later raises issues regarding the vehicle’s condition or ownership.

What Should the Bill of Sale Include?

• Vehicle details (make, model, registration number, mileage, and VIN)
• Buyer and seller details (names, addresses, and contact information)
• Sale price and payment method
• Date and time of transaction
• Signatures of both parties
• Any agreed terms, such as “sold as seen” if the seller does not provide a warranty

A signed document protects against any future claims regarding ownership or disputes over the sale conditions. It can be particularly useful if a buyer tries to claim they never purchased the vehicle.

3. Valid MOT Certificate – Proving Roadworthiness

An MOT test is a legal requirement for vehicles older than three years in the UK. While not necessary for a sale, having an MOT certificate is essential for a buyer to legally drive the car.

• If the car has a valid MOT, provide the latest certificate to the buyer.
• If the car does not have a valid MOT, the buyer will need to arrange for a new MOT before driving it.
• If the car is sold without an MOT, inform the buyer that they may need to transport the vehicle on a trailer or apply for a temporary MOT exemption.
• Buyers may negotiate a lower price if the vehicle does not have a valid MOT.
• Selling a car without an MOT may reduce its market appeal, particularly for buyers who need an immediately roadworthy vehicle.

4. Service History & Maintenance Records

While not legally required, a full-service history enhances the vehicle’s value and reassures the buyer about its condition. A well-documented service history can make a car more attractive to potential buyers and help justify a higher asking price.

• Include receipts for repairs, oil changes, and part replacements.
• If the car was serviced at an authorised dealership, provide stamped records.
• Mention any outstanding recalls or recent repairs to give full transparency.
• Some buyers may be willing to pay more for a car with a well-documented service history.
• A digital service history from manufacturers like BMW, Mercedes, or Ford can also be shared with the buyer to confirm proper maintenance.

5. Vehicle Tax – What Happens When You Sell?

Vehicle tax is non-transferable in the UK. Sellers must inform the DVLA of the sale to cancel their tax, and buyers must tax the vehicle before driving it.

• Seller: Once the DVLA receives notification, they will automatically cancel the tax and issue a refund for unused full months.
• Buyer: Must tax the car before taking it on the road via the DVLA website or Post Office.
• If the buyer fails to tax the vehicle immediately, they risk fines and penalties.
• Driving an untaxed vehicle is illegal and may result in enforcement action from the DVLA or police.

6. Personalised Number Plates – What to Do?

If the car has private number plates, sellers need to take extra steps before completing the sale.

• Apply to remove the plate via DVLA online or by submitting a V317 form.
• Wait for confirmation from the DVLA before selling the vehicle.
• If the buyer wants to retain the private plate, they must apply for a plate transfer separately.
• Selling a car with a private plate without informing the DVLA could result in losing the right to use that plate in the future.

Selling to a Dealership or Motor Trader – Different Requirements

Selling to a dealership or a registered motor trader follows a slightly different process.

• Fill out the “sell, transfer or part-exchange to the motor trade” section of the V5C.
• Provide the trader’s name and business details.
• Notify the DVLA online to confirm the transaction.
• Keep a copy of any sale invoice for your records.
• If the dealership is offering a part-exchange, ensure you receive documentation confirming the valuation of your car and the terms of the exchange.

Conclusion

Having the correct paperwork is crucial when selling a car in the UK. Ensuring all documents are correctly filled out and submitted protects both the buyer and seller from legal and financial risks. Whether you’re selling to a private buyer or a dealer, following these steps ensures a smooth and hassle-free transaction. 

If in doubt, always check the DVLA website or consult a trusted automotive expert. A well-documented sale not only ensures compliance but also protects you from potential legal issues after the vehicle has left your possession.
