Handing Over the New Keeper Slip
As long as the buyer of your car is in the UK and not taking the vehicle abroad, you need to give them the green ‘new keeper’ slip from your logbook (V5C).
This little slip then proves that they are the new owner and allows them to register the car in their name with the DVLA as a direct result.
What if You've Lost Your V5C?
If you have lost your V5C, then do not panic.
For instance, you can order a replacement from the Vehicle Licensing Agency.
To do this, you fill in a V62 form or request it online, and there is a small fee to do so. But it is a good idea to get it sorted before looking to sell your car.
Service History and Maintenance Records
A full-service history then gives prospective buyers peace of mind that the car they are about to get has been well kept and repair bills should be at a minimum, at face value, thus reducing their risk.
It also shows that the car has been well cared for, and that can then help you get a better car valuation as a result.
Here, even a partial history is better than nothing; we should note it.
What are Classed as Service and Maintenance Records?
Documents here that are classed as Service and Maintenance Records include, for instance:
- Stamped service book from an authorised garage
- Receipts for routine services (e.g., oil changes, filter replacements)
- Invoices for repairs and parts (e.g., brake pads, tyres, clutch)
- MOT test certificates
- Receipts for major work (e.g., timing belt replacement, engine repairs)
- Air conditioning servicing records
- Battery replacement invoice
- Tyre fitting and alignment receipts
- Documentation for any recalls or warranty repairs
- Record of diagnostic checks or software updates
How to Organise and Present Your Service Records?
When it comes to presenting these, here you want to gather all your documents, including MOT tests, car repair receipts, and car parts invoices that you have.
Then, you want to put them in date order and use a folder or envelope, as this will make it easy for the prospective buyer to see them quickly and what has been done so far.
MOT Certificate and History
Your car then must have a valid MOT if it’s over three years old.
For instance, here, you want to make sure to have the latest MOT certificate on hand.
Car buyers then often check the DVLA website for your MOT history to see if the car’s had any major issues - so having this to hand is really helpful ahead of time.
How to Checking MOT Status Online
Head over to GOV.UK and enter your number plate, which is very quick and reassures buyers that everything is on board.
Receipts and Invoices for Repairs or Modifications
If you have done any work on the car – new tyres, brake pads, engine fixes – you ideally want to keep all those parts receipts and invoices.
These receipts then help, because they help you to build trust and show that the car has been looked after and how.
Proof of Purchase and Ownership
A simple bill of sale can help.
This bill of sale, then, would include details like the vehicle details, date of sale, names and signatures of both parties and the selling price, as this acts as proof of purchase while helping to resolve any future disputes from occurring.
Although not legally required, issuing clear and properly worded receipts during the car selling process is really considered best practice — and it's something buyers often expect and someone like us will do.
However, presenting the bill of sale from when you originally bought the car will also help you get the best prices.
Presenting this, for instance, gives you a well-documented transaction that protects both parties, avoids misunderstandings, and serves as strong evidence in case of disputes later on, which helps us know the car's history in more detail.
Reservation or Holding Deposit Receipts
In car sales, it’s common for a buyer to pay a small deposit to reserve the car while they arrange the full payment or financing.
A reservation receipt then documents the fact that this agreement occurred.
This receipt should include, for example:
- Full names and contact details of buyer and seller
- Date the deposit was received
- Amount paid and outstanding balance
- Vehicle details (make, model, registration, VIN)
- Agreed sale price and any conditions (e.g., “subject to inspection/test drive”)
- Deadline for completing the sale
- Signature from both parties
Final Sale Receipts (Bill of Sale)
Once the full payment was made prior you should have attained a bill of sale when the car was handed over to you - also known as a final receipt.
This document then acts as proof of purchase and shows that you are the new legal owner.
This receipt should show:
- Full names and addresses of both buyer and seller
- Car details: make, model, year, registration number, VIN
- Date and time of sale
- Total price paid and confirmation that payment was received
- Statement confirming the vehicle was sold “as seen and inspected” unless otherwise agreed
- Signatures of both parties
Make Two Copies
When you get your bill of sale, you should always prepare two signed copies of each receipt — one for you and one for the buyer.
This helps avoid any future confusion about the terms of sale or who owns what, and here it is the one you received that you want to make sure you include.
Digital Receipts and E-Signatures
It is also common today that you may have this in a digital form.
As a result, you should be able to provide the digital receipt or agreement.
Road Tax Considerations
One thing many people miss is that when you sell a car, the vehicle tax does not just go with it - the new owner must tax it themselves, and you can get a refund on unused road tax as well.
Road Tax Refund Process
Usually, once the sale is processed and registered, you will automatically get a refund for any full months left on your tax once you inform DVLA. However, if this does not occur, you will then have to contact the DVLA to see what has happened
Car Manual and Spare Keys
While it’s not legally required, the car owner’s manual and spare keys tend to be far from optional.
These are far from optional, as they are practical and reassuring documents for the buyer — and including both of them shows that you have taken care of the car.
This small book can have a big impact on buyer confidence and could even help you indirectly get the best price for the car.
So, Why Does the Owner’s Manual Matter?
Handing over the manual adds value because it helps the new owner do several things:
- Understand dashboard warning lights and what to do about them
- Locate things like fluid reservoirs and fuse boxes
- Lists off the car specifications and gives the buyer easy troubleshooting tips
- Check and maintain correct tyre pressures
- Troubleshoot minor issues without calling a mechanic
- Follow the correct maintenance schedule to keep the car running smoothly
Of which, all of this supports a smoother ownership experience and shows that the car has been well looked after — making your sale more appealing and trustworthy overall.
What If the Manual Is Missing?
If you have misplaced the original handbook, do not worry — as there are a few ways to get a replacement, which can include, for instance:
- Check the manufacturer’s website using your vehicle’s VIN number — as many brands like Ford, Toyota, and Nissan offer free PDF downloads
- Contact a dealership — some can even order you a printed replacement
- Look on car owner forums or online marketplaces like eBay for second-hand manuals
Digital vs Physical Manuals
Digital manuals are more convenient and often free, but many buyers still appreciate having a physical copy in the glovebox.
They do so as it feels more complete and professional, especially for buyers who are not as tech-savvy or who like having quick access to information while on the road.
If You Can’t Find Your Owner’s Manual
If you are unable to locate it, here are some to try:
- Search your home or glovebox thoroughly – it’s often misplaced rather than lost
- Visit your car brand’s official website to download a digital copy
- Contact the local dealership for a printed replacement
- Check if previous servicing garages might have one on file
- Include a digital version link in your advert if a physical copy isn’t available
Pro Tip
Adding the owner’s manual might seem like a small detail, but it sends a strong message that this car has been cared for - which is what will help to determine the price you get.
It’s a simple and inexpensive way to add value and reassure the buyer due to this.
Insurance Documentation
As soon as the sale is complete, you will need to cancel your insurance policy.
Here, you need to let your provider know and do not forget to remove the car from your car insurance, too.
What if the Car Has Been in an Accident or Repaired?
If your car has been involved in an accident and professionally repaired, then you should not shy away from sharing this - as this is normally evident for buyers to find out for themselves.
As a result, providing documentation for any insurance claims, including repair invoices or assessments, can also reassure potential buyers that everything was handled properly and the car is safe and roadworthy now.
Buyers appreciate honesty, and being upfront about past damage — along with evidence of quality repairs going into rectify this — can build trust and actually improve your chances of selling it for a higher value as well, as they then have more confidence that issues from it will not occur due to it being correctly fixed.
Disclosing Insurance-Related Repair History
Even if repairs were minor, it is a good idea to disclose them.
As failing to do so could cause disputes later on if the buyer finds out as this could be classed as misrepresentation or even fraud from your side.
Full transparency here also shows that you are a trustworthy seller and helps to avoid any awkward conversations down the line.
Post-Sale, What to Do With Insurance and Finance
Once the sale is done, here’s what you need to do next:
For Insurance
- Inform your insurer the car has been sold
- Cancel your policy or transfer it to your new car
- Check for any cancellation fees or refund eligibility
For Finance
- Use the settlement letter to pay off any remaining balance
- Confirm the account is fully closed
- Keep confirmation emails or letters from your finance company for your records
Selling to a Dealer vs Private Buyer - What Are the Documentation Differences?
Here, a dealer or motor trader often handles most of the paperwork for you - like we will.
However, one thing to look for if you are going to a private seller is that this is then all on you to complete correctly - so you need to make sure that you double-check everything so your private sale is above board and that you do not get stung.

Digital vs Paper Documentation
Providing digital documents is usually fine these days, but physical copies still matter a lot, so it is ideal to have both.
Things such as your photo ID, proof of address (like a bank statement), and even a bank account number for bank transfer are also beneficial things to have.
Do I need a driving licence to sell my car?
It is not a legal requirement to have your driver's licence to sell your car, but having your licence as a photo ID will help confirm your identity with car buyers quickly to make sure that you are the genuine keeper of the car.
What if there’s outstanding finance?
Any outstanding finances will need to be cleared before selling the vehicle.
As with outstanding finance, you do not actually own the car to be able to sell it in this situation - the finance company still does.
If you are unsure, then check with your finance company, as selling with outstanding finance without disclosing it is illegal and can get you in a lot of trouble.
What Is a Finance Settlement Letter and Why You Need One
If your car is still under finance, you cannot legally sell it without clearing the balance.
To do that, you’ll need a finance settlement letter from your finance company, as this letter:
- Details the outstanding balance you still owe
- Includes payment instructions and a deadline
- May be required by a dealership or buyer before the sale
This letter will then prove to everyone involved that you are handling the outstanding finance properly outside of the transfer of the vehicle - making it an essential part of a legal and transparent sale.
Be Transparent About Insurance and Finance Status
It is also illegal to sell a car with outstanding finance without informing the buyer.
As a result, hiding this can lead to serious legal trouble, so you should always disclose the car’s financial status and provide relevant documents when required.
Likewise, if the car has had insurance repairs, sharing that info upfront gives buyers confidence and reduces the risk of the sale falling through.
Insurance and Finance Checklist for Sellers
Here’s a quick summary of what you will tend to need here:
- Insurance policy number and provider details
- Documentation for any past insurance claims (if applicable)
- Finance settlement letter (if the car is still under finance)
- Proof that finance has been paid off before handing over the car
- Confirmation from insurer once the policy is cancelled or transferred
Can buyers take the car for a test drive?
They can, and you should always ask to see that their car insurance covers them to drive other vehicles, and you should also go along for the ride as well.
Can I keep my number plate?
If you want to keep your number plate, especially if it is a private plate, you should make sure that you fill in a Number plate retention form through the DVLA and transfer it to another car or keep it on retention.
Car Warranty Documentation, What You Need to Know When Selling
If your car still has a valid warranty, it is also a great selling point and something you should definitely mention to potential buyers as well.
For instance, did you know that many newer cars - or those bought through dealers - come with manufacturer warranties that can be transferred to the new owner?
Well, when selling a used car, it is helpful to include any paperwork related to the warranty as well, and this can include, for instance:
- Original warranty certificate or documents
- Details of what the warranty covers (e.g., parts, labour, roadside assistance)
- Expiry date of the warranty
- Proof of eligibility, such as full-service history if that’s a condition
However, you want to be clear about whether the warranty is still valid and if it is transferable before you do, as not all are.
Especially if the warranty came through a third-party provider; in this case, you should contact them to check what is needed to transfer it to the new keeper.
Step-by-Step on How to Transfer Your Car Warranty
So you have an active warranty, then here is what you need to do to prepare and transfer it smoothly:
Check if it’s transferable
Not all warranties are transferable. Here, you should look at the terms or contact the provider directly - especially for third-party warranties.
Gather your paperwork
Next up, you need to get all your warranty documents together, including the certificate, terms and conditions, and proof of eligible servicing.
Contact the provider
Now that you have the documentation, you should inform them of the sale and ask about the process for transferring the warranty, as this can differ slightly from provider to provider.
Confirm if there’s a fee
Some warranty transfers can also come with a small charge or require a form to be filled out, which you will need to factor in as well.
Hand over everything to the buyer
Then, once you are happy, include all warranty-related paperwork, and the new buyer will then need to complete the paperwork to transfer this over to them.
Manufacturer vs Third-Party Warranties, What is the Difference?
Understanding the type of warranty you have can save you and your buyer a lot of confusion, and these tend to fall into 2 camps:
Manufacturer Warranties
These are often simpler to transfer – sometimes, it happens automatically with just a proof of service, and they are typically valid for 3–7 years and stay with the car as well - which makes it very easy.
Third-Party Warranties
These might need more paperwork and a formal request sent over to the provider.
There could also be a small fee, and proof of full-service history is often needed to essentially qualify here as well.
Don’t Forget to Highlight It
Most sellers tend to skip this, but mentioning a transferable warranty when selling your car can make a huge difference, and you should mention:
- The length of the remaining warranty
- Whether it’s a manufacturer or third-party warranty
- Any extras like roadside assistance or service plans that come with it
As overall, this then gives your car a stronger value proposition and can help you get a better price as a result of having this in place.
Warranty Transfer Timelines
In most cases, it is best to begin the warranty transfer process as soon as the sale is agreed upon, as some providers have strict deadlines, such as completing the transfer within 7 to 14 days after the sale.
As a result, starting early helps avoid missing out due to delays or simple paperwork issues here.
Exclusions and Limitations
Even the best warranties come with a few strings attached.
For example, common exclusions include wear-and-tear items (like tyres and brake pads), aftermarket modifications, or non-standard parts.
As a result, here, you should be prepared to answer questions about what the warranty actually covers, as not all warranties are the same.
Digital vs. Paper Warranty Records
Many modern warranties are also not in paper form —especially from manufacturers — and are stored online.
As a result, you also need to check ahead of time whether an online account needs to be transferred or updated as part of the sale.
As your buyer will need access to the account to make any future claims, it is important not to forget this step.
How to Replace Lost Warranty Documents
So you have just realised that you have misplaced the original warranty paperwork - well, do not worry.
If you can not find this bit of paperwork, then you should contact the dealership or the warranty provider directly.
They can then usually send a replacement document or a confirmation letter stating the warranty details and whether it is still valid, for example.
What’s the best way to get paid?
A bank transfer is the safest, and you want to avoid any cheques or large amounts of cash for your protection in general. As cheques can be cancelled before payments go over, it is never a good idea to carry large sums of physical cash with you in case you get robbed.
