What Paperwork Do You Need When Selling a Car?

Why Paperwork Is Important When Selling

Selling a car is a legal transaction. The paperwork you provide — and the steps you complete — protect both you and the buyer. Getting it wrong can leave you liable for fines, parking tickets, speeding penalties, congestion charges, and even criminal offences committed in a vehicle that is still registered in your name.

Proper documentation also makes the sale smoother and builds trust. A buyer who sees a neat folder of service records, a valid MOT, and a correctly completed V5C is far more likely to proceed with confidence — and far less likely to negotiate aggressively on price.

This guide covers every document you need, how to handle each one, and what to do if anything is missing.

Essential Documents

These are the documents you must have (or should have) when selling a car:

V5C Logbook (Vehicle Registration Certificate)

The V5C is the most important document in any car sale. It is the red/maroon registration certificate issued by the DVLA that records the vehicle's details and the registered keeper's information.

What it contains:

• Vehicle registration number
• VIN (Vehicle Identification Number)
• Make, model, colour, engine size, fuel type
• Date of first registration and year of manufacture
• Registered keeper's name and address
• Number of previous keepers
• V5C serial number and date of issue

Why it matters:

The V5C is how the DVLA tracks who is responsible for a vehicle. When you sell the car, you must transfer the V5C to the new keeper — otherwise, you remain the registered keeper and are liable for anything that happens with the vehicle.

Important note: The V5C is not proof of ownership. It states this clearly on the document. It shows the registered keeper — the person responsible for the vehicle — not necessarily the legal owner. Under a finance agreement, the lender may be the legal owner even though the keeper's name is on the V5C.

Service History

The service history is a record of all maintenance and servicing carried out on the car. It typically consists of:

• Stamped service book — the booklet provided with the car when new, with each service entry stamped and dated by the garage that performed it
• Invoices and receipts — for any work carried out outside the service book, including independent garages, tyre fitters, brake specialists, etc.
• Online service records — some manufacturers and garages maintain digital service records that can be printed or shared

Why it matters:

A full service history (FSH) demonstrates that the car has been properly maintained. It is one of the strongest trust signals in a private sale and can add hundreds — even thousands — of pounds to the sale price compared to a car with no history.

Even partial service history (PSH) is better than nothing. Gather everything you have: garage receipts, parts invoices, booking confirmations, and MOT advisory sheets that show work was recommended and subsequently completed.

MOT Certificate

The MOT (Ministry of Transport) certificate proves that the car has passed its annual roadworthiness test. Cars over 3 years old must have a valid MOT to be driven legally on public roads (with limited exceptions for driving to a pre-booked MOT test).

What to provide:

• The current MOT certificate (paper or digital — the result is stored online by the DVLA)
• Ideally, the full MOT history — available free from GOV.UK by entering the registration number. This shows every test the car has had, including pass/fail results, advisories, and mileage at each test

Why it matters:

A car with a full 12 months of MOT is much more attractive than one with 1–2 months remaining. The MOT history also serves as an independent mileage record — buyers can see the mileage at each annual test and confirm the odometer reading has been consistent.

Receipts for Major Work

Keep and present receipts for any significant work carried out on the car, including:

• Timing belt or chain replacement
• Clutch replacement
• Brake pads and discs
• New tyres
• Battery replacement
• Exhaust or catalytic converter work
• Suspension components
• Any body repairs or paintwork

These receipts prove the work was done, show who did it, and give the buyer confidence that known maintenance items have been addressed. They are especially valuable for high-cost items like timing belts — a buyer seeing a receipt for a recent timing belt change can factor that into their valuation.

Optional but Helpful Documents

These are not strictly required but add value and trust to the sale:

Original Owner's Manual and Handbook Pack

The handbook pack — typically a wallet or folder containing the owner's manual, audio guide, quick-start guide, and warranty booklet — is a nice touch. Buyers appreciate having it, and its absence can raise minor questions about the car's provenance.

If you have lost the handbook, replacement packs can sometimes be found cheaply on eBay or from the manufacturer.

Spare Keys

Handing over both sets of keys (main key and spare) is expected. A missing spare key reduces the car's value — replacement keys with programming can cost £100–£400 depending on the car.

If you only have one key, be upfront about it in the advert. Some buyers will factor the cost of a replacement into their offer, but at least they will not be surprised at the viewing.

Warranty Documents

If the car is still covered by the manufacturer's warranty or an extended warranty, provide the documentation. Active warranty coverage is a strong selling point and can justify a higher price.

Even if the warranty has expired, the original warranty booklet shows the buyer what was covered and for how long.

Vehicle Check Report

Running a vehicle history check on your own car before selling it — and sharing the results with buyers — is an increasingly common and effective trust-building tactic.

A Check A Car report confirms:

• No outstanding finance recorded against the vehicle
• Not reported stolen
• No write-off or insurance claim markers
• Mileage verification across historical records
• VIN and registration match

Sharing this report proactively removes common buyer objections and positions you as a transparent, trustworthy seller.

How to Fill Out the V5C Correctly

Completing the V5C transfer is the most critical administrative step in selling a car. Getting it wrong causes problems for both you and the buyer.

Section 6: New Keeper Details

When you sell the car, fill in Section 6 of the V5C with the new keeper's details:

• Full name of the buyer
• Address of the buyer

Write clearly and use the buyer's details exactly as they want them registered with the DVLA.

The Green Slip (V5C/2 — New Keeper Supplement)

Once Section 6 is completed:

1. Tear off the green V5C/2 slip from the bottom of the V5C
2. Give the green slip to the buyer — this is their temporary proof of the transaction until they receive a new V5C in their name (usually 2–4 weeks)
3. Keep the rest of the V5C — you will either post it to the DVLA or use the details to notify them online

Section 8: Declaration by the Registered Keeper

Complete Section 8 to formally declare that you are no longer the keeper of the vehicle. Sign and date it.

Sending the V5C to the DVLA

You have two options:

Option 1: Notify online (recommended)

• Visit GOV.UK and use the "Tell DVLA you've sold a vehicle" service
• You will need the 11-digit reference number from the V5C
• This is instant — you receive immediate confirmation that the DVLA has been notified
• The remaining V5C can then be destroyed

Option 2: Post the V5C

• Send the completed V5C to the DVLA at the address printed on the form
• This takes longer — allow several working days for delivery and processing
• Consider sending by recorded delivery for proof of posting

Always notify the DVLA on the day of sale. Until you do, you remain the registered keeper and are liable for any fines, penalties or offences associated with the vehicle.

Notifying DVLA of the Sale

Notifying the DVLA is not optional — it is essential. Here is why:

What Happens If You Do Not Notify

If you fail to tell the DVLA you have sold the car:

• Speeding fines addressed to the registered keeper will come to you
• Parking tickets from councils and private operators will be sent to your address
• Congestion charges and ULEZ penalties (London) will be charged to you
• Road tax reminders will arrive in your name
• If the car is used in a crime, the police will come to you first

You are legally responsible until the DVLA updates their records. Notifying them immediately upon sale protects you from all of these risks.

How to Notify

Online (fastest and recommended):

1. Go to GOV.UK — "Tell DVLA you've sold a vehicle"
2. Enter the vehicle registration number
3. Enter the V5C reference number (11 digits)
4. Confirm the sale details and the new keeper's information
5. You will receive an on-screen confirmation — save or print this for your records

By post:

1. Complete Sections 6 and 8 of the V5C
2. Post the V5C to: DVLA, Swansea, SA99 1BD
3. Keep a note of when you posted it and consider using recorded delivery

What to Give the Buyer

At the point of sale, the buyer should receive:

• The green V5C/2 slip (new keeper supplement) — their proof of purchase
• Service history — stamped service book, invoices and receipts
• MOT certificate — current certificate or confirmation it is accessible online
• Handbook and owner's manual (if available)
• Both sets of keys (if available)
• Spare wheel and tools (if the car has them)
• Locking wheel nut key — often forgotten but essential
• Any warranty documentation
• Vehicle check report (if you ran one)
• Receipts for recent work

Keeping Proof of Sale

A written receipt protects both parties and provides evidence of the transaction. This is particularly important if disputes arise later.

What to Include in a Receipt

• Date of sale
• Seller's full name and address
• Buyer's full name and address
• Vehicle details: make, model, registration number, VIN, colour, mileage at point of sale
• Agreed sale price (written in both numbers and words to avoid ambiguity)
• Payment method (bank transfer, cash, etc.)
• A statement that the car is sold as seen (for private sales — this does not override statutory rights if selling as a trader, but is standard practice between private individuals)
• Signatures of both buyer and seller

Keep Copies

• The seller should keep one copy
• The buyer should keep one copy
• Store your copy alongside the DVLA notification confirmation — together, these documents prove you sold the car, when, to whom, and that you notified the DVLA

What to Do If Paperwork Is Missing

V5C Is Lost

If you do not have the V5C:

1. Apply for a replacement from the DVLA — this costs £25 and takes approximately 5 working days
2. Do not sell the car without it — a missing V5C is a major red flag for buyers and makes the transfer process much more complicated
3. While waiting for the replacement, you can still prepare and advertise the car — just note in the advert that the V5C is being replaced

Service History Is Missing

If you have lost the service book:

• Contact previous garages — many garages keep digital records and can provide printouts or duplicate stamps
• Gather any invoices, receipts, or email confirmations of work done
• Print the MOT history from GOV.UK — this provides an independent record of mileage and any advisories that were subsequently fixed
• Be honest in the advert — state "partial service history" or "service history lost, invoices available" rather than claiming full history you cannot prove

MOT Certificate Is Missing

• MOT results are stored digitally. The buyer can check the MOT status online using the registration number at GOV.UK
• If the car needs a new MOT, consider getting one before selling — a fresh MOT is a strong selling point

Keys Are Missing

• If the spare key is lost, mention this in the advert so the buyer is not surprised
• The buyer may want to factor the cost of a replacement key into their offer (£100–£400 depending on the car)
• For security, if you have lost a key, consider having the remaining key reprogrammed so the lost one cannot be used

Final Paperwork Checklist Before Handover

Run through this checklist before handing the car over:

• V5C Section 6 completed with the buyer's name and address
• Green V5C/2 slip given to the buyer
• DVLA notified of the sale (online confirmation saved)
• Receipt of sale written and signed by both parties — both keep a copy
• Service history and MOT documents handed over
• Handbook, spare keys, locking wheel nut key included
• Payment confirmed in your bank account (not just a screenshot)
• Insurance company notified that you have sold the car
• Road tax — will be automatically cancelled by the DVLA when the keeper change is processed. Any remaining full months will be refunded
• Remove the car from toll accounts — Dart Charge, congestion charge, ULEZ, or any other automatic payment systems linked to the registration

With all paperwork completed correctly, you have a clean legal break from the vehicle. The buyer has everything they need to register, insure and enjoy their new car — and you have the documentation to prove the sale if any issues arise in the future.
