This guide walks you through the essential steps to transfer ownership and update car tax, protecting both you and the buyer.
Understanding the V5C logbook: your essential document
The V5C (often referred to as the logbook) is the official record of the car’s registered keeper. To complete a sale, this document must be used to notify the DVLA of the change.
Who can transfer the vehicle:
- Only the registered keeper listed on the V5C can notify the DVLA of a sale.
- If you are not the registered keeper, you cannot legally transfer the vehicle.
Check your details first:
- Make sure the name and address on your V5C are up to date before the sale.
Keep it safe:
- Never share photos of your full V5C or the 11-digit reference number online.
- Doing so could put you at risk of vehicle cloning.
V5C Logbook – Key Differences (Old vs New)
In the UK, V5C logbooks come in two formats: old and new. Both are valid for transferring vehicle ownership, so you don’t need to replace an older logbook just to make a sale. The main difference lies in the section numbers and labels, which vary between versions, so following the correct instructions for your logbook ensures a smooth, accurate transfer.
| Feature | Old‑Style V5C | New‑Style V5C |
| When Introduced | Around 2004 – the older green/blue format still in use. | First introduced in 2012, with the current redesigned version issued from 15 April 2019. |
| Transfer Section (Postal) | Section 6 – “New keeper details.” | Section 2 – “Selling or transferring my vehicle to a new keeper.” |
| Slip Buyer Keeps | Section 10 – tear‑off “new keeper supplement” (sometimes also referred to as V5C/2). | Section 6 – green “new keeper” slip called V5C/2. |
| Signature (Postal) | Both seller and buyer sign a declaration. | Only the seller signs the declaration – the buyer’s signature isn’t required on the main form itself. |
| Still Valid? | Yes – still accepted by the DVLA for transfers. | Yes – the current format for all V5Cs issued since 2019. |

Transfer ownership online (the fastest way)
The quickest way to notify the DVLA is through the official gov.uk portal. The online form itself is very quick: most sellers can complete it in 5-10 minutes.
What you need:
- The 11-digit reference number from your V5C
- The buyer’s full name and address
Instant confirmation:
- Once submitted, you’ll receive an immediate email confirmation.
- If you provide the buyer’s email (which we recommend), they’ll also receive a receipt.
What to do with the old V5C:
- After receiving online confirmation, destroy your old V5C logbook.
- Do not give it to the buyer as it’s no longer valid.
New logbook:
- The buyer will receive their new V5C by post within 3–5 working days.
The handover:
- Even when transferring ownership online, you must complete the green “new keeper” slip. This is section 10 in the old V5C logbook and section 6 in the new V5C logbook. This is often referred to as V5C/2.
- Fill in the buyer’s name, address, and the date of sale, then tear it off and give it to them.
Transfer ownership by post
If you prefer to transfer ownership by post, then follow these steps:
New-style V5C forms:
- Complete section 2 – “Selling or transferring my vehicle to a new keeper.”
- Complete the green “new keeper” slip (section 6) and give it to the buyer.
- Mail the completed V5C to the DVLA
Old-style V5C forms:
- Complete section 6 – “New keeper details.”
- Both seller and buyer sign section 8 (declaration).
- Complete the green “new keeper” slip (section 10) and give it to the buyer..
- Mail the completed V5C to the DVLA, Swansea, SA99 1BA.
What happens next:
- The buyer (new keeper) will receive their updated V5C within four weeks.
Provide the “New Keeper” slip
Regardless of whether you notify the DVLA online or by post, you must give the buyer the green V5C/2 slip (the “new keeper” section).
The buyer needs this slip to:
- Act as temporary proof of ownership.
- Tax the car immediately before driving it away.
Updating vehicle tax
In the UK, road tax no longer stays with the car when it’s sold.
- For the Seller: As soon as the DVLA is notified of the sale, your tax is automatically cancelled. You will receive a refund for any full remaining months of tax, which is sent to the address on your V5C.
- For the Buyer: The buyer must tax the vehicle in their own name before driving it home. They can do this online using the 12-digit reference number on the green “new keeper” slip.
Create a bill of sale
For added protection, it’s a smart idea to print two copies of a basic receipt (a “bill of sale”). Both parties should sign and date these, including the agreed price, the car’s registration, and the phrase “sold as seen” for private transactions.
What to do if you don’t have the V5C logbook
The quickest and most straightforward solution is to apply for a replacement V5C before you sell.
- You can apply online if you’re the registered keeper and your details are up to date – the DVLA usually posts the new V5C within 5-7 working days.
- If you can’t apply online, use the V62 form (application for a replacement V5C) and post it to DVLA. This takes around 4-6 weeks.
- Once you have the replacement logbook, proceed with the normal online or postal transfer (including detaching the new keeper slip).
Why this helps: Replacing the V5C first (and then transferring it) makes the sale smoother for both you and the buyer and avoids extra paperwork later.
Don’t Forget – It’s The Law
When you sell a car, you must tell the DVLA you’ve sold it – it’s a legal requirement under UK vehicle registration rules.
What can happen if you don’t tell DVLA:
- You could receive a £55 penalty notice, reduced to £35 if paid within 17 days.
- If you ignore the penalty, the case can be taken to court, and you could be fined up to £1,000.
- Until DVLA’s records are updated, you may remain legally responsible for the vehicle – including any fines or penalties incurred by the buyer.
Summary Checklist for Sellers:
- Confirm buyer’s full name and UK address.
- Complete the transfer online or by post.
- Hand over the green V5C/2 “new keeper” slip.
- Provide all sets of keys and service history.
- Remind the buyer they must tax the car before driving.
- Keep a signed receipt for your own records.
By following these steps, you protect yourself and the buyer, ensure the DVLA records are updated correctly, and make the transition smooth, legal, and stress-free – allowing you to move on to your next vehicle with confidence.
