What the V5C actually is, and why it matters at the point of sale
The V5C is the vehicle registration certificate, proof of who's the registered keeper, not proof of ownership on its own. It records the reg number, make, colour, and the current keeper's name and address. At the point of sale it's the one document that legally moves the car from your name to the buyer's, so getting it right protects both sides.
The three parts that matter when you sell
- <strong>V5C/2, the new keeper supplement.</strong> A green slip at the back of the logbook. Fill it in with the buyer's details and hand it straight to them, they need it to tax the car before driving it away.
- <strong>The main V5C.</strong> Fill in the yellow section with the date of sale and the new keeper's details, then send it to the DVLA, by post or by notifying online, on the day of the sale.
- <strong>Your own record.</strong> Not part of the form itself. Photograph or photocopy the front page before you send it off, since it's no longer yours to reference once it's gone.
Miss the second part and you're still the registered keeper on paper, which matters far more than it sounds.

Why the buyer can't just keep driving on your slip
Road tax has never transferred with the car since 2014. The buyer must tax it themselves, in their own name, before they drive it, using the reference number on the V5C/2 slip. Untaxed driving after that point is their offence, not yours, but the DVLA only shows them as keeper once your part of the V5C has actually been sent off, which is exactly why doing it the same day protects you too.
Notify online or post it, which is actually faster
| Method | Speed | What you need |
|---|---|---|
| Online, via gov.uk | Change registered within minutes, new V5C posted to the buyer in a few weeks | The 11 digit reference number from the V5C, a few details about the sale |
| By post to the DVLA | Can take several weeks to process | The main V5C, correctly filled in, sent by ordinary post |
Online is the better default in nearly every case: it's free, near instant on the DVLA's side, and gives you a confirmation you can screenshot. Keep that confirmation with your own copy of the front page.
What if the V5C is lost, damaged, or still shows an old keeper
- Lost or damaged before a sale: apply for a replacement (a V62 form, a small fee, a couple of weeks to arrive) before listing the car, since a missing logbook puts off serious buyers.
- Bought the car without a V5C update from a previous private sale: sort that out first. Selling on a car still registered to someone else creates a paperwork gap that lands back on you.
- Buyer drives off before the new keeper details are logged: this is exactly why you notify the DVLA the same day, not "sometime this week".
The mistake that costs sellers weeks later
A speeding fine, a congestion charge, or a parking ticket on the car goes to whoever the DVLA has on file as the keeper, regardless of who was actually driving. Sellers who hang onto the V5C for a few extra days, meaning to send it off later, are the ones who end up disputing a fine for a car they no longer own. It takes minutes online. Do it the same day.
