If you want to know how to SORN a car you have just bought, the good news is that you do not need to wait for the new logbook to arrive. Using the V5C/2 — the green new-keeper supplement handed to you by the seller — you can declare a Statutory Off Road Notification immediately after purchase. The SORN takes effect from the moment it is confirmed.
Key takeaways
- When you buy a car privately, the seller gives you the green V5C/2 new-keeper supplement.
- You can use the reference number on the green slip to declare SORN before your replacement V5C logbook arrives from the DVLA.
- Using a V5C-type reference number means your SORN takes effect immediately — not from the start of next month.
- SORN does not expire on its own. It stays in place until you tax the vehicle, sell it, scrap it, or export it permanently.
- The previous keeper's road tax is cancelled automatically when ownership transfers — you start without any tax, so you must act promptly.
- An untaxed vehicle with no SORN can attract an automatic £80 penalty from the DVLA.
What is the V5C/2 green new-keeper supplement?
When a vehicle is sold privately, the seller fills in the relevant section of the V5C logbook and sends the main document to the DVLA. The green perforated slip at the bottom of the logbook — the V5C/2 — is detached and handed to you as the new keeper. It serves as temporary proof that the vehicle has transferred into your name while the DVLA processes the change of keeper and posts you a replacement logbook.
The green slip does more than confirm the transfer. It carries a reference number that the DVLA's online systems recognise, allowing you to tax or SORN the vehicle immediately — without waiting weeks for a new V5C to arrive on your doorstep.
Why you might want to SORN a car you have just bought
There are many reasons a new keeper needs to SORN a vehicle straight away:
- The car is a project or restoration that will not be driven for some time.
- It has no current MOT and cannot legally be used on the road until one is arranged.
- You are waiting for insurance to be set up before driving.
- You have bought the car as a spare or a vehicle to store for the future.
- You want to keep it on a private driveway or in a garage without paying road tax.
Whatever the reason, acting quickly matters. When ownership changes hands, the previous keeper's road tax is cancelled by the DVLA automatically — it does not transfer to you. From the moment you become the new keeper, the vehicle is untaxed. If you are not going to tax it straight away, you need to SORN it. An untaxed vehicle with no SORN can result in an automatic £80 penalty from the DVLA.
If the car will be kept on your driveway or another piece of private land, our guide on whether you need to SORN a car kept on private land or a driveway explains the rules in full.
How to SORN a car you have just bought using the green slip
The process is simpler than many new keepers expect. Before you start, have the V5C/2 to hand — you will need the reference number printed on it.
Step 1: Find the reference number on the V5C/2
Look near the top of the green slip for the document reference number. This is the 11-digit number that identifies the vehicle in the DVLA's system and tells the DVLA you are the new keeper making the declaration.
Step 2: Choose your declaration method
You have three options:
- Online: The quickest method. Visit the DVLA's SORN service on GOV.UK, enter the reference number when prompted, and follow the steps. Confirmation is immediate.
- By phone: Call the DVLA on 0300 123 4321 (Monday to Friday, 8am to 7pm; Saturday, 8am to 2pm). Have the green slip to hand before you call.
- By post: Complete form V890 and send it to the DVLA. This method takes longer and your SORN will not be active until the letter has been processed and confirmed.
You can declare SORN for free yourself directly on the GOV.UK website. SORN My Car is an optional paid service that handles the paperwork on your behalf if you would prefer not to deal with it yourself.
Step 3: Keep your confirmation
Once you have declared online or by phone, the DVLA will send a confirmation letter — typically within five working days. Keep it safe. It is your proof that the vehicle is correctly SORNed while you wait for your new V5C logbook.
When does your SORN take effect?
The timing depends on which reference number you use:
- A reference from the V5C or V5C/2 green slip (11 digits) means the SORN takes effect immediately.
- A reference from a V11 renewal reminder (16 digits) means the SORN takes effect from the first day of the following month.
As a new keeper using the V5C/2, you will be using the V5C-type reference, so your SORN is active from the moment it is confirmed. This is exactly what you need when a vehicle has just changed hands and must be taken off the road without delay.
What happens while you wait for the new V5C?
After you declare SORN using the green slip, the DVLA simultaneously processes the change of keeper. Your new V5C logbook — showing you as the registered keeper — should arrive within around six weeks. In the meantime, your SORN is fully in force and the vehicle is legally covered as long as it remains on private land.
It is also worth knowing that SORN does not expire automatically. It stays in place indefinitely until you tax the vehicle again, sell it, have it scrapped, or permanently export it. You do not need to renew it each year.
What if there is no green slip?
Occasionally the V5C/2 goes missing. The seller may have forgotten to detach it, sent it to the DVLA by mistake, or it may have been lost before you collected the car. If you have no green slip and your new V5C has not yet arrived, contact the DVLA on 0300 123 4321 as soon as possible. They can advise on next steps, which may include requesting a replacement logbook. Once you have a reference number, declare SORN immediately.
Do not leave the vehicle untaxed and un-SORNed while you sort this out. If the car is visible near a public road, DVLA enforcement systems may flag it, and the £80 penalty can be issued automatically without further warning.
Buying at auction or through a dealer
If you purchased the vehicle through a dealership or at auction, the paperwork process differs slightly. Dealers often retain the V5C and notify the DVLA of the change of keeper themselves, which means you may not receive a V5C/2 at all. Before you leave, ask whether the dealer will issue you the green slip or whether they are handling the DVLA notification on your behalf. If no green slip is available, ask for the document reference number so you can declare SORN without further delay.

Can you drive a car you have just bought before SORNing it?
No. As soon as ownership transfers to you, the car must be either taxed or SORNed. You cannot drive an untaxed, un-SORNed vehicle on a public road — even for a short journey to take it home. If the car is on private land where you collected it, declare SORN before moving it onto any public road. If you need to move it for a specific reason such as a pre-booked MOT, check the precise conditions that apply before doing so.

Start your SORN ›Frequently asked questions
Can I use the V5C/2 green slip to declare SORN if I have never been registered as a keeper before?
Yes. The V5C/2 is specifically designed for new keepers and is accepted by the DVLA's online SORN system. You do not need to have been a previous registered keeper or to have completed the full change-of-keeper process before declaring. The green slip reference is sufficient to make the declaration in your name straight away.
Does the previous owner get a road tax refund when I SORN the car after buying it?
The previous keeper's road tax is cancelled automatically by the DVLA when the vehicle changes hands, and any remaining complete months are refunded to them — not to you. As the new keeper you start without any existing tax on the vehicle. SORNing the car simply means you are not required to take out a new tax licence while it stays off the road.
What should I do if the seller forgot to give me the V5C/2 green slip?
Contact the DVLA on 0300 123 4321 as soon as possible. Explain that you are a new keeper who did not receive the supplement. The DVLA can advise on how to obtain a reference number — for example, by requesting a replacement V5C — so you can declare SORN without further delay. Keep any evidence of the purchase date in case you need to show you acted promptly.
If I buy a car at auction, will there be a green slip available to declare SORN?
Not always. Auction houses and dealers typically handle the DVLA notification themselves and may not hand over a V5C/2. Before leaving, ask the auction house whether they can issue the green slip or provide the document reference number you need. If neither is available immediately, follow up as quickly as possible — the vehicle still needs to be taxed or SORNed without delay once it is in your possession.
Can I declare SORN before I physically collect the car from the seller?
In practice, no. The SORN must be declared by you as the new keeper, using the reference number on the green slip which is handed over at the point of sale. The declaration is most straightforwardly made at the time of purchase or immediately afterwards — ideally before the vehicle is moved onto a public road for the first time.
If the car I have just bought was already SORNed by the previous owner, do I need to declare it again?
Yes. A SORN is linked to the registered keeper, not the vehicle in isolation. When ownership transfers, the previous keeper's SORN does not automatically carry over to you. Once you become the new keeper, you need to make a fresh SORN declaration in your own name using the V5C/2 reference number. Do not assume the existing SORN covers you.
