The short answer: when buying a car from a private seller in the UK, you need the V5C logbook, a valid MOT record, proof the seller genuinely owns the car, a vehicle history check, insurance in place before you drive away, and a written receipt. You also need to pay safely and tax the car in your own name straight away.
Private sales don't come with the protections a dealer has to offer, so the checking is down to you. Here is the full checklist.
Documents to get from the seller
- V5C logbook (registration certificate): This shows the registered keeper, not strictly proof of ownership, but it is the key document. Check the seller's name and address match the V5C and ideally view the car at that address. Be very wary if the seller has no V5C or says it is 'in the post'.
- The new keeper slip: The V5C includes a section for the buyer. Make sure the seller fills in the sale details with you and gives you the new keeper slip.
- MOT certificate and history: You can look up a car's MOT history online using the registration number. Look at past failures, advisories and recorded mileage.
- Service history: Stamped service books or invoices show how the car has been looked after.
- Spare keys and manuals: A missing second key can be expensive to replace.
Check the car's history before you pay
A car can look perfect and still have a hidden past. Before handing over money, check the following:
- Insurance write-off status: The MIAFTR database records vehicles declared write-offs. Cat A and B cars should never return to the road (Cat B can only be broken for parts), while Cat S (structural) and Cat N (non-structural) can be repaired and driven again. These cars can still be sold, but they are usually worth less and you should know before you buy.
- Stolen marker: Police National Computer (PNC) data can show whether a car has been reported stolen. Buying a stolen vehicle can mean losing both the car and your money.
- Outstanding finance: If a car is still subject to finance, the lender may have a claim on it, even after you have paid the seller. This is one of the biggest risks in private sales.
- Mileage: Compare the dashboard mileage with MOT records. A sudden drop or odd gaps can suggest clocking or an error.
- Previous keepers: A high number of owners in a short time can be worth asking about.
- Plate and colour changes: Check the VIN and engine number match the V5C, and that the colour matches the record.
You can run these checks by entering the vehicle's registration on motorpeek.com before you view the car or agree a price. Treat any report as one part of your checks rather than a substitute for inspecting the car yourself.
Inspecting and test driving
View the car in daylight and dry weather if you can. Look for uneven panel gaps, mismatched paint, rust, warning lights, damp smells and worn tyres. Start the engine from cold. Make sure you are insured to test drive (many policies offer limited cover for other cars, but check yours) and that the seller's car is taxed, MOT'd and insured for you to drive. If you are not confident, consider paying for an independent inspection.
Paying safely
- Prefer a bank transfer to carrying a large amount of cash, and never pay a deposit to someone you haven't met.
- Be cautious of pressure to decide quickly, sellers who won't meet at their home address, or prices that look too good to be true.
- Don't hand over payment until you have seen the V5C and completed your checks.
Get a receipt
Ask for a written receipt that includes:
- The date, price and payment method
- The car's make, model, registration and VIN
- Both parties' names and addresses
- The mileage at sale
- A statement that the car is sold as described
Both of you should sign it and keep a copy. Private sellers don't have the same obligations as traders, but the car must be as described and the seller must have the right to sell it. A receipt makes any dispute easier to deal with.
After you buy: tax and insurance
Insurance: You need cover in place before you drive away. It is illegal to drive uninsured.
Vehicle tax: Tax does not transfer to the new owner. You must tax the car in your name before driving it on public roads. This can usually be done online using the reference number on the V5C.
Tell the DVLA: The seller should notify DVLA of the sale, and you should make sure the new keeper details are sent so the car is registered to you. Keep the new keeper slip until your own V5C arrives.

Frequently asked questions
What documents do I need when buying a car from a private seller?
The most important is the V5C logbook, plus the MOT certificate or online MOT history and any service records. Make sure the seller's details match the V5C, and ask for a written receipt. You'll need your own insurance and to tax the car in your name before driving it.
Can I get a car with outstanding finance from a private seller?
It is possible, but risky. If finance is still owed, the lender may have a legal claim on the car, even if you paid the seller in full. Run a vehicle history check that covers outstanding finance before paying, and walk away if the seller can't clear it properly.
Is it safe to pay cash for a car from a private seller?
Large cash payments are riskier because they leave little record and can attract scams or theft. A bank transfer after you've seen the V5C and finished your checks is generally safer. Always get a signed receipt showing the price, date and car details.
