Used Car Papers and Service History: A Document-by-Document Check Before You Pay
A used car can look perfect in daylight and still be a bad purchase because of its paperwork. Pending loans, missing records, insurance gaps or mismatched numbers can turn into long, costly problems after you've paid. Most guides focus on how the car drives. This one is about the documents and the history behind it, in the order in which you should check them. Use it alongside our general used car buying guide, which covers the test drive and inspection.

Before you start
- This is practical guidance based on common processes. Forms, fees and procedures can differ by state and change over time, so confirm current requirements with your local transport office or a trusted professional.
Ask for the documents before the test drive
- If the seller is hesitant to show papers, treat that as information. Ask for clear photos on a messaging app first, then inspect the originals in person.
The document check, one by one
- Registration Certificate (RC) — What to look for: Owner's name, registration number, chassis and engine numbers, fuel type, registration date; Red flag: Name differs from the seller, with no clear explanation
- Insurance policy — What to look for: Valid dates, type of cover, insured name; Red flag: Expired policy, or a very recent policy bought only for sale
- Pollution Under Control (PUC) certificate — What to look for: Valid date for the car's registration number; Red flag: Missing or expired with no willingness to renew
- Service book and bills — What to look for: Regular entries, workshop stamps, mileage over time; Red flag: Missing book, or all entries made in one handwriting on one day
- Loan papers — What to look for: Whether a loan was ever taken; hypothecation noted on the RC; Red flag: Loan on the RC with no closure papers
- Road tax receipt — What to look for: Tax paid details, where applicable; Red flag: Unclear or missing
- Challan history — What to look for: Any pending traffic fines; Red flag: Many unpaid fines with no plan to clear
- Owner's ID — What to look for: Name and address matching the RC; Red flag: A different name, no ID, or refusal to show it
Match the numbers on the car
- Open the bonnet and check the chassis number stamped on the body, and the engine number on the engine block. Compare both with the RC. Also match the registration plate with the RC. Differences, rubbed-off digits or signs of re-stamping are serious warnings. Walk away unless there is a documented explanation you can verify.
Understanding the service history
- A good service history tells a story. Look for:
- Regular intervals. Services roughly in line with time or distance, rather than long gaps.
- A consistent workshop. A trail from an authorised or reputable workshop is reassuring.
- Major repairs. Ask about accidents, engine or gearbox work, and flood or water damage. Request bills for large repairs.
- Odometer consistency. Mileage in records should rise logically, and match what the meter shows.
- If there is no service book, it doesn't automatically make the car bad, but it means you must rely more on an independent mechanic's inspection.
Loan and hypothecation
- If a loan was taken on the car, the lender's name may be noted on the RC. Before purchase, you need proof that the loan was closed and the lender's record removed. Typically this means lender-issued closure papers and the related paperwork to remove the entry from the RC. Without these, you may not be able to transfer the car in your name. Ask the seller to complete this before you pay the balance, or have it written in the agreement with a clear timeline and part-payment held back.
Challans and past records
- Pending traffic fines are linked to the vehicle number, and they may be a nuisance when you take over. You can often check them by vehicle number on the official Parivahan e-challan portal (echallan.parivahan.gov.in). Ask the seller to clear any pending ones before the sale. Also ask whether the car was ever used as a taxi or a rental vehicle, since this affects wear and the registration type.
Insurance and claims
- Ask whether any insurance claims were made and for what. A car with a major claim isn't necessarily bad if repaired properly, but you should know. Check that the policy can be transferred to your name after sale; this is usually done through the insurer.
Paying safely
- Don't pay a large advance before documents are verified.
- Use bank transfer or another traceable method, and avoid large cash payments.
- Prepare a written sale agreement with the car details, price, date and what is being handed over.
- Agree who will complete the ownership transfer, and by when.
- Keep copies of every paper, the seller's ID and all payment proofs.
- Our safe deal checklist covers meeting places and payment habits in more detail.

Frequently asked questions
Can I buy a car without a service book?
You can, but get a trusted mechanic to inspect it and be more careful about price and history.
What if the owner is not the person selling?
Ask for a clear authorisation and ID proof of the registered owner. If you cannot verify, do not proceed.
Should I buy a car with a loan still on it?
Only if the loan is closed before or as part of the deal, with documents to prove it.
Who transfers the ownership?
Both sides have steps. Agree in writing who will do what and by when, and confirm the current procedure with your transport office.
Is a very low price a good sign?
Not by itself. Very low prices often point to paperwork or condition problems; ask why.
