Buying a Used Car? The No Claim Bonus Does Not Transfer to You

Ask a seller about the insurance on a used car and you will often hear a confident, reassuring line: "It has full No Claim Bonus, so your insurance will be cheap." It sounds like a bonus that comes with the car — a discount you inherit along with the keys. It is not. The No Claim Bonus (NCB) is one of the most misunderstood parts of a used car deal, and the misunderstanding costs buyers money. The plain truth is this: the NCB belongs to the person who earned it, not to the vehicle. When the car changes hands, the No Claim Bonus does not transfer to you. As the buyer, you start at zero.

That single fact quietly reshapes what a used car really costs you in its first year. It also sits alongside a second surprise most buyers never see coming — that when a car is sold, only the third-party section of the insurance automatically extends to the new owner for a short window, while the own-damage cover that actually protects the car does not follow it at all. This article unpacks both, using the IRDAI-recognised NCB slabs, so you can budget the renewal correctly and verify the seller's story against the record before you pay.

What the No Claim Bonus Actually Is

The No Claim Bonus is a discount that rewards you for not making a claim. Every full year you hold motor insurance without claiming, the bonus grows and cuts your next renewal. The IRDAI-recognised NCB slabs are standard across insurers, so the numbers are the same wherever the policy sits:

Two details in that table matter enormously to a buyer. First, the bonus tops out at 50% after five or more consecutive claim-free years — a meaningful cut. Second, and this is the part sellers skip, the discount applies only to the own-damage (OD) portion of the premium, not to the third-party (TP) portion. The mandatory third-party cost stays the same regardless of how spotless the record is. So even a full 50% NCB never wipes out the whole premium; it only trims the own-damage slice.

There are two ways the bonus can vanish, and both are worth knowing before you rely on any claim about it. One claim resets the NCB to zero. And a lapse of more than 90 days — a 91-day gap between one policy ending and the next beginning — wipes the accumulated NCB permanently. That is exactly why a used car with a policy that quietly lapsed is doubly damaging, a point we cover in the section below.

Why the NCB Cannot Follow the Car to You

Here is the crucial fact that undoes the seller's pitch: the No Claim Bonus is tied to the insured person, not to the vehicle. It is a reward for how carefully that individual has driven and insured, and it travels with them, not with the metal. When the car is sold, the bonus the seller built up cannot be handed over with the keys. The buyer simply does not inherit it.

So where does the bonus go? It stays with the seller. When someone sells a car, they can ask their insurer for an NCB retention letter (also called a reservation letter). That letter lets the seller carry the earned bonus to their next car's policy — and it is transferable between insurers on renewal, provided they show proof. The bonus the seller earned is genuinely theirs to keep and reuse; it was never yours to receive. For you, the buyer, that means your first year of own-damage cover on the car you just bought is priced at the full rate with 0% NCB, and you begin building your own bonus from scratch from that point.

The 14-Day Window: What Transfers and What Does Not

The NCB is not the only thing that behaves differently from how buyers assume. When ownership changes, the Motor Vehicles Act provides a 14-day window from the ownership change to complete the insurance transfer. It is tempting to read that as "I am covered for 14 days on the seller's policy". You are not — at least, not fully.

During those 14 days, only the third-party section of the policy automatically extends to the new owner. That protects other people and their property if you are at fault — the legally mandatory part. The own-damage section does not transfer until you formally apply and the insurer endorses the policy in your name. In plain terms: for the first two weeks, the law keeps the third-party cover alive so the road stays safe, but the cover that pays to repair the car you just bought is switched off until you complete the transfer. If the car is damaged in that gap before the endorsement is done, you can be left carrying the repair yourself.

Why the endorsement is not just paperwork

IRDAI guidance is that the insurance policy should bear the same name and address as the registration certificate. If you skip the transfer and the policy stays in the previous owner's name, the record says one person owns the car while another holds the insurance — and that mismatch has consequences. An own-damage claim can be rejected if the policy is still in the previous owner's name and has not been endorsed. On paper, the insured person no longer owns the car, so the insurer can decline. Getting the policy endorsed into your name is what keeps your own-damage cover actually enforceable, which is why our guide to why insurance claims get rejected on used cars puts name-mismatch at the top of the list.

What This Costs You: A Real-World Example

Picture a buyer in Hyderabad eyeing a well-kept sedan. The seller says, honestly enough, that the car has five claim-free years and a full 50% No Claim Bonus, and points to it as a reason the car is worth a little more. The buyer mentally files the insurance as "sorted" and pays.

Two things then unfold. First, the 50% bonus does not come to the buyer at all — it leaves with the seller, who can retain it for their next car. When the buyer renews, the own-damage premium is charged at the full rate with no NCB, higher than the buyer had loosely assumed. Second, the buyer relied on the seller's still-valid policy and delayed the transfer. Ten days in, a minor parking knock damages the bumper; because the own-damage section never transferred and the policy still names the previous owner, the own-damage claim is refused. The "full NCB, fully insured" car ends up costing more on renewal and leaves the buyer paying for a repair out of pocket — all from two assumptions that a two-minute check would have corrected. To understand what the renewal should actually contain, our explainer on comprehensive versus third-party cover is worth reading alongside this piece, and if you want the mechanics of the ownership change itself, see our guide to the 14-day RC transfer rule.

Verify Before You Pay — Because the Cover Does Not Follow the Car

Put the two facts together and the buyer's job is clear. Because the own-damage cover does not follow the car and your NCB resets to zero, you cannot lean on the seller's insurance to protect you — you have to confirm two things before any money moves. One, that the policy is genuinely valid and you know when it expires, so you can budget the renewal at full own-damage rate. Two, that the policy and owner details on record match what the seller is telling you, so the endorsement into your name goes through cleanly and no future claim is exposed to a name mismatch.

Both of those live in the vehicle's official record, and you do not have to piece them together yourself. A single Rs. 49 Vahan Verify check on VahanBazaar pulls the car's full VAHAN record — insurance validity, owner count, registration status and challan flags — in one lookup. It confirms the insurance validity and lets you match the seller's claim to the record, so you can budget the renewal and the endorsement correctly instead of being surprised on day one. Run it from your phone the moment a car makes your shortlist, before you spend a Saturday travelling to see it. For the wider context of long-term policies, note that since 2018, all new private cars must carry a minimum three-year third-party policy at purchase, and insurers may offer long-term motor policies up to a maximum of three years — worth knowing when a relatively new used car still sits inside that original term.

What This Means for Used Car Buyers

The No Claim Bonus is a reward for the seller's driving history, not a feature of the car, so it never becomes yours — you start at 0% NCB and build your own from scratch, even if the seller genuinely earned the full 50%. The 14-day window after the sale keeps only the third-party cover alive; the own-damage cover that repairs your car does not transfer until you get the policy endorsed in your name, and an own-damage claim can be refused while the policy still names the previous owner. None of this is a reason to avoid buying used — it is a reason to buy used with your eyes open and your budget honest.

The practical discipline is simple. Do not price the car around an NCB you will not receive. Transfer and endorse the insurance into your name on day one rather than resting on the seller's policy. And before you pay, verify the insurance validity and owner details against the record with a Rs. 49 Vahan Verify check on VahanBazaar so the "full NCB, fully insured" pitch either matches the government data or it does not. The buyer who understands that the bonus stays with the seller budgets correctly and drives home protected; the buyer who assumes it comes with the keys finds out otherwise at renewal — or worse, at the claim counter. As the market's own tools evolve, our look at Bima Sugam and the used car gap covers where renewals are heading, but the pre-purchase rule holds: verify, then buy.
