RTO & Ownership Transfer

PUC Certificate Rules When Selling a Car

By Bill My Car · Updated 6 August 2026 · 5 min read

A valid Pollution Under Control (PUC) certificate belongs in the document set handed over at a car sale, and RTOs commonly ask for it alongside the original registration certificate and insurance copy when a transfer is processed. It is a small document that stops a transfer when it is missing.

It is also the one document in the set that expires on its own schedule, which is why it is the one most often found lapsed on the day of sale.

Where the PUC sits in a sale

The buyer's document set at the RTO typically includes ID proof, address proof, passport-size photographs, the original RC, and copies of the insurance and PUC certificate. See the full used car paperwork checklist.

Who arranges it

The seller. The PUC is issued against the vehicle after an emissions test, and the seller is the person with the car in hand before delivery.

Standard used-vehicle Terms and Conditions list the PUC certificate among the documents the dealer provides, next to the original RC book, the valid insurance certificate, Form 29 and Form 30, and the financier's NOC where a loan existed. Listing it there and having the buyer sign against the list is what prevents the later argument that it was never handed over.

The certificate follows the vehicle, not the owner

A PUC is issued against the registration number. It does not lapse because the car changed hands, and it does not need to be reissued in the buyer's name. Whatever validity remains carries over, and the new owner renews it when it runs out.

This is the opposite of insurance, which is tied to the owner and must be transferred to the new owner separately. Sellers frequently confuse the two and assume both transfer automatically. Only the PUC does.

Validity, and why it catches people out

Validity periods differ between new and older vehicles, and the durations and testing fees are set under state rules and revised over time. Read the expiry printed on the certificate rather than assuming a period, and confirm the current rules with your local RTO or an authorised testing centre.

The practical failure is not the rule, it is the calendar. A certificate that was valid when the car was listed can expire during the weeks it takes to find a buyer and complete the paperwork. Check the date again on the day of delivery, not on the day you listed.

Driving without a valid PUC is an offence under the Motor Vehicles Act, 1988, and penalties are enforced. Amounts have been revised and vary by state, so treat the certificate as non-optional rather than budgeting for the fine.

For dealers

Make the PUC a checkpoint at two points, not one.

At intake. When a car enters stock, record the PUC expiry alongside the RC, insurance and challan check. A unit whose PUC expires next month is a unit that will need a test before it can be delivered. Fold this into your inventory records so it surfaces before a buyer is waiting.

At delivery. Verify the certificate is still valid on the handover date and list it on the delivery note among the items handed over, with the RC, insurance, keys and tool kit.

Dealers holding stock for weeks or months are the ones most exposed to a silent expiry, because the certificate was valid when they bought the car and nobody looked again.

If the PUC has lapsed on the day of delivery

This is the common case, and it is fixable. The vehicle is tested at an authorised emission testing centre and a fresh certificate is issued against the registration number, usually the same day.

The complication is a vehicle that fails. A car that will not pass needs the underlying issue attended to before it can be certified, and that is a repair conversation, not a paperwork one. For a dealer with a buyer waiting and payment received, it is also a delivery date missed.

Two habits prevent it:

• Test at intake, not at delivery. If the certificate is close to expiry when the car enters stock, renew it then. You have time; the buyer will not give you any.
• Do not accept a certificate you have not seen. A seller's assurance that the PUC is valid is not the same as an in-date certificate in your hand.

If a lapse is discovered mid-transaction, put the position in writing: who arranges the test, who pays, and whether delivery moves. An informal promise here becomes an argument later.

PUC, insurance and the renewal chain

The three documents on a car run on independent clocks, and the PUC is the shortest.

There is one linkage worth knowing: insurers in India generally require a valid PUC at the point of policy renewal. So a lapsed PUC does not just stall an RTO transfer, it can stall the insurance renewal that the buyer needs in order to complete the ownership change cleanly.

For a dealer this compounds. A unit with a lapsed PUC and an expiring policy is two problems arriving in the same week, both discovered when a buyer is ready to pay.

Interstate sales

A car being sold to a buyer in another state needs its emissions position to be in order before it re-registers, and destination-state requirements can be stricter than the state of origin. Several metro areas enforce the prevailing emission norms and will not register vehicles that do not comply.

Check the destination RTO's position before agreeing the sale, not after the NOC on Form 28 has been issued. The full sequence is in selling a car to a buyer in another state.

The short version

• The PUC belongs to the vehicle and carries over to the buyer with its remaining validity.
• The seller arranges it, and lists it among the documents handed over.
• Check the expiry on the delivery date, not the listing date.
• Confirm what your RTO requires for transfer, because practice varies.

Bill My Car generates the delivery note, the Terms and Conditions and the RTO forms from one invoice entry, with the handed-over document list ready for the buyer to sign against. Sign in and generate your handover set.

Validity periods, testing fees and penalty amounts are set by state rules and change over time. Confirm current requirements with your local RTO or an authorised testing centre.
