You have just been checked in the metro or RER, and the inspector offers you to pay immediately. Before taking out your credit card or tickets, there are a few elements that deserve your attention. The amount, the accepted payment methods on site, and especially the consequences of this immediate payment are not always clear at the moment the situation arises.
What happens during a RATP inspection
The inspector checks your transport ticket. If you do not have one, or if it is invalid (expired pass, unvalidated ticket, uncovered zone), he writes a report. This report is a contractual document, not a criminal sanction.
At this stage, two options are available. Either you pay on the spot, or you receive a notice of violation to pay later. Many travelers choose the first option to resolve the situation quickly, without always realizing what it entails.
When you decide to pay a RATP fine on the spot, the inspector gives you a receipt. This receipt is the only proof of your payment. Keep it: without this document, it will be very difficult to prove that you have already paid if a reminder letter arrives a few weeks later.
Payment on the spot can be made in cash or by credit card. Checks are not accepted on the RATP network, whether on site or by mail. Any check sent is destroyed, and sending it does not suspend the payment deadlines.
Amount of the RATP fine and payment deadline: the arbitration to know
The amount requested on the spot has recently changed. According to testimonies relayed by inspectors and users, the immediate fine has increased from 50 to 70 euros. This increase changes the game for travelers who thought that paying immediately was necessarily the cheapest option.

If you do not pay on the spot, you have a deadline to settle. And this is where a detail matters: a payment within 20 days offers a 20 euro discount on the processing fees. This discount applies to online payment via the site pv.ratp.fr, by phone at 3424, or at a RATP sales point.
On the other hand, exceeding this deadline results in a surcharge. The unpaid fine eventually gets transferred to the public treasury, where the amount increases significantly. At this stage, it is the treasury that manages the collection, with heavier enforcement measures (wage garnishment, bank account seizure).
- Payment on the spot: immediate settlement with the inspector, receipt handed over in person, by card or cash only.
- Payment online or by phone: possible from 5 days after the report, 20 euro discount if done within 20 days.
- Payment at a RATP sales point: generation of a QR code on pv.ratp.fr to facilitate payment in cash or by credit card.
- Beyond the deadline: transfer to the public treasury, increased fine, possible forced collection procedures.
Paying on the spot does not prevent contesting the RATP fine
You paid right after the inspection, but you believe the report was not justified? Paying does not close the door to a contestation. Payment on the spot is a civil transaction, not an admission of guilt.
Let’s take a concrete example. Your Navigo pass was active, but the validator did not detect your card. The inspector issues a ticket. You pay to avoid blocking the situation. In this case, you can file a complaint by providing proof that your ticket was valid at the time of the inspection.
How to file a complaint after payment
The RATP provides a dedicated form for fines paid on the spot, accessible from the contact page of pv.ratp.fr. The deadline to contest is three months after the report. After this window, the chances of obtaining a gesture decrease significantly.
Some users manage to have their fine converted into a simple warning, provided they demonstrate the absence of intent to defraud. An active subscription not recognized by the terminal, a technical issue with the app, a valid ticket not validated by mistake: these documented situations can lead to cancellation or reimbursement.
Unpaid RATP fine: what you really risk
Not paying a RATP fine does not automatically lead to a criminal record. As long as no court has pronounced a conviction, there is no criminal record. This is a point that many travelers are unaware of.
The real risk lies on the financial side. An ignored fine follows a predictable path: follow-up by RATP, then transfer to the competent treasury. The increased amount, plus collection fees, can represent several times the initial price.
The treasury letter usually arrives at the address declared during the report. If you have moved in the meantime without updating your contact details, you risk never receiving it, which does not suspend the procedure.
Contacting the right service in case of dispute
For any questions about an unpaid fine, 3424 remains the main point of entry (free service, cost of a call). The hours are broad: Monday to Friday from 7 am to 9 pm, weekends and holidays from 9 am to 5 pm.
For more specific requests (amount error, double charge, lost receipt), RATP offers separate forms depending on the nature of the problem. One form for unpaid fines, another for fines paid on the spot, and a third for special cases.

Paying the RATP fine on the spot remains a subject where haste rarely works in the traveler’s favor. Keeping your receipt, checking the amount, and knowing the 20-day deadline to benefit from the discount are the three reflexes that avoid most unpleasant surprises. And if the report seems unjustified to you, having paid does not deprive you of the right to contest it.
