Fixed fine, criminal fine pronounced by a judge, monetary conviction: these three terms refer to distinct legal realities, with very different consequences on the wallet, criminal record, and possibilities for appeal. The confusion is common, including on payment notices received by mail. This article compares their mechanisms, effects, and respective pitfalls.
Fixed fine, criminal fine, and monetary conviction: comparative table
| Criterion | Fixed fine | Criminal fine (non-fixed) | Monetary conviction |
|---|---|---|---|
| Origin | Automated or electronic ticket, without going before a judge | Pronounced by a court after a hearing | Pronounced by a judge, collection by the public treasury |
| Offenses targeted | Contraventions of the first 4 classes (and certain offenses since the extension of the fixed fine for offenses) | 5th class contraventions, offenses, crimes provided for by a text | Any penal offense judged, including legal costs and damages |
| Amount | Set by law according to the class, with possible reduction or increase | Set by the judge within the limits of legal ceilings | Set by the judge, sometimes includes costs and repairs |
| Payment and public action | Payment extinguishes public action and constitutes acknowledgment of the offense | Payment does not prevent the exercise of appeal rights | Payment does not prevent appeal, opposition, or cassation |
| Criminal record entry | In principle no, except for recent developments for fixed fines for offenses | Yes, depending on the nature of the offense | Yes |
This table highlights a structural difference: the fixed fine relies on a rapid processing mechanism, without a judge, while the classic criminal fine and monetary conviction require an adversarial judgment.

Payment of the fixed fine: why it constitutes acknowledgment of guilt
The most underestimated trap of the fixed fine can be summarized in one sentence: paying means giving up contesting. Articles 529 to 530 of the Code of Criminal Procedure provide that the payment of a fixed fine extinguishes public action. Practically, once the payment is recorded, contestation becomes nearly impossible, except in very limited cases (license plate fraud, vehicle theft).

In contrast, a monetary conviction resulting from a judgment follows a different circuit. The public treasury ensures collection, but the avenues for appeal remain open regardless of payment. Appeal, opposition, cassation: having paid the amount due does not close any procedural doors.
This asymmetry has direct practical consequences. A motorist who receives a radar ticket and pays it on time (possibly with a reduction) definitively settles the matter. A defendant sentenced to a fine by a correctional court can pay the amount while appealing the judgment.
Deadlines and reduction: the specific mechanism of the fixed fine
The fixed fine operates on a three-tiered scale:
- The reduced amount applies if payment occurs within a short period after notification (varies depending on the method of delivery of the ticket).
- The base fixed amount corresponds to the legal rate for the class of contravention concerned.
- The increased amount automatically applies in case of non-payment within the deadlines, without a new judicial decision.
This automatic increase radically distinguishes the fixed fine from a classic monetary conviction, where any increase in the amount due requires a judicial decision or a forced collection procedure initiated by the public treasury.
Monetary conviction after judgment: what this term really covers
The term “monetary conviction” appears on some payment notices received by mail, which creates frequent confusion. It does not refer to a specific type of fine but the total amounts due following a criminal judgment: the fine itself, legal costs (expenses), and sometimes damages awarded to the civil party.
Collection is entrusted to the Directorate General of Public Finances. The site amendes.gouv.fr allows for the payment of monetary conviction notices before the initiation of proceedings, just like increased fines or post-parking fees.
Criminal record and fixed fine for offenses: a shifting boundary
Traditionally, the fixed fine left no trace on the criminal record. The situation is evolving with the extension of the fixed mechanism to certain offenses (use of narcotics, illegal occupation of land, for example). The “RIPost” law of 2026 has reignited the debate on the registration of fixed fines for offenses on bulletin n°2 of the criminal record.
The consequences go beyond the simple payment of a sum of money. Bulletin n°2 is consulted by administrations during the recruitment of civil servants, by professional orders, and for access to certain competitions. A fixed fine for an offense registered on the criminal record can therefore impact employment or the practice of a regulated profession, which the “without judge” mechanism of the fixed fine did not initially suggest.
Contest or pay: decision criteria according to the type of sanction
The choice between immediate payment and contestation directly depends on the nature of the sanction received. Three criteria help to decide:
- If it is a classic fixed fine (contravention of classes 1 to 4), paying the reduced amount within the deadlines often remains the least costly solution, except for a manifest error on the ticket.
- If it is a fixed fine for an offense, checking the possible consequences on the criminal record before paying is essential, as payment constitutes acknowledgment of the facts.
- If it is a monetary conviction resulting from a judgment, the avenues for appeal (appeal, opposition) remain open even after payment, which leaves a margin of maneuver absent from the fixed system.
The distinction between these three mechanisms is not just a legal nuance. It determines the final amount, the possibility of contesting, and the traces that the sanction leaves in the administrative history of the offender. Carefully reading the exact title of the notice received, whether it mentions “fixed fine,” “increased fine,” or “monetary conviction,” remains the first reflex to adopt before any payment decision.
