Every day, French consumers and foreign residents in France are exposed to thousands of advertising messages on the internet, social media, or in physical stores. While commercial freedom allows businesses to promote their products, French law strictly regulates commercial communication to protect buyers from unfair practices. When faced with a misleading promotion, a fake price reduction, or exaggerated technical specifications, French law offers powerful remedies to restore justice and punish dishonest practices. This comprehensive guide explains how to identify misleading advertising, how to report it effectively, and the heavy sanctions faced by unscrupulous professionals.

In French law, the historical concept of "misleading advertising" is now integrated into the broader category of misleading commercial practices (pratiques commerciales trompeuses or PCT). These practices are defined and punished by the Code de la consommation (French Consumer Code).
The legal arsenal relies primarily on *Article L. 121-2 of the Code de la consommation***. According to this text, a commercial practice is misleading if it is committed in any of the following three situations:
1. Creating confusion: When it creates confusion with another good or service, a trademark, a trade name, or another distinctive sign of a competitor.
2. False allegations or presentations likely to mislead: When it relies on allegations, indications, or presentations that are false or likely to mislead the average consumer.
3. Omission of substantial characteristics: When the identity of the professional, the price including all taxes (toutes taxes comprises or TTC), or the essential characteristics of the good or service are hidden or presented in an obscure manner (this is also known as misleading omission, governed by *Article L. 121-3 of the Code de la consommation***).
The law lists specific elements on which the consumer must not be misled:

To better understand how the law applies in practice, here are two concrete situations inspired by common disputes in French courts.
Example: Marie wants to buy a laptop displayed on an e-commerce site with the mention "-50% exceptional discount, i.e., 600 € instead of 1200 €". Attracted by this opportunity, she places an order. A few days later, she realizes through a price history tool that this laptop was never sold for 1200 € on this site, nor anywhere else. The reference price of 1200 € was completely fabricated by the seller to make her believe in a spectacular reduction.
Under French law, this practice constitutes misleading advertising regarding the price and the existence of a promotional advantage. The professional faces criminal sanctions, and Marie can request the cancellation of the sale and a refund of her 600 € for dol (fraud/deception that vitiated her consent).
Example: John, a foreign student newly arrived in Paris, rents an 18 m² studio apartment for a monthly rent of 900 €. The online real estate listing explicitly stated: "Quiet studio, newly renovated, equipped with high-quality acoustic double glazing". Once moved in, John finds that the windows are old single glazing and the noise from the adjacent street makes the accommodation almost uninhabitable. Furthermore, the actual surface area measured according to the loi Carrez (French property measurement law) is only 14 m².
Here, the real estate agency and the landlord have published a misleading advertisement regarding the essential characteristics of the property (a surface area of 14 m² instead of 18 m² and non-existent double glazing). John is entitled to report this listing and take legal action to obtain a significant reduction in his 900 € rent or the termination of the lease without penalty.

If you are a victim or witness of misleading advertising, you must act methodically. Here are the 4 key steps to assert your rights in France.
Before taking any steps, you must secure proof of the infraction. Advertisements on the internet or social networks can disappear in a single click.
The French government has set up an extremely effective public utility tool: SignalConso (managed by the DGCCRF — the French Directorate-General for Competition, Consumer Affairs and Prevention of Fraud).
1. Go to the official website or mobile application of SignalConso.
2. Select the category corresponding to your issue (Online purchase, Real estate, Advertising, etc.).
3. Describe the facts and upload your attachments (screenshots, contracts).
4. Choose to forward the report to the professional so they can comply, or send it directly to DGCCRF investigators.
The ARPP (Autorité de Régulation Professionnelle de la Publicité) is the self-regulatory body for advertising in France. Although it is not a court, its Advertising Ethics Jury (Jury de Déontologie Publicitaire or JDP) can be contacted free of charge by any individual. If the jury finds that the advertisement breaches ethical rules, it will publish a public decision and request the immediate withdrawal of the advertising campaign.
If you have suffered direct financial harm:

French legislation is particularly severe toward companies that use misleading commercial practices. Sanctions can be criminal, civil, and administrative.
Sanctions are defined in *Article L. 132-2 of the Code de la consommation***:
To prevent large multinationals from treating these fines as simple operating costs, French law provides that the amount of the fine can be increased proportionally:
Courts can also hand down highly deterrent additional penalties:

The DGCCRF is the "consumer police" in France. Its agents have extensive investigative powers (access to premises, seizure of documents, hearings). Following your reports on SignalConso, the DGCCRF can decide to inspect the company, issue administrative fines, or forward the file to the Procureur de la République if a criminal offense is established.
Yes, absolutely. The law of June 9, 2023, aimed at regulating commercial influence in France, reiterated that influencers are subject to the same rules as other advertisers. If they promote a product by lying about its effects (for example, miracle slimming capsules) or if they hide the commercial nature of their post (misleading omission), they face the same criminal penalties of 2 years in prison and a 300 000 € fine.
Yes. On a civil level, misleading advertising is treated as dol (vitiated consent under *Article 1137 of the Code civil**). You can request the nullity of the sales contract before the Tribunal judiciaire*. If the judge declares the contract null and void, the seller must refund the full amount paid, and you must return the product. You can also claim damages if you prove you suffered distinct harm.
"Greenwashing" consists of a brand using misleading or disproportionate ecological arguments to boost its image or products. Since the Climate and Resilience Law of 2021, greenwashing is explicitly classified as a misleading commercial practice. Companies that display unsubstantiated claims like "carbon neutral" or "100% ecological" risk a fine that can be increased to 80% of the expenses incurred for the misleading advertisement.
