Misleading Advertising in Spain: How to Report It as an Expat

🇪🇸 Read the original in Spanish

Have you ever bought a product online attracted by spectacular features that later turned out to be false, or signed up for a phone plan with a price promised "forever" that went up after a few months? In Spain, misleading advertising is not just a commercial disappointment, but a systematic legal infringement that violates the most basic rights of consumers. Faced with these abusive practices, the Spanish legal system offers powerful tools so that citizens and foreign residents can defend themselves, demand compliance with what was promised, or request a refund of their money. In this detailed guide, we explain, step-by-step and with legal rigor, how to identify misleading advertising and how to successfully report it to the competent authorities.

What is legally considered misleading advertising in Spain?

In order to file a complaint, the first step is to understand what conduct is considered unlawful under Spanish regulations. Misleading advertising is that which, in any way (including its presentation), deceives or is likely to deceive its recipients, potentially affecting their economic behavior, or silences fundamental facts about the goods, activities, or services when such omission induces error.

The Spanish regulatory framework is highly protective of the consumer and relies mainly on three legislative pillars:

1. *The Ley General para la Defensa de los Consumidores y Usuarios (General Law for the Defense of Consumers and Users - Royal Legislative Decree 1/2007, of November 16): In its Article 61, it establishes a fundamental principle in consumer law: the offer, promotion, and advertising of products or services are enforceable by the consumer, even if they do not expressly appear in the contract concluded*. This means that the advertising brochure, the television commercial, or the screenshot of the website have contractual value.
2. *The Ley de Competencia Desleal (Unfair Competition Law - Law 3/1991, of January 10): Specifically defines in its Article 5* what is considered a misleading omission and unfair practices towards consumers.
3. *The Ley de Servicios de la Sociedad de la Información y de Comercio Electrónico (LSSI - Law on Information Society Services and Electronic Commerce - Law 34/2002, of July 11):* Regulates commercial communications by electronic means (emails, SMS, banners, social networks), requiring that advertising be clearly identifiable as such and that the advertiser be easily recognizable.

Common types of advertising deception

• Deception regarding the price: Hiding fees, mandatory taxes (such as IVA - Value Added Tax), or management fees to make the price appear lower.
• Deception regarding characteristics: Attributing therapeutic, technical, or performance properties to the product that it does not possess.
• Bait advertising: Offering a product at an extremely low price without having a reasonable stock to meet the expected demand, with the sole purpose of attracting customers to the store so they buy other, more expensive products.
• Omission of relevant information: Hiding minimum term commitments (permanencia) or usage limitations of a service in unreadable "fine print".

Practical examples: The economic impact of deception

To understand how these laws apply in real life, we analyze two common scenarios with concrete figures.

Example 1: The hidden surcharge in a subscription service

Juan decides to sign up for a fiber optic internet connection plan attracted by an advertisement on social networks promising: "High-speed fiber for only 19.99 € per month forever".

Upon receiving the first bill, the amount rises to 34.99 €. When complaining, the telephone company informs him that the 19.99 € did not include the "line fee" (cuota de línea), which amounts to 15 € per month, a detail that only appeared in a hidden link within the general terms and conditions of the website.

• Legal solution: According to Article 60 of the Ley General para la Defensa de los Consumidores y Usuarios, the offered prices must include all mandatory taxes and fees. Juan has the right to demand that the advertised price of 19.99 € per month be maintained or to terminate the contract without any penalty, recovering the difference overcharged (15 € for each billed month).

Example 2: The second-hand car with false features

María buys a second-hand vehicle from a professional dealership for 12,000 €. The printed advertisement and the dealership's website highlighted that the vehicle had the "DGT ECO Environmental Label" (Etiqueta Ambiental ECO de la DGT) and a certified combined fuel consumption of 4 liters per 100 km.

After the purchase, upon receiving the physical documentation of the vehicle, María discovers that the real label is "C" (green) and that the actual certified consumption on the technical specifications sheet is 6.5 liters. The difference in the market value of the car and the annual fuel expenditure represents an estimated economic loss of 1,800 € over the useful life of the car.

• Legal solution: Under Article 61 of RDL 1/2007, the advertised features are mandatory. María can demand a reduction in the purchase price proportional to the real value of the delivered car, or the termination of the purchase contract due to breach of contract (returning the car and recovering the 12,000 €).

How to report misleading advertising: Practical step-by-step procedures

If you have been a victim of advertising deception, do not sit idly by. Follow this organized protocol to assert your rights:

Step 1: Gather and secure evidence (Crucial)

The burden of proof rests, to a large extent, on the person reporting. Before the advertiser modifies the website or removes the poster, you must save all physical or digital media:

• Full screenshots (showing the URL, date, and system time).
• Use of digital certification tools for web content (such as Wayback Machine or digital website signing services) so they have full evidentiary validity.
• Physical brochures, catalogs, emails, or WhatsApp messages.
• Invoices, contracts, and bank statements proving the payment made.

Step 2: File a prior complaint with the company

Before resorting to administrative or judicial channels, the law requires attempting an amicable solution.

1. Send a written complaint to the company's customer service department.
2. Use a medium that provides proof of receipt (such as a burofax — a secure certified fax service — with acknowledgment of receipt and text certification, or certified email).
3. In the letter, clearly state what you want (compliance with the original offer, refund of the overcharged money, or termination of the contract) and give them a period of 14 business days to respond.

Step 3: Go to the Municipal Consumer Information Office (OMIC)

If the company does not respond within 30 calendar days (the legal limit established for resolving consumer complaints) or if their response is negative:

1. Go to the OMIC (Oficina Municipal de Información al Consumidor / Municipal Consumer Information Office) of your town hall or to the Dirección General de Consumo (Directorate General for Consumer Affairs) of your Autonomous Community.
2. Submit an official complaint form (hoja de reclamaciones) attaching all the evidence gathered in Step 1.
3. The administration will initiate a mediation phase. If the company is registered with the Sistema Arbitral de Consumo (Consumer Arbitration System), an arbitration can take place, which will end with an arbitration award (laudo arbitral) that is binding and has the same value as a court ruling.

Step 4: Report to Autocontrol

If the advertising company is a member of Autocontrol (an independent advertising self-regulation association in Spain to which major brands and advertising agencies belong):

• You can file a free complaint through their website.
• The Advertising Jury (Jurado de la Publicidad) will resolve within an average period of 14 days whether the advertising violates the Code of Advertising Conduct, urging the company to withdraw or rectify the advertisement.

Step 5: Judicial proceedings (Verbal Trial without a lawyer for low amounts)

If mediation does not work and the amount claimed is less than 2,000 €, you can file a verbal trial lawsuit (juicio verbal) in the Courts of First Instance (Juzgados de Primera Instancia) of your place of residence.

• Advantage: It is not mandatory to appear with a lawyer (abogado) or court representative (procurador), making the process free of charge regarding professional fees.
• You must fill out a standardized verbal trial petition form detailing the facts and providing proof of the misleading advertising.

Deadlines, amounts, and key figures you should know

In the field of consumer law, times and amounts are decisive. Here are the key figures you must memorize:

• 14 calendar days: The general withdrawal period (derecho de desistimiento) you have for online purchases or purchases made outside of commercial establishments, without needing to justify the reason (except for exceptions such as personalized or unsealed products).
• 30 calendar days: The maximum period that companies in Spain have to officially answer a consumer complaint.
• 2,000 €: The economic limit to file a lawsuit through a verbal trial without the need to hire a lawyer or court representative.
• 5 years: The general statute of limitations to demand compliance with contractual obligations derived from misleading advertising (according to Article 1964 of the Código Civil / Civil Code).
• Up to 1,000,000 €: The financial penalties that consumer authorities can impose on companies for very serious infractions regarding misleading advertising and unfair terms, according to the latest reforms of the Ley General de Consumidores y Usuarios.

Mistakes to avoid when reporting

Making mistakes during the complaint process can cause you to lose the opportunity to recover your money. Avoid the following:

• Not saving the advertising proof in time: Thinking that the seller's website will always be available. Companies modify their landing pages and offers quickly as soon as they detect complaints. Without proof of the original advertisement, your claim will not succeed.
• Letting legal deadlines pass: Waiting months to claim an incorrect charge or deception. Although the contractual statute of limitations is broad, immediacy in claiming reinforces the truthfulness of your position before the courts or consumer authorities.
• Confusing an administrative complaint with a claim for money: An administrative complaint (denuncia) before Consumer Affairs seeks to have the company fined for its bad practices, but it does not always guarantee that your money will be returned to you directly. To recover your money, you must expressly request a Consumer Arbitration (Arbitraje de Consumo) or go to court (vía judicial).
• Accepting verbal agreements without written support: If the company offers you compensation over the phone (such as a discount on future bills), demand that they send it to you detailed by email. Words do not serve as proof of a compensation agreement.

Frequently Asked Questions (FAQ)

What happens if the misleading advertising comes from a foreign website?

If the online store is based within the European Union, you can channel your claim through the European Consumer Centre in Spain (CEC), which handles cross-border claims free of charge. If the company is outside the EU (for example, in China or the US), the application of Spanish regulations is highly complex and the enforcement of any resolution is almost impossible in practice.

Can I report an advertisement if I have not bought the product?

Yes. Misleading advertising is an administrative offense and an act of unfair competition in itself. You can file a complaint with the Dirección General de Consumo of your Autonomous Community or with Autocontrol to have the advertisement withdrawn and the company sanctioned, in order to protect the general interest of consumers, even if you have not suffered direct financial harm.

Does the fine print of a contract invalidate what the advertisement said?

No. Article 61 of the Ley General de Consumidores y Usuarios is categorical: the content of the advertising is always enforceable, unless the final contract contains terms that are more beneficial to the consumer. The fine print cannot contradict or unexpectedly cancel the main offer of the advertisement; doing so is considered an abusive clause and is null and void (nula de pleno derecho).

What is the difference between a grievance, a claim, and a complaint?

A grievance (queja) expresses a user's dissatisfaction with a poor service without any financial claim. A claim (reclamación) seeks direct compensation, a refund, or contract termination. A complaint (denuncia) informs the public administration of a legal infraction so that it can investigate and, if applicable, financially sanction the offending company to prevent it from continuing to deceive other users.

Summary

• Advertising is contractually binding: Everything promised in brochures, websites, or promotional videos has the force of law between the parties and must be fulfilled.
• Ironclad digital proof: Save screenshots, brochures, and certified emails before starting any complaint procedure.
• Mandatory amicable route: Always attempt a prior written claim with the customer service department, granting a period of 14 days.
• Consumer Arbitration: This is the free, fast, and effective way to resolve consumer disputes without having to go to court.
• Verbal Trial up to 2,000 €: If the amicable route fails, you can sue in court for free and without the need for a lawyer or court representative.
