Online Defamation in Spain: Legal Action Against Insult and Slander (Injurias y Calumnias)
A false comment on a forum. A review that invents things that never happened. An anonymous profile accusing your company of something it didn't do. When something like this shows up online, the first reaction is almost always the same: "Can I sue over this?" The answer is usually yes, but the how, and above all the why, determine whether that legal action actually protects your reputation or turns into a drain on time and money with no practical result.
The Spanish legal system offers two distinct paths against online defamation: the criminal route (vía penal), through the offenses of injurias (insult) and calumnias (slander/false accusation of a crime) set out in the Criminal Code (Código Penal), and the civil route (vía civil), through Organic Law 1/1982 on the civil protection of the right to honor, personal and family privacy, and one's own image. They are not interchangeable alternatives: they have different requirements, different deadlines, different burdens of proof, and different outcomes. Choosing the wrong path, or pursuing both without a clear strategy, is one of the most common sources of frustration for people who come under attack online.
In this guide, drawn from Élite Reputación's experience managing reputational crises alongside law firms that specialize in this area, we explain the real difference between injuria and calumnia, when each route makes sense, how to document evidence so it holds up in court, how an anonymous author gets identified, what a burofax actually achieves before litigation, what timelines and costs are reasonable to expect, and, most importantly for the majority of cases, when legal action is not the most effective route and should be combined with a hands-on reputation management strategy.
Important legal notice
This article is for general information and educational purposes only. It does not constitute individualized legal advice and is not a substitute for a lawyer's assessment of your specific case. Every online defamation situation has its own circumstances (the exact content, the channel through which it spread, the author's identity, the harm caused) that only a professional can properly evaluate. At Élite Reputación we work with law firms specializing in the right to honor and offenses against reputation, and we always recommend a specific legal consultation before taking any action.
This is not the same as the right to be forgotten
People often confuse this topic with the right to be forgotten, but they are completely different remedies. The right to be forgotten is an administrative data protection remedy (GDPR/LOPDGDD) used to delist from Google information that is old but true and no longer relevant. What we cover here is something else: false or defamatory content presented as fact that damages your honor, where the remedy runs through the Criminal Code or Organic Law 1/1982, not through a Google form. If your problem is that Google keeps showing old but true, non-defamatory information, this isn't the path for you: you need the right to be forgotten.
2. Injuria and calumnia: what the Spanish Criminal Code actually says
The Spanish Criminal Code devotes Title XI of Book II (roughly Articles 205 to 216) to "offenses against honor" (delitos contra el honor), under two clearly distinct offenses: calumnia and injuria. Confusing them is the most common mistake among people considering action, and it has practical consequences: each one is proven, argued, and prosecuted differently.
Calumnia (Art. 205 CP)
This means accusing someone of a specific crime while knowing the accusation is false, or with reckless disregard for the truth. Example: posting that a person "scammed" their clients or "committed tax fraud" with no real basis. It is the more serious of the two offenses.
Injuria (Art. 208 CP)
This is any act or statement that damages a person's dignity, harming their reputation or undermining their self-esteem, without going as far as accusing them of a specific crime. Example: insults, disparaging remarks, or humiliating statements about someone's integrity or professional competence.
The element that decides everything: intent
Both injuria and calumnia require intent to damage someone's honor (what legal scholars call animus iniuriandi). A good-faith mistake, harsh but honest criticism, or a poorly worded opinion is not, by itself, a crime. Spanish courts are especially careful to distinguish an intent to harm from the mere expression of disagreement, however uncomfortable it may be.
Other relevant nuances worth knowing before deciding how to proceed:
- Injuria is only a crime when, by its nature, effects, and circumstances, it is considered serious in the eyes of the public; minor insults generally don't rise to the level of a criminal offense
- The exceptio veritatis (Art. 210 CP) allows someone accused of calumnia to avoid punishment if they prove the fact they alleged, subject to statutory exceptions; for injuria, this "proof of truth" defense doesn't work the same way, because what is protected is dignity, not the truthfulness of a specific fact
- Dissemination with publicity (online, on social media, or through the press) is treated as an aggravating factor (Art. 211 CP) compared with an insult made in private
- Since the 2015 reform of the Criminal Code, most injurias and calumnias are punished only with a fine, not prison, except in highly aggravated cases
3. The criminal route: when it makes sense to file a complaint or a private prosecution
The criminal route seeks a conviction: for a judge to rule that an offense of injurias or calumnias was committed and to impose a penalty, usually a fine. Its primary aim is not financial compensation (although that can be claimed at the same time) or the immediate removal of the content: its goal is to punish the conduct.
3.1. A procedural detail that surprises many people: filing a police report isn't enough
Unlike other crimes, injurias and calumnias are, with some exceptions, private offenses (delitos privados): Article 215 of the Criminal Code provides that they can only be prosecuted through a querella (a formal criminal complaint filed as a private prosecution) brought by the offended person or their legal representative. This means the public prosecutor doesn't act on its own initiative as it would with a robbery or an assault; the victim must drive the proceedings with the help of a lawyer and, in many cases, a procurador (court representative) as well. The main exception is when the injurias or calumnias target a public official, authority, or officer in connection with the performance of their duties, in which case the Public Prosecutor's Office (Ministerio Fiscal) may also act.
3.2. What the criminal route requires in practice
- Establishing who authored the content (identification, see below)
- Proving the element of intent: that there was a will to damage someone's honor, not just disagreement or criticism
- Meeting the criminal standard of proof, which is stricter than in civil proceedings ("beyond a reasonable doubt")
- Accepting that the proceedings may drag on due to the usual caseload of investigating courts (juzgados de instrucción)
When the criminal route is usually the best fit
When the content accuses you of a specific, false criminal act (a clear case of calumnia), when there is an evident intent to cause harm in a repeated and organized way, or when the top priority is a public sanction that sends a message to the author. In these cases, a criminal conviction also carries strong evidentiary weight for later claiming civil damages.
4. The civil route: Organic Law 1/1982 and protecting the right to honor
Organic Law 1/1982 of May 5 on the civil protection of the right to honor, personal and family privacy, and one's own image (Ley Orgánica 1/1982) offers a different path and, in practice, one used more often than the criminal route in many online defamation cases, especially when the goal is getting the content removed and receiving financial compensation rather than a criminal conviction.
This law starts from a key principle: honor, privacy, and one's own image are fundamental rights (Article 18.1 of the Spanish Constitution) that can be protected through civil action against any unlawful interference (intromisión ilegítima), without any crime having been committed. Article 7 of LO 1/1982 sets out what counts as unlawful interference, including disclosing facts that affect a person's reputation or attributing qualities, situations, or conduct that diminish their standing in their own esteem.
4.1. Practical advantages of the civil route
Presumption of harm
Article 9.3 of LO 1/1982 states that harm is always presumed once unlawful interference has been proven, which makes it significantly easier to claim damages than under the criminal route.
A more attainable standard of proof
The civil route is governed by the preponderance-of-the-evidence standard, which is less demanding than the "beyond a reasonable doubt" standard in criminal proceedings.
Priority, fast-track proceedings
Because it involves protecting a fundamental right, the claim can be brought through the special procedure for the protection of fundamental rights, which moves faster than ordinary proceedings.
Concrete remedies
The judge can order the interference to stop, require publication of the judgment, and award compensation proportional to the moral and financial harm caused.
4.2. A deadline you need to keep firmly in mind
Article 9.5 of LO 1/1982 provides that the civil protection action expires four years after the moment the entitled party could have brought it. Unlike a statute of limitations (prescripción), this expiration period (caducidad) cannot be tolled or interrupted: if you let the deadline pass, you lose the right to sue. That's one more reason not to delay the decision to act once you've spotted defamatory content.
4.3. Comparison: criminal route vs. civil route
| Aspect | Criminal route (injurias / calumnias) | Civil route (LO 1/1982) |
|---|---|---|
| Legal basis | Criminal Code, Arts. 205-216 | Organic Law 1/1982 |
| Main objective | Criminal penalty for the author (fine) | End of the interference and compensation |
| How it starts | Querella by the offended party (private offense) | Civil lawsuit (demanda) |
| Standard of proof | Very demanding (reasonable doubt) | More attainable (preponderance of the evidence) |
| Presumption of harm | No; the damage must be proven | Yes, it is presumed (Art. 9.3 LO 1/1982) |
| Deadline to act | Criminal statute of limitations (varies by severity) | Expires after 4 years (Art. 9.5) |
| Approximate duration | 6-18 months or more to judgment | 6-12 months via the priority procedure |
| Approximate cost | Lawyer (and procurador depending on the court) | Lawyer, procurador, and possible court fees |
Can you pursue both routes at the same time?
In certain cases, yes, but with important procedural nuances: if criminal proceedings are already open over the same facts, the civil case is usually stayed on grounds of criminal preliminary ruling (prejudicialidad penal) until the criminal case is resolved. This is precisely one of the strategic decisions where the judgment of a specialized lawyer makes the difference between resolving the case in months or dragging it out unnecessarily.
5. When legal action is NOT worth it: opinion vs. statement of fact
This is probably the most important section of the entire article, because it's where we see the most frustrated expectations in practice. Not everything that bothers you is defamation, and Spanish courts, following the case law of the Constitutional Court (Tribunal Constitucional), firmly protect freedom of expression, even when it's uncomfortable, harsh, or exaggerated.
The key distinction: freedom of expression vs. freedom of information
The Constitutional Court distinguishes between value judgments or opinions (protected by freedom of expression, Art. 20.1.a of the Spanish Constitution) and statements of specific fact (subject to the truthfulness requirement of freedom of information, Art. 20.1.d of the Spanish Constitution). A negative opinion, or harsh or even sarcastic criticism of a service, product, or professional conduct is, as a general rule, protected, even if it "offends, shocks, or disturbs," as constitutional case law has repeatedly put it. What isn't protected is asserting as true a fact that is false, knowing it's false or without making even minimal efforts to verify it, with the aim of causing harm.
In practice, this translates into very concrete examples:
Usually protected
"I found the service very slow and I don't recommend it," "I think this company charges a lot for what it offers," "My experience was bad." These are subjective assessments, even if they sting.
Potentially defamatory
"This company scams its customers," "The owner has a record for fraud," "They sell stolen goods." These are statements of specific, verifiable fact and, if false, actionable.
Before considering any legal action, it's worth honestly asking yourself these questions:
- Does the content assert a specific, false fact, or does it express a subjective opinion or assessment?
- If it asserts a fact, is it really false, or do you simply not like that it's been made public?
- Is there a legitimate public or professional interest behind the criticism (for example, a customer's real experience)?
- Does the tone, however harsh, cross the line into gratuitous insult with no factual basis at all?
The risk of litigating against a legitimate opinion
Taking legal action against a negative but honest review rarely succeeds, and it can also trigger the so-called "Streisand effect": the attempt to silence criticism draws even more attention to it and to the dispute itself. In these cases, the effective path isn't the courtroom but reputational crisis management: responding transparently, improving whatever needs improving, and building up positive content around the brand.
6. How to document evidence properly from minute one
Defamatory content online can be edited or deleted, or the profile that posted it can vanish within hours, especially if the author realizes a claim is being made against them. That's why documenting the evidence should be the very first thing you do, even before deciding which legal route to take.
6.1. Levels of evidence, from basic to robust
- Full-page screenshot
Include the full URL in view, the system date and time, and the context (the author's profile, the complete comment thread). A cropped or undated screenshot has little evidentiary value. - Saving the full page and its source code
Tools such as web archiving services (Wayback Machine, archive.today) or printing the full page to PDF strengthen the evidence compared with a simple image. - Notarial certificate of facts (acta notarial de constancia de hechos)
This is the strongest level of evidence: a notary certifies that, on a specific date and time, they accessed a URL and verified specific content. It carries far more evidentiary weight than your own screenshot and is practically essential if the case is going to end up in court. - Witnesses
If other people saw the content before it was deleted or modified, their testimony can strengthen the evidence, especially when notarial certification wasn't possible in time. - Technical trail (IP addresses, metadata)
When they can be accessed (for example, comments on your own website or on channels you manage), IP addresses and metadata can help identify the author, although interpreting them technically usually requires a digital forensics expert.
Why a notarial certificate makes the difference
A screenshot can easily be challenged in court on grounds of tampering. A notarial certificate, as a public document backed by a notary's attestation (fe pública), shifts the burden of doubt onto whoever challenges it. If the case has any real weight, and even more so if you plan to go the criminal route, the cost of a notarial certificate (usually between €100 and €300 depending on the notary and complexity) is an investment that almost always pays off.
- Preserve the evidence the same day you spot it; don't wait until you've decided what to do
- Also document how far it has spread (views, shares, comments) if that's relevant to the reputational damage
- Keep copies of any prior communication with the author or the platform
- Don't respond publicly on impulse: any response you make is also on the record and can be used against you or in your favor
7. Identifying anonymous authors: the hardest step in practice
A large share of defamatory content online is posted from anonymous profiles, fake accounts, or pseudonyms, precisely to make any claim harder. Identifying who's behind it isn't always possible, but it isn't impossible either: there are specific legal avenues for trying.
7.1. Court-ordered identification measures
Once a querella has been admitted or proceedings have been opened, the lawyer can ask the court to formally order the platform (social network, forum, digital media outlet) or the internet service provider to hand over the registration data associated with the account: the connection IP address, registration email, and linked phone number. These identification measures (diligencias de identificación) are, in most cases, the only effective mechanism for reaching the author when the platform won't cooperate voluntarily.
7.2. Direct court requests to platforms
Major platforms (Meta, Google, X, TikTok) usually require a formal court order before handing over user data, precisely to protect themselves from legal liability. In practice, this means you first have to open judicial proceedings (a report, a querella, or a lawsuit) and request the corresponding measure within them; they rarely hand over this data in response to a simple private request.
International complexity
Many platforms have their European headquarters outside Spain (Ireland, for example), which may require international judicial cooperation mechanisms and lengthens response times.
Digital forensics expertise
An expert can trace technical patterns, metadata, or similarities in writing style and behavior that, while not providing 100% identification, strengthen solid indications of authorship.
When identification fails
If it ultimately isn't possible to identify the author, you can still ask the platform or host to remove the content, and in some cases take action against the intermediary if it fails to meet its takedown obligations under Spain's Information Society Services Act (LSSI).
"In most of the cases we handle with our legal partners, identifying the author is the real bottleneck in the process. It's not an automatic formality: it requires procedural strategy from the very first filing, because a mistake in how the measure is requested can mean losing your only chance to obtain that data."
8. The burofax and the formal pre-litigation demand: why it's almost always the first step
Before going to court, in the vast majority of cases it makes sense to send a burofax (Spain's certified, legally verifiable letter service) with proof of delivery and, if possible, certification of its contents, addressed to the author of the content or to the platform hosting it. It isn't just a formality: it serves several concrete legal and practical purposes.
A verifiable date for the claim
It creates reliable proof of when the recipient was made aware of the problem, which matters both for deadlines and for assessing any subsequent good or bad faith.
"Actual knowledge" for intermediaries
With hosts and platforms, formally notifying them of unlawful content can trigger their duty to act diligently (Art. 16 LSSI) so they don't become liable themselves for third-party content.
A chance to resolve it without going to court
Many individuals and companies voluntarily remove the content when they receive a formal demand with legal counsel behind it, sparing both sides a lengthy proceeding.
Proof of procedural good faith
If the case ends up in court, having first tried an out-of-court solution is usually viewed favorably and can influence the award of legal costs.
What a good pre-litigation demand should include
Clear identification of the content and its exact URL, the specific reason it is considered unlawful (citing the applicable law), a reasonable deadline for voluntary removal (usually 48-72 hours), an express warning of the legal action that will be taken if the demand is ignored, and the contact details of the lawyer representing the claimant. A burofax drafted without legal judgment, full of generic threats, loses much of its deterrent effect and its later procedural value.
9. Realistic timelines and costs: what to expect before you start
One of the biggest sources of frustration in these processes is unrealistic expectations about timing. A legal action, whether won or lost, almost never "erases" content overnight. These are approximate ranges, always subject to the complexity of each case and the workload of the relevant court:
| Stage | Approximate timeline | Approximate cost |
|---|---|---|
| Notarial certificate of facts | 1-3 days | €100 - €300 |
| Burofax with pre-litigation demand | Typical response within 48-72h of delivery | €20 - €40 to send, plus drafting fees |
| Identification measures (if needed) | Weeks to several months | Included in the proceedings' fees |
| Civil proceedings (LO 1/1982) | 6-12 months at first instance (priority procedure) | Varies depending on fees, procurador, and court fees |
| Criminal proceedings (querella) | 6-18 months or more to a final judgment | Varies, generally higher than civil |
| Appeals (apelación, casación) | Additional months for each level | Additional fees for each level |
A favorable judgment is not a delete button
Even with a judgment in your favor, enforcement (actually getting the content removed and the damages paid) can take additional time, and in some cases the content has already been replicated on other sites beyond the direct reach of that judgment. That's why we insist that legal action is one piece of the plan, not the whole plan.
10. Combining legal action with hands-on reputation management
This is where, in our experience with Élite Reputación clients, the real difference between a well-managed case and a poorly managed one is made. Court proceedings, even when handled with the utmost diligence by a good firm, take months. In the meantime, the content remains visible, keeps showing up on Google when someone searches for your name or your company's, and keeps causing reputational damage day after day.
The most effective strategy works on three fronts in parallel, not one after the other:
Legal front
A burofax and, where appropriate, a querella or civil lawsuit, handled by lawyers who specialize in the right to honor. The goal is a formal halt, a penalty, and/or compensation.
Technical and SEO front
While the legal process moves forward, reverse SEO reduces the visibility of negative content in search results, minimizing the damage while the underlying issue is resolved.
Communication front
A measured, consistent, and timely public response, as part of a reputational crisis management strategy, keeps the defamatory content itself from filling the information vacuum.
It's also worth remembering that there are content removal mechanisms that don't depend on winning a lawsuit: direct requests to the platform, social networks' dedicated reporting forms, or direct negotiation with whoever published the content. You can review all of these options in detail in our guide on how to remove negative content from Google, which is the perfect complement to the legal route described in this article.
"The most common mistake we see is waiting for the court case to end before starting to work on reputation. By the time there's a judgment, months of unnecessary exposure have gone by. The legal route and reputation management should start on the same day, not one after the other."
11. Conclusions and action plan
Online defamation has a legal remedy in Spain, but that remedy only works well when it's applied with sound judgment: distinguishing injuria from calumnia, choosing between the criminal and civil routes based on your real objective, documenting the evidence from minute one, and being honest about whether what was published is actually a legitimate opinion, however harsh, or a false statement of fact.
- Calumnia falsely accuses someone of a crime; injuria damages dignity without alleging a specific crime. Both require intent to cause harm
- The criminal route seeks a penalty and requires a querella by the offended party; the civil route (LO 1/1982) seeks an end to the interference and compensation, with a more attainable standard of proof
- Opinions and criticism, however harsh, are protected by freedom of expression; only false statements of fact are actionable
- Evidence must be secured immediately: screenshots showing the date and URL, and notarial certificates in cases of real weight
- Identifying an anonymous author almost always requires opening judicial proceedings first
- A prior burofax is usually the most cost-effective step: fast, inexpensive, and with legal and deterrent value
- No legal process erases content immediately: it must be combined with reverse SEO and communication management
Recommended action plan
- Document immediately
Screenshots with the URL and date visible, and consider a notarial certificate if the case has real weight. - Assess opinion vs. fact
Before anything else, honestly determine whether there's a false statement of fact or "just" an uncomfortable opinion. - Consult a specialized lawyer
To decide between the criminal route, the civil route, or both, and to assess whether the case truly has legs. - Send a burofax with a pre-litigation demand
In most cases, this is the step that solves the problem without having to litigate. - If there's no response, start the appropriate proceedings
A querella or civil lawsuit, with a request for identification measures if the author is anonymous. - Work on reverse SEO and communication in parallel
Don't wait for the judgment to minimize the visible damage while the process moves forward.
At Élite Reputación we don't replace a lawyer, but we coordinate with law firms specializing in the right to honor so that the legal strategy and the reputation strategy move forward together, not separately. If you're dealing with defamatory content online, the first thing we do is an honest analysis: whether your case has real legal legs, whether one route is better than the other, and what can be done in parallel to reduce the damage starting now. In many cases, our own service to remove online defamation and harmful content gets the defamatory content taken down without having to wait for the court proceedings to end.
