How to File a Police Report in Spain: A Step-by-Step Guide

🇪🇸 Read the original in Spanish

Finding yourself in a situation where you are a victim or a witness of a crime generates, in addition to obvious emotional stress, a sea of legal doubts. Knowing how to react, who to turn to, and what documents to present is essential for the machinery of Spanish justice to begin working in your favor. In this practical guide prepared by the legal team at AbogadoAI, we explain in detail and step-by-step how to file a denuncia (police report/criminal complaint) in Spain in accordance with current legislation, ensuring that your rights are fully protected from the very first moment.

What is a denuncia and how does it differ from a querella?

Before starting the process, it is crucial to understand the legal nature of a denuncia. In the Spanish legal system, a denuncia is the act of bringing to the attention of the authority (police, judicial, or prosecutorial) the commission of acts that bear the characteristics of a crime.

There is common confusion between the terms "denuncia" and "querella" (formal court complaint). It is useful to clarify their fundamental differences:

• *The denuncia** is a general civic duty (with exceptions) and a right of the victim. It does not require the intervention of a lawyer or a procurador* (court representative), it is free of charge, and the complainant does not automatically become a party to the judicial process (although they can join as a party later).
• *The querella, on the other hand, is a formal declaration by which criminal action is initiated and the complainant constitutes themselves as a prosecuting party in the process. It strictly requires the signature of an abogado (lawyer) and representation by a procurador, in addition to the posting of a fianza* (bail/security deposit) in certain scenarios.

The regulatory framework: What does the law say?

The right and obligation to report a crime are mainly regulated by the Ley de Enjuiciamiento Criminal (LECrim) (Criminal Procedure Act).

• Article 259 of the LECrim establishes the general duty to report: "Anyone who witnesses the perpetration of any public crime is obliged to immediately bring it to the attention of the nearest examining judge, justice of the peace, district or territorial judge, or Prosecutor to the place where they are located".
• Meanwhile, Article 265 of the LECrim determines that denuncias may be made in writing or orally, in person or through an agent with special power of attorney.

Who is obliged to report a crime and who is exempt?

Although the general rule is the mandatory nature of reporting any criminal act of which one has knowledge, the Criminal Procedure Act itself establishes important exceptions based on family relationships or professional secrecy.

Persons exempt from the obligation to report:

According to Article 261 of the LECrim, the following are not obliged to file a report:

1. The spouse of the offender (or person bound by a similar relationship of affectivity).
2. Ascendants and descendants related by blood or affinity to the offender (parents, children, grandparents, grandchildren).
3. Siblings by blood or half-siblings, and collateral relatives up to the second degree.

Likewise, Article 263 of the LECrim exempts lawyers and procuradores from this obligation regarding disclosures made to them by their clients, thereby safeguarding professional secrecy.

How to file a denuncia in Spain: Step-by-step

If you have decided to take the step to report a criminal act, we recommend following this structured procedure to ensure the viability of your claim.

Step 1: Identify the type of crime

Crimes in the Spanish Penal Code (Código Penal - Organic Law 10/1995) are mainly divided into:

• *Public crimes (delitos públicos):* These can be prosecuted ex officio by the authorities (for example, theft, homicide, or fraud). Anyone who witnesses them can and must report them.
• *Semi-public or semi-private crimes (delitos semipúblicos or semiprivados):* These require a prior complaint from the aggrieved person or their legal representative for justice to take action (for example, harassment, threats, or crimes of discovery and revelation of secrets).
• *Private crimes (delitos privados): Only prosecutable via a querella* filed by the offended party (slander and libel).

Step 2: Gather the evidence

The effectiveness of a denuncia depends largely on the evidence you provide. Before going to the police station or the court, collect:

• Identity documents (DNI, NIE (foreigner identification number), or Passport).
• Photographs or videos of the damage or the event.
• Text messages, emails, or screenshots of social networks (it is advisable to digitally certify this evidence if possible).
• Medical reports or injury reports (parte de lesiones) if physical or psychological violence has occurred.
• Contact details of potential witnesses who witnessed the events.

Step 3: Choose the presentation channel

In Spain, you have three main avenues to file a denuncia:

1. *Before the Law Enforcement Agencies (Fuerzas y Cuerpos de Seguridad): You can go to the Policía Nacional (National Police), the Guardia Civil (Civil Guard), or the Regional Police forces (Mossos d'Esquadra in Catalonia, Ertzaintza in the Basque Country, Policía Foral* in Navarre). This is the fastest and most common route.
2. *Before the Duty Court (Juzgado de Guardia): You can present the denuncia directly in writing to the Deanery of the Courts (Decanato de los Juzgados) of the place where the events occurred or at the Juzgado de Guardia*.
3. *Before the Prosecutor's Office (Fiscalía): The State Attorney General's Office (Fiscalía General del Estado*) or the Territorial Prosecutor's Offices also receive complaints, especially regarding economic crimes, corruption, or those affecting minors.

Note for foreign residents: If you do not speak Spanish or the co-official languages, you have the right to request a free interpreter during the process of filing the denuncia, as set out in the Estatuto de la Víctima del Delito (Statute of the Victim of Crime).

Step 4: Drafting or declaring the statement

If you report in person (orally), a police officer will draft an acta (official record) containing your statement. You must narrate the facts chronologically, clearly, and precisely, without unnecessary subjective evaluations.

If you report in writing (via the Court), the document must contain:

• Full identification of the complainant.
• Identification of the accused (if known) or, failing that, a physical description or details that help locate them.
• A detailed account of the facts (date, time, place).
• Signature of the complainant.

Step 5: Signing and obtaining your copy

Once the denuncia has been drafted, read it carefully. Make sure that everything written down matches exactly what you have declared. If you detect any error, ask them to correct it before signing. Once signed, you have the right to receive a stamped copy completely free of charge. Keep this document, as it is your legal proof of having initiated the process.

Practical examples with real figures

To better understand how the reporting process operates and its economic and criminal consequences, we analyze two everyday situations:

Example 1: Fraud in the purchase of a second-hand vehicle

Let's imagine that Carlos buys a second-hand car from a private individual for a price of €4,500. After making the payment and receiving the vehicle, Carlos discovers that the odometer has been tampered with to hide the fact that the car has 150,000 kilometers more than indicated, which reduces its real value to barely €1,200.

• Action: Carlos must file a denuncia for an alleged crime of fraud (estafa) under Article 248 and following of the Código Penal.
• Process: He goes to the Policía Nacional station with the purchase contract, proof of the bank transfer of €4,500, and a mechanical expert report certifying the odometer manipulation.
• Legal consequence: Since the amount exceeds €400, we are not dealing with a minor offense (delito leve), but rather a less serious crime of fraud, punishable by prison sentences of 6 months to 3 years. Carlos will request the return of the economic difference or the termination of the contract plus compensation for damages in the criminal proceedings.

Example 2: Damage to third-party property (vandalism)

María owns a commercial premises. One night, vandals break her shop window and spray graffiti on the facade. The repair of the glass and the cleaning of the paint amounts, according to the glazier's and painter's quotes, to €350.

• Action: María files a denuncia providing photographs of the damage and the detailed quote of €350.
• Process: She submits the report online through the police's virtual office and later goes to sign it physically, providing the proforma invoices.
• Legal consequence: Since the amount of damage is less than €400, the acts are classified as a minor crime of damage (delito leve de daños) under Article 263.1, second paragraph of the Código Penal. This crime is punishable by a fine of 1 to 3 months, in addition to the civil obligation to indemnify María for the €350 cost of the repair.

Mistakes you must avoid when filing a denuncia

Making mistakes during the filing of a denuncia can delay the process, cause the case to be archived, or, in the worst-case scenario, lead to criminal consequences for the complainant themselves. Always avoid the following:

• Filing a false report or simulating a crime: Reporting events that have not occurred or attributing a crime to a person knowing they are innocent is a serious crime classified in *Article 456 of the Código Penal. It can lead to prison sentences of 6 months to 2 years and fines of 12 to 24 months*. A common and dangerous example is reporting the theft of a mobile phone that was actually lost in order to claim insurance compensation.
• Omitting contact details or key evidence: Filing a report without providing phone numbers, emails of those involved, or without attaching the documents that prove the fraud makes the police investigation extremely difficult and usually ends in a provisional archiving of the case due to lack of a known perpetrator.
• Delaying the filing of the report: Although crimes prescribe over long periods, the passage of time weakens evidence. Security camera recordings are usually deleted automatically after 30 days due to data protection regulations, and physical or biological traces disappear quickly. Always report as soon as possible.
• Not requesting a stamped copy: Leaving the police station or court without your copy of the denuncia will prevent you from carrying out essential procedures, such as claiming from insurance, justifying an absence from work, or requesting protection orders in cases of violence or harassment.

Frequently Asked Questions (FAQ)

Can I file a denuncia completely anonymously?

Not through ordinary, common channels. The LECrim requires the identification of the complainant to prevent false reports and protect legal certainty. However, there are specific citizen collaboration channels (such as the Policía Nacional hotlines/inboxes for drug trafficking or human trafficking) where information can be provided confidentially. Likewise, the Prosecutor's Office and the Labor Inspectorate (Inspección de Trabajo) have specific mailboxes where the identity of the informant is preserved.

How much does it cost to file a denuncia in Spain?

Filing a denuncia in Spain is 100% free of charge. It does not require the payment of any court fee, nor is it mandatory to hire a lawyer or procurador to file it before the police or the duty court. Costs would only appear in later stages of the judicial process if you decide to appear with your own legal defense team as a private prosecution (acusación particular), although if you lack sufficient financial resources, you have the right to request free legal aid (abogado de oficio).

Can I withdraw a denuncia once it has been filed?

It depends on the type of crime. If it is a public crime (such as a robbery or an assault), the denuncia cannot be "withdrawn" as such. Even if you express your desire not to proceed, the Prosecutor's Office and the Court have the obligation to move forward with the investigation and trial ex officio. Only in private or semi-public crimes (such as slander or certain minor damage crimes) can the forgiveness of the offended party or the withdrawal of the accusation bring the judicial procedure to an end.

What are the time limits for reporting a crime?

The time limit to report a crime coincides with the statute of limitations of the crime, regulated in *Article 131 of the Código Penal***. This period varies substantially depending on the severity of the offense:

• Minor offenses (delitos leves) prescribe after 6 months.
• Crimes punishable by prison sentences of less than 5 years prescribe after 5 years.
• The most serious crimes can prescribe after 10, 15, or 20 years (homicide, for example, prescribes after 20 years).
• Crimes against humanity and genocide never prescribe.

In summary

• The denuncia is a formal and free act through which the authorities are informed of the existence of a possible criminal event.
• Any natural person, whether of Spanish or foreign nationality, has the right (and sometimes the duty) to report.
• It can be filed in person before the Police, the Civil Guard, the Duty Court, or the Prosecutor's Office, always providing a DNI, NIE, or passport.
• It is essential to provide all available evidence (documents, photos, witnesses) at the time of the report to prevent the case from being archived.
• Reporting false facts or simulating being the victim of a crime is a serious criminal conduct that carries prison sentences and heavy fines.
