What to Do If You Are Arrested in Spain: Your Rights

🇪🇸 Read the original in Spanish

Being deprived of your liberty is one of the most stressful and disorienting situations anyone can experience in Spain, whether they are a national citizen or a foreign resident. In these moments of maximum tension, the difference between protecting your legal future or severely complicating your situation lies in knowing your exact constitutional and procedural rights. Spanish legislation is highly protective of individual rights, but these safeguards are only fully effective if you know how and when to activate them. Below, we analyze in depth the legal framework, the practical steps you must take if you are arrested, and how to act to guarantee an effective criminal defense from the very first second.

The Legal Framework of Arrest in Spain

An arrest is not a pre-emptive conviction, but rather an exceptional and provisional precautionary measure. Its sole purpose is to bring the suspect before a judge or to carry out the initial, indispensable inquiries to clarify an alleged crime.

Our fundamental law, the Spanish Constitution of 1978, consecrates the right to liberty and security in its Article 17, establishing the unbreakable limits of preventive detention. In turn, the detailed development of these rights and the procedure to be followed are regulated in the Ley de Enjuiciamiento Criminal (LECrim - Criminal Procedure Act), specifically in its Article 520, which was deeply reformed to transpose European directives on procedural guarantees.

The Código Penal (Criminal Code - Organic Law 10/1995) also plays an indirect but crucial role: it defines which conducts constitute a crime and, in its Article 530, typifies the crime of "illegal detention" committed by a public official, punishing any authority or officer who, during a criminal investigation, prolongs a citizen's detention in violation of legal deadlines and requirements.

Your Constitutional Rights: Article 520 of the LECrim

The moment officers of the Fuerzas y Cuerpos de Seguridad del Estado (State Security Forces and Bodies, which include the National Police, Civil Guard, or Regional and Local Police) inform you that you are under arrest, the catalog of rights under Article 520 of the LECrim is automatically activated. These rights must be read to you immediately, in simple and accessible language, and in writing (the famous "rights sheet").

1. Right to Remain Silent

You are not obliged to declare against yourself or to confess guilt. You have the right to:

• Not answer any of the questions asked by the police officers.
• State that you will only testify before the Juez de Instrucción (Investigating Judge) at the duty court.
• Answer only the questions asked by your own defense lawyer.

2. Right to Appoint a Lawyer

This is the pillar of your defense. You have the right to designate a lawyer of your own choice. If you do not designate one or do not have the financial resources, the State will assign you a court-appointed lawyer from the local Colegio de Abogados (Bar Association).

• The lawyer has the right to interview you privately before you make any statement at the police station.
• They will be present during all your statements and in any identity parades or lineup procedures you participate in.

3. Right to Have Your Detention Communicated

You have the right to have the telephone or electronic communication of your arrest and your place of custody immediately facilitated to a family member or a person of your choosing. If you are a foreigner, this right includes the mandatory notification to the Consulate of your country of origin.

4. Right to Be Assisted by a Free Interpreter

If you are a foreigner and do not understand or speak Spanish (or the co-official language of the autonomous community), or if you have hearing or speech difficulties, you have the right to the assistance of an interpreter completely free of charge, including for private conversations with your lawyer.

5. Right to Be Examined by a Forensic Doctor

This is a fundamental right to guarantee your physical integrity. You have the right to request the presence of a médico forense (forensic doctor) or, failing that, the medical service of the nearest health center or hospital, to evaluate your state of health and issue a medical report to be attached to the police report.

Legal Deadlines: How Long Can You Be Detained?

Spanish law is extremely strict regarding the duration of deprivation of liberty before being brought before a judge.

• The General Limit: Preventive detention cannot last longer than the time strictly necessary to carry out the inquiries aimed at clarifying the facts. In any case, the absolute maximum limit is 72 hours (3 days). Once this period has elapsed, the police must either release you or place you at the disposal of the judicial authority.
• Exceptional Cases (Terrorism): In cases of terrorism offenses or membership in armed gangs, the 72-hour limit can be extended by an additional 48 hours, always requiring express judicial authorization within the first 48 hours of the arrest.
• Minors: If the detainee is under 18 years old, the general regime of the LECrim regarding ordinary police custody does not apply. They must be placed at the disposal of the Sección de Menores de la Fiscalía (Juvenile Section of the Prosecutor's Office) within a maximum period of 24 hours.

Step-by-Step Guide: What to Do If You Are Arrested

If you find yourself in a situation where you are arrested by the police in Spain, you must follow these steps in an orderly manner to safeguard your physical and legal integrity:

Step 1: Keep Calm and Do Not Show Physical Resistance

Active resistance or physical confrontation with officers can lead to a crime of atentado a la autoridad (assault on authority) or serious resistance (Articles 550 and following of the Criminal Code). This will drastically worsen your legal situation, regardless of whether the initial reason for the arrest was minor or non-existent.

Step 2: Request the Reading of Your Rights and the Information Sheet

Ask to be handed the written declaration of rights. Read it carefully. If you do not understand the language, immediately demand the presence of an interpreter. Do not sign any document if you are not completely sure of its contents or if your lawyer has not yet arrived.

Step 3: Request a Trusted or Court-Appointed Lawyer

Provide the first and last name of the criminal defense lawyer of your choice. If you do not know one, request that the turno de oficio (court-appointed duty lawyer system) be notified. It is a very common mistake to think that asking for a court-appointed lawyer "makes you look guilty"; on the contrary, it is the only way to ensure your rights are not violated at the station.

Step 4: Exercise Your Right to Remain Silent at the Police Station

As a general rule of criminal defense strategy, it is highly recommended to exercise your right not to make a statement to the police. The police report is a preliminary investigation phase. It is preferable to wait for your lawyer to examine the physical and testimonial evidence gathered (accessing the atestado or police report) and, subsequently, testify with full guarantees before the Juez de Instrucción at the duty court.

Step 5: Request a Medical Examination If Deemed Necessary

If you have suffered injuries during the arrest, if you suffer from a chronic illness that requires urgent medication (such as diabetes or heart disease), or if you are suffering from severe anxiety, demand to be seen by a doctor immediately. The medical report is an unquestionable official document.

Practical Examples of Arrest Situations

To better understand how these rights operate in real life, we analyze two everyday scenarios under Spanish legislation:

Example 1: Arrest for DUI and Road Safety

Let us imagine Carlos, who is stopped at a routine checkpoint by the Guardia Civil de Tráfico (Traffic Civil Guard). When taking the breathalyzer test, he shows a result of 0.85 mg/l of exhaled air (the criminal limit is 0.60 mg/l according to Article 379.2 of the Criminal Code).

1. Carlos is arrested for an alleged crime against road safety.
2. He is taken to the station, where his rights are read to him.
3. Carlos decides to request a court-appointed lawyer and exercises his right to remain silent at the police station.
4. Since he has no criminal record and it is a crime that does not require complex investigative steps, the police arrange a juicio rápido (speedy trial). Carlos is released within 6 hours with a summons to appear before the Juzgado de Guardia (Duty Court) the following day, where his lawyer will negotiate, if applicable, a one-third reduction of the driving ban penalty (for example, reducing a proposed 12-month ban to 8 months through a plea agreement).

Example 2: Arrest of a Foreign Resident for Alleged Theft

Suppose the case of Jean, a French citizen residing in Barcelona. He is accused by a department store security guard of stealing electronic devices worth €950 (which exceeds the €400 threshold that differentiates a minor offense of theft from the more serious misdemeanor of theft, according to Article 234.1 of the Criminal Code).

1. The police arrest Jean at 14:00 hours on a Friday.
2. Jean requests a French interpreter and asks for his arrest to be communicated to the French Consulate, as well as to his partner.
3. The court-appointed lawyer arrives at the police station at 17:00 hours. After interviewing Jean in private (with the help of the interpreter), the lawyer advises him not to make a statement to the police.
4. Since Jean has a known address in Spain and there is no imminent risk of flight, on Saturday at 10:00 hours (after 20 hours of detention), Jean is brought before the Juez de Guardia, who decrees his provisional release without fianza (bail/security deposit) pending trial.

Mistakes to Avoid If You Are Arrested

Making mistakes during the first hours of an arrest can lead to irreversible negative consequences throughout the subsequent criminal proceedings. Avoid the following behaviors at all costs:

• Talking about the facts with officers "informally": Anything you say to the police in the patrol car or in the corridors of the station—even if you think it is a friendly or unofficial conversation—can be included in the "spontaneous statements" section of the police report and used against you before the judge.
• Signing statements or records without the physical presence of your lawyer: Never sign any document (neither seizure records, modified rights readings, nor statements) unless your lawyer is present in the room and expressly tells you that you can do so.
• Lying about your identity or showing false documentation: Hiding your real name or showing a fake passport or ID card constitutes an independent crime of document forgery (Article 392 of the Criminal Code) and, furthermore, is the main argument the Prosecutor will use to request your provisional prison sentence due to "flight risk" since you are not fully identified.
• Resisting physically or insulting authority officers: As mentioned, this will transform a potentially minor issue into a serious criminal charge for assault or disobedience, which carries prison sentences of 6 months to 3 years.

The "Habeas Corpus" Procedure: What Is It and When Is It Requested?

Habeas Corpus is a constitutional procedure of extraordinary importance, regulated by Organic Law 6/1984. Its purpose is the immediate judicial presentation of any person who is being illegally detained.

When is a detention considered illegal?

• When the legal requirements to arrest are not met (for example, if there is no evidence of a crime).
• When the maximum detention limits (72 hours in general) are exceeded without being brought before a judge or released.
• When the fundamental rights of the detainee have not been respected (such as systematically denying access to a lawyer or a doctor).

How is it requested?

It can be requested by the detainee themselves, their spouse or common-law partner, their descendants, ancestors, siblings, and, of course, their defense lawyer. The process is extremely simple: a written request (or a verbal statement to the custody officers, who are obliged to process it immediately under pain of criminal sanction) is addressed to the duty Juez de Instrucción. The Judge must order that the detainee be brought before them immediately to present their allegations. The Judge will issue an order within a maximum of 24 hours directing the immediate release, a change in custody conditions, or the continuation of legal detention.

Frequently Asked Questions (FAQ)

Can the police interrogate me at the station without my lawyer present?

No. Under Spanish law, any interrogation or formal statement-taking at police facilities strictly requires—under penalty of absolute nullity of the evidence—the physical presence of your lawyer (whether private or court-appointed). The only things the police can do without your lawyer are identify you and take your standard fingerprints and mugshots.

What is the difference between a court-appointed lawyer and a private lawyer during an arrest?

The only difference lies in the designation: the court-appointed lawyer (abogado de oficio) is randomly assigned by the duty shift of the local Bar Association, while a private lawyer is hired directly by you or your family. Both have exactly the same professional and ethical obligations to defend your interests. If you lack financial resources, the court-appointed lawyer's service will be free; if you have sufficient financial means, the Bar Association may invoice you for their fees later.

Can I refuse to have my fingerprints or photographs taken?

It is not recommended to refuse. Taking fingerprints and photographs (reseña decadactilar y fotográfica) for the identification of persons arrested for serious or less serious crimes is a lawful and mandatory procedure authorized by the LECrim. Violent or persistent opposition to this procedure can be considered a crime of serious disobedience to authority.

What happens if I am arrested in Spain and I am an undocumented foreigner?

If you are arrested for the alleged commission of a crime, the criminal procedure follows exactly the same channels and guarantees as for a Spanish citizen. However, the police will notify the immigration brigade of the arrest. If you have a preferential deportation order or are in an irregular situation, there is a risk that, once your release is decreed in the criminal field, an administrative deportation process will be initiated or executed in accordance with the Ley de Extranjería (Immigration Law). Therefore, having specialized legal defense from the very first minute is doubly crucial.

In Summary

• Preventive detention in Spain has an absolute maximum limit of 72 hours, and must be reduced to the time strictly necessary for the investigations.
• Article 520 of the LECrim guarantees your right to remain silent, not to testify against yourself, and to designate a lawyer of your choice immediately.
• Legal assistance is mandatory for any formal statement; you must never testify or sign documents without your lawyer being present in the room.
• The right to health allows you to demand to be examined by a forensic or emergency doctor to certify your physical and psychological state during custody.
• Habeas Corpus is the immediate constitutional tool to report and resolve arbitrary, illegal detentions, or those exceeding the permitted deadlines.
• Keeping calm, not resisting physically, and exercising your right to remain silent before the police are the three golden rules to protect your procedural future.
