Arrested in Spain: A Complete Guide for Foreign Nationals (2026)

Every year, foreign nationals are detained or arrested in Spain — whether as tourists, expats, or business visitors. The experience is daunting, especially when you don't speak the language or understand the legal system. As English-speaking criminal defence lawyers in Spain, we explain below what you need to know.

Your Rights When Arrested in Spain

Spanish law (Art. 520 LECrim) grants you specific rights from the moment of detention, regardless of your nationality:

• Right to silence: You do NOT have to answer any questions. Use this right. Say nothing until your lawyer arrives.
• Right to a lawyer: Free designation of counsel is a constitutional right: you may choose your own lawyer at any time, or request a duty lawyer (abogado de oficio) if you do not designate one.
• Right to an interpreter: If you don't speak Spanish, the police MUST provide a sworn interpreter. Do not sign anything in Spanish without understanding it.
• Right to consular notification: The police must inform your embassy or consulate if you request it.
• Right to a phone call: You can make one phone call to inform someone of your detention.
• Right to medical attention: If you're injured or feel unwell, you have the right to see a doctor.

The 72-Hour Detention Timeline

In Spain, police can hold you for up to 72 hours without a judge's order (Art. 17.2 Spanish Constitution). Here's what happens:

• Hour 0-24: Police processing, fingerprinting, and initial questioning. Your lawyer should be present for any statement.
• Hour 24-48: Police decide whether to release you or present you to a judge (Juzgado de Guardia).
• Hour 48-72: If presented to a judge, the court hearing determines whether to release you, impose bail, or order pre-trial detention (prisión provisional).

For drug trafficking and terrorism, detention can be extended to 5 days with judicial authorization.

5 Critical Mistakes Foreign Nationals Make

1. Talking without a lawyer: The biggest mistake. Anything you say becomes evidence. Police may be friendly, but they are gathering information.
2. Signing documents in Spanish: Never sign a document you can't read. Demand a translation or ask your lawyer to review it.
3. Fleeing Spain before trial: If you leave Spain while under investigation, the court may issue a European Arrest Warrant. This follows you across all EU countries.
4. Underestimating the technical complexity of the charge: Serious charges (money laundering, fraud, sexual offences) call for early designation of specialist criminal defence counsel.
5. Not contacting your embassy: Your consulate can provide a list of local lawyers, contact your family, and ensure you receive fair treatment.

Bail and Conditional Release

After the initial court hearing, the judge will decide your situation:

• Release without charges: You're free to go. The investigation may continue, but you're not detained.
• Release on bail (fianza): Common for foreigners. The judge sets a financial guarantee to ensure you attend trial. Amounts vary from €1,000 to €100,000+.
• Release with conditions: Passport surrender, periodic court appearances, or travel restrictions.
• Pre-trial detention (prisión provisional): Reserved for serious crimes (murder, major drug trafficking, violent offences) where flight risk is high.

Can I Return to Spain After Being Arrested?

Whether you can safely come back to Spain after an arrest depends on the current status of your case, not on the arrest itself. Three questions determine the answer:

• Is the case still open? If the proceedings were closed or provisionally shelved, or you were acquitted, there is normally no obstacle to returning. If the investigation or trial is still pending, travelling without checking first is risky.
• Were precautionary measures imposed? If the judge ordered you to appear periodically before the court, to surrender your passport, or prohibited you from leaving Spain, breaching those conditions can lead to a new arrest and even pre-trial detention.
• Is there an outstanding warrant? If you left Spain while proceedings were pending, the court may have issued a search-and-arrest order (requisitoria) or a European Arrest Warrant, which can be executed at the border the moment you re-enter.

Before booking any trip, have a Spanish criminal lawyer check the status of the case directly with the court. That check can confirm whether the case has been closed, whether any warrant is active and, where appropriate, allow your lawyer to arrange a voluntary court appearance instead of an airport arrest.

Arrested in Spain for Assault

Bar fights and street altercations are among the most frequent reasons foreign visitors are arrested in Spain. Physical assaults are prosecuted as offences of bodily harm (lesiones) under Article 147 CP:

• Injury requiring medical or surgical treatment beyond a first medical assistance: prison of 3 months to 3 years or a fine of 6 to 12 months (Art. 147.1 CP).
• Lesser injuries not requiring such treatment: fine of 1 to 3 months (Art. 147.2 CP).
• Hitting or mistreating someone without causing injury: fine of 1 to 2 months (Art. 147.3 CP).

The last two categories are only prosecuted if the injured person files a complaint. The medical report describing the injuries and the treatment they required is often the decisive piece of evidence, since it determines which of these categories applies. If this is your situation, our guide to the likely sentence for a first-offence assault in Spain explains how these cases are typically resolved.

The maximum seventy-two-hour period for the judge to convert the arrest into pre-trial detention or set the person free, once the detainee has been handed over, is governed by Article 497 of the Spanish Criminal Procedure Law.
