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 defense 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 offenses) call for early designation of specialist criminal defense 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 offenses) where flight risk is high.
