Extradition from Spain: How the Procedure Works and What an Extradition Lawyer Does

Which route applies: extradition, European arrest warrant, or another surrender agreement?

Start with the requesting country, not the person's passport or the city of arrest. A request from a country outside the EU ordinarily goes through Ley 4/1985, de Extradición Pasiva, subject to the relevant treaty. In contrast, a warrant issued by an EU Member State is governed in Spain by Ley 23/2014, de reconocimiento mutuo de resoluciones penales en la Unión Europea, implementing Framework Decision 2002/584/JHA as amended. Its faster judicial timetable and consent rules are different. An INTERPOL Red Notice is an international police alert, not a judgment and not itself an international arrest warrant; Spanish law determines whether an arrest and further proceedings follow it.

Spain ratified the 1957 Convention on 7 May 1982; it entered into force for Spain on 5 August 1982. Its treaty-office record contains Spanish reservations, including protection against extradition to exceptional courts and a reservation on time-barred proceedings, and Spain's 2022 communications. Do not assume every protocol or a foreign state's declaration applies automatically: counsel should check the treaty status and reservations of both states on the request date. In a bilateral relationship with a different treaty, review that text as well. A request from Switzerland, Turkey or the United States is not an EU EAW merely because a European arrest has occurred.

Who handles a case after the 2025 Spanish court reform?

Spain has nationwide specialist jurisdiction for these proceedings. Historically, legislation and older commentary referred to the Juzgados Centrales de Instrucción in Madrid. Under Organic Law 1/2025, the Tribunal Central de Instancia was constituted on 31 December 2025; its Sección de Instrucción handles incoming extradition files and EAW execution under the amended Organic Law of the Judiciary, article 95. Earlier case papers and some unchanged provisions of Ley 4/1985 and Ley 23/2014 still use the former judicial labels. This is an institutional change, not a transfer of the case to the provincial court of arrest.

In non-EU extradition the Ministerio de Justicia receives or processes formal requests; the Consejo de Ministros decides whether proceedings should continue to the judicial phase. A judge of the Sección de Instrucción of the Tribunal Central de Instancia (the current successor to the Juzgados Centrales de Instrucción) deals with initial appearance, custody and referral. If the requested person consents under article 12 and there is no legal obstacle, the judge may grant the request without the full contested Chamber hearing; consent must therefore be discussed with a lawyer before it is recorded. In opposed cases, the Criminal Chamber of the Audiencia Nacional decides judicial admissibility wherever the person was arrested. A favourable court ruling does not compel the Government to surrender; a final unfavourable court ruling prevents surrender under article 6 of Ley 4/1985. For an EAW, a judge of the Sección de Instrucción of the Tribunal Central de Instancia exercises the statutory surrender jurisdiction, with appeals to the Criminal Chamber where Ley 23/2014 allows them. The EAW statute still uses some of the former court labels; the current institutional name follows the 2025 reform. Check the designation on the live court order, not only the name printed in older statutes.

Police detention in Barcelona, Málaga province or Madrid therefore does not mean an ordinary provincial criminal court makes the final extradition determination. For local transfers and first-contact logistics use the Barcelona arrest guide, Marbella arrest guide, or Madrid court guide.

Non-EU extradition: the sequence from request to handover

Article 7 of Ley 4/1985 requires a formal request via diplomatic channels or directly between the justice ministers. It must include the relevant judgment or judicial detention instrument, facts, identifying information and legal provisions, with an official Spanish translation under the domestic statute. Under Spain’s reservation to article 23 of the 1957 Convention, treaty requests may instead be accompanied by translations into Spanish, French or English; the applicable treaty must be checked before treating a translation as defective. Extradition can be sought for prosecution or enforcement of a sentence. Under article 2, the ordinary threshold is an offence punishable under both systems by a maximum term of at least one year, or enforcement of a custodial sentence of at least four months; treaty terms can change the analysis. These are eligibility thresholds, not predictions that an individual request will succeed.

These statutory periods attach to different events. In particular, the three days for the court order run after the extradition hearing, not after arrest; the Government's fifteen days run after the ministry proposal, not after the family's first enquiry. Missing documents, treaty rules or proceedings in Spain may affect the real calendar. Ask counsel to construct a dated chronology from the arrest report, receipt stamps, appearance record, notifications and hearing listing.

Custody: why the 40-day and 80-day figures do not mean automatic release in every case

Where detention starts on an urgent provisional-arrest request, Ley 4/1985 articles 8(2) and 10 require provisional custody to be lifted if the requesting state does not submit a proper formal extradition request within 40 days of the urgent arrest. If the formal request arrives within those 40 days, the preliminary period may be extended by a further 40 days so the Ministry and Government can act. If proceedings instead start on receipt of a formal extradition request, article 10 sets a different trigger: custody must be lifted if the judge has not received the Government’s decision to continue the judicial phase within 40 days from receipt of that formal request. These are preliminary-stage rules, not a universal 80-day cap on the whole case.

Article 10 sends maximum-custody questions not specifically regulated by Ley 4/1985 to the Ley de Enjuiciamiento Criminal (Criminal Procedure Act). Article 504 sets offence-dependent limits for the categories of pre-trial detention it covers: normally one year where the offence carries a custodial penalty of three years or less, or two years where the penalty exceeds three years. If the statutory conditions are met, one reasoned extension may be authorised, up to six months or two years respectively; a separate rule may apply after conviction where the sentence is appealed. These figures are not an automatic cap in every extradition file: the legal basis for detention, the alleged offence, any extension order and the applicable treaty must be checked against the actual court file. Do not calculate the whole case from the 40-day preliminary rule alone.

The central judge may order release with measures under article 8(3), including passport withdrawal, reporting obligations, travel restrictions, home supervision or security/bail. Such measures are fact-specific; there is no automatic right to bail and no basis for claiming that a foreign passport alone requires prison. Residence records, identifiable accommodation, family links, medical information and a credible attendance plan may help the judge assess risk. Release does not cancel the underlying extradition request, and article 8 contemplates renewed detention if the request arrives later.

European arrest warrant: a separate judicial clock

For an EAW, an arrested adult must be brought before a judge of the Sección de Instrucción of the Tribunal Central de Instancia within 72 hours of arrest under article 50 of Ley 23/2014; the statute still names the former Juez Central de Instrucción. For a minor aged 14 or older, article 50 specifies 24 hours before the specialised juvenile jurisdiction, now the Sección de Menores of the Tribunal Central de Instancia. Article 51 requires a judicial hearing within 72 hours of being brought before the judge. The person receives information about the warrant and rights, including assistance from a lawyer in the issuing Member State who can assist the Spanish defence lawyer.

At the hearing the person is asked whether they irrevocably consent to surrender. The record separately states any waiver of the speciality principle (a restriction on subsequent prosecution for other earlier offences). Do not confuse agreement to surrender with a separate speciality waiver. With valid consent and no obstacle, the central judge can order surrender with no ordinary appeal against that order under article 51(4). Without consent, the judge schedules a further hearing within three days; an order must then be made within ten days of that hearing, and article 51(8) provides a direct appeal to the Criminal Chamber of the Audiencia Nacional.

Article 54 sets the main decision deadlines: with consent, the judicial decision must be made within 10 days of the hearing; without consent, a final decision is due within 60 days of arrest, with a reasoned extension of up to 30 days where justified and notification to the issuing authority. These are decision deadlines, not an automatic release rule. The judge separately decides on custody or proportionate measures under article 53; a Spanish national or resident sought for prosecution may be eligible for a return-to-serve condition under article 55(2), and pending Spanish proceedings can delay delivery under article 56. Detailed refusal grounds and case-specific evidence are outside this procedural overview.

Nationality, consent and speciality change the decision

For ordinary non-EU extradition, article 3(1) of Ley 4/1985 generally rules out extradition of Spanish nationals, assessed by the extradition court at the time of its decision, while expressly excluding nationality obtained fraudulently to defeat extradition. Dual nationality requires real documents and an individual legal analysis; do not assume merely carrying two passports settles the question. Where the refusal concerns a Spanish national, article 3(2) envisages referral to Spanish prosecution authorities if the requesting state asks, so refusal does not necessarily end potential criminal accountability. By contrast, a Spanish national can be subject to an EU EAW: the nationality rules and possible return-to-serve conditions are different.

An EAW requires a separate distinction. If it seeks prosecution, article 55(2) allows surrender to be made conditional, after hearing the person, on return to Spain to serve a custodial sentence later imposed. If it seeks enforcement of an existing custodial sentence, article 48(2)(b) allows the Spanish court to refuse surrender where the person is Spanish or resident in Spain, unless they consent to serving the sentence in the issuing state; where this ground is applied, the sentence is to be served in Spain. The warrant’s purpose and the person’s nationality and residence status must therefore be checked.

For non-EU extradition, article 12 deals with the person's consent before the judge; article 21 protects speciality by requiring an additional authorisation procedure to prosecute earlier, different facts after extradition, subject to its conditions. In EAW matters, the consent and speciality questions are expressly recorded separately under article 51. Before signing, request a translated explanation of what will and will not be contested or waived. Family agreement or the desire to shorten detention cannot replace the person's informed decision.

What an extradition lawyer should do at each decision point

• After arrest: identify whether the authority is acting on a formal extradition request, an urgent request, an EAW or police data; obtain the custody record, judicial reference and interpreter; check the correct 24-hour or 72-hour route.
• Before the custody hearing: prepare identity and residence evidence, health needs, proportional alternatives to prison and any documents that explain why a flight-risk assumption is inaccurate.
• During ministerial screening: obtain the requesting state's judicial instrument, offence description, applicable treaty and translations; establish when Spain received each item and whether supplementary material restarted a statutory clock.
• Before the court hearing: distinguish facts about legal eligibility from a defence to the criminal charge abroad. Spanish extradition proceedings do not ordinarily retry the foreign merits; article 14 limits evidence to treaty and statutory extradition conditions.
• At surrender and afterwards: review the scope of the decision, any conditions, speciality, the transfer timetable and coordination with a lawyer in the requesting state.

A useful family file contains the detainee's exact name and date of birth; citizenship documents; arrest date, time and place; court reference; any request or warrant; criminal judgment if one exists; residence and family documents; medical evidence if relevant; and counsel contact details. Save the dates on each document. Do not forward sensitive records to unverified intermediaries or publish allegations online. If the person cannot explain the procedure in Spanish, ask counsel to secure appropriate interpretation and a comprehensible explanation before consent is recorded.

A practical example: a detention following a Red Notice

Hypothetical situation: a Georgian citizen living in Barcelona is arrested on a Red Notice issued following a non-EU prosecution. The family assumes Spain must send the person abroad within forty days. That assumption is unsafe. The defence must first establish whether this was an urgent request under article 8 of Ley 4/1985 and on what date Spain received a formal demand. If the case continues, a central judge and the Audiencia Nacional have different roles, and the Government's final decision may still be needed. The family's immediate job is to provide identity, lawful residence and reliable contact information to the Spanish lawyer while the lawyer checks the request and the detention timetable. If the requesting state instead issued an EU EAW, a different set of authorities, hearings and deadlines would apply.

What happens after the court rules, and where are challenges brought?

For non-EU extradition, article 12(3) provides a recurso de reforma against the central judge’s initial order, and article 15(2) provides a recurso de súplica against the Audiencia Nacional Chamber’s admissibility order, decided by the full Criminal Chamber. For an EAW, a non-consent surrender order may be appealed directly to the Sala de lo Penal; the specified consent order has no ordinary appeal. These routes are distinct, and a challenge should not be assumed to suspend surrender. Detailed refusal grounds and exceptional remedies belong in the separate Spain refusal-and-appeals guide. Immigration removal is a separate legal process, not a substitute for extradition.
