What is extradition?
Extradition is a legal procedure whereby one State requests another to surrender a person to stand trial or serve a sentence for crimes recognised in both countries, in accordance with international treaties. This process is governed by strict legal and human rights guarantees, such as the principle of double criminality, and has safeguards in place to prevent abuse or undue persecution. Having a solicitor who specialises in extradition is key to protecting the rights of the person concerned and ensuring compliance with international regulations.
Extradition treaties affecting Spain
Spain has an extensive network of extradition treaties that enable international judicial cooperation in criminal matters. These agreements, both bilateral and multilateral, regulate the surrender of persons accused or convicted of crimes, ensuring respect for fundamental rights.
- European Convention on Extradition (1957): Facilitates extradition between Council of Europe member states under a common legal framework.
- Extradition agreement between Spain and the United Kingdom (post-Brexit): It maintains criminal judicial cooperation between both countries after Brexit, in force since April 2021.
- European Arrest Warrant (EAW): European Union mechanism that replaces traditional extradition, speeding up the transfer of persons between Member States.
- Bilateral treaties with non-European countries: Spain has extradition agreements with countries such as the United States, Canada, Australia and various Latin American states.
- United Nations international agreements: Spain participates in international treaties that include provisions on extradition, such as the Convention against Transnational Organised Crime.
Our role as extradition criminal solicitors
Active extradition
Active extradition occurs when Spain requests another State to surrender a person to be tried or serve a sentence in Spanish territory. In these cases, lawyers are involved in preparing and processing the request, providing evidence, representing clients in international proceedings and advising victims who request the extradition of the perpetrator to Spain.
Passive extradition
Passive extradition occurs when Spain receives a request from another country to hand over a person who is in its territory. The solicitor’s work focuses on defending the person sought, analysing the legality of the request, protecting their fundamental rights and, where appropriate, negotiating legal alternatives or preparing for a possible risk of extradition.

Questions about defence in international extradition cases
Which countries have extradition agreements with Spain?
Spain has bilateral treaties and multilateral agreements on extradition with numerous countries around the world. Below is a list grouped by geographical region:
- European countries: Spain has extradition agreements with practically all European countries, including the United Kingdom. This is particularly the case through the European Convention on Extradition and the European Arrest Warrant (EAW), applicable between European Union countries.
- Central and South America: where treaties have been signed with most Latin American countries, such as Argentina, Mexico, Colombia, Chile, Peru, Venezuela, Ecuador, Brazil, Bolivia, Uruguay, Paraguay, Panama, Costa Rica, and the Dominican Republic, among others.
- African countries: Spain has agreements with certain countries, such as Morocco, Algeria, Egypt, Tunisia, South Africa, and Cape Verde.
- Asia and the Middle East: Spain also cooperates on extradition matters with countries such as China, India, Japan, Israel, Turkey, Lebanon, the Philippines, South Korea, Saudi Arabia and Pakistan.
- Rest of the world: there are also treaties with key countries such as the United States, Australia, Canada, and New Zealand.
How long does an extradition process take?
The duration of an extradition process can vary considerably depending on the specific case, but in general terms, the time frame usually ranges from several months to over a year. The factors that influence the total length of the procedure are:
- Case complexity: If there are several charges, multiple jurisdictions, or incomplete documentation, the process is prolonged.
- Requesting country: The type of agreement in place between Spain and the country requesting extradition (bilateral, European, multilateral) determines the speed of the procedure.
- Legal remedies sought: The filing of appeals or constitutional protection remedies before the Constitutional Court may significantly extend the duration.
- Collaboration between states: The smoother the judicial cooperation between the countries involved, the faster the process tends to move forward.
Can an international extradition order be avoided?
Yes, in certain cases it is possible to avoid extradition if it can be proven that the surrender would violate fundamental rights, such as the risk of torture or the lack of judicial guarantees in the requesting country.
Each situation requires individual analysis. One of our extradition solicitors can study the case and present the necessary legal arguments to oppose the surrender.
In what cases can extradition be refused?
An international extradition order may be denied if certain legal circumstances apply. Among the most common are the statute of limitations for the crime, the absence of double jeopardy (the act is not a crime in both countries), or the political motivation behind the request.
It may also be refused if the defendant is a Spanish national, if they have already been tried for the same offences in Spain or another country (principle of non bis in idem), or if the documentation submitted is incomplete or incorrect. The legal defence must assess all these elements in order to effectively oppose the surrender.
What happens if the person being sued has dual nationality?
In this case, one of the countries may refuse to extradite her if she is a national of that country, as many states—including Spain—do not extradite their own citizens. In that case, they may offer to have her serve her sentence in their territory instead of handing her over.
However, the decision will depend on the applicable treaty and the circumstances of the case. Dual nationality does not automatically guarantee that extradition will be denied, so it is essential to seek specialised legal advice.
What should I do if I receive an extradition notice?
If you receive an order to be extradited to another country, the most important thing is to act quickly. Do not try to deal with the process on your own or sign anything without advice. Extradition is a complex procedure with very strict deadlines and serious consequences if not handled correctly from the outset.
