8 Things to Sort Out Before an International Extradition Case Begins
Someone calls our support line at 11 p.m. because a police officer in a foreign country has just told them there is a warrant with their name on it, and they want to know what to do in the next hour. Almost every one of those calls follows the same pattern: the person has already lost days, sometimes weeks, to confusion that could have been avoided with a short list of tasks done in the right order. If you are trying to understand A useful overview of international extradition rules, the most valuable thing you can do is prepare before the formal process starts, not after the paperwork lands on your doorstep. Extradition is a treaty-based process, not a single law, so what applies to you depends on which two countries are involved, what the alleged offence is, and what stage the request has reached. The eight points below are the ones that repeatedly decide whether a case stays manageable or spirals into months of avoidable detention.
1. Confirm What Kind of Request Is Actually Pending
People often use “extradition” as a catch-all term, but the documents behind it vary enormously. A foreign arrest warrant, an Interpol Red Notice, a diplomatic note, and a formal extradition request are four different things with four different legal consequences. A Red Notice is a request to locate and provisionally arrest a person, not a court order, and it can exist for years without any formal extradition request ever being filed. A formal request, by contrast, is a diplomatic document that must satisfy the requirements of a specific treaty before a domestic court can even consider it.
Before anything else, get a clear answer to one question: what exactly has been issued, by which authority, and on what date? Ask for the reference number, the issuing country, and the offence named. If you are told only that “there is a notice,” that is not enough to plan a defence. The distinction matters because the remedies are different. Challenging a Red Notice through the Commission for the Control of Interpol’s Files, for example, is a separate track from contesting an extradition request in a national court, and confusing the two wastes the most valuable time you have.
2. Map the Treaty Relationship Between the Two Countries
Extradition only happens where there is a legal basis for it. That basis is usually a bilateral treaty, a multilateral convention, or in some cases domestic legislation that allows cooperation with designated partners. Two countries can have a treaty that covers only certain offences, or a treaty that has been superseded by a newer agreement, or no treaty at all but a working arrangement through an international tribunal.
This is why the same facts can produce completely different outcomes depending on geography. A request between two states with a long-standing treaty and a strong political relationship moves quickly. A request involving a state with a narrow treaty, or one where the offence is not listed in the schedule, may fail at the first legal hurdle. Practitioners routinely check whether the conduct would be a crime in both countries, whether it carries a minimum penalty threshold, and whether the treaty excludes political or military offences. None of that can be assessed without first identifying the exact instrument that applies.
3. Check Dual Criminality and the Minimum Penalty Threshold
Dual criminality is the principle that the conduct must be a serious crime in both the requesting and the requested country. It sounds simple, but it is one of the most contested areas in extradition litigation. A behaviour that is criminal in one jurisdiction may be lawful or only an administrative offence in another. Courts do not always require the offences to have identical names; many apply a conduct-based test, asking whether the underlying acts would be punishable in both places.
Most treaties also set a minimum penalty, commonly one year or more of imprisonment, for the offence to qualify. This threshold filters out minor matters and is often the first thing a defence lawyer checks. If the alleged conduct carries a maximum penalty below the threshold in either country, the request may be legally defective from the outset. Gathering the sentencing ranges, the charging document, and any local case law on comparable offences is therefore a priority, not an afterthought.
4. Understand Bars and Exceptions That Can Stop a Request
Even where a treaty exists and the offence qualifies, a request can be refused. The most common bars include political offence exceptions, military offence exceptions, nationality of the requested person, ne bis in idem (double jeopardy), statutes of limitation, and humanitarian grounds such as age or serious illness. Some countries refuse to extradite their own nationals and instead prosecute them domestically; others permit it under conditions.
Human rights arguments have also become a significant barrier. Courts increasingly assess whether the requesting state can guarantee a fair trial, whether prison conditions meet minimum standards, and whether the person faces a real risk of torture or inhuman treatment. These arguments require evidence, not assertion, so collecting country-of-origin reports, medical records, and expert testimony early makes a material difference. A bar that is raised late is often a bar that is rejected on procedural grounds alone.
5. Organise Identity, Travel, and Residence Records
One of the least glamorous but most decisive tasks is assembling a clean documentary record of who you are, where you have been, and where you legally reside. Extradition proceedings turn on identity more often than people expect. A name that matches a foreign database entry, a date of birth discrepancy, or a passport number reused by someone else can trigger a provisional arrest that takes months to untangle.
Keep certified copies of your passport, national identity documents, residence permits, visas, and entry and exit stamps. If you have changed your name or hold dual nationality, document the sequence of events. If you have been resident in the requested country for years, evidence of stable employment, family ties, and property can support arguments against detention and against extradition itself. These are also the documents that make a bail application credible rather than aspirational.
6. Know the Local Procedure and Your Rights at Each Stage
Extradition procedure differs sharply from country to country. In some systems a judge conducts a committal hearing focused on whether the formal requirements are met; in others the executive branch plays a larger role; in others a specialised court handles the entire matter. What is broadly consistent is that you have the right to legal representation, the right to be informed of the charges, the right to challenge the request, and the right to appeal certain decisions.
Timelines are equally variable. Provisional arrest is often followed by a strict deadline, frequently forty to sixty days, within which the requesting state must submit its full documentation. Missing that deadline can lead to release. Consular assistance may be available depending on your nationality, and it is worth contacting your embassy early even though consular officials cannot provide legal advice. Knowing which stage you are at, and what the next deadline is, prevents the single most common mistake: assuming there is more time than there is.
7. Prepare Financial, Employment, and Family Evidence for Detention Hearings
If there is a risk of arrest, the practical question becomes whether you can remain at liberty while the case proceeds. Courts considering bail or conditional release weigh flight risk, community ties, the seriousness of the alleged offence, and the strength of the requesting state’s case. A well-prepared file containing employment contracts, tax records, bank statements, lease agreements, and letters from family members can shift that assessment.
It also helps to have a proposed residence address, a surrender plan, and a clear statement of any medical conditions requiring treatment. Judges are not persuaded by vague assurances; they are persuaded by concrete arrangements. This is one area where preparation is almost entirely within your control, and it is frequently the difference between waiting for a hearing at home and waiting for it in custody.
8. Choose Counsel Who Works on Cross-Border Requests Regularly
Extradition sits at the intersection of criminal law, public international law, human rights law, and diplomatic practice. A lawyer who is excellent in domestic criminal defence may have never handled a treaty-based request. The practical test is straightforward: ask how many extradition or Interpol matters they have handled in the last two years, whether they have appeared before the relevant court, and whether they have experience with the specific requesting country.
You should also confirm who will handle the Interpol side of the matter if a notice is involved, because that work often runs in parallel with the court case and on a different timetable. A coordinated team can challenge a notice, respond to a formal request, and prepare a release application without duplicating effort or contradicting itself. If the matter involves more than one jurisdiction, ask how the firms communicate and who holds the master timeline. Clarity on that point at the start saves considerable confusion later.
Frequently Asked Questions
Does every country have an extradition treaty with every other country?
No. Extradition depends on a specific legal basis, which may be a bilateral treaty, a multilateral convention, or domestic legislation. Some pairs of countries have no arrangement at all, which is why the answer to “can I be extradited from here to there” always begins with identifying the exact instrument that applies to those two states.
How long does an extradition case usually take?
It varies widely. A straightforward matter may be resolved in a few months, while contested cases involving appeals, human rights arguments, or parallel Interpol challenges can take several years. The provisional arrest stage often carries strict deadlines of around forty to sixty days for the requesting state to file its full documentation.
Can a Red Notice alone lead to my extradition?
Not by itself. A Red Notice is a request to locate and provisionally arrest a person, and it is not a court order or a final decision. Extradition requires a formal request that satisfies the applicable treaty and is approved through the requested country’s legal process. A notice can, however, lead to detention while that process unfolds.
What happens if I am a national of the country where I am found?
Many countries refuse to extradite their own nationals and instead prosecute them domestically for the alleged conduct. Others allow extradition of nationals under certain conditions. The outcome depends on the constitution, the treaty, and the specific offence, so this should be checked at the very beginning of a case.
Should I speak to foreign investigators before consulting a lawyer?
Statements made under pressure can be used later, and the legal effect of an interview differs depending on where it occurs and who conducts it. It is generally prudent to seek legal advice before answering substantive questions about the alleged conduct, while still complying with lawful identification requirements.
