A foreign national facing arrest, police custody, or a criminal investigation in Turkey needs a defense that controls the first 24 hours and protects residence and entry status at the same time. Serka Law Firm defends international clients across the criminal process in Turkey while managing the immigration consequences that a criminal file creates. We act in English and 14 other languages, coordinate with consulates and family abroad, and keep the criminal defense and the deportation risk on one strategy rather than two disconnected files.
What is criminal defense for foreign nationals in Turkey?
Criminal defense for foreign nationals in Turkey is legal representation of a non-citizen suspect or defendant through police custody, prosecution, trial, and appeal under the Turkish Code of Criminal Procedure No. 5271 and the Turkish Penal Code No. 5237. For foreigners, the defense also covers two rights that decide the early outcome: the right to a defense lawyer and the right to a free, competent interpreter at every stage where a statement is taken.
A criminal accusation against a foreigner rarely stays inside the criminal courtroom. A conviction, and sometimes the investigation alone, can trigger a deportation decision and an entry ban under Law No. 6458 on Foreigners and International Protection. Treating the two as one connected matter is the core of competent foreign-national defense.
What should I do in the first hours after arrest?
In the first hours after arrest in Turkey, say nothing beyond your identity, refuse to sign any statement you have not read in a language you understand, and request a lawyer and an interpreter immediately. Police custody (gözaltı) is time-limited under the Code of Criminal Procedure No. 5271; a statement signed without counsel or accurate translation can shape the entire case against you.
The right to remain silent and the right to counsel apply from the moment of detention. A suspect who does not speak Turkish has a statutory right to an interpreter, and the quality of that translation becomes part of the defense record, not a side detail. Serka attends the statement stage, reviews what has already been recorded, and intervenes before procedural mistakes harden into evidence.
- Ask for the accusation, the authority handling it, and the case number in writing.
- Do not waive the right to a lawyer to “speed things up.”
- Have the embassy or consulate notified; consular notification is a recognized right.
- Preserve passport, residence permit, and travel records for the immigration side of the file.
How does criminal procedure work for foreigners in Turkey?
Criminal procedure in Turkey moves through four stages: police custody, prosecution investigation, trial before the competent criminal court, and appeal. The Code of Criminal Procedure No. 5271 sets the rules for detention, statements, evidence, and review, while the offense itself is defined by the Turkish Penal Code No. 5237 or a related special statute.
- Custody and statement. Police take an initial statement; counsel and an interpreter must be available.
- Prosecution. The public prosecutor investigates, may seek arrest before a criminal judgeship of the peace, and decides whether to file an indictment.
- Trial. The competent criminal court hears evidence; the defendant has the right to attend, to challenge evidence, and to be heard through an interpreter.
- Appeal. A conviction can be carried to the regional court of appeal and, on points of law, to the Court of Cassation.
Can I be detained before trial, and how is release obtained?
Yes. A foreign national can be placed in pre-trial detention (tutukluluk) if a criminal judgeship of the peace finds strong suspicion and a ground such as flight risk or evidence tampering. Detention is not automatic. The defense applies for release or for judicial control measures (adli kontrol) such as a travel ban, reporting obligations, or security, and objects to a detention order before the reviewing court.
For foreigners, flight risk is the prosecution’s usual argument, so the release strategy focuses on Turkish address, employment, family ties, and a credible plan to remain available. Serka files the objection within the statutory period and requests judicial control as a proportionate alternative to detention.
What types of criminal cases does the firm handle for foreign clients?
Serka Law Firm defends foreign nationals across the categories that most often reach international clients in Turkey: economic and financial offenses, customs and import-export matters, immigration-related offenses, traffic and assault cases, narcotics charges, and cases arising from international cooperation requests. Each is handled with the residence and entry-ban consequence assessed from day one.
- Economic and financial crime: fraud, breach of trust, forgery, and money-laundering allegations.
- Customs, smuggling, and import-export offenses affecting traders and investors.
- Narcotics and possession charges, including airport and border cases.
- Assault, threat, and traffic offenses involving foreign residents and visitors.
- Cybercrime and digital-evidence cases, including data and crypto-related allegations.
- Offenses connected to residence, work-permit, or visa status.
What is Interpol Red Notice and extradition defense?
A Red Notice is an Interpol request to locate and provisionally arrest a person pending extradition; it is not a verdict and it is not a Turkish arrest warrant. A foreign national can challenge a Red Notice before the Commission for the Control of Interpol’s Files (CCF) on grounds such as political motivation or due-process violations, and can contest extradition before the Turkish courts that examine the request.
Extradition from Turkey is decided through a judicial process and is refused in defined situations, including where the request is politically motivated or where fundamental-rights guarantees are not met. Serka builds the CCF challenge and the domestic extradition defense as parallel tracks and coordinates with counsel in the requesting state where needed.
How does a criminal case affect my residence permit or trigger deportation?
A criminal investigation or conviction in Turkey can lead to a deportation decision and an entry ban under Law No. 6458 on Foreigners and International Protection, separately from any criminal sentence. The deportation file is administrative, runs on its own deadlines, and must be answered even while the criminal case continues.
This is where a single coordinated strategy matters most. A defense lawyer who handles only the criminal charge may win or settle the criminal case while the client loses residence and faces a years-long entry ban. Serka tracks both files together, files the administrative challenge to a deportation order on time, and aligns the criminal-defense position with the immigration record. For the administrative side, see our work on deportation orders and entry bans and on residence permits and immigration status.
What defense rights do foreign suspects have?
A foreign suspect in Turkey has the right to remain silent, the right to a defense lawyer, the right to a free and competent interpreter, the right to be informed of the accusation, and the right to consular notification. These rights are protected under the Code of Criminal Procedure No. 5271 and the Constitution of the Republic of Turkey, and reinforced by the European Convention on Human Rights, to which Turkey is a party.
A statement taken in breach of these rights, especially without proper interpretation, can be challenged. Preserving and documenting any rights violation early is part of the defense, because it supports later objections and, if domestic remedies are exhausted, an individual application to the Constitutional Court and a later application to the European Court of Human Rights.
Can the case be appealed?
Yes. A criminal conviction in Turkey can be appealed to the regional court of appeal on the facts and the law, and then, on points of law, to the Court of Cassation. After domestic remedies are exhausted, a foreign national may bring an individual application to the Constitutional Court for breach of fundamental rights, and afterward an application to the European Court of Human Rights.
Appeal deadlines are short and start running from notification. Missing an appeal or objection period is one of the most damaging mistakes in a foreign-national file, so the defense calendars every period from the moment a decision is served.
Can a foreign client be represented remotely?
Often, yes. A foreign client outside Turkey can instruct Serka and be represented through a power of attorney, with the lawyer attending hearings and filings on the client’s behalf. Some stages, such as a personal statement or specific hearings, may still require attendance, but much of the criminal and immigration file can be managed without the client being continuously present.
Remote representation requires a properly executed and, where needed, apostilled power of attorney, certified translations of key documents, and a clear communication channel. Serka sets this up at the start so filings are never delayed by missing authority.
What documents and information should I send first?
Send the accusation or charge, the authority and case number, the custody or detention status, any statement already given, and any deadline you have been told. Add passport, residence permit, and a short timeline of events. This is enough to assess whether the urgent step is release, an objection, evidence work, trial defense, appeal, or deportation-risk management.
| Document or detail | Why it controls the file |
|---|---|
| Charge, authority, case number | Identifies the offense, stage, and reviewing court |
| Custody or detention decision | Sets objection and release deadlines |
| Statement record and translation notes | Shows what was said and whether interpretation was adequate |
| Passport and residence permit | Drives the deportation and entry-ban assessment |
| Any served decision or notice | Starts appeal and administrative-challenge clocks |
How much does criminal defense cost?
Criminal-defense fees in Turkey depend on the offense, the stage, the detention status, and whether a parallel deportation file is open. Serka quotes a written, all-inclusive fee after a first review of the documents rather than an open-ended hourly arrangement, so the client knows the cost of the defense before engaging. Urgent custody intervention is scoped separately from full trial representation.
The first review establishes scope and the fastest legally usable next step. The engagement, and the attorney-client relationship, begins only on a signed fee agreement.
How Serka Law Firm runs a foreign-national criminal file
Serka works in four moves. We stabilize the custody stage and stop avoidable statements; we map the offense, stage, deadlines, and deportation exposure together; we act by filing objections, release or judicial-control requests, evidence challenges, and the administrative immigration response on their own clocks; and we carry the matter through trial, appeal, and, where fundamental rights were breached, Constitutional Court and European Court of Human Rights remedies.
Frequently asked questions
Will I be deported if I am convicted?
A conviction can lead to a deportation decision and entry ban under Law No. 6458, but deportation is a separate administrative process with its own challenge. The outcome depends on the offense, the sentence, and the immigration defense filed alongside the criminal case.
I do not speak Turkish. Can I be questioned without an interpreter?
No. You have a right to a free, competent interpreter when a statement is taken. A statement recorded without adequate interpretation can be challenged, so the translation record is part of the defense, not a formality.
Can I leave Turkey while my case is pending?
Not freely. The court may impose a travel ban as a judicial-control measure, and leaving without permission can be treated as flight and damage the case. Travel must be addressed through the court, not assumed.
I received a Red Notice. Am I already convicted?
No. A Red Notice is a location-and-arrest request, not a judgment. It can be challenged before Interpol’s Commission for the Control of Files, and any extradition is decided separately by the courts.
How fast must I act after a decision is served?
Immediately. Objection and appeal periods in criminal procedure are short and start from the date of service. Send the served decision the day you receive it so the deadline is not lost.
