Extradition from Turkey: short answer

Türkiye may extradite a foreign national only through the treaty and Law 6706 process, not merely on a diplomatic allegation or INTERPOL hit.

Extradition from Turkey: When Can a Foreign National Be Surrendered? – legal guide

Scope of review: Dual criminality, sentence thresholds, refusal grounds, provisional arrest, assize-court eligibility review and executive surrender under Law 6706; CCF access, correction or deletion of INTERPOL data is outside scope.

Law checked through: 6 September 2026. Responsible lawyer: Attorney Emirhan Keskin.

Extradition from Turkey

Extradition is not deportation. Deportation is an administrative immigration measure and cannot be used to bypass extradition safeguards when the purpose is surrender for prosecution or punishment. Provisional arrest preserves the extradition process but is not a finding of guilt, and an INTERPOL record is not the formal extradition request. The assize court and executive authorities decide Law 6706 surrender issues; the CCF only reviews INTERPOL-system data and cannot grant extradition refusal or release.

The court can find the request inadmissible, find it admissible subject to statutory conditions or address liberty measures while documents are completed. Even where admissible, surrender requires the remaining Law 6706 procedure and applicable assurances. A refusal does not necessarily grant immigration status; any residence, deportation or protection question continues under separate law. No outcome in this profile corrects or deletes INTERPOL data; CCF relief must be pursued separately.

Deadlines, competent court and venue

Filing deadline

For Extradition from Turkey, There is no single deadline applicable to every extradition file: provisional-arrest time limits may come from the controlling treaty and Law 6706, and the formal request must arrive within that case-specific period. Challenge detention and court decisions immediately through the remedy stated in the ruling; where the CMK objection regime applies, the general period is two weeks after learning the decision. Any constitutional complaint ordinarily has a separate 30-day exhaustion period.

Competent court or authority

Territorial venue

In a Extradition from Turkey matter, Venue is determined by Law 6706, including the person's location and statutory fallback rules; it is not selected by the requesting state.

Mediation or prior application

For Extradition from Turkey, Extradition is not subject to mediation or criminal reconciliation. A private settlement matters only if it changes the foreign warrant or prosecution through a formal competent decision.

Interim protection and urgent action

Request release or a proportionate alternative with a fixed Turkish address, passport deposit where ordered, reporting plan and proof of compliance. Demand certified translations of the full request and adequate time to answer. If return creates a real protection risk, pursue the proper asylum or non-refoulement process without assuming that it automatically decides extradition.

In a Extradition from Turkey matter, the right at risk, imminent danger and precise scope of the requested measure must appear in the same application. Interim protection does not replace the final judgment.

Cross-border documents and remote representation

A foreign or digital document used for Extradition from Turkey is checked separately for issuer, country, date, electronic signature, apostille or legalization and certified translation. Admissibility before a Turkish authority and evidential weight are not the same question.

For a client abroad dealing with Extradition from Turkey, the power of attorney must contain the authority required for that Turkish proceeding. Service address, translation route and secure document-transfer channel are fixed at the start.
