In Türkiye different matters are decided by different authorities, and going to the wrong one costs most where the deadlines are shortest. Below is a map for first orientation.

Situation and authority

• Refusal to grant or renew a residence permit — the provincial directorate of migration management; appeal to the administrative court.
• Deportation decision — the governorate; administrative court, seven days from service. Since November 2024 the court’s decision on such an appeal is final — there is no second attempt.
• Placement in a removal centre — the governorate; the challenge goes to the criminal judgeship of peace, not to the administrative court, and is heard separately from the deportation itself.
• Detention on an international wanted notice — the police, then the prosecutor’s office; the person must be brought before a judge within twenty-four hours at the latest, and the time of transfer runs on top of that period and may not exceed twelve hours.
• Extradition case — the request comes through the Ministry of Justice as the central authority, the assize court hears it, then cassation.
• Suspension of an account operation — on the application of the financial intelligence unit.
• A bank refusing service — the bank’s own decision; this is a civil dispute, not an appeal against an act of authority.

The first twenty-four hours decide the most

Within the first twenty-four hours the judge must explain to the detained person the possibility of extradition with their consent and the legal consequences of that consent. Consent moves the case into the simplified procedure and closes off both the full hearing and cassation. The explanation is often given before the person has seen defence counsel.

Two separate branches of justice

Migration matters, administrative fines and refusals by authorities run through the administrative branch: the administrative court, then the higher instances, and once domestic remedies are exhausted the Constitutional Court and then the European Court of Human Rights. Detention, extradition and money laundering cases run through the criminal branch: the criminal judgeship of peace, the assize court, the Court of Cassation.

Choosing the wrong branch usually means not a refusal on the merits but a loss of time — and time is what these cases have least of.

A practical rule

Information about the status of an application, entry bans and district restrictions is regularly given orally — and turns out to be inaccurate just as regularly. Anything you intend to rely on in court must be obtained by a written request with the submission registered. An official’s oral answer has no evidentiary value.
