Your position

Turkish Criminal Defense: Investigation Stages, Detention Appeals & Court Timeline

Assess where you or your family member stands in a Turkish criminal proceeding. Track police interview rights, detention objection deadlines, trial hearings in the Heavy Penal Court (Ağır Ceza), and appeal windows.

Step-by-step conveyancing and procedure stages

1

Emergency response

If you are in custody, we move first to attend the station, assert your rights, arrange a free interpreter and ensure you are not questioned without protection.

2

Understand the file

We obtain access to the investigation file (where permitted), establish the exact allegation and evidence, and explain your real position in plain English.

3

Protect your liberty

At the judge's hearing we argue for release or judicial control instead of remand, and object to any detention decision we consider disproportionate.

4

Build the defence

We gather exculpatory evidence, witnesses, contracts and certified translations, and prepare a considered statement or defence rather than an improvised one.

5

Engage the prosecutor

Where the facts support it, we press for a decision not to prosecute, framing civil disputes as civil and exposing weak or insufficient evidence.

6

Defend at trial

If an indictment is accepted, we represent you fully through the hearings, challenging evidence and presenting your case before the court.

7

Appeal if needed

We diary every deadline and, where grounds exist, pursue istinaf and temyiz appeals to the Regional Court of Justice and the Court of Cassation.

Critical statutory deadlines and calendar windows

Time limits that appear in this case
24 hoursGeneral limit on police custody for an individual offence, plus the excluded travel time needed to bring you before the nearest judge (CMK art. 91).
4 daysMaximum custody for collective offences (committed by three or more people together), extended in stages by written prosecutor's order (CMK art. 91).
7 daysIndicative deadline for an istinaf appeal to the Regional Court of Justice, running from pronouncement or service — confirm the exact date with your lawyer the moment a verdict is pronounced.
15 daysIndicative deadline for a temyiz appeal to the Court of Cassation, where that route is open at all — it is closed for a range of lower-sentence outcomes, so confirm availability and date immediately.

What to do now

If you are stopped, detained or asked to come in, keep the first hour simple and disciplined. These are the things to say, ask for and gather.
