How to Obtain a Copy of Your Criminal Investigation File in Turkey | 2026 Updated Legal Guide

Learn how to obtain a copy of your criminal investigation file in Turkey. Discover who may access investigation documents, confidentiality rules, defense rights, foreign nationals’ rights, and legal procedures in this 2026 Updated Legal Guide.

Being involved in a criminal investigation in Turkey can be stressful, particularly for foreign tourists, expatriates, international students, investors, and business professionals who are unfamiliar with the Turkish legal system. One of the first questions asked by suspects, victims, and complainants is whether they can obtain a copy of the criminal investigation file and review the evidence collected by the authorities.

Access to investigation files is governed by the Turkish Criminal Procedure Code. While parties may have important rights to examine certain documents, access is not always unlimited. During the investigation stage, prosecutors may impose confidentiality restrictions to protect evidence, prevent interference with the investigation, or safeguard the rights of victims and witnesses.

This 2026 Updated Legal Guide explains who may obtain a copy of a criminal investigation file in Turkey, how the procedure works, and the legal rights of foreign nationals during criminal investigations.

What Is a Criminal Investigation File?

A criminal investigation file is the official collection of documents prepared during the investigation conducted by the Public Prosecutor.

The file may contain:

• Criminal complaints.
• Police reports.
• Witness statements.
• Suspect statements.
• Victim statements.
• Expert reports.
• Digital evidence.
• CCTV recordings.
• Search records.
• Seizure reports.
• Forensic reports.
• Official correspondence.
• Prosecutorial decisions.

The contents vary depending on the nature of the investigation.

Who May Request Access?

Depending on the procedural stage and applicable legal rules, access may be available to:

• Suspects.
• Defense lawyers.
• Victims.
• Complainants.
• Victims’ legal representatives.
• Lawyers acting under a valid power of attorney.

The scope of access differs according to the person’s procedural status.

Can Foreign Nationals Obtain the File?

Yes.

Foreign nationals generally have the same procedural rights as Turkish citizens during criminal investigations.

This includes:

• Foreign tourists.
• Residence permit holders.
• International students.
• Investors.
• Business owners.
• Employees.
• Company representatives.

Nationality does not prevent access where Turkish law permits file examination.

Is the Investigation File Always Open?

No.

Many criminal investigations remain confidential during the early stages.

Confidentiality serves several purposes, including:

• Protecting evidence.
• Preventing witness interference.
• Avoiding destruction of evidence.
• Protecting victims.
• Ensuring the effectiveness of the investigation.

The existence of confidentiality does not eliminate procedural rights but may temporarily limit access to certain materials.

What Is a Confidentiality Order?

A prosecutor or competent criminal court may impose a confidentiality order during an investigation where legally justified.

Such an order may restrict access to:

• Witness statements.
• Expert reports.
• Digital evidence.
• Surveillance records.
• Technical reports.
• Certain investigative documents.

The extent of the restriction depends on the specific judicial decision.

Can a Lawyer Review the Investigation File?

Yes.

Defense lawyers generally have broader procedural rights than suspects acting without legal representation.

A lawyer may:

• Examine accessible investigation documents.
• Request copies of available records.
• Review procedural decisions.
• Identify missing evidence.
• Prepare the legal defense.
• Submit legal objections.

Professional legal representation often provides significantly greater procedural protection.

How Can You Obtain a Copy of the File?

Depending on the circumstances, access may involve:

• Applying through a lawyer.
• Requesting examination of the investigation file.
• Seeking copies of accessible documents.
• Reviewing documents at the relevant prosecutor’s office.
• Receiving officially authorized copies where legally permitted.

The exact procedure depends on the stage of the investigation.

Can You Obtain Digital Evidence?

Possibly.

Where legally permitted, accessible evidence may include:

• Written statements.
• Expert reports.
• Financial records.
• Medical reports.
• Certain photographs.
• Investigation records.

However, confidential digital evidence may remain inaccessible until procedural restrictions are lifted.

What If Access Is Refused?

Access may be restricted because of:

• Confidentiality orders.
• Ongoing investigative activities.
• Protection of witnesses.
• National security concerns where applicable.
• Judicial decisions.

A lawyer may evaluate whether the restriction complies with Turkish criminal procedure and whether legal remedies are available.

Can Victims Access the Investigation File?

Victims and complainants may have procedural rights to review certain parts of the investigation.

The available access depends upon:

• Their procedural status.
• The stage of the investigation.
• Confidentiality decisions.
• Judicial orders.

Each request is assessed individually.

Can You Obtain the File While Living Abroad?

Yes.

Foreign nationals who have already left Turkey may still protect their procedural rights.

A lawyer acting under a properly executed power of attorney may:

• Examine accessible investigation documents.
• Obtain authorized copies where permitted.
• Monitor procedural developments.
• Communicate with prosecutors.
• Submit legal applications.
• Represent the client throughout the investigation.

Personal presence in Turkey is often unnecessary once legal representation has been established.

Can Investigation Files Be Used in Civil Cases?

In some situations, yes.

Evidence obtained during criminal investigations may also become relevant in:

• Compensation claims.
• Commercial disputes.
• Employment litigation.
• Insurance claims.
• Administrative proceedings.

The admissibility of evidence depends on the applicable legal rules governing each proceeding.

Why Is Reviewing the File Important?

Careful examination of the investigation file may reveal:

• Missing evidence.
• Procedural errors.
• Inconsistent witness statements.
• Unlawful searches.
• Deficiencies in expert reports.
• Problems with digital evidence.
• Opportunities for additional defense evidence.

Early review often strengthens legal strategy.

Rights of Foreign Nationals During Investigations

Foreign nationals generally have the right to:

• Legal representation.
• Assistance from an interpreter.
• A fair trial.
• Review accessible investigation materials through lawful procedures.
• Submit evidence.
• Challenge unlawful investigative measures.
• Appeal judicial decisions where permitted.

These procedural safeguards apply regardless of nationality.

Common Mistakes Made During Criminal Investigations

Individuals frequently:

• Delay hiring a lawyer.
• Assume they cannot access the file.
• Ignore confidentiality rules.
• Sign documents without legal advice.
• Miss procedural deadlines.
• Fail to preserve favorable evidence.
• Delay requesting access to available documents.
• Communicate with investigators without legal guidance.

Early legal assistance helps avoid these mistakes.

Why Professional Legal Assistance Is Essential

Accessing and reviewing a criminal investigation file requires knowledge of criminal procedure, confidentiality rules, evidentiary principles, and defense strategy.

An experienced criminal defense lawyer can:

• Examine accessible investigation documents.
• Request authorized copies.
• Challenge unlawful confidentiality restrictions where appropriate.
• Analyze digital and forensic evidence.
• Identify procedural violations.
• Prepare legal objections.
• Protect procedural rights.
• Develop an effective defense strategy.

Professional legal representation is often the most effective way to protect your interests throughout the investigation.
