How to Become an Expert Witness in Turkey

Anyone who has ever dealt with legal proceedings has likely encountered an expert witness. In the judicial system, an expert witness (bilirkişi) is an objective specialist called upon to clarify complex technical, scientific, or trade-specific details that lie beyond a judge’s general legal training.

While their technical findings and evaluations provide crucial clarity, their reports are not legally binding; judges review their input alongside other evidence to render a fair verdict. Whether you are a software engineer, a master carpenter, an accountant, or an architect, your professional knowledge can help courts establish the truth.

Here is everything you need to know about qualifying and applying to serve as an official court expert witness in Turkey.

Core Eligibility Requirements

To ensure courts receive credible, high-integrity analysis, judicial commissions uphold strict criteria. To be eligible, applicants must satisfy the following conditions:

• Citizenship: You must be a citizen of the Republic of Turkey.
• Age Requirement: You must be over the age of 25 at the time of application.
• Verified Experience: You must possess at least three full years of documented professional experience in your specific field of expertise.
• Clean Record: You must not have been convicted of crimes against the state, nor offenses involving breach of trust, fraud, bribery, embezzlement, forgery, fraudulent bankruptcy, smuggling, bid-rigging, perjury, or providing false expert testimony (even if pardoned).
• Professional Standing: You must not have been subject to disciplinary dismissal from public office or your professional association, nor can you be under a temporary professional ban.
• Geographic Jurisdiction: You must reside or actively practice your profession within the provincial boundaries covered by the judicial justice commission to which you are applying.
• Single Registration: You cannot be registered on an expert witness roster of another commission simultaneously.

The Application and Selection Process

Becoming an expert witness involves a formal administrative process overseen by regional judicial authorities:

1. Monitor the Official Call for Applications: Judicial Justice Commissions (such as the Istanbul Judicial Justice Commission) announce calls for new expert witnesses annually, typically published every October for the upcoming judicial year.
2. Submit Your Credentials: Gather your documentation—including your diploma, professional licenses, employment records proving at least three years in your specialty, and clean criminal background certificates—and apply through the official portal or designated commission office during the open enrollment window.
3. Commission Review: The commission evaluates your qualifications, professional standing, and document validity to determine if you meet the panel’s criteria.
4. The Swearing-In Ceremony: If accepted, your name will be officially enrolled on the roster. You will be invited to attend a formal swearing-in ceremony before the Chief Public Prosecutor or presiding court committee, pledging to carry out your responsibilities objectively, impartially, and conscientiously.

Once sworn in, your name is entered into the official registry, and courts across your jurisdiction may assign cases to you whenever your niche expertise is needed.
