Who we work with
Hiring a private investigator in Athens, Greece
A private investigator in Athens is far more than someone who follows people. It is a licensed professional who knows exactly where the law ends and where the risk to the client begins. The office of Petros Drolias is at 104 Aiolou Street, a few minutes from Omonia metro station, and covers the whole of Attica, Piraeus and the rest of Greece.
Foreign individuals, law firms, insurers and shipping companies work with us when they need reliable answers on the ground in Greece: locating people and assets, background and due-diligence checks, evidence for court proceedings, counter-surveillance sweeps and fraud investigations. The first conversation is free and confidential, and every assignment starts with a written plan and cost estimate.

How much does a private investigator cost?
There is no standard price, because cases differ in duration, location and resources. After the first consultation you receive a tailored cost estimate in writing, before any work begins, so there are no surprises.
Do you work in English?
Yes. We hold consultations, correspond and write reports in English, and we regularly work with clients who do not speak Greek.
I live abroad. Can I hire you without travelling to Greece?
Yes. The consultation can take place by phone or video call, the plan and cost estimate are agreed in writing, and updates and the final report are sent to you securely.
