Private Detective Services in Greece require experience, discretion, confidentiality and a professional approach to every case. At Nikos Pelekasis & Associates, we provide specialised investigative services for individuals, families, businesses and legal professionals in Athens, Piraeus, Attica and throughout Greece.
With more than 30 years of experience in private investigations, our agency handles cases ranging from infidelity and family investigations to corporate fraud, digital forensics, TSCM bug sweeps, evidence collection and complex professional investigations.
Every case is different. Before an investigation begins, we assess the client’s objective, the available information and the investigative methods that may lawfully and realistically be used.
Our goal is simple: to provide clients with reliable information and properly documented findings while maintaining discretion and confidentiality throughout the investigation.
Our Private Detective Services in Greece cover a wide range of personal, family, corporate and digital matters.
Depending on the circ
umstances, our services include:
Each assignment is evaluated individually so that the investigation remains focused on the client’s legitimate objective.
Private individuals contact our agency for many different reasons.
Some need to establish facts concerning a personal or family matter. Others are facing harassment, suspected surveillance, theft, online impersonation or another situation where reliable information is difficult to obtain independently.
Our investigators approach these cases discreetly and without predetermined assumptions.
Suspected infidelity can create uncertainty and make it difficult for someone to distinguish between suspicion and fact.
A professional infidelity investigation can help establish relevant information through lawful investigative methods.
Depending on the circumstances, an investigation may involve observation, documentation and other appropriate investigative techniques.
The objective is not to confirm the client’s suspicions at any cost. It is to establish what can actually be verified.
Family-related cases often involve sensitive circumstances and require particular discretion.
Our family investigation services may assist in matters involving:
Because family cases can affect several individuals, every assignment is assessed carefully before investigative activity begins.
Where there are legitimate concerns regarding the safety or welfare of a child, investigative assistance may sometimes provide relevant factual information.
Child custody investigations can involve documentation of circumstances relevant to an ongoing family or legal matter.
Cases involving minors require particular sensitivity.
Where the investigation relates to court proceedings, cooperation with the client’s lawyer is recommended so that the investigative objective remains relevant to the legal issues involved.
Theft can affect individuals as well as businesses.
A professional theft investigation may assist in establishing the circumstances surrounding an incident, identifying relevant individuals, locating witnesses and collecting supporting information.
Depending on the case, digital evidence, CCTV research, field investigation and other methods may form part of the investigation.
Evidence can be important in personal, commercial and legal disputes.
Our evidence collection services may involve the lawful documentation of relevant facts through:
Where evidence may ultimately be used in legal proceedings, clients should discuss the requirements of their case with their lawyer.
Individuals and businesses may sometimes need to locate a person connected with an outstanding financial obligation.
Professional debtor tracing can assist in identifying current location or contact information through lawful investigative methods.
A private investigator does not have the authority of a court or enforcement officer. Our role is to locate and document relevant information that may assist the client and their legal representatives.
Modern investigations increasingly involve smartphones, computers, online accounts and other digital sources.
For this reason, our agency combines traditional private investigation with specialised digital investigative services.
Digital Forensics involves the identification, examination and documentation of relevant information from electronic devices where the client has lawful authority for the examination.
Depending on the case, relevant devices may include:
Digital forensic examination may become relevant in private, family, corporate or legal investigations.
The purpose is not simply to search a device, but to identify relevant digital information according to the defined investigative objective.
A smartphone can contain highly sensitive information concerning communications, accounts, photographs, documents and everyday activity.
Where there are legitimate technical indications that a mobile device may have been compromised, a professional mobile spyware detection examination can assess the device for suspicious applications, configurations or other relevant indicators.
Unusual phone behaviour does not automatically prove that spyware is installed.
For this reason, conclusions should be based on technical examination rather than suspicion alone.
Deleted information may sometimes remain recoverable from smartphones, computers or digital storage devices.
Our data recovery services may assist with information such as:
Recovery is not always possible.
Modern encryption, SSD technology, TRIM, factory resets and continued use of a device can significantly affect whether deleted information remains technically recoverable.
Social media can provide valuable investigative information but can also be used for fraud, harassment, impersonation and other abusive activity.
Our social media investigations may assist with cases involving:
Our investigations use lawfully accessible information and other permitted investigative methods.
We do not provide unauthorised access to private social media accounts, passwords or communications.
Concerns about electronic surveillance require specialist technical examination rather than assumptions based on ordinary electronic interference or unusual device behaviour.
Technical Surveillance Counter-Measures (TSCM) inspections are designed to examine environments for indications of unauthorised electronic surveillance.
Depending on the assignment, TSCM examinations may be appropriate for:
Technical examination can involve multiple methods because no single detector can identify every type of surveillance device.
TSCM may be relevant to private individuals, executives, businesses, lawyers and organisations handling confidential information.
Businesses face investigative challenges that differ significantly from ordinary personal cases.
Financial loss, confidential information, employees, suppliers, competitors and potential litigation can all form part of the same investigation.
Our corporate investigation services are designed for businesses, organisations, lawyers and other professionals requiring discreet investigative support.
Suspected fraud may involve employees, executives, suppliers, customers or external individuals.
Depending on the circumstances, a corporate fraud investigation may examine:
Our role is to establish relevant facts objectively rather than begin from the assumption that misconduct has occurred.
Businesses may require investigative assistance when there are specific concerns regarding employee theft, fraud, conflicts of interest or serious misconduct.
Investigations must have a legitimate purpose and respect applicable employment, privacy and data-protection requirements.
Depending on the case, field investigation, evidence collection and digital forensic examination may be appropriate.
Before entering a significant commercial relationship, companies may require additional information about an individual or organisation.
Investigative due diligence may assist before:
Our research can complement legal, financial and accounting due diligence by examining relevant investigative information and publicly accessible sources.
Businesses handling sensitive commercial information may face concerns involving unauthorised disclosure or suspected surveillance.
Depending on the circumstances, an investigation may combine:
The objective is to determine what can be established from the available evidence and identify potential vulnerabilities.
Law firms and legal professionals frequently require specialised investigative assistance.
Depending on the case, our agency can assist with:
Where litigation is anticipated, direct coordination with the lawyer can help ensure that investigative resources focus on information relevant to the legal matter.
Road accidents can involve conflicting accounts, unidentified witnesses, unavailable CCTV footage and other factual questions.
A private road accident investigation may assist with:
Where specialist accident reconstruction is required, appropriately qualified technical experts may also need to become involved.
Families and legal representatives may sometimes require independent investigative assistance concerning a homicide, suspicious death or another serious case.
A private investigation cannot replace the official investigation conducted by law-enforcement authorities.
However, depending on the circumstances and legal framework, private investigative work may assist with specific matters such as:
Such cases require particular care to ensure that private activity does not interfere with an official criminal investigation.
DNA analysis can provide important scientific information concerning biological relationships and other legitimate investigative questions.
Our agency can assist with the investigative aspects of DNA-related cases and, where appropriate, coordinate with qualified laboratory professionals.
DNA testing may be relevant to:
DNA contains highly sensitive genetic information, so legal authority, consent, privacy and the intended use of the results must be carefully considered.
Certain clients require more than investigative assistance.
Executives, businesspeople, international visitors, families and other individuals may require close protection or security escort services because of specific security concerns.
Depending on the assignment, services may include:
Each assignment is planned according to the client’s individual circumstances and risk profile.
Modern cases rarely exist entirely online or entirely offline.
For example, a corporate investigation may begin with suspicious employee activity and later require digital forensic examination.
A harassment case may involve physical surveillance, social media research and mobile-device examination.
A suspected information leak may require both a corporate investigation and TSCM inspection.
For this reason, one of the advantages of a multidisciplinary investigative approach is the ability to select different methods according to the evidence available.
The investigation should determine the methods used — not the other way around.
Open-Source Intelligence (OSINT) can form part of many modern investigations.
It involves structured research using information lawfully available from sources such as:
Finding information is only the first step.
Professional investigation requires information to be verified, cross-referenced and placed in context before conclusions are reached.
Physical surveillance remains an important investigative method in appropriate cases.
Depending on the legitimate objective, surveillance may assist in establishing factual information concerning activities, movements or events.
However, surveillance is not appropriate for every case.
Before an assignment begins, its purpose, proportionality and applicable legal restrictions must be considered.
Our investigators select the appropriate methodology according to the individual circumstances.
Depending on the assignment, the findings of an investigation can be presented in a professional written report.
A report may include:
A professional report should clearly distinguish between verified facts, investigative observations and information that cannot be independently confirmed.
Confidentiality is fundamental to private investigation.
Clients may provide information concerning personal relationships, family matters, businesses, employees, legal disputes or other highly sensitive circumstances.
Information concerning the client, investigative objective and findings is therefore handled with discretion and according to applicable legal requirements.
The scope of an investigation should also remain limited to information relevant to the legitimate objective of the assignment.
Private investigators do not have the same powers as police, prosecutors or judicial authorities.
A legitimate investigative objective does not provide unrestricted authority to:
Our investigations are conducted with respect for applicable privacy and European data protection requirements, particularly when personal information is processed during an investigation.
Our Private Investigation Services are conducted within the applicable legal framework.
Where information requires judicial or official authority to obtain, the appropriate legal process must be followed.
Our agency is based in the Athens area but undertakes investigations throughout Greece depending on the requirements of each assignment.
Services can be provided in:
We can also assist international clients, companies and law firms with investigations connected to Greece.
International clients can communicate with our office remotely before an assignment begins.
Nikos Pelekasis & Associates has more than three decades of experience in private, family, corporate and professional investigations.
Experience is particularly important when a case requires several different investigative methods or involves sensitive circumstances.
Our services combine traditional private investigation with modern capabilities including:
This allows us to approach complex cases from multiple investigative perspectives.
We do not apply the same investigative procedure to every case.
The appropriate methodology depends on:
The purpose of an investigation is not simply to confirm what a client already suspects.
Our objective is to establish what the available information and evidence actually support.
Every assignment is handled with particular attention to client confidentiality and discretion.

Potentially. The possibility of recovery depends on the device, storage technology, encryption and what has happened since deletion. Recovery cannot be guaranteed.
Private investigators can lawfully collect and document information that may potentially become relevant to legal proceedings. The admissibility and legal significance of evidence should be evaluated by the client’s lawyer and, ultimately, the competent court.
Contact our office and provide a brief description of the matter, the objective of the investigation and any information already available. We can then assess what investigative approach may be appropriate.
