Nikos Pelekasis & Associates is a Private Investigation Agency in Greece with more than 30 years of experience in private, corporate and specialised investigations. Based in Athens and operating throughout Greece, our agency provides discreet and professional investigative services to private individuals, businesses, law firms and international clients.
Since the beginning of our activity, our approach has been based on three fundamental principles: confidentiality, professionalism and reliable investigative information.
Private investigation has changed considerably over the past three decades. Traditional field investigation and surveillance remain important, but modern cases increasingly involve smartphones, computers, social media, digital evidence and sophisticated electronic technology.
For this reason, our investigative approach combines experience in traditional private investigation with modern digital and technical investigative capabilities.
Experience in private investigation is not simply a matter of how long an agency has existed.
Every investigation presents different circumstances, personalities, risks and limitations. Over more than three decades, Nikos Pelekasis & Associates has handled a wide range of private, family, corporate and professional cases.
This experience allows us to evaluate each new assignment individually and determine which investigative methods are appropriate for the circumstances.
We do not approach every investigation with the same methodology.
Depending on the case, an investigation may require:
The objective determines the methodology — not the other way around.
Our agency is based in Athens and undertakes investigations throughout Attica and Greece, depending on the requirements of each assignment.
Our operational coverage can include:
We also regularly communicate with international clients, companies and law firms requiring investigative assistance in Greece.
Initial case assessment can be conducted remotely, allowing international clients to discuss the circumstances and objectives of an investigation before travelling to Greece or commissioning local investigative work.
Our agency provides a broad range of private detective services in Greece for individuals, families and professionals.
Personal and family investigations can include matters involving:
Every case is approached discreetly and according to its individual circumstances.
Our purpose is not to confirm assumptions or suspicions at any cost. It is to establish what can actually be supported by the information and evidence available.
Businesses and professional organisations often face investigative challenges that require a different approach from ordinary private cases.
Our corporate investigation services can assist businesses, lawyers and other professionals with matters involving:
Corporate assignments frequently involve sensitive commercial information and require particular attention to confidentiality.
Where lawyers, accountants, technical experts or other professionals are involved, our investigative work can be coordinated with them according to the requirements of the case.
Modern investigations increasingly involve electronic evidence.
Smartphones, computers and digital storage devices can contain information relevant to private, corporate and legal matters.
Our Digital Forensics capabilities can assist in the examination of lawfully accessible digital devices and information.
Depending on the circumstances, an investigation may involve:
Digital forensic examination is not the same as unauthorised access to another person’s device or account.
Before an examination is undertaken, the lawful authority and legitimate purpose of the investigation must be established.
Concerns regarding unauthorised monitoring of smartphones have become increasingly common.
Where there are legitimate technical indications that a device may have been compromised, our Mobile Spyware Detection services can examine relevant indicators on authorised devices.
Depending on the case, examination may involve suspicious applications, configurations, network behaviour and other technical information.
We do not assume that unusual smartphone behaviour automatically indicates spyware.
Technical conclusions should be based on evidence identified during examination.
Electronic surveillance concerns may involve homes, offices, meeting rooms or vehicles.
Our Technical Surveillance Counter-Measures (TSCM) services are designed to examine environments for indications of unauthorised electronic surveillance.
Depending on the circumstances, inspections may involve specialised equipment and multiple technical methods.
TSCM services can be relevant to:
No single detector or technique can identify every possible surveillance device, which is why professional TSCM requires a systematic approach.
A significant part of modern investigative activity now takes place online.
Social media can provide valuable information, but it can also be used for:
Our Social Media Investigations combine publicly accessible information, OSINT and other lawful investigative methods to examine legitimate concerns involving online activity.
Information discovered online must be carefully evaluated and cross-referenced.
A photograph, username or profile similarity alone should not automatically be treated as proof of identity.
One of the most important principles of professional investigation is maintaining a distinction between suspicion and evidence.
A client may have strong reasons for believing that something has occurred.
However, the role of an investigator is not simply to confirm that belief.
Our objective is to establish:
This approach is particularly important where the findings may influence important personal, commercial or legal decisions.
Depending on the nature of the assignment, findings may be documented in a professional investigative report.
A report can include:
Reports should clearly distinguish between verified facts, investigative observations and information that cannot be independently confirmed.
Where an investigation relates to legal proceedings, coordination with the client’s lawyer may help ensure that the investigation remains focused on information relevant to the case.
Clients frequently contact a private investigation agency during extremely sensitive personal or professional situations.
They may be dealing with a family issue, suspected infidelity, corporate fraud, theft, harassment, litigation or concerns regarding electronic surveillance.
For this reason, confidentiality is fundamental to our work.
Information concerning:
is handled with discretion and according to applicable legal requirements.
Private investigators do not have the same powers as police, prosecutors or judicial authorities.
A legitimate investigation therefore requires an understanding of what information can lawfully be obtained and which methods are appropriate.
Our investigations do not include unauthorised:
Where information requires judicial or official authority, the appropriate legal process must be followed.
This distinction is particularly important in modern investigations because technical capability does not automatically create legal authority.
Our investigative activities also take into account applicable European data protection requirements when personal data is processed.
We can provide investigative assistance to law firms and legal professionals requiring factual research, evidence collection or specialised investigative support in Greece.
Depending on the matter, assistance may include:
When litigation is involved, cooperation with the lawyer can help define the investigative objective and determine which information may be relevant to the proceedings.
International clients may encounter difficulties when attempting to conduct an investigation in another country.
Language, geography, local procedures and access to reliable local information can make even relatively straightforward enquiries difficult.
Nikos Pelekasis & Associates assists international:
with legitimate investigative matters connected to Greece.
Communication can be conducted in English, and the scope of an assignment can be established remotely before investigative activity begins.
Private investigation has evolved considerably during the last 30 years.
The investigator of today must understand both traditional investigative methodology and the role of modern technology.
A single case can involve physical surveillance, social media, smartphones, digital files, public records and electronic evidence simultaneously.
Our approach therefore combines established investigative experience with modern capabilities such as:
Digital Forensics • TSCM • OSINT • Mobile Spyware Detection • Social Media Investigation • Data Recovery
Technology is a tool within an investigation — not a substitute for investigative judgement.
Our agency brings more than 30 years of experience in private and professional investigations.
We handle personal investigations as well as complex corporate and digital assignments, allowing different investigative methods to be combined when necessary.
Sensitive information is handled discreetly and according to the defined purpose of the investigation.
Our objective is to establish facts rather than simply confirm suspicions.
Where appropriate, investigations can incorporate Digital Forensics, TSCM, OSINT, data recovery and other modern investigative techniques.
We undertake investigations in Athens, Piraeus, Attica and throughout Greece, depending on the requirements of the case.
We assist foreign individuals, companies, law firms and professional investigation agencies with cases connected to Greece.
Before beginning an assignment, we aim to understand three fundamental points:
What does the client need to establish?
What information is currently available?
Which investigative methods can realistically and lawfully provide additional information?
Once these questions are answered, an investigative strategy can be developed according to the circumstances.
Some cases can be resolved relatively quickly.
Others require a combination of different investigative methods over a longer period.
Clients should receive a realistic assessment of what an investigation can and cannot achieve before unnecessary resources are committed.
