Introduction

The activity of a private investigator in Italy is regulated by specific legislation that establishes professional requirements, operational areas, and methods of conducting private investigations. Contrary to what is often imagined, the private investigator is not a figure who operates freely, but must obtain a prefectural license and comply with specific legal provisions.

The main regulations for private investigators are represented by Article 134 of the Consolidated Law on Public Security (TULPS) and Ministerial Decree 269/2010, which govern the activities of private investigation agencies.

Understanding what a private investigator can do and what the legal limits are is essential both for professionals in the field and for those who intend to rely on private investigations to protect their rights.

Private investigator regulations: the legislative framework in Italy

The regulations on private investigators are built on a system of authorizations and controls that ensures the legality of investigative activities.

The main sources of law are:

  • Art. 134 of the Consolidated Law on Public Security
  • DM 269/2010
  • Code of Criminal Procedure for Defensive Investigations
  • regulation on personal data protection

This regulatory framework establishes who can conduct private investigations and in which operational areas.

Art. 134 TULPS: the license to conduct private investigations

Article 134 of the TULPS represents the legal foundation of private investigative activity.

The regulation states that it is forbidden to conduct investigative activities without a license from the Prefect. This means that the private investigator must obtain a prefectural authorization before being able to carry out any investigative activity.

The prefectural license is issued only after the verification of specific requirements related to:

  • Moral reliability
  • absence of previous issues incompatible with the function
  • professional competence
  • organizational structure of the investigative institute
  • educational qualifications

Without this authorization, conducting investigative activities constitutes a crime.

DM 269/2010: the regulation of private investigation institutes

Ministerial Decree 269 of 2010 represents the most important regulation for the organization and functioning of investigative institutes.

The DM 269/2010 establishes:

  • the requirements to become a private investigator

  • the methods of conducting investigations

Thanks to this regulation, the activity of the private investigator has been standardized at the national level, ensuring high professional standards.

The decree identifies several areas of authorized investigative activity, we mention the main ones:

Private sphere (so-called private investigations)

Among the most frequent activities are:

  • investigations for marital infidelity
  • checks on child custody
  • investigations into harmful behaviors in the family context
  • parental control
  • tracing missing persons

Defensive field (so-called defensive or criminal investigations)

Defensive investigations are carried out on behalf of a lawyer within the context of a criminal proceeding.

These activities allow for the collection of useful elements for the defense of the client.

How a private investigator works: observation and surveillance

From an operational standpoint, the activity of a private investigator is primarily based on techniques of observation and monitoring of behaviors.

The most commonly used investigative techniques are:

  • surveillance activity (static observation)
  • surveillance (dynamic observation)

Static observation

Static observation involves monitoring a specific location from a fixed position to document relevant behaviors.

This technique allows for recording:

  • entries and exits
  • frequentations
  • hours and habits

Dynamic observation

Dynamic observation involves following the investigated subject during their movements.

The activity can be carried out:

  • on foot
  • with motor vehicles
  • with other means of transport
  • with more coordinated operators

This technique allows for the reconstruction of the movements and behaviors of the investigated subject.

Surveillance by the private investigator

Surveillance is one of the most well-known and widely used investigative techniques by private investigators.

Following a subject without being detected requires operational experience, observation skills, and coordination among multiple operators.

Surveillance can be carried out exclusively in public places or places open to the public and must be aimed at protecting a right.

The evidence gathered by the private investigator

Private investigations have the sole purpose of gathering evidence that can be used in court or for the protection of a legitimate interest.

The private investigator can produce:

  • Investigative reports
  • photographic documentation
  • video shooting
  • testimony in court

The investigative report often represents a determining factor in civil, criminal, and labor disputes.

Why rely on a licensed private investigator

Relying on a licensed private investigator ensures that investigations are conducted in compliance with the law.

A regularly licensed investigator operates with:

  • prefectural license
  • compliance with current regulations
  • legitimate investigative methodologies
  • collection of evidence admissible in court

Unauthorized investigative activity constitutes a crime and can compromise the validity of the evidence collected.
