Private investigations in Milan.
Confidential investigations for individuals, families and professionals who need definitive answers and legally admissible evidence.
When you need for certainty.

Relying on a legally authorized private investigation agency is the only lawful tool to turn personal doubts and suspicions into documented certainties with evidentiary value. In private disputes, self‑initiated actions or do‑it‑yourself methods are not only ineffective in court, but expose the individual to serious criminal liability, such as the offense of unlawful interference with private life (art. 615-bis c.p.) or stalking. Intervention by qualified professionals guarantees the legality of information gathering to protect a subjective right.
Arcadia Company operates under a Prefectural License pursuant to art. 134 T.U.L.P.S., developing private investigations aimed at producing irrefutable evidence before civil and criminal courts. Our organization serves as a strategic interlocutor for individuals and law firms, providing concrete solutions in situations of high emotional and financial complexity, ensuring utmost confidentiality and the adoption of cutting‑edge operational protocols.
Family law and forensic validity of evidence
In judicial separation proceedings, the request for fault‑based attribution under art. 151 of the Civil Code or the recalculation of economic provisions demands absolute evidentiary rigor. Mere suppositions or partial reconstructions have no relevance to the judging body. Investigative dossiers prepared by Arcadia Company are specifically structured to meet procedural admissibility criteria, withstanding counterpart objections.
Systematic collaboration with renowned law firms specialized in family law ensures that every investigation (from verification of moral conduct to mapping the true economic‑patrimonial capacities of the spouses) becomes a decisive evidentiary pillar for protecting our clients' rights and safeguarding family assets.
Forensic operation and testimony in court: At the conclusion of each investigation, Arcadia Company issues a detailed final technical report, supplemented with geolocated photo‑video records. Private investigators employed by the agency, having personally carried out observation and tailing activities, are authorized to testify before the judicial authority to confirm the authenticity of the recorded facts, safeguarding the effectiveness of the evidence.
Technological rigor and GDPR compliance
Each investigation is planned by performing a preventive balance between the client’s informational need and the right to privacy of the monitored subjects, in full compliance with the European GDPR Regulation and the Private Investigators’ Code of Ethics. Evidence collected through our protocols is considered “lawful” because it is closely linked to the exercise of the right of defence in court, eliminating the risk of inadmissibility in proceedings.
Our operational centre coordinates rapid interventions across the national territory, using state‑of‑the‑art locating equipment and optical documentation to ensure clear and immutable records even in complex environmental contexts. For an in‑depth look at data‑processing limits in investigations, you can consult the official website of the Garante per la protezione dei dati personali.
How much does a private investigation cost?
The cost of a private investigation varies according to the type of inquiry, the number of operators involved, the duration, and the area of operation.

Arcadia Company applies a policy of total transparency: every quote is free, detailed, and binding. For an immediate estimate, the online fee calculator is available.

The duration depends on the complexity of the evidentiary objective.

Questions frequent.
Answers to the most common questions about private investigations: evidence admissibility, legality, timelines, costs and confidentiality.
When can I turn to a private investigator?
You may engage an authorized investigative agency whenever you need to protect a personal right: suspected marital infidelity, child custody matters, maintenance allowance revision, stalking, missing‑person searches or criminal defensive investigations. The investigator gathers documentary evidence usable in court in compliance with GDPR.
Are the evidence collected by a private investigator admissible in court?
Yes. Arcadia Company operates under a Prefectural License pursuant to art. 134 T.U.L.P.S. and produces technical reports accompanied by geolocated video‑photo records. The Court of Cassation has repeatedly confirmed the full admissibility of evidence gathered by authorized agencies; our investigators are available to testify in court.
Is it legal to have your spouse or partner followed?
It is lawful to commission an authorized agency to ascertain behaviours relevant to the protection of a right, such as the attribution of separation. It is not permitted to do‑it‑yourself: installing GPS or accessing third‑party devices can constitute offences such as illegal interference with private life (art. 615-bis c.p.). For this reason it is essential to rely on authorized professionals.
How long does a private investigation last?

Is my privacy as a client guaranteed?
Absolutely. The initial interview is protected by professional secrecy. We adopt GDPR‑compliant protocols: encrypted communications, secure storage and access limited to the operational team only. The client’s identity is never disclosed.
