Marital infidelity: legally valid evidence.

Discovering marital infidelity is one of the most destabilising experiences a person can go through. Personal anguish is almost always accompanied by a practical question: how do I protect myself? Whether you are considering a separation, a fault‑based separation lawsuit, or simply the need for clarity, the answer almost always depends on the quality of the evidence collected.

The problem is that many people, driven by emotional urgency, try to gather this evidence on their own. It is a mistake that can have serious consequences, both legally and personally.

Why evidence collected independently rarely works

To obtain a fault‑based separation (art. 151 c.c.) it is necessary to demonstrate a breach of the marital duties established by art. 143 c.c. However, the evidence must be gathered in full compliance with the law. Those who act without professional support often make mistakes that render the evidence inadmissible or, worse, expose them to criminal liability:

• Unauthorized interceptions: recording telephone or ambient conversations without the interlocutor’s consent violates art. 615-bis c.p. and art. 617 c.p. Such recordings are not admissible in court and the party commissioning them risks becoming, in turn, a defendant.
• Recordings in private places: photographing or filming the spouse inside private residences — even via hidden cameras or drones — constitutes a violation of the right to privacy, with criminal risks directly borne by the person who arranged them.
• Unauthorised access to devices: reading messages, e‑mail or accessing the partner’s social‑media accounts without permission fulfills the offence of unauthorised access to an information system (art. 615-ter c.p.), regardless of the level of trust with the person.

In contrast, a report prepared by an authorized private investigator pursuant to art. 134 TULPS constitutes documentary evidence that meets procedural admissibility requirements and can be filed in the civil proceedings.

Arcadia Company’s ISO 9001 certified methodology

Arcadia Company operates in compliance with the ISO 9001:2015 certification, meaning that every assignment — from feasibility analysis to dossier delivery — follows documented, verifiable and up‑to‑date protocols. For the client, this translates into concrete guarantees:

• GDPR‑compliant: all observation, tailing and document‑collection activities are carried out within the limits set by the Garante for personal data protection and EU Regulation 2016/679. The investigation is solely aimed at protecting the client’s subjective right.
• Procedurally valid dossier: the final technical report includes geolocated photographic records, a chronology of activities and the signature of the investigation manager. It is structured to meet the requirements of art. 2697 c.c. on the burden of proof. Our investigators are available to testify in court.
• Absolute confidentiality: from the first contact to the delivery of the documents, data are handled in secure environments with access limited to the operational team only. The relationship between agency and client is covered by the professional confidentiality obligation.

Sesto San Giovanni and North Milan: close to you, without travel surcharges

Arcadia Company’s operational headquarters is located in Sesto San Giovanni, at Piazza Don Mapelli 60 — a position that allows us to effectively cover the entire northern Milan area, the surrounding municipalities (Cinisello Balsamo, Cologno Monzese, Bresso, Cusano Milanino) and the whole province of Monza and Brianza.

Thanks to this proximity, assignments are activated quickly — usually within 24-48 hours of the initial interview — without applying surcharges for local intervention expenses. Each operational plan is presented with its budget before the investigation starts: no surprise costs at settlement.

If you are considering how to proceed, the first step is to request a free, confidential preliminary consultation. The initial interview is protected by professional secrecy and entails no commitment.
