Conjugal Infidelity Investigations: Legal Evidence for Fault-Based Separation

Marriage imposes on both spouses a mutual obligation of fidelity, cohabitation, and collaboration in the interests of the family, as expressly stipulated under Article 143 of the Civil Code. The breach of this duty does not merely affect the couple’s emotional and private sphere but also carries significant legal, financial, and relational consequences. When the bond of trust is broken, the objective verification of the facts becomes an essential prerequisite for safeguarding one’s rights in judicial proceedings.

Operating under a regular Prefectural Licence pursuant to Article 134 of the TULPS, Arcadia Company specialises in gathering evidentiary material relating to marital infidelity. Our investigations are structured to document a partner’s conduct in an irrefutable manner, providing legal counsel with a Forensic Investigative Dossier of absolute probative value, admissible in court to support petitions for judicial separation, the determination of maintenance payments, and the protection of minors.

The Legal Grounds for Fault-Based Separation (Article 151 of the Italian Civil Code)

Marital infidelity constitutes the fundamental basis for requesting the attribution of separation liability under Article 151(2) of the Italian Civil Code. Such attribution formally assigns responsibility for the breakdown of the marriage to the unfaithful spouse, resulting in severe financial penalties: the forfeiture of the right to maintenance allowance and the loss of statutory inheritance rights vis-à-vis the other spouse.

The Supreme Court of Cassation’s case law on legitimacy has established that, for misconduct to be proven, it is necessary to demonstrate a clear causal link between the breach of the duty of fidelity and the breakdown of cohabitation. Infidelity must have been the efficient cause of the intolerability of living together, rather than merely a symptom of an already irreparable fracture. The evidence gathered by Arcadia Company is specifically aimed at dating and contextualising the extramarital conduct, providing a chronological record of the breakdown of the marital covenant.

The Legal Risks of DIY Investigations

When suspicions arise, any attempt to gather evidence of infidelity independently exposes the aggrieved party to serious criminal liability, while simultaneously rendering such evidence inadmissible in civil proceedings. Unauthorised investigative conduct frequently constitutes legally actionable offences:

• Unlawful interference in private life (Article 615-bis of the Italian Criminal Code): The use of covert listening devices, ambient recording equipment, or GPS trackers installed on vehicles exclusively used by a spouse constitutes an offence if carried out within private residential spaces.
• Unauthorised access to a computer system (Article 615-ter of the Italian Criminal Code): Unlocking a partner’s smartphone, reading their email correspondence, or accessing their social media profiles without their explicit consent—even if cohabiting—constitutes a criminally punishable offence.
• Harassment or disturbance of individuals (Article 660 of the Italian Penal Code): Persistent stalking, intrusive surveillance, or obsessive behaviour aimed at intercepting a spouse or alleged lover may constitute criminally relevant harassment and disturbance.

Arcadia Company’s intervention ensures full compliance with the law: investigative activities are legitimised by the right to legal defence and are conducted exclusively in public spaces, safeguarding the inviolability of private premises while guaranteeing the full admissibility of findings in court.

Research Lines and Matrimonial Investigation Services

Arcadia Company’s operational protocols are structured around targeted activities, coordinated with the strategy of the family law solicitor:

Video-Photographic Documentation and Surveillance Reconnaissance

Using state-of-the-art night vision and high-magnification optics, our operatives document a spouse’s conduct in public settings, certifying the presence of stable or casual relationships. Every frame and video is geolocated and timestamped with irrefutable accuracy.

Financial and Asset Investigations for Maintenance Allowance

Emotional infidelity is frequently accompanied by the concealment of financial assets. We conduct in-depth asset investigations to uncover undeclared employment ("off-the-books" work), undisclosed current accounts, corporate holdings, or lifestyle changes inconsistent with reported income in ongoing tax proceedings, providing precise parameters for the calculation or reassessment of maintenance payments.

Parental Fitness Assessment and Child Protection

In cases involving minor children, we monitor the partner’s behaviour during custody or visitation periods. We document any instances of harmful conduct, neglect, or exposure of the child to unsuitable environments or third parties incompatible with their psychological and physical development, providing objective evidence to assist the Court in determining sole or joint custody.

Endofamilial Harm and Compensation under Article 2043 of the Italian Civil Code.

Recent jurisprudential developments by the Supreme Court (Cass. Civ. No. 6598/2019) have recognised the viability of so-called intra-family harm arising from infidelity. Compensation for non-pecuniary damage under Article 2043 of the Civil Code is due where the betrayal has been committed in a manner that specifically undermines the dignity, honour, and well-being of the wronged spouse.

Typical examples include the public flaunting of an extramarital affair within the couple’s social or professional circles, resulting in severe reputational damage, or medically verified somatic and psychological repercussions. Arcadia Company’s dossier meticulously documents the harmful dynamics of infidelity, capturing the scandal and the injustice of the harm suffered by the client.

Confidentiality Assurance and Courtroom Support: All investigative activities are conducted under the strictest professional secrecy. Arcadia Company’s field operatives are qualified to appear as witnesses in civil proceedings, formally attesting to the contents of the investigative report and conferring upon it full evidentiary weight as witness testimony.
