Adultery and Infidelity: the essential role of the private investigator

In the complex world of human relationships, delicate situations, such as adultery, can arise. When you are faced with suspicions of infidelity on the part of your partner, it becomes essential to have concrete evidence to determine the truth.

In this situation, you can turn to an experienced professional: the private investigator specialized in adultery.

Capable of conducting discreet and thorough investigations, this private detective in the field of private investigation provides clear answers and undeniable evidence to help you make an informed decision.

Let’s now look in more detail at how this investigator can provide you with solid and indispensable evidence while respecting the confidential and delicate nature of the situation.

Adultery and Infidelity: the essential role of the private investigator

In the event that you suspect your partner of adultery or infidelity, turning to a private investigator can be an effective solution to obtain concrete evidence. Indeed, private detectives are professionals specialized in the search for information and the collection of evidence to detect dubious behavior.

In the case of suspicion of adultery or infidelity, they mainly take care of:

  • Monitoring your spouse or partner himself/herself.
  • Tailgating, which involves discreetly following him/her.
  • Researching and analyzing elements or information that can prove infidelity: photos, videos, testimonials are among the most important tasks that a private investigator specialized in adultery is responsible for carrying out.

Why hire a private investigator in situations of adultery and infidelity in Switzerland?

Here are the main reasons why you might consider hiring a professional in private investigation to help you deal with this difficult situation.

For personal reasons

Your personal reasons for hiring a private investigator can go well beyond the mere legal framework. After all, the quest for truth is a fundamental human aspiration.

In the context of your romantic relationship, knowing the truth can be vital for your decision-making and emotional well-being. You may feel the need to confirm or deny your suspicions in order to move forward.

This is where a private investigator can step in. With their professionalism and discretion, they can provide you with the necessary information to face reality, make informed decisions, and ultimately regain some peace of mind.

For legal reasons

Swiss law provides another reason why you might need a private detective in cases of suspected adultery: obtaining protective measures for the marital union if you are married.

Even though the Swiss divorce law, which came into effect in 2000, abolished the notion of marital fault, proof of adultery can help you obtain these protective measures. They may be necessary if family obligations are not met or in case of a major disagreement. They are there to protect your marriage or one of its members.

The evidence gathered by a private detective can therefore help you organize the separation and implement these measures, especially regarding financial contributions, housing allocation, or child custody.

However, it is crucial to understand that evidence collected from adultery can never be used as valid and serious grounds within the framework of a divorce, in the eyes of Swiss courts.

Adultery and Infidelity: Investigation Methods to Prove Adultery

Here are some investigation techniques commonly used by the marital detective to gather evidence of infidelity:

  • Tailgating: This method involves discreetly monitoring and following the person suspected of infidelity in order to observe their movements and activities.
  • Locating Meeting Places: It is often useful to know the meeting places frequented by the unfaithful person. Private investigators can identify these locations through surveillance and analysis of schedules.
  • Searching for Irrefutable Evidence: Obtaining photographs, testimonials, or incriminating messages is crucial to prove adultery.
  • Examining Social Networks and Dating Sites.
  • Investigating Cohabitation: If the suspicion of infidelity concerns a long-term relationship, private detectives can check if the suspected person officially lives with their lover or mistress.

In this approach, the role of the private investigator is essential. Indeed, the detailed report they produce constitutes a solid basis to confirm adultery.

However, before deciding to hire a private detective for adultery, it is important to be aware of the consequences that such a step can lead to. In some cases, reconciliation may be preferable to searching for evidence of infidelity.
