What Qualifies Our Swiss Detectives? | Professional, Lawful, Experienced

The first principle of any reputable Swiss detective is a solid understanding of the federal legal framework. Prohibited investigative methods such as covert audio recordings and video surveillance in private spaces, which infringe upon the target’s personal sphere, are strictly forbidden. If our investigators were to use illicit means, not only would our detective agency in Zurich face criminal consequences, but any evidence obtained in this manner would also be inadmissible in court.

Our Swiss operatives are trained investigators, qualified IT specialists, and professional security experts with many years of experience in their respective fields. Regular training in both investigative methods and legal matters ensures that our detectives maintain their top-level expertise. Thus, our clients can be certain of always receiving the best possible advice and support.

Kurtz Detective Agency Switzerland: Expertise Combined with Technology

Beyond knowledge of the law and investigative techniques, our Swiss detective agency also operates with outstanding technical equipment. This includes high-quality camera systems and a range of vehicles, as well as forensic tools (for instance, for securing traces) and devices for detecting listening equipment. In addition, we cooperate with excellent dog handlers who train their tracking dogs daily in mantrailing.

Our detectives in Switzerland take on only those cases where both a legitimate interest exists and our operatives are not personally involved (keyword: impartiality). Professional and independent investigations, precise documentation of observed or researched facts, legally compliant photographic evidence, and, where necessary, testimony in court ensure the admissibility of evidence. Furthermore, our private investigation agency stands for a fair price-performance ratio: you may set a contractual budget limit, and our principle is that no more investigators or resources are deployed than necessary—without, however, jeopardising the success of the operation through excessive savings.

What Are Investigators Not Allowed to Do?

Detectives who investigate individuals without a legitimate interest are committing an offence, as they are unlawfully infringing upon the person’s right to privacy. An exception applies if the investigators were deceived by the client and therefore believed a legitimate interest existed. In such a case, the client who acted fraudulently will have to answer to the court.

Moreover, any evidence obtained without legitimate interest will generally be inadmissible in legal proceedings. Image and audio recordings are also subject to personal rights. Audio recordings, in particular, are strictly prohibited under Art. 179ter of the Swiss Criminal Code, which protects the right to one’s own words. Similarly, Art. 179quater governs image recordings, though its interpretation is somewhat less restrictive. However, the highly personal intimate sphere is strictly protected—photographing or filming the subject in non-public indoor areas (such as bathrooms or bedrooms) is prohibited. Conversely, photographic evidence of investigatively relevant activities in public spaces is generally considered proportionate and therefore lawful.

In every case, the prerequisite for taking photographs is the legitimate interest of the person taking them—or of a third party on whose behalf they are taken (the client). The images may not be published in the media without the subject’s consent and may only be used for evidentiary purposes. Our trained private investigators in Switzerland strictly adhere to all legal requirements. We are happy to explain our methods in detail and answer any related questions by phone: +41 44 5522 264.
