  • Can I claim back the detective costs?

    In many cases, not only in cases of shoplifting, which is common knowledge, but also in many other situations, such as marital disputes, the costs of hiring a private investigator can be recovered from the perpetrator. A private investigator's bill arriving in the mail has also quickly ended many an extramarital affair.

  • Is the use of a private investigator even legal?

    Of course! However, you must have a legitimate interest in the matter. For example: your partner is unfaithful, your employee is leaking company secrets, etc. Mere curiosity is not a reason to hire a detective.

  • When should I hire a private investigator?

    This applies whenever someone causes you harm, but you cannot prove the harm yourself. For example: You have been paying alimony to your ex-wife for years. However, this obligation only exists as long as your ex-wife is not remarried or living with someone else. Now you have heard that your ex-wife has a partner. It is now up to you to either continue paying alimony or hire a private investigator to gather evidence of cohabitation. The questions to be asked are: What will it cost? What will it achieve? Another example: You own a restaurant and discover that your long-time waiter is embezzling money. If you allow him to continue, he will continue to cause you harm. If you fire him, he will receive a large severance package. If a private investigator proves that the waiter is defrauding you, you can dismiss him, and he will forfeit his severance pay. The questions here are the same: What will it cost me? What will it achieve?

  • How much will it cost me if I hire you?

    Our prices can be found under the "Prices" menu item. In cases where you can recover the detective costs as damages or pre-litigation expenses, hiring a detective will ultimately cost you nothing.

  • How long does it take to complete an order?

    The duration of an assignment depends entirely on the behavior of the person being observed. We have completed marital matters in a single afternoon, but when meetings were infrequent and irregular, it has also taken considerably longer.

  • Is it possible that my partner or my boss is listening to my phone?

    Until recently, I would have said that this was absolutely impossible. However, due to technological advancements, I've revised my opinion: Yes, it is possible that your mobile phone is being tapped. Certain mobile phone models are susceptible to this.

  • Can you also open locks?

    No, we can't do that and we don't. We use a locksmith service for such purposes. However, they will only open doors to apartments to which you have authorization.

  • Will my matter be treated confidentially?

    Detectives are bound by confidentiality. In this respect, a detective is subject to the same regulations as a doctor, lawyer, or priest.
