It is overwhelming to be pressured with the deceptions and frauds that are being presented today, this kind of rush can lead to make wrong decisions, and even trust who should not, so when it comes to require a private detective can not dispose their cause on anyone, but only on a real detective.

Hiring a private detective in Spain is being a more frequent action than you imagine, because its role has expanded in recent years to try and explore more areas of care, from personal, business, financial and even technological, is a special discipline to clarify all kinds of questions.

There are a number of aspects to take into account when hiring a private detective that you should be aware of. It is likely that at this point you need the services of a private investigator, either as a company or as an individual, but you do not know how to be sure. You feel confused, logically, this situation is much more common than you think, plus the fear of being scammed.

Therefore, we tell you everything you need to know about how to hire a real detective, giving you a professional vision and supporting you with our extensive experience in the sector.

Every detective must have an official license (TIP), issued by the General Directorate of Police, which contains the identification data of the professional. It indicates that the person is legalized to exercise all the functions provided by the private security law as a private detective. This is the only sure way not to make a mistake when hiring a private detective.

In order for the private detective to perform his work, he must be endorsed and supervised by the Ministry of the Interior and the General Directorate of the Police. This is included in the Private Security Law. As well as there are clear benefits of this hiring, it is necessary to dedicate attention to choose the professional that suits your needs, that way you can guarantee that you are in the right hands.

Through Grupo Arga you get a whole area of services with total security and guarantee so that you can resort to any investigation process with the certainty that you are dealing with trained professionals.

Are there differences between hiring private detectives in Spain from a firm or another?

The truth is that there can be tremendous price differences between hiring a specific detective office or another. The amount does not have to be a fundamental element, but it is common sense to charge a minimum for the viability of the investigation. Thus, for example, the hours of private investigation in Spain are around 70 to 90 Euros the base price. If an office charges you much less, let’s take the example of €40, be suspicious. We strongly advise against hiring cheap detectives in Spain. This is because the decrease in money probably leads to a decrease in different aspects such as:

  • Inexperience of the professionals in charge of investigating.
  • Not having qualified personnel to develop a specific investigation.
  • Lack of necessary technical means, etc.

Given this, we recommend spending a little more and ensuring success in private investigation with true professionals such as Grupo Arga Detectives who give you a fair price according to the market.
