Family investigations throughout history have been presented as a basic service of every detective office, hence family investigations represent a specific section of action within our duties.

We can define family Investigation as that private investigation hired by one of the members of a family nucleus to investigate another family member. Thus the research par excellence within this field would undoubtedly be research on infidelities. It should be noted that adultery – previously punished – is not a crime at present so the unmasking of an infidelity can no longer be considered a crime.

Infidelity can be conceptualized as the broken by one of the parties to the established agreement of fidelity after the union of the same, without necessarily being married, since de facto couples or even couples who do not yet live together are governed by the same concept.


As professional detectives our mission when we investigate a subject of infidelity, is to try a second collateral relationship or just casualties. Infidelities can occur in any social environment, anywhere, any day and at any time.

They do not distinguish between sex or age and we can say bluntly that it is the order of the day, increasingly widespread by the consumer society we face, sometimes becoming something very frequent in family nuclei. To carry out the investigation of an infidelity  we have professional detectives experts in this matter as well as the most cutting-edge technology that sets us apart from the rest.

All the evidence obtained during the course of an investigation is reflected within a report that details with great accuracy all the details that have occurred.


  • Surveillance and monitoring at the request of a legitimate party.
  • Search and location of people, objects, goods and documents in public records.
  • Infidelities, separations and divorces.
  • Reports of paid activity or marital coexistence for the abolition of compensatory pension.
  • Pension claim.
  • Control of children for dubious behaviors, companies, drug use, alcohol.
  • Child leaks from the family home.
  • Inheritances and location of heirs.
  • Genealogy.
  • Ludopathy.
  • Sects.
  • Alcoholism.
  • Concealment of goods.
  • Anti-surveillance service.
  • Contribution of evidence in Family Courts.
  • Premarital reports.
  • Control of domestic service.
  • Control of restraining orders and other judicial breaches
  • Fraudulent school enrolments.
  • Fictitious marriages or convenience indeed.

Surveillance and monitoring services are a basic service of every private detective used to investigate.

Although it may seem to the naked eye to carry out surveillance and follow-ups as something simple the truth is that they are reversed of great complexity and a great specialization. In addition, great knowledge as well as a great experience are necessary to be able to directly execute a direct observation by the private detective.

There are many setbacks that we can encounter in the course of direct observation during the exercise of monitoring and monitoring.

The main problems we can deal with in an overselling way are:

  • Poor planning of the environment.
  • Inadequate target study.
  • Circumstances typical of the workplace. When near work are official institutions or other bodies such as barracks, commissariats, homes of escorted personalities, heavily guarded institutions, etc.
  • Not being communicated by our clients that the investigating suspects they have put a detective on him.
  • To have previously been caught by the client himself for being investigated for having been following him.
  • To have hired detectives who have done a nefarious surveillance and been discovered.

Through surveillance and monitoring we can know a person’s movements and they can reveal a lot of information about them.

We can have knowledge of places you frequent, friends, family, other people you meet with, hobbies, work, habits, level of expenses, form of travel, schedules, deviant behaviors, etc.

However, for a monitoring device to function properly, it is important to have two factors:

  • Time
  • Permanence

This is because in the vast majority of cases it takes large waits for time.

Our detectives in Madrid have great preparation in surveillance and follow-ups, they are taught to persevere.

Our goal is to clarify the doubts of our customers without there being a glimpse of error, fleeing at all times from interpretations and strictly sticking to reality.

The topic of using GPS by private detectives is a topic of debate that is not very clear and that many customers and users ask us about it.

Arga Detectives Group wants to talk about it and how our private detectives in Madrid make use of it when following up on a private investigation in Spain.

The use of it as a general rule is prohibited by regulation and by withdrawal of jurisprudence over the years.

Its use should be restricted to limited uses in private research provided that all legal formalities that must concern the principle of proportionality are complied with.

As a general rule therefore there is no place for use indiscriminately.

Its use is rather when there is authorization from the owners of a vehicle and it wants to know where your vehicle is going.

For example, it is the case of a taxi driver who rents his vehicle to a driver and wants to know if he is actually working and puts a geolocation system in his own vehicle.

Its use must be completely temporary and strictly necessary with the just the duration of the private investigation.

It is therefore clear to point out three important points about the use of GPS by our detectives in Spain:

  • Its use as a general rule in a systematic and indiscriminate way is not permitted.
  • When making use of it within the cases permitted by law the time should be as little as possible and only for the duration of the private investigation.
  • Its use and application shall be governed by the principles of necessity and proportionality.


Monitoring in rural areas is particularly important for the risky of them.

People in the villages know each other, know the cars out there and control outsiders very suspiciously.

It’s very normal for the neighbors themselves to call the Security Forces and Corps when they see private detectives roam the area.

It will be very common to see the local elders walking with the cane and controlling the whole area in an astonishing way.

We must remain camouflaged in our vehicles at all times without leaving them.

Before carrying out all kinds of monitoring we will have to carry out an action plan correctly. To do this we will have to study carefully the whole area as well as all possible escape routes.

This study will take place in two points.

  • Study in the office through google view maps and similar ones.
  • Street study in the place itself and always before starting private research.

We will have to study all those points that may shelter the private detective when he is conducting surveillance and monitoring.

Whenever we can, we’ll get as far away from the subject as possible.

To have a good display we will use binoculars and other analog zoom devices.

When surveillance is done on foot it’s a good idea to buy a newspaper and sit on a bench and pretend to read to go unnoticed. In case we couldn’t have a newspaper, we could get some advertising pamphlet.

The devices we take to investigate, we’ll put them between the papers so they don’t see each other.

The mobile phone is also an element that allows us to go unnoticed to be able to hide when we speak through it.

When surveillance is prolonged in time, it will be advisable to change the place every 50 or 55 minutes so as not to raise suspicion from the neighbors.

We will take care not to expose our recording equipment continuously by removing it only when strictly necessary.

When we have to make use of it we will have to evaluate whether or not we run the risk of taking it outside and exposing it. We’ll never get them out without thinking about it.

It is important when collecting everything that happened to aim in detail everything that happened well on a recorder well with pen and paper, we should not memorize as a general rule.

Vehicles carried out in this type of private investigation by our detectives in Madrid have tinted moons.

It is advisable to sit in the back to go unnoticed. It is interesting sometimes to use some kind of black sheet to cover us if we needed to. This savannah will slide it through the back of the seats so that it is as discreet as possible.

It is interesting to use the sunshade at the front to give the feeling to the curious that the car has been parked for a long time.

It is important not to have distractions while you are watching so as not to lose any detail of the circumstances.

We should not leave the vehicle as a general rule so as not to attract attention.

In foot surveillance, when they are prolonged in time we must wear two garments in such a way that we exchange them so as not to raise suspicions.

When we find ourselves inside the vehicle we will try to wear dark clothes and avoid bright or white garments.

Now let’s list a number of advanced-level recommendations to consider when conducting surveillance and monitoring.

Detective men will start not shaving us a week before the investigative service with the intention of growing our beards. At any given time in the course of the investigation, we will be able to shave in order to change the look.

To withstand the strong summer heat inside a vehicle, we must take cold drinks inside the vehicle as well as some cloth to dry our sweat.

We’ll have to check the sugar drops when we’ve been inside a vehicle for a long time, so we’ll have to bring some kind of food that contains some sugar.

In the breaks we will take care not to make them next to the area where the research is, we will move away from the area until we avoid any direct eye contact by the researcher towards our person.

Before we begin a private investigation, we’ll fill the gas tank completely.



For many people, the role of the private detective in Spain seems unclear. It is important to correctly publicize this profession through the knowledge of its regulations in order to know its regulations.

It should be remembered that private research services are a service for individuals or companies in legitimate interest.

There are very diverse private research services that our detectives in Madrid can perform in Spain.
