Hiring a Private Detective
in Belgium

When does it make sense, what does it cost and what should you check? Everything you need to know before hiring a private detective.

What does hiring a private detective actually mean?

Hiring a private detective means instructing an independent, licensed investigator to establish facts. Not suspicions, not second-hand accounts, but objective observations with date, time, location and identification.

That is the difference with investigating on your own: what you gather yourself is often legally worthless or, worse, unlawfully obtained. You remain the client throughout. You decide what is investigated, you receive a written agreement in advance, and afterwards you get a report you are free to use. Everything the detective learns about you and your case falls under statutory professional privilege.

  • Objective findings instead of suspicions
  • Admissible before Belgian, Dutch and French courts
  • Statutory professional privilege on your case
  • You set the brief, we report the facts

In short

Start free and without obligation

The first conversation costs nothing and commits you to nothing. If it turns out an investigation is not the best solution in your situation, we will say so honestly.

When do you hire a
private detective?

Most people only hire a detective after months of doubt. Yet there is one clear rule: as soon as a suspicion could affect your relationship, your children, your money or your business, and you cannot confirm or dispel it yourself, the moment has come. The longer you wait, the more traces disappear.

What should you check before hiring a private detective?

Not every agency delivers the same thing. Before you sign, it is worth checking these eight points.

1. Licence

Ask for the licence number of the agency and of the detective handling your case. No number means no assignment. You can have the licence confirmed before signing anything.

2. Written agreement

The law requires a written assignment agreement stating what will be investigated. An agency that skips this to «start quickly» is not working correctly and puts your case at risk.

3. Transparent pricing

You should know in advance what the hourly rate is, which costs are added and how many hours are realistically needed. A quote without an estimate of hours is not a quote.

4. Legally usable report

Ask whether the final report is drawn up in a form usable by a court, the police or an insurer. A folder of loose photos without context is not.

5. Testimony in court

Ask whether the detective is willing to testify and whether that carries a charge. Many agencies bill this separately. At Atlas Detectives testimony is free.

6. Discretion and privilege

Professional privilege is enshrined in law. Ask how your file is stored, who has access to it and what happens to it afterwards.

7. In-house team

Does the agency use its own staff or subcontractors? With us your case stays in-house, with one fixed contact you reach directly.

8. Honest advice

A good agency will also tell you when an investigation makes no sense. We do that, even if it means not getting the assignment. Promises of a guaranteed outcome are a red flag.

Step by step

Hiring a private
detective in five steps

Free intake conversation

You call or email and tell us what is going on. We listen, ask targeted questions and say honestly whether an investigation makes sense in your situation. Free of charge and without obligation.

Investigation plan and quote

We draw up a concrete plan: which findings are needed, how much time that realistically takes and what the total budget will be. In writing, before anything is set in motion.

Assignment agreement

If you agree, you sign the legally required agreement. It states exactly what we investigate and under which conditions. From then on professional privilege applies.

The investigation

Carried out discreetly using lawful methods: observation, surveillance, findings on site, verification through legal channels. You are kept informed as we go.

Report and follow-up

A detailed report with date, time, location and visual material, drawn up to be used with your lawyer, the police or the court. We testify free of charge.

What does it cost to hire a private detective?

The price depends on the type of investigation, its complexity, the number of findings required and the duration. A single evening of observation obviously does not cost the same as a fraud investigation spanning several weeks. These are the factors that determine the figure.

Type of investigation

Verifying data through legal channels is less labour-intensive than observation in the field. The type sets the baseline of your quote.

Hours and occasions

Adultery or custody cases often require several occasions to establish a pattern. A single observation rarely convinces a judge.

Number of detectives

Surveillance in heavy traffic or urban areas sometimes needs two people to stay unnoticed. That weighs on the price but raises the chance of success.

Travel

The distance to the investigation area plays a part. We are spread geographically across Belgium, which keeps travel costs limited for most cases.

Reporting included

Producing a legally usable report is part of the price, as is any testimony in court. We do not charge extra for either.

First consultation free

The introductory conversation is always free, including when it turns out an investigation is not the best solution for you. You pay only after a signed agreement.

We work with transparent rates and give you a written quote in advance, so you are never faced with surprises. One thing worth knowing: you pay for the investigation, not for a guaranteed outcome. An honest agency never promises you a particular result in advance. What we do guarantee is that you know where you stand before you sign.

What may a private detective do, and what not?

The powers are clearly delimited. A detective is not a police officer and has no investigative authority. That distinction is precisely what keeps your evidence usable.

Permitted

  • Observing and following on the public highway
  • Establishing facts with date, time and location
  • Taking photo and video material within the legal framework
  • Questioning witnesses who cooperate voluntarily
  • Requesting information through legally accessible sources
  • Reporting to you as the client, under professional privilege

Not permitted

  • Posing as police or any government service
  • Entering homes or eavesdropping without permission
  • Collecting data on health, political or religious beliefs
  • Using methods that breach privacy legislation
  • Guaranteeing results that depend on the facts
  • Working without a licence or a written agreement

That distinction is no formality: evidence obtained unlawfully can be struck from the file by a judge. Which is exactly why it is worth hiring a licensed detective rather than going after someone yourself.

Questions about hiring a private detective

The cost depends on the type of investigation, its complexity and the number of hours required. At Atlas Detectives you receive a written quote in advance with a clear hourly rate and a realistic estimate of the time needed. The first consultation is always free and we do not charge extra for testimony in court.

Yes, provided it was gathered lawfully by a licensed detective. Our report contains objective findings with date, time, location and visual material, and is usable before Belgian, Dutch and French courts. Unlawfully obtained material can be struck from the file by a judge, which is precisely why amateur work is a poor idea.

Some cases are wrapped up after a single targeted observation, others run for several weeks. We give you a realistic estimate during the intake conversation. If it becomes clear during the investigation that continuing will yield nothing further, we say so and stop, rather than keep billing hours.

Yes. A private detective's professional privilege is enshrined in law. We never disclose to third parties who our clients are or what an assignment involves. Investigations are carried out unnoticed and the person concerned is not informed.

Certainly. Many people simply call first to put their situation to us. That conversation is free, without obligation and confidential. You then decide for yourself whether to hire a private detective.

Yes. Companies engage us on suspicions of fraud, theft, time theft, breach of a non-compete clause or abuse of sick leave. We deliver a substantiated file your lawyer or HR manager can use for dismissal for urgent cause or a damage claim.

That is entirely normal. Describe your situation and we will determine together which approach fits, or tell you honestly that a detective is not the right solution here. Have a look at our method to see how a case actually unfolds.
