Marseille private detective: solid facts for your case
Adultery, divorce proceedings, contested child custody, concealed lifestyle; on the employers' side, sham sick leave, unfair competition, stock diversion. Your private detectives in Marseille operate from the street and publicly accessible locations, without wiretapping, without tracking devices, and without entering anyone's premises. You then receive a detailed report, supported by dated photographs. The report can be submitted in court; the judge assesses its value.
Every interaction with your detectives is protected by professional secrecy. The free quote and the review of your request do not commit you to anything; generally allow 24 hours for a response. Your private investigation agency in Marseille is located at 565 Avenue du Prado, in the 8th arrondissement, just a few streets from the Prado beaches.

Other situations
Illegal wiretaps, threats, inheritance: get proof safely
Mouchard discovered in a vehicle, anonymous messages repeated, elderly relative isolated by a third party, estate blocked: your detectives choose a method adapted to the place and the stakes.Apartment of the Basket, villa of the South neighborhoods, residence of Valentine: in each case, the perimeter of the mission is specified in writing. In case of emergency, the 17 must be your first call; the 3919, free and anonymous number, directs victims of domestic violence.
Companies of Bouches-du-Rhône
Marseille detective for businesses, from Euroméditerranée to La Valentine
Euro-Mediterranean towers, harbour terminals, areas of activity in the valley of the Huveaune, Valentine's shops: the Marseille economy does not escape abusive absenteeism, or diversion of customers, nor theft. A sanction or subpoena requires established facts before any decision is made. Your detectives get them without ever getting out of the legal framework.
sick leave and hidden activity
The labour court recalled on 26 February 2020: engaging in work during a leave only becomes wrongful in the event of harm suffered by the employer. The assignment therefore focuses on elements that establish this damage.
Activity monitoring
Shortened rounds, overtime declared but not worked, company vehicle lent to a third party: surveillance only begins on serious indications. The judge only permits the surveillance of an employee if the measure remains proportionate and no other means can establish the facts.
Unfair competition
Theft and embezzlement
Research and verification
Marseille: find a loved one or a debtor, assess assets
Change of district, installation in Aubagne or La Ciotat, departure to Corsica or abroad: a person can cut the bridges very quickly. The reason given must be legitimate; your private investigation agency in Marseille controls it first. Next comes the crossing of licit sources and confirmation on the spot.
Loved one to locate
The research respects the subject matter of the written agreement; the person found remains free to answer or not.
Blocked debt recovery
State of assets
Apparent property, vehicles, shares in companies: a lawful balance sheet before pleading or negotiating an agreement.
Due diligence
Before a buy-in, take-up or partnership, your detectives control the real existence of the activity and the course of the leaders.
Trade rules
Marseille: a private investigation under legal control
"Prove, yes; at any price, no."
A legitimate goal
Defend a right, prepare a trial, establish a fact: this objective is written into the written agreement.
Clear rules
No interception of communications, no beacon unseen by the person, no intrusion, no hacking.
A suitable measure
The extent of monitoring follows the seriousness of the facts to be demonstrated.
The judge's perspective

The report can be brought to justice; the judge appreciates its value. A local court also sits in Aubagne.

An investigation in Marseille in five steps
Before each step, you know what will be done and what it costs.
Interview
You set out the context; your detectives appreciate the legitimacy and feasibility of the request.
Mandate
The written contract sets out objectives, means, limits and prices, based on a free quotation.

The payment of an advance, usually half the quotation, initiates the mission.

Your detectives in Marseille deploy the agreed arrangements and inform you as soon as a significant fact occurs.
Delivery
You receive a chronological file, photographs attached, ready for your lawyer.
Means engaged
Tunnels, hills, metro: an arrangement adapted to Marseille
The most probable route determines the arrangement: walking, metro, car, often a combination of the three.
Urban and road surveillance
In the lanes of the Basket, on the A50 or in a subway train, your detectives adapt the distance and means of transport to the person being followed.
Photos and videos
Made from public space, the images respect the privacy of the person and are limited to what the mission requires.
Written statements
A witness handwritten a signed and dated certificate, accompanied by a copy of an identity document.
Beyond the department
If the person takes the A7 towards Lyon or the A8 towards Nice, another Investipole agency resumes supervision.
discreet surveillance in Marseille and the metropolis
Marseille on surveillance: hills, tunnels, coast
Marseille extends in an amphitheater around the Old Port, backed by hills and open to the sea. Its districts alternate village nuclei, large ensembles and coastline: for a private investigator in Marseille, relief and distances dictate preparation.
Tunnels complicate any follow-up by car: Prado-Carénage between Prado and the Old Port, Vieux-Port tunnel, Joliette tunnel, Prado Sud. In a tunnel, a missed exit cannot be recovered; a vehicle therefore waits at each likely exit.
The motorways radiate from the city: the A7 towards Lyon, the A51 towards Aix, the A55 towards Martigues, and the A50 towards Aubagne and Toulon. The L2 ring road connects the A7 to the A50 via the north and east; your detectives locate its junctions prior to any motorised surveillance.
In terms of public transport, the M1 metro connects La Rose to La Fourragère and the M2 runs from Gèze to Sainte-Marguerite Dromel; the two lines intersect at Saint-Charles and Castellane. The T3 tram has been operating between Gèze and La Gaye since January 2026. Your detectives take up positions on platforms and exits as soon as a train is in operation.
From the Vieux-Port to the Prado, heavy traffic, scarce parking and pedestrianised streets often necessitate walking. Around Saint-Charles station and the Joliette docks, the crowd is constantly replenished.
Surveillance ceases at the threshold of any private premises. Key transition points are therefore anticipated: tunnel exits, metro stations, L2 interchanges, car parks. Billable hours are thus concentrated on decisive moments.

A word from the Manager
"Diriger Investipole in Marseilles for almost 20 years has been doing this job with an intact passion and constant demand. The metropolis imposes a real reading of the terrain: discreet supervision can start at Prado, continue to the Old Port, switch to the quays of the Joliette or borrow the A7. In each case, our role remains the same: checking the facts accurately, preserving the confidentiality of the client and providing a useful report to both lawyers and competent courts."
David LIOBARD, Managing Director

Your questions
Private detective at Marseille: fifteen questions, fifteen answers
It is essential to make an informed decision.
Marseille: how much does a private investigation cost?
The rate for a private detective in Marseille ranges from €90 to €120 excluding VAT per hour depending on several criteria, with a free estimate. The final price depends on the time spent, night or Sunday hours, the personnel deployed and the distance travelled. Your written agreement precedes any expenditure.
Surveillance at Marseille: what does the law say?
Following a person is permitted when a legitimate interest requires it, without undue harm to privacy. Observations are made from the street or places where everyone can enter freely. The judge controls this balance if the measure is contested.
How do you deal with tunnels during surveillance at Marseille?
Each tunnel is treated as a breaking point: a vehicle is positioned at the exit before the person engages in it, a second follows it from a distance. The same principle applies to L2 shoulder straps.
Marseille and surroundings: how far will your detectives go?
Throughout the metropolis, from Aubagne to Vitrolles and La Ciotat to Marignane, then in the rest of the Bouches-du-Rhône, until Arles and the Camargue. The Var and Vaucluse are also accessible when the file requires it.
How far should you follow someone leaving Marseille?
Up to the limit set by the written agreement: by A7, A8, A50 or A55. Beyond this, the mission moves to another Investipole agency, without change of responsible.
Child's residence in Marseille: what facts to note?
Missed or delayed discounts, the presence of a third party in charge of the child, short stays or cancellations. Your detectives note them remotely, without contact with the child; your lawyer then submits them to the judge.
Marseille: can you follow an employee?
It is possible under conditions: a legitimate reason and concrete indications of competition, theft, fraud or activity during a judgment. Supervision is limited to facts useful to the dispute and remains proportionate; the judge monitors its necessity.
