Time is your worst enemy when dealing with property squatters. In Marseille, as in the rest of France, the “48-hour flagrance window” is the single most critical factor in legal repossessions.

If you establish and prove the break-in within the first 48 hours, police forces can intervene and expel the intruders directly on the spot. Past this window, although the 2026 anti-squat laws have speeded up procedures, eviction technically requires a more complex administrative file and formal approval from the Bouches-du-Rhône Prefect.

How can you gather rapid, bulletproof evidence when every hour counts? Here is the practical advice we provide daily to Marseille property owners, inheritances, and real estate investors.

Tangible Proof Accepted by French Police

Marseille police stations (such as in Prado or Noailles) require tangible, concrete physical evidence to initiate emergency flagrance procedures. Simple suspicions are not enough. Here are the most effective forms of proof:

  1. Smartphone App Notifications & CCTV Footage: This is the gold standard of evidence. If your phone receives a push notification indicating your front door sensor was triggered at 3:00 AM on a Tuesday, and you present this time-stamped surveillance video to the police on Wednesday, flagrance is legally undeniable. This is why we recommend installing cellular, battery-powered alarm systems on vacant properties, even if the primary electricity has been turned off.
  2. Mobile Guarding Patrol Reports: If you utilize our mobile security patrol rounds, our certified guards will instantly detect broken seals or locks during their random rounds. Their official, time-stamped report serves as clear proof of recent forced entry.
  3. Written Neighbor Testimonials: Neighbors are invaluable allies. A neighbor’s signed, honor-system statement accompanied by a copy of their ID (e.g., stating: “I heard glass breaking last night around 11 PM and saw strangers enter the backyard”) is highly persuasive in court or to police units.
  4. Logs of Your Own Recent Visits: Perhaps you visited the property yesterday to tidy up, checked utility meters, or had a viewing. Save any toll road receipts (e.g., from the Prado-Carénage tunnel), parking meter tickets, or a geo-tagged, time-stamped photo taken on your phone inside the home. These confirm the property was completely vacant within the past 24 hours.

The Danger of Unmonitored Properties

This is a classic nightmare scenario: an owner lives out of town, leaving a family home in Marseille’s 8th arrondissement empty for three months. Squatters enter quietly (often after prior routine monitoring), have mail delivered to the address to create their own “proof of occupancy” (often utility bills or online packages), and the owner only discovers the intrusion weeks later. The critical 48-hour flagrance window is lost, leading to months of stressful administrative steps.

Do Not Wait to Search for Proof: Prevent Intrusions in Advance!

Trying to prove a recent break-in is a highly stressful, race-against-the-clock process. Instead of scrambling to document when intruders entered, the safest method is to block access completely from day one.

This is where installing a temporary armored anti-squat steel door makes perfect sense. It forms an impenetrable barrier over your existing door frame. For maximum security, combine it with a wireless motion alarm that notifies your smartphone instantly if anyone approaches.

Always keep a written record (such as text messages with neighbors or logs of your visits) when your property is vacant. If you believe your current door is vulnerable, request a free security quote from our Marseille team today!

If you prove that illegal entry occurred less than 48 hours ago, the crime is classified as active flagrance, allowing the police to intervene and expel the intruders immediately without a lengthy administrative or judicial court process.

The best solution is an autonomous cellular security camera with motion alerts. On properties without electricity, we deploy 100% wireless battery-operated alarm hubs that notify your smartphone in real-time.
