Tenant recourse for APL simulation in France

Social housing, housing aid & DALO 3 min read · published September 11, 2025

Receiving a notification from the CAF alleging an "APL simulation" can be stressful for a tenant in France. This text explains, in simple terms, what your rights are, which evidence to gather (rental contract, tax notice, rent receipts, correspondences) and the first steps to take with the CAF or via a departmental conciliation commission. You will also find the deadlines to respect and the stages if you must bring the matter before the judicial court. The aim is to help you protect your tenant rights without unnecessary legal jargon and with concrete actions to take quickly.[2]

What to do immediately

Act quickly but calmly. Here are the priority steps for a tenant facing an APL simulation:

  • Gather all evidence related to your housing situation: lease, inventory, receipts and letters.
  • Contact the CAF to request the written justification of the "simulation" and a calculation statement.
  • If the response is insufficient, request mediation via the departmental conciliation commission (CDC).
  • As a last resort, prepare a file for the judicial court if the situation is not resolved.
Keep digital and paper copies of all documents upon receipt.

Useful evidence and how to organize it

The most useful documents are the rental contract, the tax notice, CAF statements, rent receipts and any written exchanges with the landlord or CAF. File them by date and make timestamped digital copies if possible. Photos and screenshots of listings or housing terms can also help.

A clear timeline of events makes your file easier to read for a conciliator or judge.

Deadlines and procedures

Always reply to registered letters within the indicated deadlines. To dispute a calculation or decision of the CAF, follow the administrative prior recourse procedure when applicable, then refer to the CDC or the court as appropriate. Deadlines vary according to the nature of the decision; acting quickly preserves your rights.[1]

Respond to CAF letters within deadlines to avoid losing your rights.

Concrete actions examples

  • Send a copy of the lease and receipts to the CAF by registered mail with acknowledgment of receipt.
  • Request contact with your department's CDC if the dispute persists.
  • Prepare a file with a timeline, evidence and copies of all steps before seizing the judicial court.
