Illegal Rent Backpay for Tenants in France
An illegal rent backpay occurs when a landlord demands amounts that the law or the lease do not allow. In France, tenants can challenge such requests by asking for written justifications, checking the application of the rent reference index (IRL) and seeking conciliation before any court action[1]. This guide explains step by step how to calculate a contestable backpay, which documents to gather, which deadlines to respect and what remedies are available to protect your tenant rights.

What is an illegal rent backpay?
An illegal rent backpay can take several forms: amounts claimed beyond the lease, incorrect application of the IRL, penalties not provided for or claims without justification. If the landlord does not provide a written breakdown or if the regularization does not comply with the lease and the law, the tenant may refuse or contest the sum requested[1].
In residential leases, the law sets precise rules on rents and their adjustments.
How to calculate whether the backpay is illegal
- Compare the amount claimed with the rents actually paid (rent) for the period in question.
- Check the application of the IRL as provided by the lease and regulations (application).
- Ask the landlord for written justifications and a detailed breakdown of the sums (document, receipt).
- Gather receipts, emails and photos as proof of payment and the state of the property (photo, evidence).
- Calculate the contestable amount by identifying the exact period concerned and excluding poorly justified charges (payment).
Document all written communications with your landlord.
What to do if the backpay is illegal?
- Send a written and reasoned request to the landlord, with copies of evidence, by registered mail or tracked post (notice).
- Contact a tenant association or an information service to get initial advice and help (contact).
- Request conciliation from the departmental conciliation commission if amicable attempts fail (court).
- Take the matter to the tribunal judiciaire as a last resort if conciliation is insufficient and the amounts remain wrongly claimed (hearing).
Respond to notifications within deadlines to avoid losing your rights.
