Mise en Demeure Intérêts Légaux Template for France

A Mise en Demeure Intérêts Légaux is a formal legal notice that demands payment of an outstanding debt while claiming legal interest accrued on the unpaid amount. Under French law, this document serves as both a payment demand and a legal prerequisite before pursuing judicial remedies for debt recovery.

When do you need this document?

You need this document when a debtor has failed to pay an invoice or contractual obligation by the agreed deadline, and you want to formally demand payment while claiming legal interest on the overdue amount. This notice is particularly important in commercial relationships where payment delays can significantly impact cash flow. The document becomes essential when you need to establish the exact date from which legal interest begins to accrue, as this can substantially increase the total amount owed. You should also use this notice when preparing for potential legal action, as French courts typically require proof that you have formally demanded payment before filing a lawsuit.

Key legal considerations

The calculation of legal interest must comply with the annual rate set by the French government, which varies each semester according to the Law of July 11, 1975. Your notice must clearly specify the principal amount owed, the applicable legal interest rate, and the exact calculation method to ensure enforceability. Under Code Civil Article 1153, legal interest only begins accruing from the date the debtor receives your formal notice, making proper service crucial. The document must include complete identification of both parties, including SIRET numbers for businesses, and provide detailed references to the original invoices or contracts. You should also be aware that the notice period you grant must be reasonable - typically 8 to 15 days for commercial debts - and clearly state the consequences of continued non-payment.

Legal requirements in France

French law requires that your Mise en Demeure comply with specific formal requirements under Code de Procédure Civile Article 1344-1. The notice must be sent via registered mail with acknowledgment of receipt (lettre recommandée avec accusé de réception) to ensure proper legal service. For commercial transactions, you must also comply with Code de Commerce Article L441-6 regarding payment deadlines and applicable penalties between professionals. The document must explicitly state that it constitutes a formal notice ("mise en demeure") and specify that legal interest will accrue from the receipt date. If dealing with cross-border EU transactions, you should reference European Directive 2011/7/EU provisions on combating late payments in commercial transactions. Additionally, the notice must provide the debtor with a clear deadline for payment and warn of potential legal consequences, including the possibility of judicial proceedings and additional costs recovery.
