Unpaid invoice or unperformed contract: what steps can you take?

November 10, 2026

Key point: every case depends on its facts, supporting documents and applicable time limits. An individual assessment is needed before taking action.

Checking the debt and the contract

Before starting proceedings, check the contract, general terms, accepted quotation, evidence of delivery or performance, invoice and due date. A debt pursued through a payment order must, in particular, be certain, of a determined amount and due.

Identify the debtor correctly as well. An error in the company name, address or the contracting party’s capacity may delay recovery.

Reminder and formal notice

A reminder may resolve an administrative delay, but does not always replace a properly structured formal notice. The notice should state the source and amount of the debt, the time allowed and the intended consequences of non-payment.

Keep proof of sending and receipt. Where the contract contains a termination clause, its wording and the requirements of the Civil Code must be respected before claiming to terminate on that basis.

Choosing a recovery procedure

If payment is not made, the creditor may consider an application for a payment order or court proceedings for payment. Jurisdiction depends on the nature of the debt and the parties’ status. A simplified procedure through a commissaire de justice is available for certain small claims.

A payment order is suitable for sufficiently established debts. Where the debt is seriously disputed or detailed contractual analysis is needed, proceedings in which both sides are heard may be more appropriate.

Non-performance and termination

Article 1217 of the French Civil Code lists several remedies for non-performance, including enforced performance, price reduction, termination and compensation for the consequences. Unilateral termination has conditions and risks: the creditor must, in particular, be able to justify the seriousness of the breach.
