provides essential evidence for court procedures

Step 4

shows the debtor that litigation is imminent

Step 5

significantly increases the likelihood of voluntary payment

What is a demand letter (mise en demeure) under French law?

A mise en demeure is a formal demand letter sent to a debtor, notifying them of their failure to fulfill an obligation (such as paying a debt). It serves as a warning that legal action will be taken if the debtor does not comply with the terms set out in the letter, typically within a specified timeframe. It is a crucial step before initiating legal proceedings.

What should be included in a demand letter (mise en demeure)?

A properly drafted demand letter should include:

  • A clear statement of the debtor’s obligations
  • A description of the breach (e.g., non-payment of a debt)
  • A specified deadline for remedy (typically 7–30 days)
  • Consequences of non-compliance, such as legal action
  • Reference to relevant contracts or legal terms

A detailed letter ensures the debtor fully understands their obligations and the repercussions of failure to act.

When is a demand letter (mise en demeure) required?

A demand letter is typically required:

  • Before taking legal action in civil disputes, including unpaid debts
  • To formally notify the debtor of a breach of contract, missed payment, or other failure to meet obligations
  • To preserve the creditor’s rights, particularly with respect to limitation periods and interest accrual

It is often an essential first step to demonstrate that reasonable attempts to resolve the issue have been made.

Can a demand letter be used for both personal and commercial debts?

Yes, a mise en demeure can be used for both:

  • Personal debts: For example, unpaid loans or unpaid invoices from individuals
  • Commercial debts: Such as overdue payments between businesses, breaches of contract, or missed service fees

The letter is versatile and can be adapted for various types of obligations.

More About Collect Your Debt

Is a demand letter (mise en demeure) legally binding?

While a mise en demeure itself is not a legally binding judgment, it is an essential procedural step. Sending this letter:

  • Establishes a formal record of the debtor’s non-compliance
  • Can be used as evidence in court if the matter proceeds to litigation
  • May lead the debtor to pay or respond to avoid legal action

It’s an important tool for demonstrating that the creditor acted in good faith before resorting to the courts.

If the debtor ignores the mise en demeure, the creditor can proceed with further legal actions, such as:

  • Filing a lawsuit to recover the debt
  • Requesting a payment order (injonction de payer) from the court
  • Taking enforcement measures, including asset seizure or garnishment

Failure to respond to the demand letter typically leads to more formal legal proceedings.

Yes, a demand letter can be sent without a lawyer, but having a lawyer draft the letter provides several advantages:

  • Ensures that the letter is legally sound and includes all necessary legal references
  • Increases the likelihood of the debtor taking the letter seriously, especially if it’s written in formal legal language
  • Helps avoid errors that could weaken the creditor’s position later on

A lawyer’s involvement adds credibility and legal weight to the letter.

Sending a mise en demeure can interrupt the statute of limitations (prescription) for debt recovery. In France, the limitation period is typically 5 years for commercial debts, but sending a demand letter may:

  • Pause the limitation period (suspension)
  • Restart the clock if the debtor acknowledges the debt (interruption)

This ensures that the creditor’s right to claim payment is preserved for longer periods, which is crucial for enforcing debts.
