What is a "Letter with proof of receipt"?

The letter with proof of receipt is a postal service allowing anyone who sends a letter to receive proof of its good receipt, signed by the recipient.

In France, this form of the letter allows to legally establish :

• A proof that you sent a letter.
• A proof that the recipient received the letter.
  
  That's why this is the only legal process you can use to stop your contract and be out of financial engagement.
  
  You can even send this letter through the La Poste website. We kindly advise you to use the google translation plugin to your browser to understand fully the process even though the letter HAS to be in french.
