When Article R. 442-2, the clerk’s office notifies the claimant by any means of the place, day and time of the hearing.
The defendant is summoned by registered letter with acknowledgement of receipt. This letter contains a copy of the claim, informs the interested party that, failing to appear or to make known his means of defence, he risks being judged solely on the basis of the information provided by the claimant, and reproduces the provisions of articles R. 121-6 to R. 121-10. This summons may also be given verbally against a signature.
If the registered letter is returned to the court clerk’s office and could not be delivered to its addressee, the court clerk informs the claimant and invites him to proceed as stated in article 670-1 of the Code of Civil Procedure.
