Article 50 of Code of Civil Procedure

If an action is brought within six months of the deceased's death, the plaintiff may deposit its statement of claim with the court registry and serve it on the heirs collectively in their capacities, without stating their names, at the deceased's last domicile. The plaintiff must serve the statement of claim again on all the heirs by their names and capacities, personally or at each one's domicile or workplace, before the hearing scheduled to examine the action or within the period specified by the court for serving the heirs who were not served for the first hearing and did not attend it. If the action is urgent, renewed service on the apparent heirs shall suffice. In all cases, one of the heirs may act as representative of the estate in actions brought by it or brought against it by third parties.
