If the person against whom the writ is served has no known domicile or residence, the bailiff shall deliver a copy of the writ to the public prosecutor’s office of the court seised.
The foregoing provisions shall apply to the service of a document concerning a legal person whose registered office is unknown.
When the public prosecutor ascertains by means of a report that a person whom he wishes to summon has no known domicile or residence or, in the case of a legal person, that its registered office is unknown, this report, which includes the particulars provided for in the second and third paragraphs of Article 551, is equivalent to a summons to appear before the public prosecutor. It allows the person to be tried in absentia according to the procedures set out in article 412.
