During the investigation in flagrante delicto or the preliminary investigation, the liberty and custody judge, at the request of the public prosecutor, may order, by reasoned decision, the seizure, at the advanced expense of the Treasury, of the real estate whose confiscation is provided for by the article 131-21 of the Penal Code. The investigating judge may, in the course of the investigation, order this seizure under the same conditions.
The decision taken pursuant to the first paragraph is notified to the public prosecutor, the owner of the property seized and, if known, third parties with rights in the property, who may refer it to the investigating chamber by declaration at the court registry within ten days of notification of the decision. This appeal does not have suspensive effect. The appellant is only entitled to have the documents relating to the seizure he is contesting made available to him. If they are not appellants, the owner of the property and third parties may nevertheless be heard by the investigating chamber, without however being able to claim that the proceedings will be made available.
