516. The purpose of a seizure before judgment is to place property in the hands of justice while a proceeding is pending. A seizure before judgment is carried out in the same manner and according to the same rules as a seizure after judgment, subject to the rules of this chapter.
A seizure before judgment may be carried out before the commencement or in the course of a proceeding or while the case is under appeal, but in the latter case with the authorization of the court of first instance.
A third person is given custody of the seized property, unless the seizor authorizes the bailiff to leave the property in the custody of the person from whom it is seized.
