§1. In real actions, whenever the petitioner is awarded something, it must be handed over to the petitioner as soon as there is a res iudicata.
§2. In personal actions, when the guilty party is condemned to furnish a movable thing, to pay money, or to give or do something else, the judge in the text of the sentence or the executor according to his or her judgment and prudence is to establish a time limit to fulfill the obligation; this time limit, however, is not to be less than fifteen days nor more than six months.
