Usufruct in aggregate of things; list

In the case of usufruct in an aggregate of things, the usufructuary and the owner are reciprocally obliged to cooperate in preparing a list of the things. The list is to state the date of entry and is to be signed by both parties; each party may require the signatures to be publicly certified. Each party also may require the list to be made by the competent authority or by a competent official or notary. The costs are to be borne and advanced by the person demanding that the list be prepared or certified.
