Answer
The usufructuary is entitled to all the natural, industrial, and civil fruits of the property, and may generally use it as an owner would, provided he preserves its form and substance. Before entering upon the enjoyment, the usufructuary must make an inventory of the property and give security (Article 583) — though parents who are usufructuaries of their children's property and a donor who reserves the usufruct are exempt from posting security.
The usufructuary must care for the things as a good father of a family, make ordinary repairs, and return the property at the end of the usufruct. A usufruct is extinguished by the death of the usufructuary, the expiration of the period or fulfillment of the resolutory condition, the merger of the usufruct and ownership in one person, renunciation by the usufructuary, the total loss of the thing, the termination of the right of the person constituting it, and prescription (Article 603).
