If the usufructuary fails or refuses to advance the funds needed to discharge a debt secured by property subject to the usufruct, or an estate debt that is charged to the property subject to the usufruct, the naked owner may advance the funds needed. If he does so, the naked owner may demand that the usufructuary pay him interest during the period of the usufruct. If the naked owner does not advance the funds, he may demand that all or part of the property be sold as needed to discharge the debt.
