Article 598

If the usufruct be constituted on the whole of a patrimony, and if at the time of its constitution the owner has debts, the provisions of articles 758 and 759 relating to donations shall be applied, both with respect to the maintenance of the usufruct and to the obligation of the usufructuary to pay such debts.

The same rule shall be applied in case the owner is obliged, at the time the usufruct is constituted, to make periodical payments, even if there should be no known capital. (506)
