Current with changes from the 2024 legislative session effective on or before 7/1/2024, from Acts 2,3, 6-535, and 580-647
When property subject to a usufruct established inter vivos is encumbered to secure a debt before the commencement of the usufruct, the usufructuary may advance the funds needed to discharge the indebtedness. If he does so, the naked owner shall reimburse the usufructuary, without interest, at the termination of the usufruct, for the principal of the debt the usufructuary has discharged, and for any interest the usufructuary has paid that had accrued on the debt before the commencement of the usufruct.
