Usufruct of perishable objects

If the usufruct includes things susceptible to deterioration by use, the usufructuary shall not be bound to do more than returning them at the end of the usufruct, as they are, except if they have deteriorated by an use different from that for which they were meant or by default or negligence of the usufructuary. § Sole paragraph - If the usufructuary does not return them, he shall be liable for the value which they had at the stage when the usufruct started, unless he proves that they were consumed in the process of their legitimate use.
