The usufructuary may claim any matured credits which form a part of the usufruct if he has given or gives the proper security. If he has been excused from giving security or has not been able to give it, or if that given is not sufficient, he shall need the authorization of the owner, or of the court in default thereof, to collect such credits.
The usufructuary who has given security may use the capital he has collected in any manner he may deem proper. The usufructuary who has not given security shall invest the said capital at interest upon agreement with the owner; in default of such agreement, with judicial authorization; and, in every case, with security sufficient to preserve the integrity of the capital in usufruct.
