The obligation to give support shall also cease:
(1) Upon the death of the recipient;
(2) When the resources of the obligor have been reduced to the point where he cannot give the support without neglecting his own needs and those of his family;
(3) When the recipient may engage in a trade, profession, or industry, or has obtained work, or has improved his fortune in such a way that he no longer needs the allowance for his subsistence;
(4) When the recipient, be he a forced heir or not, has committed some act which gives rise to disinheritance;
(5) When the recipient is a descendant, brother or sister of the obligor and the need for support is caused by his or her bad conduct or by the lack of application to work, so long as this cause subsists. (152a)
