Giving Maaser money to relatives?
Tzedaka money and Maaser funds, is not only permitted to be distributed to poor relatives, but one is even required to precede a relative in need over other paupers. This includes one’s parents, one’s older children, one’s brothers, and any other relative. Nevertheless, one who has enough money to support his parents without needing to use his charity money, is not to use charity money to support them. One who nevertheless does so, a curse will befall his household. [Some Poskim suggest that it is proper for one not to distribute all of his Maaser money to his relatives, and is rather to give 50% to other paupers. If however one’s relative is in a very dire state of need, one may distribute to him all of one’s money.]
