بسم الله الرحمن الرحيم
(Fatwa: 1081/838/H=9/1434)
Your mother cannot give her zakah money to you. However, she may give it to the son of your wife. And your brother may give his zakah money to you provided both of you (you and your wife’s son) are eligible to receive zakah. However, if the son of your wife is minor then it is not lawful to spend money or other things owned by him whether it is zakah money on other family members. Yes, if he is grownup then he may spend the money on family after he takes it in his complete possession. However, if both of you are not eligible to receive zakah then it is not lawful for you to receive zakah from anyone.
Allah knows Best!
