If a father borrowed money in order to help pay his married son’s rent and now the father is stuck with the debt and is finding it difficult to repay, may the son help the father repay the loan with his maaser money?
Answer:
Yes, this is permitted.
As we have noted in the article and piskei din on charity, a person’s first priority in donating charity money is to his immediate family, and it is certainly permitted to aid a father in need.
There is no concern for ribbis here, because there is no loan from father to son.
Best wishes.
