1- As a grandparent can maaser money be given to their adult children to help them
Pay for yeshiva education for the grandchildren?
2- can a family inviting guests Shabbos and yomtov be a halachic way to utilize maaser kesafim?
- If your children need the help with the tuition, and they are having a hard time making ends meet, you can give them money to help them pay for the tuition from maser money.
- Usually not, but it depends why you are inviting them. If it is because they don’t have money, then it is considered tzedakah. If, however they are not needy, then it isn’t tzedakah, but it might be hachnosas orchim, if they don’t have a place to eat.
