Charity

I learned that one should prioritize giving tzedaka to relatives over others. I give a nice amount of tzedaka, almost exclusively out of the family (which also has a few poor people), which I feel is more altruistic. Can you explain this halacha and give some halachic guidelines?

Over the years, I have received cash gifts for birthdays, bar mitzva, etc. and never gave ma’aser kesafim (=mk) from them. I would like to do so now but do not remember the exact amounts I received. What should I do?

the Citigroup “bank” mistakenly paid some $900 mil. to Revlon’s creditors before the loans were due. A few big creditors refused to return the money. A court ruled that since the creditors took the money (they were owed) in good faith, they need not return it. Would the halachic ruling be the same?

Why do we give it? Who needs to give it? How much is one obligated to give? When and to whom should one give it?

Do we have to allow beggers from out of the city to come and collect donations in our city? r\Rav Neventzal answers with a story from the Gr"a.

I was told that the "Paybox" app that allows sending money enables payments only of full shekalim. So when my wife and many others use it to repay a friend who bought something at the grocery that has an agurot element, they must round the numbers. Is rounding up a problem of ribbit?

May one to decide not to go through with his donation pledge to a Jewish school? If so, must he take steps such as hatarat nedarim?
