Charity

May I include wedding gifts as Hachnasat Kalah in my Tzedakah donations calculation?

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?
