Gail, I have experience with a trust trying to claim a charitable deduction on a 1041--the rules are very strict on the language of the trust document, and in my case, there was no deduction for a $100,000 donation. Not sure if same goes for an estate, but I suspect that the charity must be named in the will and possibly it must designate that income go to the charity, otherwise it is assumed to come from corpus. I'll take a look see if no one knows the answer off the top of their head.
