It all depends, obviously, on your preferences and circumstances. A very important one has to do with being very clear about your bequest. We often remind people that to avoid any confusion or legal complications, the full legal name and address of the charity should be included in the Will. Your expression, in clear language is critical. If the issue is unclear to the tax authorities and your heirs decide to make such a gift from their inheritance, it will not qualify for an estate tax deduction.
Assets can do double duty.
This could be for a certain number of years or over someone's lifetime. Then, at a future date that asset passes to AFHU, providing estate tax savings. A Charitable Lead Trust, created through your Will, would allow you to make a gift to AFHU of an annual payment from the trust assets for a certain period of time. The net asset, with any appreciation, will go to your heirs, possibly estate tax free. Actually many charitable gifts are made by bequest for reasons that we've outlined.
