OK, seems like a DAF might be the way to go. Although i will look into the patient philanthropy fund and perhaps talk to a tax lawyer/aaron hamlin and generation pledge. I am afraid my parents would not be particularly pleased to know I am giving it away, so I will have to inherit it first. Then again, Norway does not have inheritance taxes atm, so any taxes would be small. Besides, most of the money is in the form of artworks. Just to be clear:I do intend to leave my son a small apartment, which in Oslo costs about 3-400000 perhaps. On the other hand, we are donating about 10% of our income each year, which I would also like to go into a fund that could increase in size rather than just being spent directly. Thanks everyone.
