In Belgium you can support 'a good cause' at the time of your death by giving away a piece of inheritance. That charity could also be Rainbow4Kids. The 'duo bequest' is interesting for the heirs of the deceased, because Rainbow4Kids will pay part of their inheritance tax. Your notary can certainly tell you more about it. He'll ask you what charity he can mention. That's 'Rainbow4Kids non-profit organization'. He's going to need our company number, too.
That's BE 0886.676.109. More information about this can be received at Katrien Vermeersch firstname.lastname@example.org.
There is also a brochure ('Make a difference, a good cause in your will') which you can download here.
