Yes, I know about partial disclaimers.
The biggest problem for me is that most of the expected legacy is tied up in the family RE business. Some are shares in a private company in which all shareholders are family members, while other properties are directly/jointly held with other members of the extended family.
The problem with inherited wealth is that after a couple of generations, ownership is dispersed across extended family members. No one has a majority stake and any kind of decision making becomes difficult and contentious. In my case, I have second cousins who are also shareholders in the family business whom I've never met. I know their names, but I wouldn't be able to pick them out of a police lineup. Unwinding this kind of arrangement becomes more difficult because ownership is progressively diluted as each shareholder dies off and passes his/her interests to heirs, as well as when there are family dynamics/dysfunctions involved.
While I don't plan to disclaim my legacy (it would in fact make the situation worse for other family members because then my shares would be diluted further, so I don't want to do that), I do plan to gift some of the properties away to a couple of family members where the values of my shares are minimum. For other properties in which I will inherit more substantial interests, I hope to work with other family members to dispose of them in an orderly fashion and then look into possibly setting up a charitable trust.
My ultimate goal is to unwind all of my interests in the family business before I die so that my heirs won't have to deal with this PITA. And it is truly PITA.
