What you've stated is very interesting. Irrevocable dynasty trusts can be very attractive to some who have wealth and who want to keep the wealth in the family. But one can only financially control their own children from the grave. The grandchildren are the ones who typically inherit the real wealth in this kind of trust, when the parent for whom the trust was established dies. Grandchildren can really screw things up for the family dynasty when they reproduce with a young woman who refuses to continue to be abused and who leaves, takes her child and refuses to sign over custody and her family was standing firmly behind her.
Irrevocable trusts cannot be changed once they are established. The W's did some funky things with the custody docs. If there was a trust, it may have been set up that if BW died before AW died, the monthly income he received from the trust ended. That would leave AW without income. But the sons she controlled would have a lot of money to provide for her but if they died before AW died, the money would go to their children. The custody docs were worded so AW got custody if either or both her sons died before her. If that happened, that would give AW control of her grandchildren's money.
I could be way off and this is pure speculation, but it is something I've considered as a possibility. Dewine said it was about control and custody of children, but he did not elaborate further. It may have been about control of the W money.
