Was to be expected. The Sussexes have already filed their papers for their foundation. The split is complete.
I guess via papers they haven't, similarly to this foundation. Legally it is still titled with the Sussexes as well (for now) though in practice they separated for months now. It made sense as they hadn't put their team in place yet so keeping KP logistics made sense. I would guess by the tour that the transfer will be complete.
