Do you have a copy of the ruling? WHEN is he required to divulge the whereabouts of her remains? What does the order say about that? Or are you just speculating?
I haven't seen a copy of the order, but its existence is reported by multiple sources.
A court order issued Tuesday gave Michael Schiavo the power to make these decisions, and also required him to notify her parents of memorial services and where the ashes will be interred.A fair inference of intent would be that her blood relatives be apprised sometime BEFORE the burial (where the ashes WILL BE interred), but even if the order reads as admitting apprisal after the burial, one would think the court expects timely communication.
No speculation, that has been reported as one of the decisions of Judgfe Greer.
