Yeah, again, they can invalidate portions of the prenup for specific reasons. In the case of second look, that reason would be if the terms are considered unreasonable at the time of divorce. So it is fairly open ended due to "reasonable" being subjective based on the judge (or master) that you get. But the use of this doctrine is supposed to be pretty limited and should only be applied if the terms were egregiously lopsided or a significant life event occurred (disabled spouse).
