He better have learned his lesson on marriage and put an iron clad prenup. I would imagine you are right he did. I would think 50K per year for a total of 150K. No way SHOULD she get more. However, courts can screw the guy big time.
He probably does but there is no such thing as an "ironclad" prenup, even if it's a "Massey Pre-nup" in the "non-community property" NY state.
Though most of his assets predate their marriage, they were much smaller in 2014 when they got married (began dating in 2011), they have two young children and she is 9 month pregnant with their third.
Like another hedge-fund manager, Martin Shkreli, Scaramucci is not exactly an endearing personality, despite fake outward "charm" which Shkreli lacks. His new high-profile status and latest profanity-laced interview will not be helpful in the divorce court and the court of public opinion. Expect that besides the divorce settlement, alimony is going to be very substantial and for a long time.
