Yup. One of my professors in undergrad is an attorney and he worked in family law. He taught our class that prenups are worthless in the vast majority of cases because they can be thrown out for violating an arbitrary "fairness" standard. That's code for the judge throwing anything out that would lead to the woman getting less than she would in the standard divorce rape scenario. There are some niche cases where they can help, but even then you're relying on the family court not to burn you for the crime of being male. The odds are terrible even in those very rare cases.
