Public attitudes toward prenuptial agreements are mixed according to a study. While some see value in allowing couples autonomy to decide divorce outcomes privately, others worry it is too difficult to predict fairness far in the future. Survey results found most felt both partners should have legal advice but views varied depending on marriage length and children. Overall prenups were seen as more appropriate for short childless marriages than long-term marriages where one spouse sacrificed their career. Concerns included agreements undermining marriage and being inherently unfair if circumstances change substantially.
