Yes, the principal reason somebody would enter into a prenuptial agreement would be to set their own rules, so to speak, in terms of how they would divide a marital estate in the event of one spouse’s death, and/or a divorce. Those are valid and binding contracts, and so long as there's full and fair disclosure at the time that those agreements are made, and however those agreements are written, those will carry the day at the point in time when somebody looks to get divorced.
